Understanding Content Security Policy (CSP)

TYPO3

Description

Content Security Policy (CSP) is a security standard introduced to prevent cross-site scripting (XSS), clickjacking and other code injection attacks resulting of malicious content being executed in the trusted web page context.

Goals

• I know what Content Security Policy (CSP) is and how it serves as a tool to prevent Cross-Site Scripting (XSS) and data injection attacks.
• I understand that CSP rules can block certain content on my website, particularly controlling inline code and external contents like iframes.
• I can formulate specific policies to determine which scripts, images, stylesheets, and other resources are allowed, enhancing my website's security.
• I am aware of the mechanisms for monitoring CSP violations and can create reports to identify and fix possible security breaches.
• I understand how Content Security Policy can be combined with other security practices to create a robust defense system.
• I recognize that CSP is flexible and can be customized to meet the specific needs and requirements of my website without affecting functionality or user experience.
