BlueCoat Proxy – Web URL Category Review / Best Practices

January 18, 2014 by ryanhorst

This page will attempt to assist you in building a Web URL Category review process, as well as provide best practice recommendations from BlueCoat and my own personal experience with BlueCoat. BlueCoat does not update their Web URL Categories very often, but it does happen about once every 12-18 months. In earlier times, they were not very helpful about this and normally only included a single email to subscribed users (a very manual process - it is not created for you when you purchase a … [Read more...]

January 18, 2014 by ryanhorst

Often times when I come to a company it is to bolster, revamp or help them re-evaluate their web security posture, with a focus on data exfiltration investigations and outbound web proxy is a great place to start. 90% of the time, when I finally gain access to the management console, I am greeted by an appalling SGOS 5.4 or 5.5 header across the top... This is sad because those versions of code were released 4-5 years ago, and have since been replaced by a much much richer SGOS code, with many … [Read more...]

Web Proxy And The Need For SSL Decryption

January 18, 2014 by ryanhorst

Most organizations will deploy a Web Proxy solution, but not intercept HTTPS traffic to do SSL decryption and inspection. This may be done for various reasons * Not yet having a PKI infrastructure to manage the SSL browser certificates * Perhaps the AD/GPO team doesn’t want to manage SSL certificate on the user PC * Security teams may be weary about man-in-the-middle issues * Maybe SSL interception just wasn’t a concern at the time. Without doing SSL decryption and inspection our … [Read more...]

BlueCoat Proxy – Log Injection For Rule Tracking

January 18, 2014 by ryanhorst

Unfortunately BlueCoat doesn't have a nice and fancy log tracker type utility like CheckPoint has in Smart Tracker, so the rules do not have numbers.  However, you can work around this by using some log injection smoke and mirror tricks. There are a few unused (or not very often used) log variables that can be used in conjunction with a specific action on a rule, that when matched, will create a log line with a piece of text of your choosing. … [Read more...]

Blue Coat ProxySG – ICAP, deferred scanning, and data trickling

January 4, 2012 by ryanhorst

Recently I was digging into a BlueCoat ProxySG / ProxyAV setup for ICAP and noticed some things that had room for improvement. Not a major overhaul, but some things that were missed from the best practices guide that just so happened to be causing a bit of an issue. Below is part of the small case study I completed to explain the options and differences between them, as well as my recommendations to management on how to proceed. Scope: At least once a month, if not more, I would hear … [Read more...]
