Fundamentals of Secure Software - CSP (Content Security Policy)

The video tutorial explains Content Security Policy (CSP), a security feature that helps detect and mitigate attacks like cross-site scripting. It covers how to enable CSP, its compatibility with browsers, and how it mitigates script execution vulnerabilities. The tutorial provides guidelines for writing CSP policies using directives, explains various directives and their functions, and introduces advanced directives in CSP 2.0. An example CSP policy is presented to demonstrate its impact on security.

What is the primary purpose of Content Security Policy (CSP)?

• To enhance website aesthetics

• To improve website loading speed

• To increase website traffic

• To detect and mitigate certain types of attacks

How does CSP help in mitigating cross-site scripting attacks?

• By specifying whitelisted domains for script execution

• By allowing all scripts to run

• By disabling all browser functionalities

• By blocking all external resources

What is a key component of writing a CSP?

• Enabling all JavaScript functions

• Blocking all images

• Only images

• All resources without specific directives

• Only styles

• Only scripts

What is the effect of a properly configured CSP policy?

• It increases website loading time

• It blocks all website functionalities

• It limits the impact of vulnerabilities

• It allows all scripts to run

In the given CSP example, what is allowed from the same origin?
