Fundamentals of Security Headers in Web Application Security MCQs

HTTP security headers add an extra layer of security by controlling browser behavior.

HTTP security headers contribute to preventing or mitigating security threats and vulnerabilities in web applications.

HSTS enforces the use of secure, encrypted connections (HTTPS) by instructing browsers.

X-Content-Type-Options prevents browsers from interpreting files as a different MIME type, enhancing security.

Referrer-Policy controls how much information is included in the Referer header, contributing to security.

CSP defines a set of rules to control the sources of content that browsers are allowed to load, contributing to security.

HPKP associates a set of public keys with a web server to prevent man-in-the-middle attacks, enhancing security.

Expect-CT instructs browsers to enforce certificate transparency requirements for the site's SSL/TLS certificates, enhancing security.

Feature-Policy controls which browser features and APIs can be used by a web page, enhancing security.

Cache-Control controls how content is cached by browsers and intermediary caches, contributing to security.

The recommended method for configuring HTTP security headers is using server configurations or web application firewalls.

Web developers can use online tools or browser developer tools to inspect HTTP response headers for verification.

Content-Security-Policy-Report-Only provides a reporting-only mode for CSP violations without enforcing restrictions.

Careful planning and testing are important to ensure that security headers do not disrupt the normal functioning of the application.

The HTTP Header Sniffer tool can be useful in web security by analyzing and identifying the HTTP headers used by a web application.

X-Frame-Options prevents a web page from being displayed within an iframe, mitigating clickjacking attacks.

Cross-Origin-Embedder-Policy controls how a document is embedded across different origins, contributing to security.

The Server header should be minimized or omitted to avoid disclosing information about the server software and version.

HSTS may cause a delay in the initial page load for first-time visitors as it enforces the use of HTTPS.

Keeping security headers up-to-date is crucial to address emerging security threats and vulnerabilities in web applications.

X-Permitted-Cross-Domain-Policies controls how Flash and Adobe Acrobat can interact with a web application, contributing to security.

X-Content-Type-Options prevents browsers from interpreting files as a different MIME type than declared, mitigating MIME type sniffing attacks.

X-XSS-Protection enables or disables the browser's built-in cross-site scripting (XSS) filter, contributing to security.

X-Download-Options prevents the automatic execution of downloaded files in Internet Explorer, enhancing security.

X-Permitted-Cross-Domain-Policies controls how Flash and Adobe Acrobat can interact with a web application, contributing to security.

X-Frame-Options prevents a web page from being displayed within an iframe, mitigating clickjacking attacks.

Content-Security-Policy-Report-Only provides a reporting-only mode for CSP violations without enforcing restrictions.

The HTTP Header Security Scanner tool automatically scans and identifies security header configurations, benefiting web developers.

Feature-Policy controls which browser features and APIs can be used by a web page, contributing to security.

Cross-Origin-Opener-Policy controls how documents can be opened across different origins, contributing to security.
