Title: Maintenance Personnel

Practice:
Supervise the maintenance activities of maintenance personnel without required access authorization.

Further Discussion:
Individuals without proper permissions must be supervised while conducting maintenance on organizational machines. Consider creating temporary accounts with short-term expiration periods rather than regular user accounts. Additionally, limit the permissions and access these accounts have to the most restrictive settings possible.

Example
One of your software providers has to come on-site to update the software on your company’s computers. You give the individual a temporary logon and password that expires in 12 hours and is limited to accessing only the computers necessary to complete the work [a]. This gives the technician access long enough to perform the update. You monitor the individual’s physical and network activity while the maintenance is taking place [a] and revoke access when the job is done.

Potential Assessment Considerations
• Are there processes for escorting and supervising maintenance personnel without required access authorization (e.g., vendor support personnel, short-term maintenance contractors) during system maintenance [a]?
