T9: Windows Digital Forensics and Incident Response

Tuesday, 4 December 2012
13:30 - 17:00

Knave

Digital forensics and incident response are two of the most critical fields in all of information security. The staggering number of reported breaches in the last year has shown that the ability to rapidly respond to attacks is a vital capability for all organizations. Unfortunately, the standard IT staff member is simply unable to effectively respond to security incidents. Successful handling of these situations requires specific training in a number of very technical areas including file system implementation, operating system design, and knowledge of possible network and host attack vectors.

During this training, students will learn the theory around digital forensics and incident response as well as see how it is applied on the same types of evidence used in real-world investigations. Upon completion of the training, students will be able to effectively preserve and analyze a large number of digital evidence sources, including both on-disk and in-memory data. These skills will be immediately usable in a number of investigative scenarios, and will greatly enhance even experienced investigators' skillset.

Prerequisites. No previous knowledge on digital forensics. Some scripting or Windows systems knowledge would be beneficial, but not mandatory.
