My Engineering Years: this post is from my early hands-on infrastructure days, kept for reference. See the rest of this era. After installing the FireEye app for Spunk and having some issues with it, the app was uninstalled, which left a gap that needed to be filled. So off I went into Splunk land to see if I could scrounge together some decent "dashboard" worthy search queries that could help display important information. Below are a collection of the search queries I have built thus far. It … [Read more...]
FireEye Role Based Access Control (RBAC)
My Engineering Years: this post is from my early hands-on infrastructure days, kept for reference. See the rest of this era. Regarding role based access control and Active Directory integration with FireEye back in FEOS versions 7.0.x (webmps), 6.3.2 (emailmps) and 6.4.1 (CMS), we only had the ability to map a single Active Directory group to a single FireEye "role". And most enterprises would probably have mapped that single group to the Admin role. Well..... Fast >> Forward >> … [Read more...]

BlueCoat Proxy – Web URL Category Review / Best Practices
My Engineering Years: this post is from my early hands-on infrastructure days, kept for reference. See the rest of this era. 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 … [Read more...]
Word To Enterprises… Update Your Security Kit Regularly
My Engineering Years: this post is from my early hands-on infrastructure days, kept for reference. See the rest of this era. 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 … [Read more...]
Web Proxy And The Need For SSL Decryption
My Engineering Years: this post is from my early hands-on infrastructure days, kept for reference. See the rest of this era. 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 … [Read more...]
BlueCoat Proxy – Log Injection For Rule Tracking
My Engineering Years: this post is from my early hands-on infrastructure days, kept for reference. See the rest of this era. 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 … [Read more...]

This tutorial will assist you in setting up FireEye Integration With BlueCoat Proxy, by using a URL list populated by FireEye to use in the BlueCoat as another web filter. This filter can then be used in BlueCoat policy just like the BCWF, McAfee Smartfilter, etc... … [Read more...]
Check Point Firewall – Detect SSH over Non Standard Ports
My Engineering Years: this post is from my early hands-on infrastructure days, kept for reference. See the rest of this era. Many enterprises deploy proxies these days, but many are not aware that if they are not configured correctly they may be allowing SSH over Non Standard Ports, giving a tech savvy employee the keys to exploit this fault. Most times this is SSH over HTTP/HTTPS, but can also be over other ports, which is less common. Blue Coat proxies detect and drop this type of activity by … [Read more...]
Blue Coat ProxySG – ICAP, deferred scanning, and data trickling
My Engineering Years: this post is from my early hands-on infrastructure days, kept for reference. See the rest of this era. 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 … [Read more...]
