==Certificate Recommendations and Guidance==
In support of the HTTPS Everywhere initiative, a [[Media:Recommendations for TLS Server Certificates.pdf|recommendations document]] was developed for the purpose of identifying the minimum requirements for TLS server certificate type and content, issuing CA conformance and website responsibilities that apply to all externally facing GC websites. This effort was led by TBS OCIO in close collaboration with members of the HTTPS working group including CRA, CSE, ESDC and SSC.

Per the [[Media:Recommendations for TLS Server Certificates.pdf|Recommendations for TLS Server Certificates]] [PDF], “care must be exercised when using multi-domain and wildcard certificates to ensure collateral damage is minimized in the event of private key compromise. Copying the same private key to multiple web servers is strongly discouraged unless appropriate risk mitigation measures are in place such as using CSE approved Hardware Security Modules to protect the private key.”
