SSCP Security Monitoring & Incident Detection 2 — Questions and Answers
Question 1: Which metric is most useful for measuring the effectiveness of a security monitoring program?
- Mean Time to Detect (MTTD) (Correct answer)
- Number of firewalls deployed
- Total bandwidth consumed by logs
- Number of security analysts on staff
Correct answer: Mean Time to Detect (MTTD)
MTTD measures how quickly threats are identified, directly reflecting the effectiveness of detection capabilities.
Question 2: What is the primary purpose of a honeypot in security monitoring?
- To speed up legitimate network traffic
- To attract and study attacker behavior (Correct answer)
- To encrypt sensitive data at rest
- To balance load across web servers
Correct answer: To attract and study attacker behavior
Honeypots are decoy systems designed to lure attackers and gather intelligence on their tactics and techniques.
Question 3: An analyst notices that a server is making DNS requests to randomly generated domain names at regular intervals. This behavior most likely indicates:
- Normal software update activity
- Domain Generation Algorithm (DGA) malware (Correct answer)
- A misconfigured DNS resolver
- IPv6 transition tunneling
Correct answer: Domain Generation Algorithm (DGA) malware
DGA malware generates random domain names to communicate with command-and-control servers, evading static blocklists.
Question 4: Which log source is most critical for detecting lateral movement within a Windows environment?
- Web server access logs
- Windows Security Event logs (Event ID 4624/4625) (Correct answer)
- DHCP lease logs
- Firewall egress logs
Correct answer: Windows Security Event logs (Event ID 4624/4625)
Windows Security Event logs record logon successes and failures (4624/4625), enabling detection of credential-based lateral movement.
Question 5: What distinguishes a true positive from a false positive in IDS alerting?
- True positives are generated by signature-based rules only
- A true positive correctly identifies malicious activity; a false positive flags benign activity as malicious (Correct answer)
- False positives occur only in anomaly-based detection
- True positives require manual analyst confirmation before being logged
Correct answer: A true positive correctly identifies malicious activity; a false positive flags benign activity as malicious
A true positive is a correctly identified threat, while a false positive is a benign event incorrectly flagged as malicious.
Question 6: Which technique allows attackers to hide malicious traffic within legitimate HTTPS sessions, making monitoring harder?
- ARP spoofing
- SSL/TLS encryption tunneling (Correct answer)
- VLAN hopping
- MAC flooding
Correct answer: SSL/TLS encryption tunneling
Attackers use SSL/TLS encryption to conceal malicious payloads within legitimate HTTPS traffic, bypassing content inspection.
Question 7: When implementing a security monitoring strategy, what does 'defense in depth' mean for logging?
- Storing all logs on a single hardened server
- Collecting logs from multiple layers including network, host, and application (Correct answer)
- Encrypting logs with multiple algorithms
- Requiring dual analyst approval for log deletion
Correct answer: Collecting logs from multiple layers including network, host, and application
Defense in depth in logging means collecting telemetry from network, host, and application layers to ensure comprehensive visibility.
