Microsegmentation: Reducing Attack Surface in Large Networks

Microsegmentation is an adaptive and proactive defense mechanism that protects a network by dividing it into smaller, isolated segments based on workloads or applications.

In contrast with traditional segmentation, microsegmentation uses software-defined policies to control and monitor communication between workloads. Through this fine-grained control, enterprises can enforce security policies based on application behavior, user roles or data sensitivity, regardless of the physical or virtual infrastructure.

Enterprise Security Benefits of Microsegmentation

Enterprises benefit from microsegmentation because it increases network security, visibility and compliance. In particular, it provides the following enterprise security benefits:

  • Reduced attack surface: Using microsegmentation, enterprises can limit lateral network movement by isolating segments and enforcing strict communication policies. Even if attackers compromise one network segment, they cannot access other segments, reducing the scope and impact of breaches.
  • Improved threat containment: Microsegmentation isolates threats and prevents them from spreading to critical systems by segmenting workloads and applications. This way, the impact of malware, ransomware and other attacks is minimized.
  • Enhanced visibility: Microsegmentation enables detailed analysis of how workloads, applications and users interact. This visibility helps identify unusual patterns or anomalies, enabling faster detection and response to potential threats.
  • Granular policy control: With microsegmentation, security policies can be tailored based on factors such as application behavior, user identity or workload location. With this fine-grained control, only authorized interactions occur, reducing the risk of unauthorized access.
  • Support for zero trust architecture: Through microsegmentation, the zero-trust security model can be enforced by ensuring that only authenticated and authorized entities can communicate.
  • Improved compliance: Microsegmentation enables organizations to meet data protection regulations, such as the General Data Protection Regulation (GDPR), the Health Insurance Portability and Accountability Act (HIPAA) and the Payment Card Industry Data Security Standard. Access to sensitive systems is tightly controlled and auditable.
  • Adaptability to dynamic environments: Modern, dynamic IT environments, such as multi-cloud, hybrid cloud and containerized applications, benefit from microsegmentation by ensuring consistent policy enforcement regardless of the infrastructure or workload location.
  • Simplified security management: In complex and distributed environments, microsegmentation simplifies security policy enforcement and management with centralized control and automation.
  • Cost efficiency: While it requires an initial investment, microsegmentation reduces the cost of potential data breaches by limiting their impact. It also decreases reliance on physical hardware for network segmentation, leveraging software-defined solutions instead.
  • Future-proofing against evolving threats: As threats become more sophisticated, microsegmentation provides a flexible security approach, ensuring networks remain secure against new types of attacks.
