What is the primary purpose of output encoding in a web application?

To validate user input on the server side

To encrypt data stored in the database

To compress data to reduce bandwidth usage

To prevent cross-site scripting (XSS) by neutralizing malicious characters in user-supplied data before rendering

A security analyst is reviewing web server logs and sees a series of requests like: GET /login HTTP/1.1 followed by POST /login with a body containing username=admin&password=try123. The requests are coming from a single IP address at a rate of 10 per second, and the server responds with 401 Unauthorized each time. What is the most likely issue and the best immediate response?

A CSRF attack is being attempted; add CSRF tokens to the login form.

A brute-force attack is in progress; implement rate limiting and account lockout policies on the login endpoint.

A session fixation attack is occurring; regenerate session IDs after login.

A DDoS attack is flooding the login page; block the IP address at the firewall.

A company is redesigning its web application to improve scalability. Currently, the application uses a monolithic server that renders HTML and handles all business logic. The team wants to separate the front-end and back-end so that the front-end can be served as static files and the back-end provides a RESTful API. Which architecture change best achieves this goal?

Add more servers to the monolithic deployment

Convert the back-end to a RESTful API and serve static front-end files separately

Use a database as the front-end

Move the front-end to a CDN and keep the monolithic server for API and rendering

Which web vulnerability occurs when an attacker injects malicious SQL code into a query, potentially allowing unauthorized data access or manipulation?

Cross-site request forgery (CSRF)
