Using AI to reduce false positives in secrets scanners 2024-02-27 at 08:02 By Help Net Security As development environments grow more complex, applications increasingly communicate with many external services. When a software development project communicates with an external service, it utilizes a token or “secret” for authentication. These tokens are the glue that keeps any
