What is Sudo hardening?

Tightening how elevated privileges are granted — least privilege, logging, and avoiding passwordless sudo — so a compromised account can't easily become root.

How it works

sudo is the bridge from your user to root. The safer posture: require a password, log every invocation, and grant only the specific commands a user needs rather than blanket root.

Example

In practiceInstead of full sudo, you grant a user permission to restart exactly one service, logged, instead of all commands.

Should I disable sudo entirely?

No — use it deliberately. Require a password, keep it logged, and scope commands narrowly instead of removing it.
