Inputs

  1. GV51: Enterprise Incident Response Documentation

  2. Date of last update or review of the documentation

Operations

  1. Determine whether the enterprise documents an incident response process: GV52 by reviewing Input 1 GV51. Input 1 can be an incident response plan or other documentation.
    1. If documentation for an incident response process exists, M1 = 1

    2. If documentation for an incident response process does not exist, M1 = 0

  2. Determine whether the documentation, at a minimum, outlines the following components: roles and responsibilities, compliance requirements, and a communication plan
    1. For each component included, assign a value of 1. Sum the values. (M2)

  3. Compare Input 2 to current date and capture timeframe in months (M3)

Measures

  • M1 = Output of Operation 1

  • M2 = Count of components included for incident response process documentation

  • M3 = Timeframe since last update or review of documentation in months

Metrics

  • If M1 is 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.

Completeness

Metric

The percentage of components included in documentation for
designated incident handling personnel
