This Skill provides comprehensive guidance and best practices to secure Perl applications against common vulnerabilities like injection attacks, insecure file operations, and improper input handling.
Core Features & Use Cases
- Taint Mode: Understand and implement Perl's taint mode for tracking and validating external data.
- Input Validation: Learn to use allowlists and specific patterns for robust input sanitization.
- Secure Execution: Implement safe process execution using list-form commands and libraries like IPC::Run3.
- Database Security: Prevent SQL injection with DBI parameterized queries and dynamic column validation.
- Web Security: Protect against XSS, CSRF, and configure secure HTTP headers.
- Use Case: Reviewing a Perl web application's code to ensure all user inputs are validated, database queries are parameterized, and sensitive operations are protected against common web exploits.
