One of my current projects is Enhancing DoS Tolerance in VoIP systems. The aim of this project is to enhance the tolerance against DoS attacks such that the VoIP components keep on providing the service gracefully during and after the DoS attack.
 

Avaya Labs released the software, Libsafe based on my other research effort, as Free Linux software dealing with providing protection against stack smashing attacks. Libsafe software prevents electronic intruders from overflowing an application program’s buffer memory to gain unauthorized access. Many Books, research papers, and other articles covered Libsafe with favorable comments. Lots of email such as “ Just wanted to thank you guys for Libsafe. I’ve tested it out and it’s pretty damn effective. Thanks for providing Libsafe for my and other linux guru’s user.”
