Deploying GigaSECURE Inline SSL Solution using Flexible Inline (6.2)


In an enterprise network, one of the key challenges for a security tool is to decrypt and inspect SSL/TLS encrypted traffic. The GigaSECURE Inline SSL solution can be deployed to decrypt and forward the same decrypted traffic to one or more tools (inline or out-of-band). This solution also enables taking a copy of traffic before and after a security tool inspection and is managed by GigaVUE-FM which provides a single pane of glass for deploying, managing, and troubleshooting the solution. This solution can be deployed to:

  • Decrypt the traffic destined for internal servers (inbound).
  • Decrypt the traffic destined for the Internet (outbound).
  • Feed copies of the decrypted traffic to out-of-band tools.

 This Gigamon Validated Design illustrates deploying the GigaSECURE Inline SSL solution to:

  • Decrypt hosted web applications (inbound mode).
  • Enable inspection by an inline tool that cannot process Q-in-Q traffic (non-shared or tag-less mode).
  • Decrypt both inbound and outbound traffic.
  • Copy the decrypted traffic post inspection of Inline tools.

Design Overview

Consider the following scenarios wherein:

  • A Web Application Firewall (WAF) is deployed to inspect traffic destined to/from hosted web applications (Figure 1).
  • An Intrusion Prevention System (IPS) and WAF are deployed to inspect outbound and inbound Internet traffic, and SIEM is deployed to monitor the decrypted traffic (Figure 2). Assume, WAF cannot handle Q-in-Q traffic in this case.
