Secure front-end profile
In addition to a default front-end and a default back-end profile, a new default secure front-end profile is available from release 12.1. The settings required for an A+ rating (as of May 2018) from Qualys SSL Labs are preloaded into this profile. Earlier, you had to explicitly set each of the parameters required for an A+ rating on an SSL front-end profile or an SSL virtual server. Now you can bind the ns_default_ssl_profile_secure_frontend profile to your SSL virtual server and the required parameters are automatically set on your SSL virtual server.
Note:
The secure front-end profile is not editable.
When you enable the default profile, the default front-end profile is automatically bound to all the SSL virtual servers. To get an A+ rating, you must explicitly bind the ns_default_ssl_profile_secure_frontend profile and also bind an SHA2/SHA256 server certificate to your SSL virtual server.
Secure front-end profile parameters
The parameters with their default settings are listed here:
SSLv3: DISABLED TLSv1.0: DISABLED TLSv1.1: DISABLED TLSv1.2: ENABLED TLSv1.3: DISABLED Deny SSL Renegotiation: NONSECURE HSTS: ENABLED HSTS IncludeSubDomains: YES HSTS Max-Age: 15552000 Cipher Name: SECURE Priority :1 Secure cipher alias
A new secure cipher alias is added and bound to the secure front-end profile. To list the ciphers that are part of this alias, at the command prompt type: show cipher SECURE
show cipher SECURE 1) Cipher Name: TLS1.2-ECDHE-RSA-AES256-GCM-SHA384 Priority : 1 Description: TLSv1.2 Kx=ECC-DHE Au=RSA Enc=AES-GCM(256) Mac=AEAD HexCode=0xc030 2) Cipher Name: TLS1.2-ECDHE-RSA-AES128-GCM-SHA256 Priority : 2 Description: TLSv1.2 Kx=ECC-DHE Au=RSA Enc=AES-GCM(128) Mac=AEAD HexCode=0xc02f 3) Cipher Name: TLS1.2-ECDHE-ECDSA-AES256-GCM-SHA384 Priority : 3 Description: TLSv1.2 Kx=ECC-DHE Au=ECDSA Enc=AES-GCM(256) Mac=AEAD HexCode=0xc02c 4) Cipher Name: TLS1.2-ECDHE-ECDSA-AES128-GCM-SHA256 Priority : 4 Description: TLSv1.2 Kx=ECC-DHE Au=ECDSA Enc=AES-GCM(128) Mac=AEAD HexCode=0xc02b Done 配置
Perform the following steps:
- Add a load balancing virtual server of type SSL.
- Bind a SHA2/SHA256 certificate.
- Enable the default profile.
- Bind the secure front-end profile to the SSL virtual server.
