AppSec
A curated list of books, articles, websites, and tools for learning application security across multiple programming languages.
What is AppSec?
Awesome AppSec is a curated GitHub repository that collects high-quality resources for learning about application security. It includes books, articles, websites, blog posts, and self-assessment quizzes covering general security principles and language-specific secure coding practices. The project aims to make security education more accessible and organized for developers.
Developers, security engineers, and students who want to learn or improve their knowledge of application security, secure coding practices, and common vulnerabilities across various programming languages and platforms.
It provides a single, well-organized source of trusted security learning materials, saving time compared to scattered searches, and is maintained by security professionals with community contributions to ensure quality and relevance.
Overview
A curated list of resources for learning about application security
Use Cases
Best For
- Developers seeking a structured introduction to application security concepts
- Finding language-specific secure coding guidelines (e.g., PHP, Java, Python)
- Discovering recommended books and articles on security engineering
- Learning about OWASP Top Ten vulnerabilities and mitigation techniques
- Accessing free security training websites and interactive challenges
- Staying updated with security blogs and news feeds
Not Ideal For
- Security professionals needing automated, real-time vulnerability scanning tools for CI/CD pipelines
- Teams seeking certified, instructor-led security training with hands-on labs
- Developers requiring up-to-the-minute threat intelligence feeds or CVE databases
- Projects focused exclusively on cutting-edge security research from the past 1-2 years
Pros & Cons
Pros
Aggregates high-quality materials like the 'Web Application Hacker's Handbook' and OWASP Top Ten wiki, providing a trusted starting point for learners without scattered searches.
Includes language-specific secure coding standards, such as SEI CERT guides for Java and C, and PHP articles on timing attacks, enabling targeted learning across tech stacks.
Maintained by Paragon Initiative Enterprises with community contributions, ensuring diverse perspectives and ongoing updates, as seen in the contributing guide.
Offers gentle introductions like 'A Gentle Introduction to Application Security' and structured topics, lowering the barrier for newcomers to appsec.
Cons
Many listed books and articles are old, such as 'Cryptography Engineering' (2010) and 'The Art of Software Security Assessment' (2006), which may not reflect modern threats or best practices.
The repository relies on periodic community contributions without automated versioning, leading to potential staleness and gaps in recent security developments.
Numerous resources are marked as non-free (e.g., books with paywalls), which can restrict access for users on tight budgets or in educational settings.
