SSCP Systems and Application Security Practice Question
This SSCP practice question tests your understanding of systems and 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.
Exhibit
Refer to the exhibit.

[IDS Alert]
Timestamp: 2023-10-05 14:23:45
Signature: ET WEB_SERVER Possible SQL Injection Attempt
Source IP: 192.168.1.100
Destination IP: 10.0.0.50
Payload: ' OR '1'='1' --
```
Refer to the exhibit. A web server at 10.0.0.50 received the payload shown. What is the MOST likely impact if the web application is vulnerable?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Authentication bypass via SQL injection.
The payload shown is a classic SQL injection attempt, specifically targeting authentication logic by injecting a tautology (e.g., ' OR '1'='1) into a login field. If the web application is vulnerable, this bypasses authentication by making the SQL query always return true, granting unauthorized access without valid credentials.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Directory traversal to read sensitive files.
Why it's wrong here
No path traversal syntax in payload.
✗
Remote code execution on the web server.
Why it's wrong here
SQL injection does not directly execute system commands.
✓
Authentication bypass via SQL injection.
Why this is correct
The payload modifies SQL query to always return true.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Cross-site scripting (XSS) attack leading to session theft.
Why it's wrong here
The payload is SQL, not JavaScript.
Common exam traps
Common exam trap: answer the scenario, not the keyword
ISC2 often tests the distinction between injection types by embedding payload syntax that mimics SQL (e.g., single quotes and OR clauses) to mislead candidates into choosing XSS or directory traversal, which use different characters and contexts.
Trap categories for this question
Command / output trap
SQL injection does not directly execute system commands.
Detailed technical explanation
How to think about this question
SQL injection exploits improper sanitization of user input in SQL queries, often using single quotes to break out of string literals. In authentication bypass, the injected condition (e.g., ' OR 1=1 --) modifies the WHERE clause to always evaluate true, bypassing password checks. Real-world examples include the 2008 Heartland Payment Systems breach, where SQL injection led to massive data theft.
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 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.
