Making your web application flawless against security attacks is a challenge for every java developer. In this article I will briefly describe common practical development techniques that can help you to achieve it.

OWASP Top 10, a list of the 10 Most Critical Web Application Security Risks, includes following risks:

  • A1 - Injection
  • A2 - Broken Authentication & Session Management
  • A3 - Cross-Site Scripting (XSS)
  • A4 - Insecure Direct Object References
  • A5 - Security Misconfiguration
  • A6 - Sensitive Data Exposure
  • A7 - Missing Function Level Access Control
  • A8 - Cross-Site Request Forgery (CSRF)
  • A9 - Using Components with Known Vulnerabilities
  • A10 - Unvalidated Redirects and Forwards

In this article I will highlight most important java coding techniques for building secure web applications.

Deploying application into secure environment adds some restrictions on logging and log management. OWASP community gives some useful recommendations. OWASP Security Testing Guide Recommendations OWASP Security Testing Guide defines a number of questions to be answered when reviewing applciaiton logging configuration (see OTG-CONFIG-002): 1. Do the logs contain sensitive information? Log files should not contain any sensitive data. Anyway, log file access must be restricted: Event log information should never be visible to end users.

OWASP: list of website security attacks OWASP: list of website vulnerabilities OWASP Development Guide – The OWASP Developer Guide 2014 is a dramatic re-write of one of OWASP’s first and most downloaded projects. The focus moves from countermeasures and weaknesses to secure software engineering. The Developer Guide 2014 is a «first principles» book - it’s not specific to any one language or framework, as they all borrow ideas and syntax from each other.
