An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
Cross-site scripting, commonly referred to as XSS, is a type of security vulnerability found in web applications. This vulnerability allows attackers to inject malicious scripts into content from otherwise trusted websites.
The scripts, often written in JavaScript, are executed in a user's web browser, which is why they are typically associated with client-side vulnerabilities.
Let's break down the options provided:
PHP : PHP is a server-side scripting language used to develop web applications. While it can be used to help protect against XSS by properly sanitizing and validating input data, it is not itself the typical medium for XSS attacks.
Cookies : Cookies are small pieces of data stored by a web browser at the request of a web server. They can be manipulated in an XSS attack but are not the direct means through which XSS vulnerabilities are executed.
SQL Queries : SQL queries are used to interact with databases. While they can be involved in a different type of attack known as SQL Injection, they are not directly related to XSS vulnerabilities.
JavaScript : Scripts typically executed in a user's browser during an XSS attack are written in JavaScript. JavaScript is the language that most web vulnerabilities (like XSS) exploit to manipulate web pages, steal cookies, or perform other malicious actions.
Correct Option :
JavaScript
JavaScript is the correct answer, as cross-site scripting vulnerabilities execute scripts in a user's browser using this language.
To prevent XSS attacks, web developers should implement security measures such as input validation, content security policies, and sanitizing user inputs to ensure unwanted scripts are not executed.
Approximately 2.81 × 1 0 21 electrons flow through the device that delivers a current of 15.0 A for 30 seconds. This is calculated by determining the total charge delivered and then dividing it by the charge of a single electron. The calculations show how to connect the current, time, and electric charge to find the number of electrons.
