Default Global Policies for Security Protocols and Cipher Suites

Global acceptance and proposal policies enable certain security protocols and cipher suites by default.

Security-related settings are provided in Horizon LDAP.

Default Security Protocols	Default Cipher Suites	Default Signature Schemes
`TLS 1.2`	TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 TLS_RSA_WITH_AES_128_CBC_SHA256 TLS_RSA_WITH_AES_256_CBC_SHA256	rsa_pss_rsae_sha512 rsa_pss_rsae_sha384 rsa_pss_rsae_sha256 rsa_pss_pss_sha512 rsa_pss_pss_sha384 rsa_pss_pss_sha256 rsa_pkcs1_sha512 rsa_pkcs1_sha384 rsa_pkcs1_sha256 rsa_pkcs1_sha1 ecdsa_secp521r1_sha512 ecdsa_secp384r1_sha384 ecdsa_secp256r1_sha256
