An attack vector is the way that an adversary can gain unauthorized access to your network or devices. What should smart businesses look out for, and how can they protect themselves against these increasingly sophisticated cyber attacks and threats?

Micro-segmentation as we know it today has gone through several stages in the last few years, moving from a rising trend for securing software-defined data centers to a full-blown cyber security technology and a top priority on the agenda of nearly every CISO. In this blog we examine the GuardiCore journey to becoming the best micro-segmentation solution.

While IT security teams often devote significant attention to perimeter protection, east-west traffic is outgrowing north-south traffic in both volume and strategic importance due to changes in data center scaling approaches, new big data analysis needs, and growing use of cloud services with a less defined perimeter. It’s more important than ever for IT security teams to develop their capabilities to prevent lateral movement in these types of environments. Read more about lateral movement security.

Any business that works with payment data recognizes the challenges involved with sustainable compliance. PCI regulations change as the industry learns more about security and as wider threats evolve. Learn how you can bring your organization on board for sustainable compliance, using the right security tools and correctly managing an ongoing project.

Micro-segmentation is an emerging security best practice that offers a number of advantages over more established approaches like network segmentation and application segmentation. The added granularity that micro-segmentation offers is essential at a time when many organizations are adopting cloud services and new deployment options like containers that make traditional perimeter security less relevant.

The best way for organizations to get started with micro-segmentation is to identify the methods that best align with their security and policy objectives, start with focused policies, and gradually layer additional micro-segmentation techniques over time through step-by-step iteration.

One of the major benefits of micro-segmentation is that it provides shared visibility into the assets and activities in an environment without slowing development and innovation. Implementing micro-segmentation greatly reduces the attack surface in environments with a diverse set of deployment models and a high rate of change.

Using VLANs for segmentation has a nice advantage - it requires no new tools and you can use your existing networking infrastructure. But the reality is that there are hidden costs to this approach which make it expensive (in fact, very expensive). Let's take a look at some of the often unknown costs associated with VLAN segmentation.

Last week, the GuardiCore team participated at the 2018 Gartner Security and Risk Management Summit in National Harbor, MD. This year we were honored to be named as a Cool Vendor in the June 2018 Gartner, “Cool Vendors in Security for Midsize Enterprises” report.
