Read the CyBOK Forensics Knowledge Area introduction
CyBOK Introduction
The Cyber Security Body Of Knowledge is a comprehensive Body of Knowledge to inform and underpin education and professional training for the cyber security sector. The CyBOK project aims to bring cyber security into line with the more established sciences by distilling knowledge from major internationally-recognised experts to form a Cyber Security Body of Knowledge that will provide much-needed foundations for this emerging topic. The project, funded by the National Cyber Security Programme, is led by the University of Bristol's Professor Awais Rashid, along with other leading cyber security experts - including Professor Andrew Martin, Professor Steve Schneider, Dr Yulia Cherdantseva, Dr Rod Chapman and Dr Marina Krotofil.

Use CyberChef to base64 encode and decode data
CyberChef is a simple, intuitive web app for carrying out all manner of "cyber" operations within a web browser. These operations include simple encoding like XOR and Base64, more complex encryption like AES, DES and Blowfish, creating binary and hexdumps, compression and decompression of data, calculating hashes and checksums, IPv6 and X.509 parsing, changing character encodings, and much more. The tool is designed to enable both technical and non-technical analysts to manipulate data in complex ways without having to deal with complex tools or algorithms. It was conceived, designed, built and incrementally improved by an analyst in their 10% innovation time over several years.
