  • Detecting Legacy Clients and Application - I was recently using PVS in a lab environment and noticed the wealth of legacy application information it provided me. This is great news for organizations, as you likely have some legacy systems and applications. It may be tough to find these with network scanning, firewalls, and no credentials for the systems. System owners may not be forthcoming either. However, with PVS you can find old versions of Firefox connecting to legacy web applications. The traffic never lies! How can folks leverage this to find their own legacy applications, and what do you do once you sense them?
  • Disable "Stuff" Not In use - I'm a firm believer in reducing your attack surface. I like simple things, and this is a simple thing. If you're not using it, turn it off! Whether it's an entire system, a service, or parts of an application, turn it off. With all the technology in use today, you have to work towards reducing the attack surface in every aspect, including even using firewalls! What got me thinking about this?
