Look inside

XYZ Services Company, the consulting and outsourcing firm you work for, recently experienced a massive failure in its IT Infrastructure. While it’s working on getting the environment back up and running, the company urgently needs to identify potential vulnerabilities in the digital signatures used by the employees for two-factor authentication. Applying PowerShell scripting best practices, you’ll write a script that uses the switch statement and its regex parameter to extract a list of digital signatures from an input file, identify matching strings that satisfy specific conditions, classify them as required, and send them to log files. When you’re done, the information security officer will thank you for helping prevent future security issues.

This project is designed for learning purposes and is not a complete, production-ready application or solution.
