A command injection attack occurs by injecting malicious commands into user inputs that are passed to system commands on the server.
3. Which type of input is commonly targeted in SQL injection attacks?
- Numeric inputs
- Text inputs
- Checkbox inputs
- Hidden inputs
Text inputs are commonly targeted in SQL injection attacks, where attackers manipulate text-based input fields.
4. How can parameterized queries contribute to preventing SQL injection attacks?
- By improving server performance
- By enhancing data confidentiality
- By securely handling user input in SQL queries
- By preventing unauthorized access
Parameterized queries contribute to preventing SQL injection attacks by securely handling user input in SQL queries.
5. What is the purpose of input validation in preventing server-side injection attacks?
- To improve server performance
- To enhance data confidentiality
- To validate and sanitize user input to prevent injection vulnerabilities
- To prevent unauthorized access
Input validation prevents server-side injection attacks by validating and sanitizing user input to prevent injection vulnerabilities.
6. How does an attacker exploit a server-side injection vulnerability to manipulate data?
- By improving server performance
- By injecting malicious code or commands into user inputs
- By enhancing data confidentiality
- By preventing unauthorized access
An attacker exploits a server-side injection vulnerability by injecting malicious code or commands into user inputs to manipulate data on the server.
7. What is the role of stored procedures in preventing SQL injection attacks?
- To improve server performance
- To enhance data confidentiality
- To encapsulate and secure SQL queries within the database
- To prevent unauthorized access
Stored procedures encapsulate and secure SQL queries within the database, contributing to preventing SQL injection attacks.
8. How does input sanitization contribute to preventing server-side injection vulnerabilities?
- By improving server performance
- By enhancing data confidentiality
- By removing or neutralizing potentially malicious characters from user input
- By preventing unauthorized access
Input sanitization contributes to preventing server-side injection vulnerabilities by removing or neutralizing potentially malicious characters from user input.
9. What is the potential impact of a successful SQL injection attack?
- Improved server performance
- Data leakage, unauthorized access, or manipulation
- Enhanced data confidentiality
- Prevention of unauthorized access
A successful SQL injection attack can lead to data leakage, unauthorized access, or manipulation of data on the server.
10. How can prepared statements assist in preventing SQL injection attacks?
- By improving server performance
- By enhancing data confidentiality
- By separating SQL code from user input, making injection attacks more difficult
- By preventing unauthorized access
Prepared statements assist in preventing SQL injection attacks by separating SQL code from user input, making injection attacks more difficult.
11. What is the primary goal of an attacker in a LDAP injection attack?
- To improve server performance
- To enhance data confidentiality
- To manipulate and execute unauthorized LDAP queries
- To prevent unauthorized access
The primary goal of an attacker in an LDAP injection attack is to manipulate and execute unauthorized LDAP queries on the server.
12. How does a NoSQL injection attack differ from a traditional SQL injection attack?
- No difference; they both target the same vulnerabilities
- NoSQL injection attacks do not exist
- NoSQL injection attacks target databases that use NoSQL technologies
- SQL injection attacks only target web servers
NoSQL injection attacks target databases that use NoSQL technologies, which have different query structures than traditional SQL databases.
13. Which of the following is a common defense mechanism against injection attacks?
- Session management
- Captcha
- Rate limiting
- Input validation and parameterized queries
Input validation and parameterized queries are common defense mechanisms against injection attacks, including SQL injection and command injection.
14. In the context of SQL injection, what is "stacked queries"?
- A method to improve server performance
- Executing multiple SQL queries in a single injection
- A type of encryption for SQL queries
- A way to prevent unauthorized access
Stacked queries in SQL injection involve executing multiple SQL queries in a single injection to achieve specific outcomes.
15. How can web application firewalls (WAFs) contribute to mitigating injection attacks?
- By improving server performance
- By enhancing data confidentiality
- By filtering and blocking malicious requests containing injection payloads
- By preventing unauthorized access
Web application firewalls (WAFs) can contribute to mitigating injection attacks by filtering and blocking malicious requests containing injection payloads.
16. What type of injection attack involves manipulating XML input?
- XPath injection
- JSON injection
- LDAP injection
- NoSQL injection
XPath injection involves manipulating XML input to execute unauthorized XPath queries.
17. How can the use of stored procedures in database queries help prevent injection attacks?
- By improving server performance
- By enhancing data confidentiality
- By encapsulating and securing SQL queries within the database
- By preventing unauthorized access
Stored procedures encapsulate and secure SQL queries within the database, making it harder for attackers to manipulate and inject malicious code.
18. What is the role of input validation in preventing LDAP injection attacks?
- To improve server performance
- To enhance data confidentiality
- To validate and sanitize user input to prevent injection vulnerabilities
- To prevent unauthorized access
Input validation in LDAP injection attacks helps validate and sanitize user input to prevent injection vulnerabilities in LDAP queries.
19. How does "blind" SQL injection differ from traditional SQL injection?
- There is no difference
- Blind SQL injection does not exist
- Blind SQL injection does not require any user input
- Blind SQL injection occurs when the results of a query are not visible in the application's response
Blind SQL injection occurs when the results of a query are not directly visible in the application's response, making it harder to detect.
20. What is the primary risk associated with successful XML external entity (XXE) injection attacks?
- Improved server performance
- Data leakage and unauthorized access to sensitive information
- Enhanced data confidentiality
- Prevention of unauthorized access
The primary risk associated with successful XML external entity (XXE) injection attacks is data leakage and unauthorized access to sensitive information.
