Why does Telusys require a fixed or static IP address to utilize the FTP service?
Telusys operates a closed secure network. Despite the fact that we will be supporting FTP, we maintain that there is risk involved in its usage. After analyzing security logs on our systems, it is clear that hackers actively probe for vulnerable FTP ports. The FTP user name and password is the first layer of protection for our clients utilizing FTP, because this information is sent through the Internet unencrypted, it can also fall into the wrong hands. Addressing this possibility we developed a second layer of security to only allow incoming FTP connections through our firewalls to specific Web servers from authorized computers.
