- A
Web application firewall (WAF)
Why wrong: WAF operates at the network layer and cannot analyze application logic deeply.
- B
Intrusion detection system (IDS)
Why wrong: IDS monitors network traffic, not application context.
- C
Runtime application self-protection (RASP)
RASP instruments the application runtime to detect and block attacks based on application logic.
- D
Static application security testing (SAST)
Why wrong: SAST is a static analysis tool, not runtime.

CCSP Cloud Application Security Practice Question
This CCSP practice question tests your understanding of cloud application security. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Which runtime security control monitors application behavior and can block attacks by analyzing application logic and context?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Runtime application self-protection (RASP)
C is correct because Runtime Application Self-Protection (RASP) is a security technology that is integrated into an application's runtime environment, allowing it to monitor actual application behavior and context (e.g., input validation, SQL queries, API calls) in real time. Unlike external controls, RASP can understand the application's logic and data flow, enabling it to block attacks such as SQL injection or command injection by analyzing the specific context of each request.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between network-layer controls (WAF) and application-layer controls (RASP), and the trap here is that candidates mistakenly choose WAF because they think it 'analyzes application logic' when in fact WAFs rely on signatures and patterns, not runtime context.
Detailed technical explanation
How to think about this question
RASP typically uses instrumentation agents (e.g., Java agents via the JVM Tool Interface or .NET profilers) to intercept function calls, such as database queries or file I/O, and applies taint tracking to determine if untrusted input reaches a sensitive sink. For example, in a real-world scenario, RASP can detect a second-order SQL injection where a WAF might miss it because the malicious payload is stored in a database and later executed, but RASP sees the actual query construction at runtime. This contextual awareness allows RASP to enforce a whitelist of allowed operations, blocking only malicious requests without false positives that might affect legitimate traffic.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
