Cisco interviews Ed Skoudis

Leave a reply

Cisco’s Robb Boyd interviews security expert Ed Skoudis in this episode of Cisco’s Techwise Podcast series.

Ed is a popular SANS instructor and an excellent communicator. He and Robb give an overview of the current Internet security scene, and don’t even try to sell any Cisco products!

Probably the easiest way to get this podcast is to point your podcatcher (like iTunes) to this link and choose the episodes you want. The Skoudis one is called “Crouching Wi-Fi Hidden Dragon” after a section from his book, Counter Hack Reloaded.

Right-click on Start menu, then Explore

If you right-click on the Start menu and choose “Explore” a lot like I do, but never want it to drill down to where it does, here’s a very handy tip that I found.

Disclaimer: If you mess up your registry and don’t have a backup, it’s not my fault.

  1. Run regedit
  2. Navigate to HKEY_CLASSES_ROOT\Folder\shell\explore\ddeexec
  3. Edit the value and replace "%l" and %I with the path you want Explorer to open to. For example: [ExploreFolder("d:\download", d:\download, %S)]

For those who actually read Internet RFC’s (there are a few of us), the ones that get released on April 1 can be hilarious.

This year’s, The Transmission of IP Datagrams over the Semaphore Flag Signaling System (SFSS) is funny.

Here’s part of the introduction:
This document specifies IP-SFS, a method for the encapsulation and
transmission of IPv4/IPv6 packets over the Semaphore Flag Signaling
System (SFSS). The SFSS is an internationally recognized alphabetic
communication system based upon the waving of a pair of hand-held
flags [JCroft, Wikipedia]. Under the SFSS, each alphabetic character
or control signal is indicated by a particular flag pattern, called a
Semaphore Flag Signal (SFS).

I especially like the symbols showing how to hold the flags. Note how the hands wave for the “error” signal:
