These materials from Dr Ng's Information Security course at RHUL cover fundamental concepts of computer and network security, with a significant focus on access control mechanisms and models like ACLs, capability lists, RBAC, and matrix-based approaches. The texts also explore network security protocols such as IPsec and TLS, alongside methods for intrusion prevention and detection, including firewalls and IDSs. Furthermore, emerging topics like quantum computing and its cryptographic implications, alongside software vulnerabilities and malicious software, are introduced to provide a broader understanding of contemporary security challenges.
