Feb 12, 2010best practice for ssl ciphers
hi everyone
we've recently had a security audit and the report has recommended that we disable the following ciphers:
EXP-DES-CBC-SHA
EXP-RC2-CBC-MD5
EXP-RC4-MD5 ...

Feb 16, 2010If you disable a cipher in the client SSL profile, LTM won't offer it in the list of available ciphers in the server hello during the SSL handshake. There wouldn't be any negative impact if the client and LTM can agree on a cipher. The only problem arises if there isn't at least one cipher in the list of ciphers the client and LTM both support. In that case, the SSL handshake will fail.
So it's good to configure the limited ciphers on a test VIP and test with each OS/browser combination (or as many as you can) that your web app supports.
