Segmenting critical applications is nothing new. We’ve long since established the benefits of isolating sensitive data or essential assets in the enterprise data center, preventing potential breaches from escalating, and stopping lateral movement in its tracks. User Identity Access Management is the next essential layer of control, establishing with fine-grained policy exactly which users can access various applications in the first place, and how.
Here are our top three use cases, all of which are revolutionary for today’s enterprise data center.
Control User Access Anywhere
Many enterprises networks currently have broad permissions to business-critical systems, dangerously coarse controls that can be taken advantage of by attackers, or even manipulated with the help of human error. Not only is this bad practice for any enterprise security posture, but it also makes it increasingly difficult for organizations to remain compliant with the latest regulatory mandates.
In contrast, strong user access management policies allow specific users to be either given access or denied entry, with granular options such as permissions over specific servers, ports and processes.
Even in cases where your organization started out with a network design that allowed all users equal access, user access can be segmented to only the applications, servers and processes to which each individual user or group is entitled. Not only will your organization keep the infrastructure of a single data center, there will be no physical changes, downtime, or additional overhead as there would be with network segmentation projects, and you will be massively simplifying the road to compliance. Take PCI-DSS for example. With strong access management, you can ensure that only those users who are allowed to view cardholder data can physically access your CDE (Cardholder Data Environment).
Just as Guardicore Centra’s segmentation follows the workload rather than any particular underlying infrastructure, our User Identity Access Management follows the individual user, enforcing user governance across any environment, from legacy and bare-metal, physical desktops and laptops, to VDI and hybrid cloud platforms.
Manage Multiple Users, Even When Logged in at the Same Time to the Same System
Think about users who are connected to the same servers at the same time, but who have different access requirements. Perhaps one employee works for HR, and needs access to sensitive personnel files stored in HR management servers, while another works for the Finance team, and is working on an accounting application. They are both administrators, and are working within the same data center.
Without User Identity Access Management policies, the traditional way to secure their access would be with multiple jumpboxes, setting up one for each, with its own network connectivity. This gets expensive and complicated, fast.
A smart access management tool removes the complexity, and streamlines the route to secure user access, even for simultaneous logins to the same server. Each admin can connect from the same jumpbox, at the same time, and yet only have access to their own application, and be blocked from any applications outside of their purview.
Handle Third Party or Administrators Access
It’s more important than ever to manage access for third-party vendors and partners, who may be connected to your network through SaaS, IoT devices, or as contractors working on your own systems. Third-party access management needs to be able to seamlessly handle and define user groups based on these examples and more. Traditional solutions that are based on IP addresses are complex to manage, especially when multiple users are logging on simultaneously to the same server. By using policy creation based on user-identity rather than IP, each user group can have its own policies defined for entry, giving specific access to every group or even individual user, and blocking them from moving any further.
As there is no centralized firewall needed, and access is controlled at the endpoint, your organization can enforce control of users between workloads, even within the same segmented section on the network. Policies take effect immediately, for both new and active sessions, allowing you to act quickly and incisively in case of a security gap.
Solving Three Problems with One Tool
In conjunction with the benefits of application segmentation, User Identity Access is an obvious step to enhance your data center security. Not only can you keep critical assets away from an attack, you can now enforce exactly who should be accessing these applications in the first place, wherever they reside.
