One of my consultants mentioned to me today that he was able to login to the Expressway-E server from outside the company via port 443. I've been digging through the documentation and searching for best practices, but I haven't found anything on how I might better secure against that potential vulnerability. Can anyone point me in the right direction? I feel like this is something simple that I am just overlooking.</P><P>&nbsp;</P><P>Thanks,</P><P>Tim</P> Tue, 23 Mar 2021 13:39:31 GMT https://community.cisco.com/t5/unified-communications-infrastructure/expressway-e-permits-external-logins-via-port-443/m-p/4312268#M166341 tim.martin14 2021-03-23T13:39:31Z https://community.cisco.com/t5/unified-communications-infrastructure/expressway-e-permits-external-logins-via-port-443/m-p/4312286#M166342 <P>Hi,</P> <P>In this case, configure firewall to block incoming traffic to port 443 for Expressway-E server IP Address.</P> <P>&nbsp;</P> <P>&nbsp;</P> Tue, 23 Mar 2021 13:59:18 GMT https://community.cisco.com/t5/unified-communications-infrastructure/expressway-e-permits-external-logins-via-port-443/m-p/4312286#M166342 Vaijanath Sonvane 2021-03-23T13:59:18Z
