All degrees

Cybersecurity

Systems, networks and cryptography, seen by the people who have to defend them.

  1. 01Programming fundamentalsValues and types, memory, control flow, functions, recursion, lists and strings, errors and tests: the first programming course of any CS degree.
  2. 02Computer architectureFrom bits and gates to the processor: number systems, logic, the datapath, instruction sets, pipelines, caches, buses and parallel hardware.
  3. 03Operating systemsKernel and system calls, processes and threads, scheduling, synchronisation, paging and virtual memory, file systems, I/O and virtualisation.
  4. 04Computer networksLayers, frames, error detection, subnetting, routing algorithms, TCP and network performance: the networking course of a computer science degree.
  5. 05CryptographyFrom classical ciphers to AES, hashes, RSA, Diffie–Hellman, certificates and TLS, and the practical mistakes that break real systems.
  6. 06DatabasesFrom Codd's relational model to SQL, normalisation, transactions, indexes and NoSQL: how data is modelled, queried and kept correct under load.
