Java Application Security: Protecting Data from Vulnerabilities and Attacks

The book "Java Application Security" is a practical guide that helps developers of any level understand and eliminate the most critical vulnerabilities in Java code. In today's world, where data leaks and cyberattacks are becoming commonplace, knowledge of security fundamentals is not a luxury but a necessity for every programmer.

The author, Alexey Smirnov, is an experienced Java developer and information security specialist who has consolidated years of experience working with large enterprise projects. The book is written in a lively, understandable language, without excessive academicism, but with deep immersion into the topic.

What you will learn from the book:

• Java Security Basics: JVM security model, ClassLoader, SecurityManager, cryptographic APIs (JCA/JCE).
• OWASP Top 10 for Java: analysis of each vulnerability with real code examples and protection methods.
• Protection against SQL Injections: proper use of PreparedStatement, JPA/Hibernate, and input validation.
• Secure Network Operations: REST API protection, HTTPS configuration, prevention of SSRF and XXE attacks.
• Spring Security in Practice: configuring authentication, authorization, CSRF and CORS protection.
• Security of Multithreaded Applications: protection against race conditions, deadlocks, and memory leaks.
• Audit and Logging: how to properly log security events without disclosing confidential data.
• Analysis Tools: overview of static analyzers (FindBugs, SpotBugs, SonarQube) and dynamic testing.

Who this book is for:

• Junior and Middle level Java developers who want to improve the quality of their code.
• Team Leads and architects responsible for project security.
• Students and beginner programmers learning Java.
• DevOps engineers who want to understand how to protect Java applications at the deployment stage.

The book contains numerous code listings, practical tasks, and audit checklists. All examples are relevant for Java 8, 11, 17 and newer, as well as for popular frameworks Spring Boot, Hibernate, and Jakarta EE.

After reading, you will be able not only to write secure code but also to conduct security-focused code reviews, configure protection at the application and infrastructure level, and respond competently to incidents.

This is not just a book — it is your personal security consultant that will help you avoid costly mistakes and protect user data.
