You can use executable files from a selected folder as a standard of executable files that you want to allow or block in your organization. On the basis of executable files from the selected folder, you can create an application category and use it in the Application Control component configuration.
To create a category that includes executable files from the selected folder:
In the main menu, go to Operations → Third-party applications → Application categories.
The page with a list of categories is displayed.
Click the Add button.
The New category wizard starts. Proceed through the wizard by using the Next button.
On the Select category creation method step, specify the category name and select the Category that includes executable files from a specific folder. Executable files of applications copied to the specified folder are automatically processed and their metrics are added to the category option.
Specify the folder whose executable files will be used to create the category.
The application category includes dynamic-link libraries (files in DLL format), and the Application Control component logs the actions of such libraries running in the system. Including DLL files in the category may lower the performance of Kaspersky Security Center.
The application category includes data on scripts, and scripts are not blocked by Web Threat Protection. Including the script data in the category may lower the performance of Kaspersky Security Center.
By default, this check box is cleared.
Hash value computing algorithm: Calculate SHA256 for files in this category (supported by Kaspersky Endpoint Security 10 Service Pack 2 for Windows and later versions) / Calculate MD5 for files in this category (supported by versions earlier than Kaspersky Endpoint Security 10 Service Pack 2 for Windows)
Depending on the version of the security application installed on devices on your network, you should select an algorithm for hash value computing by Kaspersky Security Center Linux for files in this category. Information about computed hash values is stored in the Administration Server database. Storage of hash values does not increase the database size significantly.
SHA256 is a cryptographic hash function: no vulnerabilities have been found in its algorithm, and so it is considered the most reliable cryptographic function nowadays. Kaspersky Endpoint Security for Linux supports SHA256 computing.
Select either of the options of hash value computing by Kaspersky Security Center Linux for files in the category:
If all instances of security applications installed on your network are Kaspersky Endpoint Security for Linux, select the SHA256 check box.
Select the MD5 hash check box only if you use Kaspersky Endpoint Security for Windows. Kaspersky Endpoint Security for Linux does not support the MD5 hash function.
The Calculate SHA256 for files in this category (supported by Kaspersky Endpoint Security 10 Service Pack 2 for Windows and any later versions) check box is selected by default.
The Calculate MD5 for files in this category (supported by versions earlier than Kaspersky Endpoint Security 10 Service Pack 2 for Windows) is cleared by default.
If this option is enabled, the application regularly checks the folder of category content addition for changes. You can specify the frequency of checks (in hours) in the entry field next to the check box. By default, the time interval between forced checks is 24 hours.
If this option is disabled, the application does not force any checks of the folder. The Server attempts to access files if they have been modified, added, or deleted.
By default, this option is disabled.
When the wizard finishes, the category of executable files is created. It is displayed in the list of categories. You can use the category at Application Control configuration.
