Lists common scenarios where service chaining provides network security and compliance benefits.
Service insertion use cases demonstrate how traffic can be directed through security services like firewalls to enhance network protection, ensure inter-VPN security, and meet regulatory compliance requirements.
-
Service chaining can be used when traffic from a less secure region of a network should pass through a firewall to ensure that it has not been tampered with.
-
Service chaining can be used in a network that consists of multiple VPNs, where each represents a different function or organization, to ensure that traffic between VPNs flows through a firewall. For example, in a campus, interdepartmental traffic might go through a firewall, while intradepartmental traffic might be routed directly.
-
Service chaining can be used to ensure regulatory compliance, such as Payment Card Industry Data Security Standard (PCI DSS), where PCI traffic should flow through firewalls in a centralized data center or regional hub.
