Restrict BIGIQ to TLSv1.2 Only

I need to restrict BIGIQ to TLSv1.2 only. How do you go about doing this?

    Greetings, Just a quick search through this article:

    https://support.f5.com/csp/article/K17007

K17007: Restricting BIG-IQ user interface access to clients using high-encryption SSL ciphers and protocols

    Perhaps try:

    vi /etc/webd/webd.conf

remove-> ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
add----> ssl_protocols TLSv1.2;

bigstart restart webd
bigstart status webd

      Thanks I updated the following ssl protocols and the cipher and restarted the webd service.

       

      ssl_protocols TLSv1.2;

       

      ssl_ciphers DHE-RSA-AES128-GCM-SHA256;

       

      restart /sys service webd

       

      That fixed the issue

    Unfortunately even with the change it is still responding to TLS1.1 connections even though disabled.

    [admin@uklprlbiq01:Active:Standalone] ~  cat /etc/webd/webd.conf | grep ssl_protocols
        ssl_protocols TLSv1.2;

    Both Qualys and SSLPressure are both reporting this.
