NWebSec for securing HTTP headers of ASP.Net web applications

NWebSec is a library, that I am familiar and have used in some web applications over the past 3 – 4 years.

Modern web browsers support several HTTP headers for security related purposes. For example, not to cache content, always require HTTPS etc… Most, if not all of these headers can be set at the webserver level instead of at the application level. There are various guides and blog posts for doing the same on HTTP servers.

This blog post is about using NWebSec for setting these headers in ASP.Net web applications. I won’t go over the entire list but I would mention few.

Redirect Validation is one of the OWASP top 10 risks and should happen at the application level. UseRedirectValidation() method validates the redirects and can be configured. – https://docs.nwebsec.com/en/latest/nwebsec/Redirect-validation.html

Configure the X-Frame-Options either at the application level or at the web server level, unless you have a need for your websites to be displayed in iframes of other websites.

Always use https by using the Content Security Policy, Strict Transport Security, Upgrade Insecure Requests.

Apart from these use SecureCookies – https://owasp.org/www-community/controls/SecureCookieAttribute

I am hoping this blog post helps someone.
