Old cloud storage links shared long ago often remain active. Many people forget these links still exist. Left unchecked, they can attract unwanted visitors.
A link audit starts with a full inventory. Users should list every file and folder they have ever shared. Cloud accounts usually keep a sharing history for this purpose.
Review each link’s permission settings. Public links allow anyone with the URL to open the file. Restricting access to specific people reduces exposure.
Revoke links that are no longer needed. Most cloud services offer a one-click option to disable sharing. Old links then stop working immediately.
Check links embedded in emails, messages, and documents. These are easy to overlook during a cleanup. Search sent mail for storage domain names to find them.
Set expiration dates on new sharing links. Time-limited access limits the damage if a link leaks. Many providers support this feature by default.
Repeat the audit on a regular schedule. Quarterly reviews keep shared files under control. A short checklist makes the process quick and routine.
