Deactivate unnecessary ciphers

Hello,

It it possible to deactivate from a FortiGate the unnecessary ciphers? For example, if the preferred ciphers are AES-256, AES-192, is it possible to deactivate all the others?

 

This requirements is coming from an external consultant who did an audit to our FortiGates and suggested this as security hardening.

 

Thanks

Andreas

config vpn ssl settings   set algorithm <cipher_suite> end

 

where one of the following variables replaces <cipher_suite>:   low Use any cipher suite; AES, 3DES, RC4, or DES.   medium Use a 128-bit or greater cipher suite; AES, 3DES, or RC4.   high Use a ciper suite grather than 128 bits; AES or 3DES.
