About Network Protection

During the operation of Kaspersky Endpoint Security, such components as Mail Anti-Virus, Web Anti-Virus, and IM Anti-Virus monitor data streams that are transmitted via specific protocols and that pass through specific open TCP and UDP ports on your computer. For example, Mail Anti-Virus scans data that is transmitted via SMTP, while Web Anti-Virus scans data that is 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. Some network ports are reserved for services that may be vulnerable. You are advised to monitor these ports more thoroughly, because the likelihood that they are attacked is greater. 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 Anti-Virus, Web Anti-Virus, and IM Anti-Virus components as they monitor network traffic.
