Measure the time between each response step

Incident counts depend on how hard an organisation looks. Detection, containment, and recovery intervals can be generated on demand and compared over time.

Under the pillar Attack-and-recovery engineering

The pattern

Do not wait for incidents to produce metrics. Inject known, safe activity that a control claims to detect, and measure the interval to alert, to accurate understanding, and to containment action. Repeat on a schedule with varied techniques.

The resulting numbers are comparable quarter to quarter, which incident counts are not.

Put this to work

Measure the time between each response step application record

Apply Measure the time between each response step to a real piece of work and record what happened.

For
Practitioners, researchers, founders, and operating leaders.
What you keep
A measure the time between each response step application record you can review, revise, and send.
What counts as sound
  • Names a real setting
  • Shows the work before and after
  • Records exceptions
  • Uses an observable result
  • Ends with keep, revise, or stop

The result is a working analysis. Check it against source evidence and qualified judgment.
