PR.MA-1: Asset Maintenance Logging — NIST Cybersecurity Framework
Asset maintenance is a critical control point where unauthorized changes can slip through undetected. PR.MA-1 requires your organization to document all maintenance and repair activities while ensuring only approved tools are used. Without proper logging, you lose visibility into who accessed your systems and what changes were made.
What this means
This control requires your organization to maintain detailed records of all asset maintenance and repair activities. Every maintenance action must be logged with clear documentation, and only pre-approved and controlled tools can be used during these activities. This creates an audit trail that demonstrates oversight and prevents unauthorized modifications disguised as routine maintenance.
How to comply
- 1.Establish a maintenance request workflow that requires approval before any work begins on organizational assets
- 2.Create a comprehensive inventory of approved maintenance tools and keep it updated as tools are added or retired
- 3.Document every maintenance activity with the asset identifier, date, time, person responsible, and work performed
- 4.Implement a centralized log or ticketing system to track all maintenance records for audit and compliance purposes
- 5.Restrict access to approved tools through access controls and prevent use of unapproved tools through technical enforcement
- 6.Review maintenance logs regularly to identify unauthorized or suspicious activity patterns
- 7.Retain maintenance records according to your data retention policy and regulatory requirements
Evidence auditors look for
- Maintenance request tickets showing approval chain before work begins
- Asset maintenance log showing date, technician name, asset ID, and work performed
- Approved tools list with sign-off and update dates
- Access control lists limiting tool usage to authorized personnel only
- Maintenance log audit reports for a 12-month period
- Incident records where unauthorized maintenance attempts were blocked or detected
- Tool inventory reconciliation reports
