When Kaspersky Security is running, the File Anti-Virus component of Light Agent for Windows, the Mail Anti-Virus component and the Web Anti-Virus component monitor data streams that are transmitted over specific protocols and that pass through specific open TCP and UDP ports on the protected virtual machine. 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 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 and Web Anti-Virus components as they monitor network traffic.
You can perform the following actions to configure the settings of network traffic monitoring:
