Access Control Best Practices: Least Privilege, MFA and Audits
Access control works only if the rules behind it are good. Whether you protect a building, a server room or business software, the same few principles apply: give people only what they need, verify who they are, review often and keep a record. This guide sets out those practices in plain terms.
Key takeaways
- Give each person the minimum access their job needs.
- Use more than one factor to verify identity where risk is high.
- Review who has access on a regular schedule.
- Keep audit trails and a clear process for incidents.
Least privilege: only what the job needs
Least privilege means a person, a contractor or a system receives the lowest level of access that lets them do their work. A storekeeper needs the store, not the server room. Granting access by role makes this easier to manage than setting rights person by person, and it limits the damage if a card or password is lost.
Verify identity with more than one factor
A single password or card can be stolen or shared. Multi-factor authentication adds a second check, such as a PIN with a card, a one-time code or a fingerprint. Use it for administrator accounts and for the most sensitive doors first. Our article on physical, logical, role-based and biometric access control compares the main approaches.
Review access on a fixed schedule
People change jobs and leave, and projects end. Without reviews, old rights pile up. Set a regular date to check each group, remove unused cards and accounts, and confirm that managers still agree with what their staff can reach. Remove access on the day someone leaves.
| Practice | How often |
|---|---|
| Remove leavers’ access | On the day they leave |
| Contractor and visitor review | After each project or visit period |
| Role and permission review | On a set schedule agreed by security |
| Log review | Regularly, with a named owner |
Keep audit trails and an incident routine
Logs show who accessed what and when. They support investigations and prove that rules are followed. Decide in advance what happens if a card is lost, a door is forced or an account is misused: who is told, how the credential is blocked and how the event is recorded. See industrial access control for gates, contractors and visitors for how this applies to gates, visitors and vehicles.

Access control best practices: common questions
What is least privilege?
It is the rule that each person gets only the access needed for their job and nothing more.
Is multi-factor needed everywhere?
Prioritise administrator accounts and high-risk areas, then extend as your policy requires.
How often should access be reviewed?
Set a regular schedule that suits your risk, and review after staff or contractor changes.
What should audit logs contain?
The person or credential, the place or system, the time and the result.
