BUSINESS ACCESS REVIEWS: REGULARLY CHECK WHO CAN ACCESS WHAT
Access reviews are deliberate checks to determine whether people, accounts and applications still have the permissions they need.
Access that was appropriate six months ago may no longer be appropriate today.
The central principle is:
ACCESS SHOULD BE REVIEWED, NOT ASSUMED.
1. WHY ACCESS REVIEWS MATTER
People change roles. Projects end. Vendors change. Applications are added. Temporary permissions are forgotten.
Without periodic review, access can accumulate quietly.
2. WHAT TO REVIEW
Depending on the organization, review:
- User accounts
- Administrator accounts
- Shared accounts
- Cloud applications
- Sensitive folders
- Financial systems
- Customer-information systems
- Connected applications
- Vendor access
- API or service access where applicable
3. PRIORITIZE HIGH-IMPACT ACCESS
A small business does not need to begin with an enormous audit.
Start with systems that could cause significant harm if misused, such as financial systems, business email, administrator consoles, customer information and domain management.
4. ASK SIMPLE QUESTIONS
For every important permission, ask:
- Who has it?
- Why do they have it?
- Do they still need it?
- Is the permission greater than necessary?
- Is the account active?
- Is the person still in the relevant role?
- Is the access being used as expected?
5. REMOVE OR REDUCE UNNECESSARY ACCESS
When an access review identifies permissions that are no longer needed, remove or reduce them through the service's official controls.
Document important changes where appropriate.
6. BUSINESS EXAMPLE
A contractor was given access to a shared project folder for a three-month project.
The project ended, but the access remained active for another year because nobody reviewed it.
The contractor may be trustworthy, but the business no longer has a reason to maintain the access.
7. SIMPLE REVIEW SCHEDULE
The appropriate frequency depends on the risk and size of the organization.
High-impact administrator and financial access may deserve more frequent review than ordinary low-risk access.
The important thing is to establish a repeatable process rather than relying on memory.
WHY THIS MATTERS
Access reviews turn security from a one-time setup exercise into an ongoing business process.
They help organizations discover forgotten permissions before those permissions become a problem.
VERIFY BEFORE YOU TRUST.
Trust should not be permanent access. Access should remain connected to a current and legitimate business need.
