Assessment Script Powered by AISandbox-executed

A standalone Shell script to assess this control automatically. Review before running it in your environment.

Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.

if rpm -q unbound >/dev/null 2>&1; then echo "FAIL"; exit 1; else echo "PASS"; exit 0; fi

Remediation

Configure RHEL 10 to not have the unbound package installed with the following command:

$ sudo dnf -y remove unbound
