HTTP Response Headers Hardening for Exchange 2019 on Windows Server 2022
Category: Security Hardening Issue: Currently, Exchange 2019 running on Windows Server 2022 does not have strict HTTP response headers configured, leaving it potentially vulnerable to security threats such as MIME type sniffing, clickjacking, and cross-site scripting (XSS) attacks. Objective: Harden the security of Exchange 2019 web services by enabling the following HTTP response headers: X-Content-Type-Options: Prevents MIME type sniffing by forcing browsers to respect declared content types. X-Frame-Options: Prevents embedding of Exchange web pages in iframes to mitigate clickjacking attacks. X-XSS-Protection or Content-Security-Policy (CSP): Protects against reflected XSS attacks (X-XSS-Protection is deprecated, CSP is preferred). I have found this article; can anyone tell me if it applies to Exchange 2019 as well? HTTP Security Headers - Icewolf Blog Thank you
