We had such a great time speaking at Security Field Day recently, presenting the changes to our product since our last visit, and hearing from delegates about what issues concern them in micro-segmentation technology.
The last time we were at Field Day was four years ago, and our product was in an entirely different place. The technology and vision have evolved since then. Of course, we’re still learning as we innovate, with the help of our customers who continually come up with new use cases and challenges to meet.
For those who missed our talk, here’s a look at some of what we discussed, and a brief recap of a few interesting and challenging questions that came up on the day.
Simplicity and Visibility First
At Guardicore, we know that ease of use is the foundation to widespread adoption of a new technology for any business. When we get into discussions with each enterprise, customer, or team, we see clearly that they have their own issues or road map to address. As there is no such thing as the ultimate or only use case for micro-segmentation, we can start with the customer in mind. Our product can support any flavor, any need. Just as examples, some of the most popular use cases include separation of environments such as Dev/Prod, ring fencing critical assets, micro-segmenting digital crown jewels, compliance or least privilege and more general IT hygiene like vulnerable port protocols.
To make these use cases into reality, organizations need deep visibility to understand what’s going on in the data center from a human lens. It’s important to have flexible labeling so that you can physically see your data center with the same language that you use to speak about it. We also enhance this by allowing users to see a particular view based on their need or their role within the company. A compliance officer would have a different use for the map than the CTO, or a developer in DevSecOps for example. In addition, organizations need to enforce both blacklist and whitelist policy models for intuitive threat prevention and response. Our customers benefit from our cutting edge visibility tool, Reveal, which is completely customizable and checks all of these boxes. They also benefit from our flexible policy models that include both whitelisting and blacklisting.
To learn more about how our mapping and visibility happen, and how this helps to enforce policy with our uniquely flexible policy model as well and show quick value, watch our full presentation, below.
Addressing Questions and Challenges
With only one hour for presenting our product, there were a lot of questions that we couldn’t get to answer. Maybe next time! Here are three of the topics we wanted to address further.
Q. How does being agent-based affect your solution?
One of the questions raised during the session was surrounding the fact that Guardicore micro-segmentation is an agent-based solution, as the benefits are clear, but people often want to know what the agent’s impact is on the workload.
The first thing we always tell customers who ask this question is that our solution is tried and tested. It is already deployed in some of the world’s biggest data centers such as Santander and Openlink, and works with a negligible impact on performance. Our agent footprint is very small, less than 0.1% CPU and takes up 185MB on Linux and 800MB on windows. Our resources are also configurable, allowing you to tailor the agent to what you need. At the same time, we support the largest amount of operating systems as compared to other vendors.
If the agent is still not suitable, you can use our L4 collectors, which sit at the hypervisor level or switch level, and give you full visibility, and use our virtual appliance for enforcement, as we touched upon during the talk. As experts in segmentation, we can talk you through your cybersecurity use cases, and discuss which approach works best, and where.
Q. Which breach detection capabilities are included?
Complementary controls are an important element of our solution, because they contribute to the ease of use and simplicity. One tool for multiple use cases offers a powerful competitive edge. Here are three of the tools we include:
- Reputation Analysis: We can identify granular threats, including suspicious domain names, IP addresses, and even file hashes in traffic flows.
- Dynamic Deception: The latest in incident response, this technique tricks attackers, diverting them to a honeypot environment where Labs can learn from their behavior.
- File Integrity Monitoring: A prerequisite for many compliance regulations, this change-detection mechanism will immediately alert to any unauthorized changes to files.
Q. How do you respond to a known threat?
Flexible policy models allow us to respond quickly and intuitively when it comes to breach detection and incident response. Some vendors have a whitelist only model, which impedes their ability to take immediate action and is not enough in a hybrid fast-paced data center. In contrast, we can immediately block a known threat or undesired ports by adding it to the blacklist. One example might be blocking Telnet across the whole environment, or blocking FTP at the process level. This helps us show real value from day one. Composite models can allow complex rules like the real-world example we used at the presentation, SSH is only allowed in Production environment if it comes from Jumpboxes. With Guardicore, this takes 2 simple rules, while with a whitelist model it would take thousands.
Until Next Time!
We loved presenting at Field Day, and want to thank all the delegates for their time and their interesting questions! If you want to talk more about any of the topics raised in the presentation, reach out to me via LinkedIn.
In the meantime, learn more about securing a hybrid modern data center which works across legacy infrastructure as well as containers and clouds.

The Ponemon Institute has found that the survival rate for businesses without a security incident response plan is just 10%. Enterprises will often focus on creating a strong security posture to detect and thwart attackers, but fail to detail what to do if and when a breach actually occurs. That’s not unusual; it can feel defeatist to prepare for the worst. However, with new attacks being discovered all the time, and increasingly connected networks putting us all at risk, an incident response plan is essential.
1. Understanding the Consequences of Ignoring a Security Incident Response Plan
The first stage in your security incident response strategy needs to be recognizing the ramifications of an attack. From the obvious problems, such as asset and data breach, to reputational damage, compliance failures and public image breakdown, it’s in your company’s best interests to be fully prepared. Detailing these threats in writing can help your staff focus on maintaining a strong security posture to prevent attacks, and encourage everyone to work together with a mutual understanding of what’s at risk if the worst happens.
2. Assigning Roles Before an Emergency
Especially in large organizations, it can be hard to keep everyone in the loop when there is a crisis. Identifying the core stakeholders for a security incident before a breach occurs is therefore essential. Here are some key personnel who need to be detailed in your security incident response plan. In some cases they may be obvious, while in others you might need to choose staff to take on responsibilities for some of these roles in your cyber-security incident response team.
- Incident response managers . It’s worth having at least two members of staff on hand who can oversee and prioritize the incident response plan, communicating information and tasks throughout the business.
- Security analysts. Maintain the investigation, support the managers in following the plan, and filter out false positives. They may also alert others to potential attacks. It’s essential to ensure that they are given the right tools to be able to manage their role effectively.
- Threat researchers. These personnel will be the port of call for contextual information around a threat. Using the web, as well as other threat intelligence, they can build and maintain a database of intelligence internally.
- Key internal stakeholders. Who needs to be kept in the loop when a threat occurs? From board level personnel who may need to sign off on your actions or give the go-ahead for your response plan, to your CISO or human resources representative if human error is involved.
- Third-party organizations, such as legal counsel, law enforcement, forensics experts or breach remediation companies.
3. Create a High-Level Document Outlining the Security Incident Response Procedure
Many organizations have multiple playbooks with granular detail on the technical side of an attack, in order to help IT manage and contain a breach. However, if you’ve ever experienced a security incident, you know that IT are far from the only department affected by an attack. Your incident response plan needs to be easily communicated and understood by C-suite employees, Human Resources, Vendor Management and all other lines of business stakeholders including global offices or teams in the field. As regulation increasingly dictates that customers are kept informed when their data is at risk, you may even need customer experience managers to be able to relay your position.
Some of the best security incident response plans are one or two pages, and give a high-level overview of how to manage the consequences of an incident. While playbooks might hold specific information for targeting a type of attack, such as Ransomware, your incident response plan should be written so that it can be read by anyone and understood easily in a moment of crisis.
4. Outline Response Priorities
Not every key stakeholder is going to have the same priorities when an attack hits, and not all priorities can be taken into consideration. For example, your board might want to get your operations up and running as quickly as possible, while legal counsel may suggest staying offline until vendors have been notified or customers contacted. Without a clear outline of whose priorities take precedence, existing relationships can dictate what procedure is followed after a breach, following tribal knowledge rather than smart decision making.
Assessing the scale of an attack and making quick decisions about revenue over security for example should not be done in the moment, or by whomever has the ear of the CISO that day. While you’re building your incident response plan, think about who should have autonomy over decisions that manage risk, and engage them in creating priorities based on levels of threat.
Detailed performance objectives can help here. In the event of a customer data breach, your security team might be tasked with finding out what has been exposed and how many customers are affected within a given amount of time. Making smart decisions about the action needed before a problem becomes a reality means all relevant teams can hit the ground running.
5. Simulate Breaches to Troubleshoot in a Safe Environment
Having an incident response plan is not enough in and of itself. Without testing and simulation, there is no way to recognize gaps in protocol or resources, or to uncover changes in third-party procedure. Regular simulations can ensure that your security incident response strategy remains up to date and nothing falls through the cracks. This can include finding replacements for staff who took on security roles and have now left the company, or for external vendors with lapsed service agreements. It can also help you keep up with changes in regulation, and keep new staff informed of the process in case of a breach.
A simulation can be as in-depth as you would like and can range from table top exercises to injecting your system with a known and containable malware, but a few basics to cover include:
- Going over the lines of communication from detection to resolution
- Understanding who is authorized to make decisions on security and risk
- Confirming you have the third-party services in place you need to control a breach
- Who needs to be contacted in case of a breach for continued regulatory compliance/operations?
The more you make simulation and testing part of your usual security posture, the more likely it will be second nature for the relevant stakeholders when the incident is no longer theoretical.
6. Identify the Scope of a Breach
Many companies act too quickly when they see a threat. Failing to recognize the size of a breach can cause more problems in the long run. Finding one point of entry does not mean that you’ve identified all the endpoints that have been compromised for example. Acting like you have found patient zero when it’s actually patient 10 or 15 can slow down recovery time overall. Modern day attacks are stealthy and subtle, and could have caused more damage than you might have first assumed.
The best security solutions will intercept suspicious activity on threat detection and reroute it to where it cannot do any harm using dynamic deception. The full extent of the breach can then be searched for and contained in real-time, giving your security team an accurate dynamic map of your entire data center and network. Your automatically generated report shows you the deception incidents, including integral information you need to investigate the breach. What passwords were used, and where did the attacker gain entry? Were there malicious binaries used, or suspicious C&C servers? With this level of detail, your security teams are able to start building up a clear picture of root cause.
Containment of this kind can also give you more time to understand what you’re dealing with in a safe environment. By rerouting an attacker using dynamic deception, you can isolate them safely, and monitor and learn from their activities rather than frighten them away by alerting them that you know they’ve gained entry. In this way, you can take back the upper hand, responding to the attackers behavior without going into crisis mode, calmly following your incident response plan priorities – risk free.
7. Limit Dwell Time
Having this level of granular visibility manages the next part of your incident response plan, limiting the amount of time that attackers are on your network. The SANS Institute found that a shocking 50% of organizations didn’t notice a breach for more than 48 hours, while 7% had no idea how long an attacker had breached their network for, even after the fact. The longer an attack continues for without being stopped, the more damage can be done, so having a plan for limiting this is essential.
Your security solution should be able to limit dwell time by provide application layer visibility. This uncovers and tracks process-level activity (not just at the transport layer) across applications in real-time. This can then be automatically correlated with network events and context, allowing you to access reports on suspected incidents and any anomalies detected across all workloads. With this, even new attack vectors are isolated in real-time. With nowhere for attackers to hide, dwell time is automatically minimized at a policy level.
8. Including Recovery Plans
The clearest part of your security incident response plan should outline what happens when a breach has been confirmed. Detail the processes that are automated so that all key stakeholders understand what has already been put into place.
Does your security solution allow IOCs (Indicators of Compromise) to be automatically exported to your SIEM or security gateways to speed up incident response? Can you update your micro-segmentation policies quickly and seamlessly in response to traffic violations? There might be different automated procedures needed for various environments. For example, stopping the spread of damage from VMs or Containers could involve an IOC halting or disconnecting service entirely. The best solutions will provide an integrated platform that shows the full picture from both a security and an infrastructure point of view.
Recovery plans might need their own smaller security incident response plans or playbooks. A DDoS attack is different from an injection of malware. An external bad actor is a different adversary from an insider with high level access who has compromised the network. Your company might have one set of response plans for a breach to customer data, another for artificial intelligence, and yet another for asset recovery. Make sure the right documentation is ready for any event, and the right personnel are equipped with a plan of action.
9. What Lessons Can You Add to Your Security Incident Response Plan?
By utilizing a smart incident response plan, you can use a breach to help prepare for the future. Once the attack is contained and eradicated, make sure to complete any incident documentation for regulation or internal records. You can also perform your own analysis internally to learn from the attack and your responses to it as a company. With the lessons you’ve learned, you can update your security incident response plan. What can you improve for next time, and what gaps did you uncover if any?
A strong security incident response plan is a must-have in today’s increasingly interconnected IT environment. If and when a breach occurs, your business will be asked how you prepared for an incident. This could be used to establish regulatory compliance as well as assessment of the attack and even blame. Creating a detailed analysis of how your company prepares for a threat, as well as responds in the moment and learns from the experience puts you one step ahead, and ready for anything.

Honeypots are systems on your network that attract and reroute hackers away from your servers, trapping them to identify malicious activities before they can cause harm. The perfect decoy, they often containing false information, without providing access to any live data. Honeypots are a valuable tool for uncovering information about your adversaries in a no-risk environment. A more sophisticated honeypot can even divert attackers in real-time as they attempt to access your network.
How Does Honeypot Security Work?
The design of the honeypot security system is extremely important. The system should be created to look as similar as possible to your real servers and databases, both internally and externally. While it looks like your network, the actual honeypot is a replica, entirely disparate from your real server. Throughout an attack, your honeypot is able to be monitored closely by your IT team.
A honeypot is built to trick attackers into breaking into that system instead of elsewhere. The value of a honeypot is in being hacked. This means that the security controls on your honeypot need to be weaker than on your real server. The balance is essential. Too strong, and attackers won’t be able to make a move. Too weak, and they may suspect a trap.
Your security team will need to decide whether to deploy a low-interaction honeypot or a high-interaction honeypot. A low-interaction solution will be a less effective decoy, but easier to create and manage, while a high-interaction system will provide a more perfect replica of your network, but involve more effort for IT. This could include tools for tricking returning attackers or separating external and internal deception.
What Can a Honeypot Cyber Security System Do?
Your honeypot cyber security system should be able to simulate multiple virtual hosts at the same time, assign hackers with a unique passive fingerprint, simulate numerous TCP/IP stacks and network topologies, and set up HTTP and FTP servers as well as virtual IP addresses with UNIX applications.
The type of information you glean depends on the kind of honeypot security you have deployed. There are two main kinds:
Research Honeypot: This type of honeypot security is usually favored by educational institutions, researchers and non-profits. By uncovering the motives and behavior of hackers, research teams such as Guardicore Labs can learn the tactics the hacking community are using. They can then spread awareness and new intelligence to prevent threats, promoting innovation and collaboration within the cyber security community.
Production Honeypot: More often used by enterprises and organizations, production honeypot cyber security measures are used to mitigate the risk of an attacker on their own network, and to learn more about the motives of bad actors on their data and security.
These honeypots have one particular element in common: the drive to get into the mind of the attacker and recognize the way they move and respond. By attracting and tracking adversaries, and wasting their time, you can reinforce your security posture with accurate information.
What are the Benefits of Honeypot Security?
Unlike a firewall, a honeypot is designed to identify both internal and external threats. While a firewall can prevent attackers getting in, a honeypot can detect internal threats and become a second line of defense when a firewall is breached. A honeypot cyber security method therefore gives you greater intelligence and threat detection than a firewall alone, and an added layer of security against malware and database attacks.
As honeypots are not supposed to have any traffic, all traffic found is malicious by its very existence. This means you have unparalleled ease of detection and no anomalies to question before you start learning about possible attacks. This system provides smaller datasets that are entirely high-value, as your IT and analytics team does not have to filter out legitimate traffic.
Honeypot security also puts you ahead of the game. While your attackers believe they have made their way into your network, you have diverted their attacks to a system with no value. Your security team is given early warning against new and emerging attacks, even those that do not have known attack signatures.
Making Valuable Use of Honeypot Security
More recently, sophisticated honeypots support the active prevention of attacks. A comprehensive honeypot security solution can redirect opportunistic hackers from real servers to your honeypot, learning about their intentions and following their moves, before ending the incident internally with no harm done.
Using cutting-edge security technology, a honeypot can divert a hacker in real-time, re-routing them away from your actual systems and to a virtualized environment where they can do no harm. Dynamic deception methods generate live environments that adapt to the attackers, identifying their methods without disrupting your data center performance.
You can then use the information you receive from the zero-risk attack to build policies against malicious domains, IP addresses and file hashes within traffic flows, creating an environment of comprehensive breach detection.
It’s important to remember that a high-interaction honeypot without endpoint security could be used as a launch pad for attacks against legitimate data and truly valuable assets. Honeypots are intended to invite attackers, and therefore add risk and complexity to your IT ecosystem. As with any tool, honeypots work best when they are integrated as part of a comprehensive solution for a strong security posture. The best cyber-security choice for your organization will incorporate honeypots as a detection and prevention tool, while utilizing additional powerful security measures to protect your live production environment.
Virtualization and Cloud review comment that while honeypots and other methods of intrusion detection “are usable in a classical environment, they really shine in the kinds of highly automated and orchestrated environments that make use of microsegmentation.”
Honeypot security systems can add a valuable layer of security to your IT systems and give you an incomparable chance to observe hackers in action, and learn from their behavior. You can gather valuable insight on new attack vectors, security weaknesses and malware, using this to better train your staff and defend your network. With the help of micro-segmentation, your honeypot security strategy does not need to leave you open to risk, and can support an advanced security posture for your entire organization.
https://www.guardicore.com/wp-content/uploads/2018/10/file-integrity-monitoring-resize-for-blog.jpg 187 686 Igor Livshitz https://www.guardicore.com/wp-content/uploads/2019/02/guardicore-logo-white-space.png Igor Livshitz2018-10-04 06:48:582019-03-25 18:24:17What is File Integrity Monitoring and Why Do I Need It?
There are two main ways that file integrity monitoring makes a difference, Firstly, once attackers have gained entry to your network, they often make changes to file contents to avoid being detected. By utilizing in-depth detection of every change happening on your network and contextually supporting alerts based on unauthorized policy violations, file integrity monitoring ensures attackers are stopped in their tracks.
File integrity monitoring (FIM) is an internal control that examines files to see the way that they change, establishing the source, details and reasons behind the modifications made and alerting security if the changes are unauthorized. It is an essential component of a healthy security posture. File integrity monitoring is also a requirement for compliance, including for PCI-DSS and HIPAA, and it is one of the foremost tools used for breach and malware detection. Networks and configurations are becoming increasingly complex, and file integrity monitoring provides an increased level of confidence that no unauthorized changes are slipping through the cracks.
How Does File Integrity Monitoring Work?
In a dynamic, agile environment, you can expect continuous changes to files and configuration. The trick is to separate between authorized changes due to security, communication, or patch management, and problems like configuration errors or malicious intent that need your immediate attention.
File integrity monitoring uses the process of baseline comparison to make this differentiation. One or more file attributes are stored internally as a baseline, and this is then compared periodically when the file is being checked. Examples of baseline data used could be user credentials, access rights, creation dates, or last known modification dates. In order to ensure the data is not tampered with, the best solutions calculate a known cryptographic checksum, and can then use this against the current state of the file at a later date.
File Integrity Monitoring: Essential for Breach Detection and Prevention
File integrity monitoring is a prerequisite for many compliance regulations. PCI DSS for example mentions this foundational control in two sections of its policy, For GDPR, this kind of monitoring can support five separate articles on the checklist. From HIPAA for health organizations, to NERC-CIP for utility providers, file integrity monitoring is explicitly mentioned to support best practice in preventing unauthorized access or changes to data and files.
Outside of regulatory assessment, although file integrity monitoring can alert you to configuration problems like storage errors or software bugs, it’s most widely used as a powerful tool against malware.
There are two main ways that file integrity monitoring makes a difference, Firstly, once attackers have gained entry to your network, they often make changes to file contents to avoid being detected. By utilizing in-depth detection of every change happening on your network and contextually supporting alerts based on unauthorized policy violations, file integrity monitoring ensures attackers are stopped in their tracks.
Secondly, the monitoring tools give you the visibility to see exactly what changes have been made, by whom, and when. This is the quickest way to detect and limit a breach in real-time, getting the information in front of the right personnel through alerts and notifications before any lateral moves can be made or a full-blown attack is launched.
Incorporating file integrity monitoring as part of a strong security solution can give you even more benefits. Micro-segmentation is an essential tool that goes hand in hand for example. File integrity monitoring can give you the valuable information you need about where the attack is coming from, while micro-segmentation allows you to reduce the attack surface within your data centers altogether, so that even if a breach occurs, no lateral movement is possible. You can create your own strict access and communication policies, making it easier to use your file integrity monitoring policies to see the changes that are authorized and those which are not. As micro-segmentation works in hybrid environments, ‘file’ monitoring becomes the monitoring of your entire infrastructure. This extended perimeter protection can cover anything from servers, workstations and network devices, to VMware, containers, routers and switches, directories, IoT devices and more.
Features to Look for in a File Integrity Monitoring Solution
Of course, file integrity monitoring can vary between security providers. Your choice needs to be integrated as part of a full-service platform that can help to mitigate the breach when it’s detected, rather than just hand-off the responsibility to another security product down the line.
Making sure you find that ideal security solution involves checking the features on offer. There are some must-haves, which include real-time information so you always have an accurate view of your IT environment, and multi-platform availability. Most IT environments now use varied platforms including different Windows and Linux blends.
Another area to consider is how the process of file integrity monitoring seamlessly integrates with other areas of your security posture. One example would be making sure you can compare your change data with other event and log data for easy reporting, allowing you to quickly identify causes and correlative information.
If you’re using a micro-segmentation approach, creating rules is something you’re used to already. You want to look for a file integrity monitoring solution that makes applying rules and configuring them as simple as possible. Preferably, you would have a template that allows you to define the files and services that you want monitored, and which assets or asset labels contain those files. You can then configure how often you want these monitored, and be alerted of incidents as they occur, in real-time.
Lastly, the alerts and notifications themselves will differ between solutions. Your ideal solution is one that provides high level reporting of all the changes throughout the network, and then allows you to drill down for more granular information for each file change, as well as sending information to your email or SIEM (security information and event management) for immediate action.
File Integrity Monitoring with Micro-Segmentation – A Breach Detection Must Have
It’s clear that file integrity monitoring is essential for breach detection, giving you the granular, real-time information on every change to your files, including the who, what, where and when. Alongside a powerful micro-segmentation strategy, you can detect breaches faster, limit the attack area ahead of time, and extend your perimeter to safeguard hybrid and multi-platform environments, giving you the tools to stay one step ahead at all times.
https://www.guardicore.com/wp-content/uploads/2018/09/cost-of-data-breach-resized.jpg 187 686 Yifat Mor https://www.guardicore.com/wp-content/uploads/2019/02/guardicore-logo-white-space.png Yifat Mor2018-09-20 01:15:532019-05-21 23:00:50The Average Cost of a Data Breach, and how Micro-Segmentation can Make a Difference
In the US, the financial cost of a data breach is rising year on year. IBM’s Cost of a Data Breach Report, is independently conducted annually by the Ponemon Institute. This year, the report included data from more than 15 regions, across 17 industries. They interviewed IT, compliance, and data protection experts from 477 companies. As a result, the true average cost of a data breach is more accurate than ever.
Crunching the Numbers: The Average Cost of a Data Breach
According to the study, the average cost of a data breach in 2018 is $3.86 million, which has increased by 6.4% since last year’s report.
While the risk of a data breach is around 1 in 4, not all breaches are created equally. Of course, the more records that are exposed, the more expensive and devastating a breach will be. A single stolen or exposed data record costs a company an average of $148, while 1 million, considered a Mega Breach, will cost $40 million. 50 million may be reserved for the largest enterprises, but this will raise the financial cost to $350 million.
Beyond a Ransom: The Hidden Cost of Data Breach
Although many businesses worry about the rise in ransomware, the cost of a data breach is about much more than any malicious demand from a hacker could be. The true cost can be broken down into dozens of areas, from security upgrades in response to the attack to a drop in your stock price when word of the breach gets out. Research by Comparitech found that companies tend to see a stock price slide of 42% following a breach. Other costly elements of a data breach include Incident investigation, legal and regulatory activity, and even updating customers. These all contribute to the escalating cost when you fail to adequately protect your company against a data breach.
The Ponemon study found that the largest cost comes from customer churn. The US sees the highest cost in the world in terms of lost business due to a data breach, more than two times the average figure, at $4.2 million per incident. Most analysts put this discrepancy down to the nature of commerce in the United States. In the US, there is far more competition and choice, and customer loyalty is both harder to hold onto and almost impossible to retrieve once trust is lost.
Customers also have more awareness of data breaches in the US, as laws dictate they must be informed of any issues as they are uncovered. This kind of reputational damage is devastating, especially in the case of a Mega Breach. In fact, 1/3 of the cost of Mega Breaches can be attributed to lost business.
Of course, there is also the fear that even if you manage to recover from a data breach, the worst is not over. The IBM study found that there is a 27.9% chance of another breach in the following two years after an attack, making your company extremely vulnerable unless you can make considerable changes, and fast.
Preparing Your Business for the Average Cost of a Data Breach
The numbers don’t lie. The speed and impact of data breaches is something to which every company, no matter the size, should be paying attention. There are definitely ways to protect your business and to position yourself responsibly for the worst case scenarios.
According to Verizon, 81% of all breaches exploit identity, often through weak passwords or human error. Malware can piggyback onto a legitimate user to get behind a physical firewall, which is why most IT professionals agree that even next-gen firewalls are insufficient. To limit the potential repercussions of this, all businesses need to be employing a zero-trust model.
With micro-segmentation, perimeters can be created specifically for the protection of sensitive or critical data. This ensures that all networks are considered not trusted. Using a granular approach to limit communications, and tagging workloads themselves with labels and restrictions. Containment of attacks is built into your security from the outset, by limiting the attacker’s freedom of movement and restricting ability for any lateral movement at all. As the financial impact of a data breach rises with the amount of data records stolen, this is a significant weapon to have at your disposal.
Rapid Response Can Limit the Cost of Data Breaches
Efficiency in identifying an incident as well as the speed of the response itself has a huge impact. Rapid response can save money, as well as proving to your customers that you still deserve their trust. According to the IBM report, the average time it took companies to identify the data breach was 197 days. Even once a breach was detected, the average time to contain it was a further 69. When it came to a Mega Breach – it could take an entire year to detect and contain.
With micro-segmentation, the visibility is immediate. All communications are logged, including East-West traffic. This includes private architecture, cloud-based systems, and even hybrid solutions. The best solutions will offer alerts and notifications in case of any unusual behavior, allowing you to stop threats in their tracks, before any damage has been done.
The quicker this happens, the less financial damage will be done. In fact, on average, companies who suffered a breach that managed to contain it within 30 days saved more than $1 million over companies who couldn’t. The larger the breach – the more significant these savings are likely to be.
Ensure You’re Fully Armed Against a Data Breach
The complex nature of most businesses IT systems explains the growing threat of cyber-crime, and the increasing financial cost of lax security holding us all to ransom. Traditional security systems are not enough to ensure adequate protection from a data breach, or rapid detection and response in case the worst happens.
Micro-segmentation offers granular flexible security that adapts to your exact environment, detecting and limiting the force of an attack, and providing the visibility and response tools you need to keep your customers loyal.

Understanding Attack Vectors
An attack vector is the way that an adversary can gain unauthorized access to your network or devices. Over the years, there have been dozens of different attack vectors, many of which have adapted and evolved over time to cause harm or hold companies hostage. Today, networks and organizations are interconnected using both private and public clouds leaving the door ajar for attack vectors that are more sophisticated than ever. What should smart businesses look out for, and how can they protect themselves?
The Evolution of Cyber Attack Vectors
Traditionally, having hardened perimeter security was enough to protect data centers. Layers of security to detect and prevent a breach coming in or out of data centers meant that you could ward off attack vectors to your infrastructure and hardware, which was almost exclusively on-premise.
The Cloud and mobile solutions have changed all of this. The reality for data centers today is keeping data private and secure while running an environment that spans public, private and hybrid clouds. Companies now use a mix of compute resources: Containers, Serverless Functions and VMs. However hackers are not just targeting your compute resources, they are sneaking in via routers and switches, or storage controllers, and sensors. From this vantage point, attackers can then scale their attack, compromising an entire network with lateral movements and connected devices. The MITRE ATT&CK Framework is a great resource to dive deeper on the different initial access attempts¹.
As the way we access the internet changes, cyber attack vectors adapt their own designs right alongside. Assuming that we are plugging all the holes on the IT side is not enough. The human factor has always been a key vulnerability in the security scheme. It has become more prevalent with the advance in end-user technology in recent years. Smartphones are a good example of this. Mobile attack vectors are not something that any organization had to be aware of a decade ago, and now they are an ever-present reality providing an easy gateway into many organizations.
While most people know not to click on dangerous links that arrive via SMS from unknown numbers, and no longer fall prey to email phishing campaigns like unexpected warnings of your bank password being changed, new attack vectors come from unexpected places. The recent Man in the Disk attacks on Android devices are something no one could have anticipated. This malware relies on vulnerabilities in third-party application storage protocols that are not regulated by sandbox restrictions through Android². This careless use of external storage can lead to potential malicious code injection, or the silent installation of unrequested apps to the user’s device. From there, the journey of an attacker to leverage this access to a deeper data center one is very short.
As technology evolves, there are more ways than ever for bad actors to launch attacks. Smart devices and Cloud-solutions only serve to increase the number of platforms which can be used for malicious intent.
Which Attack Vectors Are the Biggest Threats Today?
Email and phishing schemes have been the attack vectors of choice for a large amount of malicious attacks over the past few years. However, as simple attacks are becoming more recognizable, more complex threats are increasingly in vogue. Worryingly, the trend in malware is a movement away from reliance on human error, to clever attack vectors that can strike without any conscious act by the user whatsoever³. Man-in-the-Disk was just one example of this.
Administrator access could be the weak link when it comes to keeping your data centers safe overall. By accessing admin privileges, adversaries have access to the most valuable information you store, and can therefore cause the most harm. It’s important to think about the way your business works in a crisis when you’re planning preventive security measures. Used in an emergency, local authentication options are often not logged in the same way as your admins usual activity, and the credentials may even be shared across workloads and hosts for the sake of ease of use.
As well as smarter attack vectors, the growth in threats such as file-less attacks show that attackers are getting better at learning how to cover their tracks. 77% of cyber-crime in the US last year used a form of file-less attack⁴. Research shows that this type of malware is ten times as likely to succeed as traditional file based attacks, and helps attackers stay well beneath the radar.
AI is also an area that is likely to be compromised in the near future, with many companies creating chatbots and machine learning tools as the customer-facing representative of their websites and apps. As virtual assistants are built by humans, they are subject to the same gaps that human knowledge has. Studies are beginning to show that AI has problems with hallucinations and recognition⁵. Let loose on customer data and processes, it’s easy to see how advanced malware may slip through the cracks.
More than ever, in preparation for the next stage of intelligent malware, companies need to secure their data centers effectively against the latest attack vectors.
How Can Businesses Protect Themselves from Cyber Attack Vectors?
Keeping your IT environment safe from the latest attack vectors means being able to detect threats faster, and with better intelligence.
This starts with visibility. Being able to identify application flows across your entire infrastructure means that you have granular visibility across your whole IT stack. Dynamic deception tactics automatically trap attackers, even when the end-user isn’t aware of what is going on under the surface. Reputation analysis instantly uncovers anything suspicious or out of the ordinary, from unexpected IP addresses and domain names to file hashes within application flows. Even new attack vectors are isolated in real-time, with mitigation recommendations so that incident response is streamlined.
Ring-fencing, the separation of one specific application from the rest of the IT landscape is one way that companies are limiting the reach of the latest attack vectors from their most sensitive data or valuable assets. This and other kinds of micro-segmentation allow your business to truly limit the attack surface of any potential breach.
There are a number of benefits to this. Regardless of operating system limitations, communication policy can be enforced at the layer 4 transport level as well as the Layer 7 process level. By segmenting your flows by the principle of least privilege, even if a breach occurs, you ensure that it is quickly isolated, and attackers are unable to make lateral moves or scale their intrusion any further. When micro-segmentation is enforced alongside breach detection and threat resolution, even new attack vectors can quickly become a known quantity, and are unable to pose real danger.
Staying Safe Against Future Cyber-Attack Vectors
The way that data is stored and transferred is dynamic in and of itself. Our methods and processes are always changing as the capabilities of the cloud and the hybrid nature of our IT environments continue to grow. In direct response, attack vectors will never stay the same for long, and hackers will always have new tricks up their sleeve to compromise the latest solutions and catch us unaware. As well as current attack vectors that take advantage of IoT devices and no-fault infiltration, predictions for the future include AI-driven malware and an increase in file-less malware attacks, allowing hackers to hide their activities from detection.
The only solution is true visibility of all your applications and workflows. Using this mapping alongside segmentation policy that controls communication flows can restrict attackers in their tracks at the smallest sign of an anomaly. Even against new or unknown attack-vectors, these tools enable true threat resolution that can protect your entire infrastructure in real-time.
