4.1. Kaspersky Anti-Hacker 

Operating Principles 

Kaspersky Anti-Hacker protects your computer from network attacks and 
preserves your confidential data. To do this, Kaspersky Anti-Hacker monitors all 
network operations on your computer. There are two types of network operation: 

•  Operations on the application level (high-level). At this level, Kaspersky 

Anti-Hacker analyses activity of network applications, including web 
browsers, mail programs, file transferring programs and others. 

•  Operations on the packet level (low-level). At this level, Kaspersky Anti-

Hacker analyses data packet sent/received by your netcard or modem. 

You work with Kaspersky Anti-Hacker by creating special filtering rules for 
network operations. Some filtering is performed automatically by the Intrusion 
Detection System, which can detect port scanning, DoS attacks, etc., and can 
then block the assaulter. In addition, you can define your own filtering rules to 
reinforce protection of your machine. 

For every type of network operation there are separate lists of Kaspersky Anti-
Hacker rules. 

•  Application rules. Here you can select the required application and allow 

an activity that is compliant with the application type. You can define any 
number of rules for every application, as required. If any network activity 
not meeting conditions of the rule is detected on your machine, the pro-
