Web application security: OWASP Top 10, security testing and WAF
Comprehensive Guide to Web Application Security: OWASP Top 10 (2021) with secure code examples, complete WSTG testing methodology (SQL injection, XSS, SSRF, IDOR, business logic), Burp Suite Pro Workflow, Nuclei Scanning, Security Headers, WAF Configuration, and Compliance Requirements (PCI DSS, BSI IT-Grundschutz, ISO 27001, NIS2). For developers, security teams, and clients commissioning web penetration tests.
Summary: AI security encompasses measures to protect AI/ML systems from attacks, as well as the secure use of AI in security-critical contexts. Large Language Models (LLMs) are of particular importance: the OWASP LLM Top 10 (2025) catalogs the most significant risks, such as prompt injection, training data poisoning, LLM supply chain vulnerabilities, and excessive agency. The EU AI Act and NIST AI RMF establish regulatory frameworks.
