• Online, Self-Paced

Input validation is used to check potentially dangerous inputs but when software does not validate this input properly, an attacker is able to craft the input in a form that is not expected by the rest of the application. This course introduces ways to identify and mitigate this security weakness, referenced as CWE-20 by the 2020 CWE Top 25.

Learning Objectives

On successful completion of this course, learners should have the knowledge and skills to:

  • Use language-theoretic security (LangSec) techniques that characterizes inputs using a formal language and builds "recognizers" for that language
  • Use an input validation framework such as Struts or the OWASP ESAPI Validation API
  • Apply an "accept known good" input validation strategy
  • Perform validation of sources when an application combines data from multiple source after they have been combined

Framework Connections

The materials within this course focus on the NICE Framework Task, Knowledge, and Skill statements identified within the indicated NICE Framework component(s):
