The correct answer is SQL injection, as the exhibit clearly shows a URL parameter containing the SQL command DROP TABLE users; encoded with %22%3B%20, which decodes to a double quote and semicolon used to break out of the intended SQL query. This attack is detected by analyzing the URL parameter for SQL injection detection, where special characters like quotes and semicolons are injected to manipulate database commands, and the resulting HTTP 500 status code from the internal host 10.0.0.100 confirms a server-side error from the malicious input. On the Systems Security Certified Practitioner SSCP exam, this scenario tests your ability to recognize common web application attacks by inspecting raw URL parameters and understanding how encoding bypasses basic filters. A common trap is confusing SQL injection with cross-site scripting, but remember that SQL injection targets the database layer with SQL syntax, while XSS uses script tags. Memory tip: think of the semicolon as the “SQL breaker” — if you see a semicolon or encoded quote in a URL parameter, suspect injection.
SSCP Risk Identification, Monitoring and Analysis Practice Question
This SSCP practice question tests your understanding of risk identification, monitoring and analysis. 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.

Correct answer & explanation
✓
SQL injection
The exhibit shows a URL parameter containing SQL injection syntax (DROP TABLE users;). The %22%3B%20 sequence decodes to "; " which is used to break out of a SQL query. The destination is an internal host (10.0.0.100), likely a web application server. A status code of 500 indicates a server error, possibly due to the malicious input. Thus, SQL injection (Option D) is correct. The other options do not match the pattern.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Cross-site scripting (XSS)
Why it's wrong here
XSS typically injects scripts into the response, not SQL syntax in a parameter.
✓
SQL injection
Why this is correct
The parameter contains SQL syntax designed to drop a table, which is characteristic of a SQL injection attack.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Directory traversal
Why it's wrong here
Directory traversal uses '../' to access restricted files, not SQL statements.
✗
Buffer overflow
Why it's wrong here
Buffer overflow exploits involve sending more data than expected to crash or control a process, not SQL commands.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Trap categories for this question
Command / output trap
Buffer overflow exploits involve sending more data than expected to crash or control a process, not SQL commands.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related SSCP NAT questions on configuration and troubleshooting.
