Long gone are the days when enterprises operated independently and in silos. Today, enterprises operate in a hyperconnected mesh environment with various data touchpoints where cybersecurity is no longer an option but a critical business requirement.
As businesses migrate to the cloud and integrate with third-party ecosystems, they open avenues for unauthorized individuals to gain unauthorized access to a business’s centralized data architecture. An increasing number of cyberattacks further expands the attack surface, making security a complicated concern as threats become sophisticated.
What’s astonishing is that most businesses still leverage and trust a single centralized security firewall to secure everything across their various touchpoints. That worked when data sat in a single place. Today, data travels across the digital landscape and relying on a single source is like ignoring other entry points.
This is where a cybersecurity mesh is most effective, as it distributes policies and security controls across all environments, whether digital, on-premises, or the cloud. It’s a modern approach that doesn’t rely on a single, centralized security perimeter and secures each access point on its own and linking each protection together.
Let's understand what a cybersecurity mesh really is, why enterprises need a cybersecurity mesh, its principles, benefits, and how to implement a cybersecurity mesh architecture.
What is Cybersecurity Mesh?
Gartner defines cybersecurity mesh or cybersecurity mesh architecture (CSMA) as a collaborative ecosystem of tools and controls to secure a modern, distributed enterprise.
Cybersecurity mesh builds on a strategy of integrating composable, distributed security tools by centralizing the data and control plane to achieve more effective collaboration between tools. It provides flexibility and scalability, making it easier to secure complex IT environments. It works in four distinct ways:
- First, you discover every user, device and service,
- Second, you assess identity and device health before letting them in,
- Third, you enforce rules at the closest point,
- Fourth, you share information instantly, so threats are identified quickly.
Consequently, a well-deployed cybersecurity mesh results in enhanced capabilities for detection, more efficient breach incident responses, minimized consistent policy, posture, and playbook management, and more adaptive and granular access control, all of which lead to an improved cybersecurity posture.
Why Enterprises Need Cybersecurity Mesh
Legacy perimeter-based cybersecurity practices no longer cater to today’s hyperscale, evolving climate that is spread across various distributed environments. From one cloud to another, to remote work and interconnected devices, cybersecurity mesh is core to modern-day businesses handling massive volumes of data.
Here are the top 5 reasons why enterprises need cybersecurity mesh:
1. Perimeter less environment
Enterprises today operate in an ever-expanding threat surface with critical assets housed across cloud native platforms, SaaS applications, remote endpoints, and third-party networks. As cybersecurity incidents escalate, a single vulnerability within a centralized security perimeter can exploit core business operations.
Cybersecurity mesh assigns individual security controls for each access point.
2. Remote work expands the attack surface
Individuals are no longer confined to a centralized, restricted, security-controlled environment but rather operate from outside corporate controls.
Cybersecurity mesh helps enforce consistent security regardless of an individual's location.
3. Unified security controls across complex multi-cloud environments
Most enterprises leverage several cloud services, third-party vendors with overlapping controls, along with on-prem systems, each with different security controls and policies. This results in fragmented controls that increase policy gaps, blind spots, inconsistent policies, and slower response times, all of which escalate vulnerabilities.
Cybersecurity mesh enables enterprises to embed a unified security model across all environments, reducing policy gaps, improving integration and coordination between tools, so security works as one system.
4. Improved response time and stronger resilience
When controls are distributed, there’s a lack of communication and coordination, resulting in delayed response time and poor security posture.
Cybersecurity mesh enables enterprises to stay connected in a unified manner, with early threat detection and remediation, minimizing the blast radius and downtime.
5. Enables zero trust and centralizes policy
Organizations that don’t utilize the zero-trust model can now leverage it to verify each access request independently. Additionally, a unified security policy can apply to all environments, ensuring consistency across the board.
Cybersecurity mesh forms the basis for a zero-trust model deployment as well as the ability to manage security policies from a single point.
Principles of Cybersecurity Mesh
At its core, cybersecurity mesh focuses on:
1. Assigning security identity
The mesh philosophy focuses on identifying who or what is requesting access to critical business services. This means identifying the authorized user and device to protect assets.
2. Distributed security enforcement
Security controls are distributed to individual services such as data applications, endpoints, and cloud networks rather than relying on a single centralized security perimeter.
3. Unified policy and governance
Centralized policy and governance ensure consistent policies are enforced across all touchpoints. This helps in demonstrating regulatory compliance, ensuring control and transparency of all business operations.
4. Visibility across the mesh
Mesh security relies on solid telemetry and monitoring across various endpoints. This enables faster detection and response.
5. Cyber resilient infrastructure
Cybersecurity mesh builds a cyber-resilient architecture to reduce the threat surface. The mesh security ensures breach incidents are contained, ensuring no operational disruptions.
Use Cases of Cybersecurity Mesh
Cybersecurity mesh can be leveraged for various purposes. Most notable include:
1. Securing remote work infrastructure and cloud environments
As individuals access the business’s internal network and systems from multiple devices across the globe, cybersecurity mesh protects the network traffic via uniform identity-based access controls. Additionally, businesses that utilize on-premises, AWS, Azure, and GCP environments can implement consistent security guidelines while enabling each environment to function independently. This results in a secure network infrastructure as well as improved cloud governance.
2. Zero-trust access and third-party restrictions
Enterprises can adopt a zero-trust model where only authorized users can access services they are authorized to, instead of having broad access to the entire corporate network. Additionally, third parties can be given restricted access to services that they require for operations, minimizing exposure to internal networks and limiting the attack surface.
3. Swift threat detection and response
As businesses operate under a uniform security posture, it enables swift threat detection and automated, coordinated responses, assisting in regulatory compliance and incident containment.
