"A cross-site scripting attack or XSS is a type of injection, in which malicious scripts are injected into the otherwise benign and trusted website. It is typically in the form of a message sent to a legitimate user of the site. Inside the message is a malicious script which then infects the system and provides access to the hacker. These types of attacks can be addressed using techniques including escaping, validating the input, and sanitizing anything a user inputs into the system."

An interviewer will ask this question, which, of course, is technical in nature to both test your knowledge and to ensure that you know how to combat this type of attack. As a seasoned ICT administrator, you should be able to answer this question easily with both the definition of the term and a description of how you would defend against it. Since you won't know the technical expertise of the interviewer, keep your answer at a high level. They will ask follow-up questions if they need more information from you.

"Cross-site scripting or XSS is a type of security vulnerability that is most commonly found in web applications. It enables attackers to inject a malicious script into the web pages. This allows attackers to bypass common security measures. The best way to combat XSS attacks is to sanitize any input from the users."
