Cybersecurity

Threat modelling, common attack classes, cryptography, authentication, and defensive practices for building more secure systems.

Security is not a feature you add at the end. This course covers threat modelling, cryptographic primitives, authentication and access control, the most common attack classes, and the development practices that reduce exposure.

Outcomes

  • Produce a structured threat model for a software system
  • Apply symmetric and asymmetric cryptography to real authentication problems
  • Identify and exploit common web vulnerabilities in a controlled sandbox environment
  • Audit code for access-control weaknesses and implement targeted fixes
