During the operation of Kaspersky Endpoint Security, the Web Control, Mail Threat Protection and Web Threat Protection components monitor data streams that are transmitted via specific protocols and that pass through specific open TCP and UDP ports on user computer. For example, the Mail Threat Protection component analyzes information transmitted via SMTP, while the Web Threat Protection component analyzes information transmitted via HTTP and FTP.
Kaspersky Endpoint Security divides TCP and UDP ports of the operating system into several groups, depending on the likelihood of their being compromised. The network ports that are dedicated for vulnerable services are recommended to be monitored more thoroughly, because the probability that they are attacked is higher. If you use non-standard services that rely on non-standard network ports, these network ports may also be targeted by an attacking computer. You can specify a list of network ports and a list of applications that request network access. These ports and applications then receive special attention from the Mail Threat Protection and Web Threat Protection components during network traffic monitoring.
