Secure Development Foundations

For technical teams — understand common software vulnerabilities, secure coding habits, authentication, input validation, and dependency risks.

Level: Intermediate Duration: 1 day Format: Workshop · Blended Audience: Developers, Technical teams, Engineering managers

Course overview

Security has to be built in, not bolted on. This course gives developers a practical grounding in the vulnerabilities that cause real-world breaches and the coding habits that prevent them — mapped to familiar frameworks like the OWASP Top 10.

What learners will be able to do

  • Understand the most common classes of software vulnerability
  • Validate and sanitise input to prevent injection attacks
  • Implement authentication and session handling more safely
  • Manage secrets, tokens, and configuration securely
  • Assess and reduce risk from third-party dependencies
  • Build security checks into everyday development workflows

What the course covers

Module 1: How software gets breached

Threat modelling and the OWASP Top 10 in plain terms.

Module 2: Input, output, and injection

Validation, encoding, and parameterised queries.

Module 3: Authentication and access

Passwords, sessions, tokens, and authorisation pitfalls.

Module 4: Secrets and configuration

Keeping credentials and config out of harm's way.

Module 5: Dependencies and the supply chain

Auditing packages and responding to vulnerabilities.
