Educational Videos

The Polytechnic Institute of New York University has some excellent videos of presentations from their Penetration Testing and Vulnerability Analysis course. These videos are great for getting a quick introduction to the topics they cover:

Source Code Auditing
Identify vulnerabilities and programmer errors by auditing source code

Reverse Engineering
Understand, modify, and analyze compiled applications and systems to identify vulnerabilities

Exploitation
Take advantage of vulnerabilities to gain access to restricted data and break security policies

Fuzz Testing
Uncover high volumes of software security errors with a special type of negative testing

Client-side Exploits
Indirectly attack the users in your network and automate the collection of data from them

Web Hacking
Identify and exploit vulnerabilities in web applications to gain access to sensitive data and escalate privileges to the host operating system
