This will be the place of my security repository for my customers and students. Here are some first files...
Be patient, new stuff will arrive soon.
I am very interested in wireless security especially WLAN security. Besides Cisco WLAN courses I also offer a WLAN Security Workshop (WLSW). The WLSW is targeted for people who are really interested in many technical details, practical attacks, and the many security holes a misconfigured WLAN could have. Contact Fast Lane or me if you want to book one of these courses.
Here are some updated docs:
Much more WLAN docs can be found here.
Long time ago I listed the most interesting issues regarding Cisco's PIX firewall as addendum to the SNPA course (the Cisco Firewall course). I did not maintain this document for some years (the date on the slides only reflects the version of the powerpoint master) but almost all things are still valid and important. If you are new to the PIX (now ASA) then this document might give you an overview.
An overview about interesting ASA features (and how and when to use them) can be found in here. I will occasionally update that document.
Recently I wrote a summary about of how to harden your switched network, in case you have Cisco switches. Note that this is not comprehensive, there are some more issues involved. I must emphasize that it is also important to understand the particular attack scenarios and when which design is appropriate.I will occasionally update this document.
