Default Global Policies for Security Protocols and Cipher Suites

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

Security-related settings are provided in Horizon LDAP under the object path cn=common,ou=global,ou=properties,dc=vdi,dc=horizon,dc=internal.

Default Security Protocols	Default Cipher Suites	Default Signature Schemes
`TLS 1.3` Note: This is the preferred protocol starting with the Horizon 2312.1 release.	TLS_AES_128_GCM_SHA256 TLS_AES_256_GCM_SHA384 TLS_CHACHA20_POLY1305_SHA256 (2503 and later)	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
