InfoSec BitesInformation Security Manual(ISM): Principles and GuidelinesThis podcast present two distinct perspectives on success and security. The first source, an Information Security Manual (ISM), outlines a comprehensive cybersecurity framework for organisations, detailing guidelines and principles across five key functions: govern, identify, protect, detect, and respond. It emphasizes risk management, the importance of evaluated products, secure IT equipment maintenance, and personnel security training, with specific controls for various data classifications (e.g., OFFICIAL: Sensitive, PROTECTED, SECRET, TOP SECRET).

InfoSec BitesMITRE ATT&CK Matrices: Decoding a Cyberattack's PlaybookThis Podcast offers a comprehensive overview of the MITRE ATT&CK framework, a standardised model for understanding cyber adversary behaviours. It details four distinct matrices: Enterprise, Mobile, Industrial Control Systems (ICS), and Cloud, each tailored to specific technological environments. For each matrix, the document explains various tactics—the objectives of an attack—and their associated techniques—the methods used to achieve those objectives. Real-world examples are integrated throughout to illustrate how these tactics and techniques manifest in actual cyber incidents, such as the SolarWinds attack or the Pegasus spyware. This resource serves to help organisations map threats, improve detection capabi...

InfoSec BitesPost-Quantum Cryptography(PQC): Preparing for the Quantum MenacePost-Quantum Cryptography (PQC), highlighting its critical role in safeguarding digital security against the imminent threat of quantum computers. They explain that PQC involves developing new algorithms resistant to quantum attacks, which could otherwise break current encryption methods like RSA and ECC, primarily through Shor's algorithm. The video detail the NIST standardisation process, which has identified key PQC algorithms such as lattice-based ML-KEM and ML-DSA, and hash-based SLH-DSA, with code-based HQC as a backup, noting their varying strengths and weaknesses. They underscore the urgency of PQC migration due to the "Harvest Now, Decrypt Later" threat, where adversaries store encrypted data...
