Input Validation Bug Pattern Analysis

A Input Validation Bug Pattern Analysis is a bug pattern analysis that specializes in identifying recurring input validation failures and data sanitization errors in user input processing.

• AKA: Input Sanitization Bug Pattern Analysis, Input Verification Bug Pattern Analysis, User Input Bug Pattern Analysis, Data Validation Bug Pattern Analysis.
• Context:
  • It can typically detect injection vulnerability patterns from unsanitized input.
  • It can typically identify boundary check failures in input constraints.
  • It can often discover validation-related root cause patterns in security breaches.
  • It can often generate validation-specific code enhancement suggestions for input security.
  • It can range from being a Simple Input Validation Bug Pattern Analysis to being a Complex Input Validation Bug Pattern Analysis, depending on its validation complexity.
  • It can range from being a Client-Side Input Validation Bug Pattern Analysis to being a Server-Side Input Validation Bug Pattern Analysis, depending on its validation location.
  • It can range from being a Format Input Validation Bug Pattern Analysis to being a Semantic Input Validation Bug Pattern Analysis, depending on its validation type.
  • It can range from being a Single-Field Input Validation Bug Pattern Analysis to being a Cross-Field Input Validation Bug Pattern Analysis, depending on its validation scope.
  • It can apply regular expression patterns for format checking.
  • It can support validation-focused preventive code maintenance processes.
  • ...
• Examples:
  • Security Input Validation Bug Pattern Analysises, such as:
    • SQL Injection Validation Pattern Analysis for database query inputs.
    • XSS Validation Pattern Analysis for HTML content inputs.
    • Command Injection Validation Pattern Analysis for system command inputs.
  • Format Input Validation Bug Pattern Analysises, such as:
    • Email Validation Pattern Analysis for email format errors.
    • URL Validation Pattern Analysis for web address errors.
    • Date Format Pattern Analysis for temporal input errors.
  • ...
• Counter-Examples:
  • Output Encoding Analysis, which handles output sanitization rather than input validation.
  • Authentication Analysis, which verifies user identity rather than input data.
  • Business Rule Validation, which checks domain logic rather than input formats.
