set ssl_tls_ciphers
The set ssl_tls_ciphers
command allows you to enable or disable the SSL/TLS ciphers for APACHE and SAML services only. You can enable any specific cipher suite or all the cipher suites. The default cipher suites are enabled in a specific order. However, you can change this default order. Note that you cannot disable all the cipher suites. At least one cipher suite must be enabled.
The default cipher suites are enabled in the following order:
TLS_DHE_RSA_WITH_AES_128_GCM_SHA256
TLS_DHE_RSA_WITH_AES_256_GCM_SHA384
TLS_DHE_RSA_WITH_AES_128_CBC_SHA
TLS_DHE_RSA_WITH_AES_256_CBC_SHA
TLS_DHE_RSA_WITH_AES_128_CBC_SHA256
TLS_DHE_RSA_WITH_AES_256_CBC_SHA256
TLS_RSA_WITH_AES_128_GCM_SHA256
TLS_RSA_WITH_AES_128_CBC_SHA
TLS_RSA_WITH_AES_128_CBC_SHA256
TLS_RSA_WITH_3DES_EDE_CBC_SHA
TLS_RSA_WITH_AES_256_GCM_SHA384
TLS_RSA_WITH_AES_256_CBC_SHA
TLS_RSA_WITH_AES_256_CBC_SHA256
You can also enable the following cipher suites that are disabled by default:
TLS_DHE_DSS_WITH_AES_256_CBC_SHA
TLS_DH_RSA_WITH_3DES_EDE_CBC_SHA
TLS_DH_DSS_WITH_3DES_EDE_CBC_SHA
TLS_DHE_DSS_WITH_AES_128_CBC_SHA
TLS_RSA_WITH_RC4_128_SHATLS_DHE_DSS_WITH_AES_256_GCM_SHA384
TLS_DHE_DSS_WITH_AES_256_CBC_SHA256
TLS_DHE_DSS_WITH_AES_128_GCM_SHA256
TLS_DHE_DSS_WITH_AES_128_CBC_SHA256

You can use the show ssl_tls_ciphers
command to view the enabled SSL/TLS cipher suites. For information, see show ssl_tls_ciphers.
Syntax
set ssl_tls_ciphers enable suite_name [ position ]
set ssl_tls_ciphers disable position
set ssl_tls_ciphers enable_all
Argument | Description |
---|---|
| Enables the cipher suites. |
| Specifies the name of a particular cipher suite. |
| Enables all cipher suites. |
| Specifies the position of a cipher suite. |
| Disables the cipher suites. |
Examples
Enable all cipher suites
Infoblox > set ssl_tls_ciphers enable_all
All cipher suites were enabled
The following services need to be restarted manually: GUI
Enable a specific cipher suite
Infoblox > set ssl_tls_ciphers enable TLS_RSA_WITH_RC4_128_SHA 8
TLS_RSA_WITH_RC4_128_SHA was enabled
The following services need to be restarted manually: GUI
Disable a specific cipher suite
Infoblox > set ssl_tls_ciphers disable 8
TLS_RSA_WITH_RC4_128_SHA was disabled
The following services need to be restarted manually: GUI
Note
Starting from NIOS 9.0, the weak ciphers(RC4 and 3DES for APACHE) and (RC4 and 3DES, and DHE for SAML) are deprecated.
It is recommended to avoid enabling only the following ciphers, as this will affect the APACHE/SAML services.
RC4
TLS_RSA_WITH_RC4_128_SHA
3DES
TLS_RSA_WITH_3DES_EDE_CBC_SHA
TLS_DH_RSA_WITH_3DES_EDE_CBC_SHA
TLS_DH_DSS_WITH_3DES_EDE_CBC_SHA
DHE
TLS_DHE_RSA_WITH_AES_128_GCM_SHA256
TLS_DHE_RSA_WITH_AES_256_GCM_SHA384
TLS_DHE_RSA_WITH_AES_128_CBC_SHA
TLS_DHE_RSA_WITH_AES_256_CBC_SHA
TLS_DHE_RSA_WITH_AES_128_CBC_SHA256
TLS_DHE_RSA_WITH_AES_256_CBC_SHA256
TLS_DHE_DSS_WITH_AES_256_CBC_SHA
TLS_DHE_DSS_WITH_AES_128_CBC_SHA
TLS_DHE_DSS_WITH_AES_256_GCM_SHA384
TLS_DHE_DSS_WITH_AES_256_CBC_SHA256
