I understand that Guardian uses FTP do download items through Guardian links or KBA article links (MS security updates, hotfixes etc...)
What communications ports are used to download via FTP?
What protocol is used to upload the Sure Service Registration file back to Guardian? Is this an FTP upload? What ports are required for this communication to work?
What is the timing for converting Guardian to SFTP (secure FTP)?
My corporate IT is tightening firewall rules across the board. I had to request a firewall rule deviation to allow FTP traffic from Guardian to allow download traffic for updates and hotfixes. This is only a temporary fix with an expiration date.
