Disabling Weak Ciphers
- Apr 17, 2023
I'm running v15.1.8 and the following matches.
DEFAULT:!TLSv1:!TLSv1_1:!DHE-RSA-AES256-SHA:!DHE-RSA-AES128-SHA:!DHE-RSA-AES256-GCM-SHA384:!DHE-RSA-AES128-GCM-SHA256:!DHE-RSA-AES256-SHA256:!DHE-RSA-AES128-SHA256I built it starting from DEFAULT:!TLSv1:!TLSv1_1 and excluding explicitly the suites from your comment that still were in the list. (I noticed there was 3 repetitions; also EDH-RSA-DES-CBC3-SHA did not show up in cipher rule so there was no need to specify it)
Hi CA_Valli
Sorry for the late reply. I've no issues in getting the supported cipher info via CLI (as provided above) but when I try to configure the below ciphers suites (Local Traffic -> Ciphers -> New Cipher Rule), I'm getting 'Cipher String is Invalid' error.
DEFAULT:!TLSv1:!TLSv1_1:!DHE-RSA-AES256-SHA:!DHE-RSA-AES128-SHA:!EDH-RSA-DES-CBC3-SHA:!DHE-RSA-AES256-SHA:!DHE-RSA-AES128-SHA:!EDH-RSA-DES-CBC3-SHA:!DHE-RSA-AES256-GCM-SHA384:!DHE-RSA-AES128-GCM-SHA256:!DHE-RSA-AES256-SHA256:!DHE-RSA-AES128-SHA256:!DHE-RSA-AES256-SHA:!DHE-RSA-AES128-SHA:!EDH-RSA-DES-CBC3-SHA
Am I missing something? Can you please advise?
