High-Yield Technical Questions & Detailed Model Answers

Q1. Explain the 6 phases of the NIST SP 800-61 Incident Handling Guide and describe how you isolate an endpoint compromised by active ransomware.

💡 Model Answer: The NIST 6 phases are: (1) Preparation; (2) Detection & Analysis; (3) Containment (short-term & long-term); (4) Eradication; (5) Recovery; and (6) Post-Incident Activity (Lessons Learned). To isolate a ransomware-compromised host: (1) Immediately execute network containment via EDR agent or drop switch port to prevent lateral SMB/RPC spread; (2) Preserve volatile memory (RAM capture) for forensic key extraction; (3) Terminate malicious processes and persistence mechanisms; (4) Revoke compromised user/service account Active Directory credentials; (5) Rebuild host from verified baseline image before restoring data from air-gapped immutable backups.

Q2. Differentiate between True Positive, False Positive, True Negative, and False Negative alerts in a Security Operations Center and calculate the Precision of a SIEM correlation rule.

💡 Model Answer: True Positive (TP) = Correctly alerted on actual malicious activity; False Positive (FP) = Inadvertently alerted on benign activity; True Negative (TN) = Correctly ignored benign activity; False Negative (FN) = Failed to detect actual malicious attack (most critical danger). Precision = TP / (TP + FP), measuring the proportion of positive alerts that were genuinely malicious. Recall (Sensitivity) = TP / (TP + FN), measuring the proportion of actual attacks detected by the correlation rule.

Q3. Describe the MITRE ATT&CK Enterprise Matrix structure and explain how an attacker leverages Kerberoasting (T1558.003) for privilege escalation in Active Directory.

💡 Model Answer: MITRE ATT&CK categorizes adversary behaviors into 14 Tactics (e.g. Initial Access, Persistence, Privilege Escalation, Lateral Movement, Exfiltration) containing hundreds of detailed Techniques (TTPs). Kerberoasting (T1558.003) exploits Kerberos Ticket Granting Service (TGS) requests: Any authenticated domain user requests a TGS ticket for a Service Principal Name (SPN) associated with a service account; the domain controller returns the ticket encrypted with the service account's NTLM password hash; the attacker extracts the ticket from memory and performs offline brute-force cracking using hashcat to recover the plaintext service account password.

PART 4

Authority Selection Board Viva Voce Q&A

Scenario 1: Defending Critical Digital Infrastructure Under Active Attack

Board Question: "How will you coordinate rapid incident response and crisis communication during a major cyber breach on a core government digital service?"

💡 Strategy: Articulate enacting predetermined incident response plans, isolating affected infrastructure, preserving digital evidence for forensics, briefing the National CERT, and releasing measured public advisories.

Scenario 2: Balancing Security, Data Privacy & User Experience

Board Question: "How do you resolve conflicts between strict security controls and the demand for fast, seamless citizen user experience in public digital apps?"

💡 Strategy: Discuss Zero-Trust architecture, risk-based adaptive authentication, automated API security, and Privacy by Design principles that protect users transparently without unnecessary friction.

Scenario 3: Fiscal Transparency & Public Sector Auditing

Board Question: "What measures ensure complete transparency in procurement and financial management of high-value federal technology contracts?"

💡 Strategy: Reiterate strict adherence to PPRA rules 2004, open international competitive bidding, robust IFRS accounting records, and proactive internal audit scrutiny.

Scenario 4: Statutory Compliance & National Secrecy

Board Question: "What are your legal and ethical duties regarding sensitive government data and official secrets?"

💡 Strategy: Affirm absolute compliance with the Official Secrets Act, National Cybersecurity Policy, clean background vetting, and zero tolerance for unauthorized data sharing.
