Certified Linux Forensic Investigation

This specialist-level course is for experienced forensic investigators who want to acquire the knowledge and skills to navigate, identify, capture and examine data from Linux-based systems. You will develop knowledge and skills to identify, collect, analyse and interpret data from Linux systems.

Linux is an increasingly popular operating system. This two-day course will provide you with a practical understanding from a forensic perspective of how to deal with a Linux system, and requires no previous Linux knowledge. This will be demonstrated and applied to reinforce understanding using both a Linux environment and Windows based forensic software.

Who should attend?
Forensic practitioners, systems administrators and cyber investigators who want to extend their experience from Window-based systems to the Linux environment.
