Quick Answer
The answer is Amazon GuardDuty and AWS Security Hub. GuardDuty continuously monitors for malicious activity and compromised instances using machine learning and threat intelligence, while Security Hub aggregates and prioritizes those findings alongside other security services to provide a single pane of glass. This combination delivers comprehensive threat detection because GuardDuty identifies the threats, and Security Hub centralizes the alerts for unified response. On the AWS Certified Security Specialty SCS-C02 exam, this pairing tests your understanding of how detective controls and aggregation services work together, often appearing in scenario-based questions where a common trap is confusing GuardDuty with CloudTrail (logging) or Inspector (vulnerability scanning). A useful memory tip: GuardDuty is the “detective” that finds the clues, and Security Hub is the “case file” that organizes them into a complete picture.
This SCS-C02 practice question tests your understanding of security logging and monitoring. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A security team wants to detect and alert on potential security threats such as compromised instances or malicious activity within their AWS environment. Which TWO AWS services should be used together to provide comprehensive threat detection?
AWS Security Hub
Aggregates and prioritizes security findings.
AWS CloudTrail
Why wrong: CloudTrail logs API calls, not threat detection.
Amazon Inspector
Why wrong: Inspector is for vulnerability assessments, not ongoing threat detection.
AWS Config
Why wrong: Config tracks configuration changes, not threats.
Amazon GuardDuty
Provides threat detection using machine learning.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
AWS Security Hub
Amazon GuardDuty provides intelligent threat detection, and AWS Security Hub aggregates findings from multiple services including GuardDuty. Option A and Option C are correct. Option B is wrong because CloudTrail is for logging, not threat detection. Option D is wrong because Inspector is for vulnerability assessments. Option E is wrong because Config is for configuration compliance.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
