Operations
- Determine whether the enterprise maintains a service provider management policy by checking for Input 1,
If Input 1 exists, M1 = 1
If Input 2 does not exist, M1 = 0
- Review Input 1 and determine if it includes, at a minimum, the following components: service provider inventory, classification, assessment, monitoring, and decommissioning of service providers
For each component included, assign a value of 1. Sum all values. (M2)
Compare the date from Input 2 with the current date and capture the time frame in months (M3)
Measures
M1 = Output of Operation 1
M2 = Count of components included in the policy
M3 = Timeframe since last update or review of the policy
Metrics
If M1 is a 0, this safeguard receives a failing score. The other metrics don’t apply.
If M3 is greater than twelve months, then this safeguard is measured at a 0 and receives a failing score. The other metrics don’t apply.
