Secure Shell Server (sshd) Execution

No violationsstackroxhighruntime

Detects container running the SSH daemon

Rationale: The secure shell server allows shell access to a container, which can be dangerous.
Remediation: If ssh is absolutely required, ensure that it is not using default authentication. Otherwise, consider removing it from the container altogether.
