BIA
A Business Impact Analysis (BIA) identifies critical processes and the impact of their disruption to prioritize recovery. CISA uses the BIA to derive recovery objectives such as RTO and RPO for resilience planning.
All CISA Terms
IS Audit
IS Audit is the formal, independent examination of information systems, controls, and processes to assess whether they safeguard assets, maintain integrity, and meet objectives.
Audit Evidence
Audit Evidence is the information an auditor gathers — through inspection, observation, inquiry, and reperformance — to support audit conclusions.

Change Management
Change Management is the controlled process for requesting, approving, testing, and deploying changes to systems.
Post-Implementation Review
A Post-Implementation Review evaluates a completed system against its objectives, budget, and expected benefits after go-live.
BIA
A Business Impact Analysis (BIA) identifies critical processes and the impact of their disruption to prioritize recovery.
RTO and RPO
RTO and RPO are recovery objectives: Recovery Time Objective is the target time to restore a process, and Recovery Point Objective is the maximum tolerable data loss measured in time.
Disaster Recovery
Disaster Recovery is the set of plans and capabilities for restoring IT systems and data after a disruptive event.
Identity and Access Management
Identity and Access Management (IAM) governs how identities are provisioned and what resources they may access, enforcing least privilege.
Encryption
Encryption transforms readable data into ciphertext reversible only with a key, protecting confidentiality in storage and transit.
