Vulnerability Mitigation for TLS 1.0 and Weak Ciphers

[LostBoY]

Hello,

I need  instructions to mitigate the following two vulnerabilities from our Gateways : 

1) Enable Support for TLS 1.1 and TLS 1.2 , and disable TLS  1.0

2) Removal of Weak Ciphers

We are using a VSX Cluster environment with R80.10

Also, what could be the after effects after removing these vulnerabilities on the existing production environment.

Please suggest.

Thanks
