Ensure bind (DNS server) is not installed

package-bind-removed · RHEL ≥ 8 · 2 impls

Description

The bind package provides DNS server functionality. Unless the system is a designated DNS server, this package should not be installed.

Rationale

Running a DNS server increases the attack surface. DNS servers have been historically targeted for cache poisoning, amplification attacks, and other exploits. Remove if not required.
