I need to enable and use TLS 1.2 only instead of 1.0 or 1.1, for one specific published server.
my BIG-IP version is 12.0 VE.
this output may help you
ssl-ciphersuite DEFAULT:!aNULL:!eNULL:!LOW:!RC4:!MD5:!EXP
please your kind assistance.
Thanks,
Osama
Hi mahjoub,
Yes, you can configure it through GUI.
- You need to create new client SSL Profile - Goto Local Traffic > Profiles > SSL > Client and create new profile.
- Under Advance setting, select Custom Cipher Suits to block required TLS/SSL versions. Appending "!" before any TLS/SSL, encryption parameter in cipher string blocks that particular version.
- There is one more way to configure same. Under client SSL Advance Configuration, select Options List in Options sections. Then You will get options to enable/disable particular TLS/SSL version. e.g. for blocking TLS1.1, you can enable No TLS1.1 in this section to it will block TLS1.1.
This way you can achieve your requirement. You can refer below F5 articles for more details.
