SQL injection and cross-site scripting are examples of which type of threat?

• A. Network threats
• B. Web application threats
• C. Physical security threats
• D. System configuration threats

Answer: (B)

SQL injection and cross-site scripting (XSS) are both classified as web application threats because they specifically exploit vulnerabilities within web applications. These types of attacks target the way web applications handle user input and interact with databases or browsers. In the case of SQL injection, an attacker can manipulate query inputs to execute arbitrary SQL commands, potentially compromising the database and accessing sensitive data. Cross-site scripting, on the other hand, involves injecting malicious scripts into web pages viewed by other users, which can lead to session hijacking, data theft, or spreading malware. Web application threats focus primarily on the security issues that arise in web environments. They arise from the interactions between users, web servers, databases, and the way an application processes data. Recognizing these attacks as web application threats helps in understanding the importance of securing applications against input validation, ensuring proper output encoding, and implementing stringent security measures. The other types of threats listed—network threats, physical security threats, and system configuration threats—do not specifically pertain to vulnerabilities exploited through web applications. Network threats typically involve attacks on the infrastructure of a network, while physical security threats relate to unauthorized access to physical assets, and system configuration threats concern improper configurations that could lead to exploitation.
