ROSLYN.SECURITY.CA5381 : Ensure Certificates Are Not Added To Root Store (C#)

See Roslyn-Detected C# Warning Classes for more information.

Summary

By default, the Trusted Root Certification Authorities certificate store is configured with a set of public CAs that has met the requirements of the Microsoft Root Certificate Program. Since all trusted root CAs can issue certificates for any domain, an attacker can pick a weak or coercible CA that you install by yourself to target for an attack - and a single vulnerable, malicious or coercible CA undermines the security of the entire system. To make matters worse, these attacks can go unnoticed quite easily.

This check corresponds to Roslyn rule CA5381. For full rule details, see the Microsoft website: CA5381.
