Least Privilege: How to Limit Access the Smart Way

Here’s a quiet truth: most damage in a breach comes from an account that had far more access than it needed. Least privilege is the simple idea that people (and apps) should only hold the keys to the rooms they actually use.

Why it works

If an attacker phishes a staff member who can only reach their own files, the blast radius is small. If that same person was a full administrator, it’s a catastrophe. Limiting access limits the damage — full stop.

How to apply it

• Separate admin from daily-use accounts. Never run everyday work as a full administrator.
• Grant by role, not by favor. Give access based on the job, and remove it when the job changes.
• Review regularly. Quarterly, ask “does this person still need this?” — especially for departed staff and old shared logins.
• Don’t make one account the keys to the kingdom.

Common mistakes

• Everyone’s an admin “to make things easier.”
• Shared logins nobody owns.
• Access granted once and never revisited.
