1. Cross-Site Scripting (XSS):

Q1: What is CSP (Content Security Policy), and how does it protect against XSS attacks?
A1: CSP controls the CSP header to protect against XSS, file injection, and code execution attacks by specifying trusted sources for various content types.

Q2: What is the recommended setting for CSP?
A2: Enable "Send HTTP response header" and configure a CSP policy.

Q3: Why should I enable legacy vendor-prefixed CSP headers?
A3: Enabling legacy vendor-prefixed CSP headers ensures compatibility with older browsers.

Q4: When should I use the "Report Only" option in CSP?
A4: The "Report Only" option allows testing CSP policies without blocking resources. It's useful for testing your CSP policy.

Q5: What is the purpose of the "X-Content-Security-Policy" header?
A5: It's a standard CSP header supported by major browsers, helping protect against XSS attacks.

2. Directives:

Q6: What is the purpose of the "default-src" directive in CSP?
A6: The "default-src" directive specifies the default policy for all content types (except frame-ancestors). The default is "self," meaning content must come from the same origin.

Q7: How can I prevent malicious JavaScript loading using CSP?
A7: Use the "script-src" directive to specify trustworthy sources for <script> elements.

Q8: What is the "report-uri" directive used for in CSP?
A8: The "report-uri" directive specifies a URL for reporting CSP violations, helping you track and analyze policy breaches.

3. X-XSS Protection header:

Q9: What does the "X-XSS-Protection" header do, and what's the recommended setting?
A9: The "X-XSS-Protection" header blocks attempts to inject malicious JavaScript into a page. The recommended setting is "1; mode=block."

4. Cross-site Request Forgery (CSRF):

Q10: How does the "HTTP Origin" setting protect against CSRF attacks?
A10: The "HTTP Origin" setting verifies the request origin to protect against CSRF attacks.

5. Click Jacking:

Q11: How does the "X-Frame-Options" header prevent clickjacking attacks?
A11: The "X-Frame-Options" header prevents clickjacking by controlling frame rendering. Setting it to "DENY" prevents embedding your site in frames on other websites.

Q12: What additional protection can I enable to guard against various attacks, including XSS?
A12: Enabling JavaScript + CSS + Noscript protection and defining appropriate policies adds security headers for protection.

6. SSL/TLS:

Q13: What is HTTP Strict Transport Security (HSTS), and why should I use it?
A13: HSTS enforces HTTPS usage for a specified duration and includes subdomains. It's essential for secure communication. Configure it with your desired duration and the "includeSubDomains" directive.

Q14: What is the purpose of the "Expect-CT" setting?
A14: "Expect-CT" mitigates certificate transparency (CT) bypass attacks. It should be enabled and tested for functionality.

7. Feature Policy:

Q15: How does Feature Policy help protect against XSS and clickjacking?
A15: Feature Policy controls how features are enabled in a web page, providing protection against various attacks. You should enable and configure it as needed.

8. Miscellaneous:

Q16: What is the "Referrer-Policy" setting, and how does it protect against clickjacking and other attacks?
A16: "Referrer-Policy" controls how referrer information is sent with HTTP requests to protect against clickjacking and other attacks. The choice should be based on your website's needs and concerns.

Q17: When should I disable autocomplete on login and registration forms?
