Worked practice questions

The NIST Cybersecurity Framework consists of how many CORE FUNCTIONS?

  1. 3 distinct functions
  2. 10 detailed functions
  3. 7 layered functions
  4. 5 functions
Show answer and solution

Correct answer: D. 5 functions

1. NIST CSF Core has 5 high-level FUNCTIONS that anchor the entire framework. 2. They are: IDENTIFY (asset/risk understanding), PROTECT (safeguards), DETECT (incidents), RESPOND (containment), RECOVER (resilience/restoration). 3. Each function is broken down into CATEGORIES and SUBCATEGORIES with mappings to standards (ISO 27001, NIST SP 800-53, etc.). 4. The 5 functions together form an ongoing CYCLE — security is a continuous process, not a one-off project. _Source: NIST Cybersecurity Framework v1.1, §2.1 (Framework Core), p. 6-8._

Implementing access controls, awareness training, and data security falls under which NIST CSF function?

  1. Identify
  2. Detect
  3. Protect
  4. Recover
Show answer and solution

Correct answer: C. Protect

1. The PROTECT function (PR) covers SAFEGUARDS to ensure delivery of services. 2. Categories include: Identity Management & Access Control (PR.AC), Awareness & Training (PR.AT), Data Security (PR.DS), Information Protection Processes (PR.IP), Maintenance (PR.MA), Protective Technology (PR.PT). 3. Protect implementations include: encryption, MFA, role-based access, security training, secure configurations. 4. Goal: limit or contain the impact of a potential cybersecurity event. _Source: NIST Cybersecurity Framework v1.1, §2.1 — Protect Function, p. 7._

Continuous MONITORING of systems to discover anomalies and cyber events is part of which function?

  1. Identify
  2. Protect
  3. Detect
  4. Recover
Show answer and solution

Correct answer: C. Detect

1. The DETECT function (DE) enables timely DISCOVERY of cybersecurity events. 2. Categories: Anomalies & Events (DE.AE), Security Continuous Monitoring (DE.CM), Detection Processes (DE.DP). 3. Tools include: SIEM (Security Info & Event Mgmt), IDS/IPS, log analysis, behavioural analytics. 4. Critical: detection enables faster response. Average breach dwell time (per industry reports) is months without strong detection. _Source: NIST Cybersecurity Framework v1.1, §2.1 — Detect Function, p. 7._
