Why good microsegmentation is the key to zero trust

It's not just the violation; it is the lateral movement that distributes malicious code to destroy IT infrastructures, making zero trust a priority. Many CISOs and business leaders have recently been in a firefight as they attempt to increase the resilience of their technology stacks and infrastructure while containing breaches, malware, and access credential abuse. .

Unfortunately, rapidly expanding attack surfaces, unprotected endpoints, and fragmented security systems make resiliency an elusive goal.

The mindset that attempted breaches are inevitable leads to more zero-trust planning, including micro-segmentation. At its core, zero trust is defined assuming that all entities are untrusted by default, least privilege access is enforced on every resource and identity – and comprehensive security oversight is implemented.

Microsegmentation is at the heart of zero trust

The goal of network microsegmentation is to separate and isolate defined segments in a corporate network, reducing the number of attack surfaces to limit lateral movement. As one of the core elements of zero trust based on NIST's zero rust framework, microsegmentation is valuable for securing IT infrastructure despite its weaknesses in protecting private networks.

register here IT and security teams need a breach mindset

It is critical to assume that external networks are a viable, hostile, and determined threat to breach the infrastructure and move laterally through the infrastructure. With a supposed breach mindset, IT and security teams can meet the challenges of eradicating as much implicit trust as possible from a technology stack.

Identity management contributes to implicit trust in technology stacks,

Replacing implicit trust with adaptive, explicit trust is a goal that many organizations set when defining a zero trust strategy. Human and machine identities are the security perimeters of any zero-trust network, and identity management must provide least-privileged access at everyone's scale.

Microsegmentation becomes difficult to define which identities belong to each segment. Since almost every business has a large percentage of their workload in the cloud, they must encrypt all data at rest on each public cloud platform using different customer-controlled keys. Securing data-at-rest is a critical requirement for nearly every enterprise pursuing a zero-trust strategy today, all the more urgent as more organizations migrate their workloads to the cloud. p> Microsegmentation policies must scale on-premises and in the cloud

Microsegmentation should extend to on-premises, cloud, and hybrid clouds to reduce the risk of cyberattackers exploiting misconfigurations to gain access. It is also essential to...
