Kaspersky Small Office Security 2 6. In the lower part of the Settings window click the Apply button. Placing applications into groups At the first startup of an application on the computer, the Application Control component verifies its safety and searches the internal database of known applications for a matching entry, and then sends a request to the Kaspersky Security Network 1 database or having a digital signature 2 . After search Application Control places the application into one of the following trusted groups: ► Trusted. Trusted applications are applications with digital signatures of trusted vendors and applications signatures of those are included to the trusted applications database. Applications of that group are allowed to perform any network activity. Activities of such applications are monitored by Proactive Defense and File Anti-Virus. ► Low Restricted. Low restricted applications are applications which are without digital signatures of trusted vendors and which are not included to the trusted applications database. Nevertheless, the low risk rating 3 . is assigned to such applications. Applications of that group are allowed to perform some operations, to manage the system, hidden access to the network. Most operations require user authorization. ► High Restricted. High restricted applications are applications without digital signatures and which are not included to the trusted applications database. The high risk rating is assigned to such applications. Applications of this group require user authorization for most activities in the system; some actions, however, are restricted for these applications. 1 Kaspersky Security Network is a system which allows to get information about files opened by the user on the computer and thus tracks malicious objects and their spreading channels. 2 Digital signature is an electronic security mark which carries the information about the software vendor and shows if the software was changed after the signing (i.e. after release). If software is signed by its vendor and the signature authenticity is verified by the certificate center, then you can be sure that the software is authentic and was not. 16 Risk rating is an indicator of the application danger for the system. The risk rating is calculated based on definite criteria. 3 | 28
Kaspersky Small Office Security 2 ► Untrusted. Untrusted applications are applications without digital signatures and which are not included to the trusted applications database. Very high risk rating is assigned to such applications. Application Control blocks any activity of such applications. To disable the automatic inclusion of applications into the Trusted group, perform the following actions: 1. In the left part of the Settings window select the Security Zone component. 2. In the right part of the window in the Trusted applications section uncheck the boxes Applications with digital signature and Trusted in Kaspersky Security Network database. 3. In the Settings window click the Apply button. If an application record is not included into Kaspersky Security Network database and the application does not have a digital signature, then KSOS 2 uses the heuristic analysis 4 . The analysis helps defining the threat rating of the application based on which it is included into a group. To use the heuristic analysis for distributing unknown applications by groups, perform the following actions: 1. In the left part of the Settings window select the Security Zone component. 2. In the right part of the window in the Trusted applications section select the Use heuristic analyzer to define the group option. 3. Click the Apply button in the right bottom corner of the window. 4 Heuristic analysis is analysis of objects activity in the system. If the activity is typical of malicious objects in this case the object under analysis will be defined as suspicious or malicious. Analysis of the object activity allows to detect a virus even if it has not been defined by virus analysts. 4 | 28
