Broadband penetration testing

We have spent most of November doing a broadband penetration test for one of our customers. We enjoyed penetration attempts on the perimeter infrastructure and Single Sign-On solution, leak tests on virtualized environments, intrusion tests throughout the internal network and finally reverse engineering of unusual internal application protocols to carry out man-in-the-middle attacks. Even in environments with very good security there are always weak spots and doing a broad security audit lets the customer know where the security efforts should be directed.
