Incident commander must resolve whether the incident is contained or still

Situation

Incident commander in a hospital after a weekend EHR outage has one working extract — EDR ransomware canary plus missing backups — after a board meeting in 36 hours that will ask if we are down. If EDR ransomware canary plus missing backups cannot support the incident is contained, the honest Cybersecurity output is hold.

Decision

Incident commander in a hospital after a weekend EHR outage must choose The incident is contained / Still lateral using EDR ransomware canary plus missing backups after a board meeting in 36 hours that will ask if we are down.

Hypotheses to test

• Authorize The incident is contained now; EDR ransomware canary plus missing backups already has the discriminator after a board meeting in 36 hours that will ask if we are down.
• Keep Still lateral in force until EDR ransomware canary plus missing backups is completed after a board meeting in 36 hours that will ask if we are down for incident commander.
• Treat EDR ransomware canary plus missing backups as The incident is contained because both readings appear after a board meeting in 36 hours that will ask if we are down.
• Refuse a Cybersecurity close: incident commander does not have the page the incident is contained turns on in EDR ransomware canary plus missing backups.

Analysis required

• Map identities, standing privileges, and last-use timestamps in EDR ransomware canary plus missing backups to the blast radius of a board meeting in 36 hours that will ask if we are down.
• Name the compensating control that would let incident commander release a reversible hold.

• For this Cybersecurity Incident Response file, read EDR ransomware canary plus missing backups against a board meeting in 36 hours that will ask if we are down and write the one fact that would move the incident is contained for incident commander.
