Details
Sets the SSL encryption algorithm to AES 256
Rationale:
Given that the network may be prone to sniffing, the HTTP access to the security appliance must be secured with SSL or TLS protocols. A secure encryption algorithm must be used.
Solution
For version 8.x, run the following command to enable AES 256 algorithm
HOSTNAME(CONFIG)# SSL ENCRYPTION AES256-SHA1
For version 9.x, run the following command to enable AES 256 algorithm
HOSTNAME(CONFIG)# SSL CIPHER TLSV1 CUSTOM AES256-SHA
