Additionally, there are multiple ways of network segmentation. Among them is network segmentation that relies on VLANs or subnets using IP addresses. Also, there is Firewall segmentation where firewalls get deployed inside the network to formulate internal zones and partition functional areas from each other to restrain attack surfaces.
Further, there is segmentation with SDN that relies on greater network segmentation and programmability through centralized controllers.
Micro-segmentation is a kind of segmentation enforced using the host workloads contrary to subnets or firewalls. The approach utilizes whitelist models that obstructs all traffic excluding just permitted. It utilizes workload telemetry to create a map of cloud and on-premises compute environments. The map helps visualize the data that needs to be protected and, further, formulate an automated policy for segmentation.
What is more distinctive is that this approach can implement segmentation up to the process level, with different levels of granularity. The granular approach helps organizations build fences to guarantee authentic access and data flows across the organization applications. Additionally, it identifies and sets rules governing key workloads, applications, and servers.
Micro-segmentation is a major pillar of zero-trust security and is considered one of the most powerful techniques that protect against breaches.
Gaining visibility into the application layer illuminates the demeanor of applications, workloads, and flows to predict risk areas and create effective strategy of addressing the threats. To explain, micro-segmentation maps out the application dependency to provide real-time visibility based on Illumination, a real-time application dependency map.
Thanks to micro-segmentation, organizations can create micro-perimeters surrounding particular assets. These micro-perimeters help decouple the attack surface to deliver granular control needed for breach containment.
With micro-segmentation, you can orchestrate communications between applications, hypervisors, or containers, whether on-premises or in the public, private, or hybrid clouds. In the meantime, Illumio allows organizations to apply and test policies first to ensure that implementing segmentation will not break applications or impact workloads.
Illumio enables organizations to dissociate segmentation from the underlying network to define policies on the basis of the language that IT uses. Illumio’s labels are readable by humans to make policy creation easier than the traditional approaches of network segmentation such as VLANs and SDNs.
Applying Illumio’s micro-segmentation will enable you to meet compliance requirements that include PCI DSS, HIPAA, and SOX with no need to re-architect your network. Therefore, you will easily segment and separate protected systems and encrypt communications across applications.
Vulnerabilities are usually a source of risk for companies. For this reason, Illumio integrates companies’ applications and software with a third-party vulnerability scan to help identify the potential pathways of malicious actors.
All network segmentation approaches do not suffice due to the legacy methodologies they implement. Micro-segmentation currently plays a crucial role in achieving zero-trust security. Illumio delivers micro-segmentation that is based on granular approaches to build fences down to the application level and guarantee appropriate access and risk mitigation.
