    Study Notes

    Contingency Plans

    • There are 5 types of contingency plans: Business Impact Analysis (BIA), Incident Response Plan (IR plan), Disaster Recovery Plan (DR plan), Business Continuity Plan (BC plan), and Crisis Management Plan (CM plan)

    Business Impact Analysis (BIA)

    • Conducted in 3 stages: determine mission/business processes and recovery criticality, identify resource requirements, and identify recovery priorities for system resources
    • Aims to identify critical business processes and resources to ensure continuity in a disaster

    Incident Response Plan (IR plan)

    • Activated when an organization detects an incident that affects it
    • Computer Security Incident Response Team (CSIRT) is responsible for designing and managing the IR plan
    • Focuses on quick and efficient containment and resolution of incidents

    Disaster Recovery Plan (DR plan)

    • A written document that focuses on protecting and restoring IT functions
    • Plans for creating fault tolerance through redundancy to improve high availability (HA)
    • Focuses on reestablishing IT at the primary site

    Business Continuity Plan (BC plan)

    • Ensures critical business functions can continue in a disaster until DR efforts are complete
    • Activated concurrently with the DR plan when needed
    • Focuses on reestablishing critical functions at an alternate site

    Crisis Management Plan (CM plan)

    • Focuses on the effects of a disaster on people rather than information assets
    • Some organizations include crisis management as a subset of the DR plan

    Key Concepts

    • Maximum Tolerable Downtime (MTD): the maximum amount of time a system or service can be down before affecting the business mission
    • Recovery Point Objective (RPO): the amount of time between the loss of data and the last backup
    • Recovery Time Objective (RTO): the time during which the system is recovered; must be equal to or less than MTD
    • Work Recovery Time (WRT): the actual time it takes to recover from an outage, influenced by factors beyond IT's control

    NIST Incident Response Life Cycle

    • 4 stages: Preparation, Detection and Analysis, Containment, Eradication and Recovery, and Post-Incident Activity
