Question 15

Explain what is cross-site scripting (XSS) and how to prevent it?
Answer:
Cross-Site Scripting (XSS) is a vulnerability that allows attackers to inject malicious scripts into websites viewed by other users. To prevent XSS, you should sanitize user inputs, encode outputs, and use Content Security Policy (CSP).

Question 16

What is SQL injection and how can it be prevented?
Answer:
SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution. Prevention involves using parameterized queries or stored procedures, input validation, and least privilege principles.

Question 17

Describe your experience with network security tools like Wireshark or tcpdump.
Answer:
I have used Wireshark and tcpdump for network traffic analysis, troubleshooting, and security investigations. I can capture and analyze packets to identify anomalies, diagnose network issues, and detect malicious activity.
