NimbostratusSSL Profile Cipher
Hi all i need to make sure that my SSL Client profile uses TLS1.2 without using DES Cipher . what i have done is to change the Chiper in SSL Profile from DEFAULT to TLS1_2:!DES just making sure that ...
what i want to make sure that when i write in the cipher TLS1_2:!DES:!3DES will use only TLS1.2 protcol without DES or 3DES ciphers
yes but i suggest you check tmm --clientciphers, so you will know what exactly cipher suites you get.
for example, the following is output from 13.1.0.1. although, only tls 1.2 without des or 3des but it also includes rc4.

thats mean that it as i didnt SSL profile at all and it will accept any certificate or what.
if i do not misremember, ignore means big-ip will not request client certificate from client (server certificate is already presented to client).

additionally, you may also consider disabling protocol (e.g. ssl 3.0, tls 1.0, tls 1.1) using clientssl profile's options.

AhmedGalal219_3thanks this was very helpful i did prevent RC4 too and i will convert all client certificate option in profiles to require cuz i didnt know at the beginig that ignore is the default option and it doesnt inforce and validate client certificate .
