Introduction

This article is part of a series on implementing BIG-IP SSL Orchestrator. It includes high availability and central management with BIG-IQ.

Implementing SSL/TLS Decryption is not a trivial task. There are many factors to keep in mind and account for, from the network topology and insertion point, to SSL/TLS keyrings, certificates, ciphersuites and on and on. This article focuses on configuring a 3rd party, Explicit Proxy security device and everything you need to know about it.

This article covers the configuration of Cisco Web Security Appliance (WSA) running version 11.8.

Please forgive me for using SSL and TLS interchangeably in this article.

A common Cisco WSA deployment mode is as an Explicit Proxy. The WSA proxy is completely transparent to the user but the BIG-IP will connect to it as an Explicit Proxy.

The default settings for Cisco WSA will work with SSL Orchestrator. Keep in mind that:

1)   By default WSA accepts connections on ports 80 & 3128. If you changed this you will have to specify the correct port when configuring SSLO.

2)   It is assumed you are using WSA security features like URL categorization, Anti-Malware, Reputation filtering, etc. 

3)   It is recommended to use separate ethernet ports for Management and Data, similar to the image below.
