In this blog series, we will explore the concept of micro segmentation, it’s advantages, and the hurdles faced by traditional segmentation methods. So, fasten your seatbelts as we dive into the world of network defense and its crucial inner workings!
What is micro segmentation?
Micro segmentation is a method of defending the interior of the data center network, rather than just the perimeter. Think of the network as a castle. There are guards outside the castle to keep people from getting in. If someone is able to infiltrate the defense, it’s important to have guards on the inside to further protect the castle. This is how micro segmentation works in your network.
Micro segmentation can isolate workloads with policy by gaining visibility and control of the network traffic between workloads. This allows your organization to implement a Zero Trust approach on individual workloads to contain unauthorized lateral movement.
What are the benefits of micro segmentation?
Improved breach containment, which gives your security team the ability to monitor network traffic against predefined policies as well as shorten response times to incidents. Visibility into the complete network environment without slowing development or innovation. Application developers can integrate security policy definition early in the development cycle and ensure that neither application deployments nor updates create new attack vectors. Stronger regulatory compliance, so regulatory officers can create policies that isolate systems subject to regulations from the rest of the infrastructure.
What are the challenges with traditional segmentation?
The most common challenges include:
- Traffic visibility is limited to North-South firewalls which are too expensive to segment and inspect all East-West traffic.
- Host-based firewalls installed on individual computers are unmanageable at scale and are easily disabled in attacks.
- The burden of managing security policy on an individual VM basis in a dynamic environment is too high.
Tego’s Professional Services team is skilled at helping organizations with micro segmentation. In our next video, we’ll discuss the use cases and myths associated with micro segmentation.
Conclusion: In this first installment, we’ve uncovered the fundamentals of micro segmentation, its benefits, and the drawbacks of traditional segmentation methods. By fortifying your network’s interior, micro segmentation offers unparalleled protection against intrusions and unauthorized lateral movements. Stay tuned for the 2nd part of this blog post, where we’ll dive deeper into this topic.
Remember, the security of your data center is not just about building strong perimeters; it’s about having guards inside to protect the castle. Join us in our quest to unlock the full potential of micro segmentation and revolutionize the way we defend our networks.
