==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.

===Enterprise Certificate Management===
Recently the National Institute of Standards and Technology released [https://www.nccoe.nist.gov/projects/building-blocks/tls-server-certificate-management Special Publication 1800-16 Securing Web Transactions: TLS Server Certificate Management] for public comment. This draft practice guide provides additional information for enterprises that rely on Transport Layer Security (TLS) to secure both customer-facing and internal applications, so they can better manage TLS server certificates by:
* Defining operational and security policies; identifying roles and responsibilities
* Establishing comprehensive certificate inventories and ownership tracking
* Conducting continuous monitoring of certificate operational and security status
* Automating certificate management to minimize human error and maximize efficiency on a large scale
* Enabling rapid migration to new certificates and keys when cryptographic mechanisms are found to be weak, compromised or vulnerable

* In the absence of HSMs, risk mitigation measures should include effective monitoring and auditing of the system so that private key compromise can be detected as early as possible followed immediately with revocation of the associated server certificate.

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.”
