Cybersecurity Mesh: How It Helps in the New Era of Protection

Cybersecurity threats have multiplied today. Remote work, IoT devices, virtual networks, and edge computing present various security challenges. And your current security architecture may not successfully address these issues. Enters Cybersecurity Mesh Architecture, a new approach to strengthen your organization’s security posture.

What is Cybersecurity Mesh Architecture, what benefits does it offer, and how can you implement it? Let’s find out.

Cybersecurity Mesh Architecture

Cybersecurity Mesh Architecture (CSMA) is a security framework proposed by Gartner to help organizations take a composable, flexible, and scalable approach to secure their IT infrastructures from bad actors.

Cybersecurity mesh architecture works by adopting distributed, composable security controls by centralizing data and control to achieve more collaboration between the security tools you implement.

Consequently, organizations increase their capabilities to detect security incidents, improve their responses to threats, and have a consistent policy, posture, and playbook management.

Moreover, CSMA enables companies to have adaptive and granular access control to protect their IT assets better.

Foundational Layers of CSMA

Cybersecurity Mesh Architecture (CSMA) offers a security framework that’s scalable, interoperable, and composable, allowing diverse security controls and tools to work together seamlessly.

The four foundational layers of cybersecurity mesh architecture define core security goals and functions.

#1. Security Analytics and Intelligence

The first layer of cybersecurity mesh architecture, security analytics and intelligence, collects and analyzes data from different security solutions in an organization.

CSMA has centralized administration, so organizations can collect, aggregate, and analyze vast data from a central place.

Companies’s security information and event management (SIEM) can analyze this data and trigger appropriate responses to mitigate threats.

#2. Distributed Identity Fabric

The distributed identity fabric layer works on decentralized identity management, directory services, adaptive access, identity proofing, and entitlement management.

These tools tell who can access data and where data should be used and modified while helping your security teams differentiate between malicious actors and genuine users.

In a nutshell, this layer focuses on providing identity and access management crucial to zero-trust security.

#3. Consolidated Policy and Posture Management

If you have to enforce your central security policy across different environments, you have to translate your policy into configurations and rules for each environment or security tool.

The consolidated policy and posture management layer breaks down your policy into rules and configuration settings required for a specific security tool or environment. Additionally, it can offer dynamic runtime authorization services.

#4. Consolidated Dashboards

You must switch between different dashboards if your organization has implemented disconnected security solutions. Doing so can impede security operations.

This layer offers a single-pane dashboard to view and manage your organization’s security ecosystem.

Consequently, your security team can detect, investigate, and address security incidents more effectively.

Why Organizations Need CSMA

98% of big companies use or plan to use at least two cloud infrastructures, and 31% already use four or more cloud infrastructures. 

That said, organizations today cannot function properly without having resources outside their well-guarded premises. 

Devices they employ, from IoT tools to WAN, operate within their physical premises and outside.

Consequently, organizations should find ways to extend security controls to devices and tools beyond their physical locations. Doing so is required to protect organizations’ networks and devices from different types of ransomware attacks, distributed denial-of-service (DDoS) attacks, phishing attacks, and various other security threats. 

Cybersecurity mesh can help your organization tackle a range of attacks. It allows your security team to manage visible and hidden cloud threats. This method is ideal for safeguarding scattered digital IT assets residing on the cloud and premises. 

Implementing cybersecurity mesh architecture ensures that security policies and security practices are enforced for each security tool and environment your company uses. 

All security solutions in your organization will cooperate with each other to provide your organization with superior threat intelligence & response technology.

With a single dashboard, your cybersecurity professionals can view the entire security ecosystem of your organization. 

Key Features of Cybersecurity Mesh

The following are the key features of cybersecurity mesh:
