Cookie dan sesi for Microsoft IIS

high5 checks

Session cookies are the keys to an account. Missing attributes turn a single XSS bug into full account takeover.

What Microsoft IIS must have

  • Secure attribute on every cookie
  • HttpOnly on session cookies
  • SameSite=Lax or Strict on session cookies
  • No session identifier in URLs or localStorage
  • Session rotation after login and logout invalidation

How to fix it

  1. 1Set cookie attributes at the framework level so every cookie inherits them
  2. 2Move tokens out of localStorage to HttpOnly cookies

Microsoft IIS context

Windows web server hosting ASP.NET and static content.

Disable WebDAV if unused, remove ASP.NET version headers and block trace.axd.
