Kaspersky Security Cloud protects your computer against network attacks.
A network attack is an attempt to break into the operating system of a remote computer. Criminals attempt network attacks to establish control over the operating system, cause denial of service in the operating system, or access sensitive information. To achieve these goals, criminals either carry out direct attacks, such as port scanning and brute force attacks, or use malware installed on the computer being attacked.
Network attacks can be divided into the following types:
The main types of DoS attacks are:
This type of network attack is used when the intruder wants to obtain confidential data (such as bank card numbers or passwords) from a remote computer or secretly use the remote computer for his or her own purposes (such as attacking other computers from this computer).
Important: If you disable Network Attack Blocker, it will not be re-enabled automatically when Kaspersky Security Cloud starts again or after the operating system restarts. You have to re-enable Network Attack Blocker manually.
When the application detects dangerous network activity, Kaspersky Security Cloud automatically adds the IP address of the attacking computer to the list of blocked computers, unless the attacking computer is in the list of trusted computers.
You can create and edit the list of trusted computers. Kaspersky Security Cloud doesn't block the IP addresses of these computers automatically even after dangerous network activity is detected from them.
When a network attack is detected, Kaspersky Security Cloud logs information about the attack in a report.
Note: If the Network Attack Blocker component stops running with an error, you can view the report and try to restart the component. If the problem is not solved, you can contact Kaspersky Technical Support.Page top
