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
