Detect Port Scanning and Network Flooding attacks

Network Flooding is an attack on network resources of an organization (such as web servers). This attack consists of sending a large number of requests to overload the bandwidth of network resources. When this happens, users are unable to access the network resources of the organization.

A Port Scanning attack consists of scanning UDP ports, TCP ports, and network services on the computer. This attack allows the attacker to identify the degree of vulnerability of the computer before conducting more dangerous types of network attacks. Port Scanning also enables the attacker to identify the operating system on the computer and select the appropriate network attacks for this operating system.

If this check box is selected, Kaspersky Endpoint Security monitors network traffic to detect these attacks. When an attack is detected, the application filters and blocks the traffic associated with the attack. This way, if a Network Flooding attack is launched against the computer, the application reduces the load on the resource being attacked. If a Port Scanning attack is launched against the computer, Kaspersky Endpoint Security prevents data leaks on the computer.

You can disable detection of these types of attacks in case some of your allowed applications perform operations that are typical for these types of attacks. This will help avoid false alarms.

Add the attacking computer to the list of blocked computers for N minutes

If the check box is selected, the Network Threat Protection component adds the attacking computer to the blocked list. This means that the Network Threat Protection component blocks the network connection with the attacking computer after the first network attack attempt for the specified amount of time. This block automatically protects the user's computer against possible future network attacks from the same address.

You can view the block list in the Network Monitor tool window.

Kaspersky Endpoint Security clears the block list when the application is restarted and when the Network Threat Protection settings are changed.

Exclusions

The list contains IP addresses from which Network Threat Protection does not block network attacks.

Kaspersky Endpoint Security does not log information on network attacks from the IP addresses that are in the list of exclusions.

Protection against MAC spoofing

A MAC spoofing attack consists of changing the MAC address of a network device (network card). As a result, an attacker can redirect data sent to a device to another device and gain access to this data. Kaspersky Endpoint Security lets you block MAC Spoofing attacks and receive notifications about the attacks.
