What type of policy serves to enhance security against web-based attacks?

The Content Security Policy (CSP) is an essential security feature that helps protect web applications from various types of attacks, particularly cross-site scripting (XSS) and data injection attacks. CSP allows web developers to specify which sources of content are considered safe to load on a web page. By implementing a CSP, a website can control resources such as scripts, styles, images, and other types of content that can be executed or rendered in the browser.

When a CSP is enforced, it can block the execution of malicious scripts that may be injected into the webpage, thus significantly mitigating the risk of XSS vulnerabilities. For instance, if a website defines a CSP that restricts the execution of scripts only to those that originate from trusted domains, any unauthorized scripts trying to run from other sources will be blocked by the browser.

This focus on whitelisting specific content sources based on trusted origins plays a critical role in securing web applications against malicious attacks that can compromise user data and interactions.

In contrast, the other policies mentioned do tackle security concerns but are geared towards different aspects. Data Loss Prevention focuses on safeguarding sensitive data from unauthorized access and transmission. Network Security Policy generally outlines protocols and rules for securing network infrastructure, and Access Control Policy is centered around defining who can
