Cybersecurity Mesh

Gartner defines cybersecurity mesh architecture (CSMA) as “a composable and scalable approach to extending security controls, even to widely distributed assets. Its flexibility is especially suitable for increasingly modular approaches consistent with hybrid multicloud architectures. CSMA enables a more composable, flexible, and resilient security ecosystem. Rather than every security tool running in a silo, a cybersecurity mesh enables tools to interoperate through several supportive layers, such as consolidated policy management, security intelligence and identity fabric.”

Cyber Security Mesh Architecture

CSMA has four foundational layers to configure and manage distinct security services.

1. Security analytics and intelligence: Collecting and analysing security data from security tools with the help of a Security Information and Event Management (SIEM) tool will provide real-time threat notifications.
2. Distributed identity fabric: Decentralized directory services, which are essential to a zero-trust paradigm, are prepared and provided to the security system. These include user entitlement management, adaptive access, identity proofing, and decentralized systems.
3. Consolidated policy and posture management: Configuring individual security tools by translating a central policy into the native configuration constructs to ensure consistent and standardized security policies among the security systems.

The Layers of Cybersecurity Mesh

Adopting a cybersecurity mesh strategy has distinct advantages, specifically scalability, composability, and interoperability. For new developments, this strategy changes the approach to designing and building the network infrastructure. For existing networks, evolving to a new strategy may mean significant adjustments to the infrastructure at first, but the benefits justify the cost. 

1. Security Analytics and Intelligence

Centralized administration means that vast amounts of data can be collected, consolidated, and analyzed in real-time at a central location. This improves your risk analysis capabilities, threat response time, and mitigation of attacks. CSMA “combines the data and lessons from other security tools, and provides analyses of threats and triggers appropriate responses.”

2. Distributed Identity Fabric

This layer “provides capabilities such as directory services, adaptive access, decentralized identity management, identity proofing and entitlement management.”

3. Consolidated Policy and Posture Management

CSMA “can translate a central policy into the native configuration constructs of individual security tools or, as a more advanced alternative, provide dynamic runtime authorization services,” ensuring IT teams can more effectively identify compliance risks and misconfiguration issues. 

Cybersecurity Mesh Principles

A Zero Trust Architecture approach verifies and authenticates, regardless of the network location or user/device identity.

A Decentralized approach ensures security controls are distributed across the network as opposed to being centralized at one location. This makes it possible for a more robust and flexible security posture.

An Interoperability aspect encourages communication and cooperation among various security platforms and solutions, enabling the sharing and integration of security data with ease.

Why Enterprises Need Cybersecurity Mesh

Cybersecurity mesh is the most practical and adaptable approach for dealing with these threats in an enterprise-level organization. It extends security across your entire architecture, making it possible to secure all systems and points of access with a single, unified set of technologies.
