This section explains how to Configure Stronger SSL Cipher.


SSL ciphers are defined by the Templates > Security > SSL/TLS Profile. Within a profile, List view and string view are the two modes for configuring ciphers.

For more information, see Apple’s App Transport Security topic in the VMware NSX Advanced Load BalancerConfiguration Guide.

SSL Rating

Modifying or reordering the list will alter the associated SSL rating in the top-right corner of the SSL/ TLS Profile edit window. This provides insight into the encryption performance, security, and client compatibility of the selected ciphers. This ranking is only made against the validated ciphers from the List View mode.

List View

The default cipher list view shows common ciphers in order of priority. Enable or deactivate ciphers using the check box, and reorder them using the up/ down arrows or drag and drop. List view provides a static list of validated ciphers. If alternate ciphers not listed are required, consider using String View. The ciphers included in this list are considered reasonably strong. If a cipher is later deemed to be insecure or less secure, its security score rating will drop to indicate it has fallen out of favor.

String View

The second cipher configuration mode allows accepted ciphers to be added as a string, similar to the OpenSSL syntax for viewing and setting ciphers. For this mode, NSX Advanced Load Balancer accepts all TLS 1.0 - 1.2, and Elliptic Curve ciphers from In this mode, the administrator must determine if the enabled ciphers are secure. You can set strong security by employing a known cipher suite, such as HIGH.
