Security Threat Basics

Security Threat Basics

Secure software starts with recognising risk. The OWASP Top 10 gives you and your team a shared vocabulary for the most common web vulnerabilities — injection, broken authentication, broken access control, and more — with a concrete example for each. Simple threat modelling (assets, attacker, entry points, and STRIDE categories) lets you map plausible threats to a feature such as a login flow or a CRUD API before you build it, rather than patching it afterwards. This basic awareness also connects to your obligations under regulation such as the EU Cyber Resilience Act.

Starting Points

• OWASP Foundation. OWASP Top Ten Web Application Security Risks.
• Threat Modeling for Web Applications (university tutorial).
• W3C. Threat Model for the Web.
• Input validation and secure coding

Key Points

• You list and briefly explain the OWASP Top 10 risks in your own words, with at least one concrete example per risk in a web context.
• You analyse a given web app feature (authentication, data entry, admin panel) and identify plausible threats using a simple threat-modelling approach.
• You map vulnerabilities you find to OWASP Top 10 categories and suggest practical, developer-level mitigations.
• You explain at a high level how secure coding, monitoring, and patching contribute to compliance with regulation such as the Cyber Resilience Act.
