File Threat Protection

File Threat Protection prevents infection of the file system on the user device. File Threat Protection starts automatically with the default settings upon Kaspersky Embedded Systems Security start. It resides in the device operating memory and scans all files that are opened, saved, and launched.

File Threat Protection settings

Setting	Description
File Threat Protection enabled / disabled	This toggle button enables or disables File Threat Protection on all managed devices. The check toggle button is switched on by default.
File Threat Protection mode	In this drop-down list, you can select the File Threat Protection mode: Smart check (default value) – scan a file when there is an attempt to open it and scan it again when there is an attempt to close it if the file has been modified. If a process accesses and modifies a file multiple times in a certain period, the application scans the file again only when the process closes it for the last time. When opened – scan the file on an attempt to open it for reading, execution, or modification. When opened and modified – scan a file on an attempt to open it, and scan it again on an attempt to close it if the file has been modified.
First action	In this drop-down list, you can select the first action to be performed by the application on an infected object that has been detected: Disinfect the object. A copy of the infected object will be moved to the Storage. Remove the object. A copy of the infected object will be moved to the Storage. Perform recommended action on the object, based on data about the danger level of the threat detected in the file and about the possibility of disinfecting it (default value). Block access to the object.
Second action	In this drop-down list, you can select the second action to be performed by the application on an infected object, in case the first action is unsuccessful: Disinfect the object. A copy of the infected object will be moved to the Storage. Remove the object. A copy of the infected object will be moved to the Storage. Perform recommended action on the object, based on data about the danger level of the threat detected in the file and about the possibility of disinfecting it. Block access to the object (default value).
Scan scopes	Clicking the Configure scan scopes link opens the Scan scopes window.
Scan archives	This check box enables or disables scan of archives. If the check box is selected, the application scans the archives. To scan an archive, the application has to unpack it first, which may slow down scanning. You can reduce the archive scan duration by enabling and configuring the Skip object if scan takes longer than (sec) and Skip objects larger than (MB) settings. If the check box is cleared, the application does not scan the archives. This check box is cleared by default.
Scan SFX archives	This check box enables or disables self-extracting archive scans. Self-extracting archives are archives that contain an executable extraction module. If the check box is selected, the application scans self-extracting archives. If the check box is cleared, the application does not scan self-extracting archives. This check box is available if the Scan archives check box is unchecked. This check box is cleared by default.
Scan mail databases	This check box enables or disables scans of mail databases of Microsoft Outlook, Outlook Express, The Bat!, and other mail applications. If the check box is selected, the application scans mail database files. If the check box is cleared, the application does not scan mail database files. This check box is cleared by default.
Scan mail format files	This check box enables or disables scan of files of plain-text email messages. If this check box is selected, the application scans plain-text messages. If this check box is cleared, the application does not scan plain-text messages. This check box is cleared by default.
Skip text files	Temporary exclusion of files in text format from scans. If the checkbox is selected, Kaspersky Embedded Systems Security does not scan text files if they are reused by the same process for 10 minutes after the most recent scan. This setting makes it possible to optimize scans of application logs. If this check box is unselected, Kaspersky Embedded Systems Security scans text files. This check box is cleared by default.
Skip object if scan takes longer than (sec)	A field for specifying the maximum time to scan an object, in seconds. After the specified time, the application stops scanning the object. Available values: `0–9999`. If the value is set to `0`, the scan time is unlimited. The default value is `60`.
Skip objects larger than (MB)	The field for specifying the maximum size of an archive to scan, in megabytes. Available values: `0–999999`. If the value is set to `0`, the application scans objects of any size. The default value is `0`.
Log clean objects	This check box enables or disables logging of the ObjectProcessed event. If this check box is selected, the application logs the ObjectProcessed event for all scanned objects. If the check box is cleared, the application does not log the event. This check box is cleared by default.
Log unprocessed objects	This check box enables or disables logging of the ObjectNotProcessed event if a file cannot be processed during scan. If this check box is selected, the application logs the ObjectNotProcessed event. If the check box is cleared, the application does not log the event. This check box is cleared by default.
Log packed objects	This check box enables or disables logging of the PackedObjectDetected event for all packed objects that are detected. If this check box is selected, the application logs the PackedObjectDetected event. If the check box is cleared, the application does not log the event. This check box is cleared by default.
Use iChecker technology	This check box enables or disables scan of only new and modified since the last scan files. If the check box is selected, the application scans only new files or the files modified since the last scan. If the check box is cleared, the application scans the files regardless of the creation or modification date. The check box is selected by default.
Use heuristic analysis	This check box enables or disables heuristic analysis during an object scan. The check box is selected by default.
Heuristic analysis level	If the Use heuristic analysis check box is selected, you can select the heuristic analysis level in the drop-down list: Light is the least detailed scan with minimal system load. Medium is a medium scan with balanced system load. Deep is the most detailed scan with maximum system load. Recommended (default value) is the optimal level recommended by Kaspersky experts. It ensures an optimal combination of quality of protection and impact on the performance of protected servers.

Web address window

In this window, you can add a web address or a web address mask to the list of trusted web addresses.

You can add only HTTP/HTTPS web addresses to the list of trusted web addresses. You can use masks to specify web addresses. Masks are not supported to specify IP addresses.

When creating an address mask, use an asterisk (*) as a placeholder for one or more characters. If you enter the *abc* address mask, it is applied to all web resources that contain the "abc" sequence (for example, www.virus.com/download_virus/page_0-9abcdef.html). To include the asterisk in the address mask as a character, but not as a mask, enter the * character twice (for example, www.virus.com/**/page_0-9abcdef.html means www.virus.com/*/page_0-9abcdef.html).

Network Threat Protection

While the Network Threat Protection component is running, the application scans inbound network traffic for activity that is typical for network attacks. Network Threat Protection is started by default when the application starts.

The application receives the numbers of the TCP ports from the current application databases and scans incoming traffic for these ports. Upon detecting an attempt of a network attack that targets your device, the application blocks network activity from the attacking device and logs an event about the detected network activity.

To scan network traffic, the Network Threat Protection task receives port numbers from the application databases and accepts connections via all these ports. During the network scan process, it may look like an open port on the device, even if no application on the system is listening to this port. It is recommended to close unused ports by means of a firewall.

Kaspersky Security Network

To increase the protection of devices and user data, Kaspersky Embedded Systems Security can use Kaspersky's cloud-based knowledge base Kaspersky Security Network (KSN) to check the reputation of files, Internet resources, and software. The use of Kaspersky Security Network data ensures a faster response to various threats, high protection component performance, and fewer false positives.

Kaspersky Embedded Systems Security supports the following infrastructure solutions to work with Kaspersky's reputation databases:

Kaspersky Security Network (KSN) – A solution that receives information from Kaspersky and sends data about objects detected on user devices to Kaspersky for additional verification by Kaspersky analysts and to add to reputation and statistical databases.
Kaspersky Private Security Network (KPSN) – A solution that allows users of devices with Kaspersky Embedded Systems Security installed to access the reputation databases of Kaspersky, as well as other statistical data, without sending data to Kaspersky from their devices. KPSN is designed for corporate clients who can't use Kaspersky Security Network, for example, for the following reasons:
- No connection of local workplaces to the Internet
- Legal prohibition or corporate security restrictions on sending any data outside the country or the organization's local network

After changing the Kaspersky Embedded Systems Security license, submit the details of the new key to the service provider in order to be able to use KPSN. Otherwise, data exchange with KPSN will be impossible due to an authentication error.

Use of Kaspersky Security Network is voluntary. Kaspersky Embedded Systems Security suggests using KSN during installation. You can start or stop using KSN at any time.

There are two options for using KSN:

KSN with statistics sharing (extended KSN mode) – you can receive information from the Kaspersky knowledge base, while Kaspersky Embedded Systems Security automatically sends statistical information to KSN obtained during its operation. The application can also send to Kaspersky for additional scanning certain files (or parts of files) that intruders can use to harm the device or data.
KSN without statistics sharing – you can receive information from the Kaspersky knowledge base, while Kaspersky Embedded Systems Security does not send anonymous statistics and data about the types and sources of threats.

You can start or stop using Kaspersky Security Network at any time. You can also select another Kaspersky Security Network usage option.

No personal data is collected, processed, or stored. Detailed information about the storage, and destruction, and/or submission to Kaspersky of statistical information generated during participation in KSN is available in the Kaspersky Security Network Statement and on Kaspersky's website.

You can read the text of the Kaspersky Security Network Statement in the Kaspersky Security Network Statement window, which can be opened by clicking the Kaspersky Security Network Statement link.

Anti-Cryptor

Anti-Cryptor allows you to protect your files in local directories with network access by SMB/NFS protocols from remote malicious encryption.

While the Anti-Cryptor component is running, Kaspersky Embedded Systems Security scans remote devices calls to access the files located in the shared network directories of the protected device. If the application considers a remote device actions on network file resources to be malicious encrypting, this device is added to a list of untrusted devices and loses access to the shared network directories. The application does not consider activity to be malicious encryption if it is detected in the directories excluded from the protection scope of the Anti-Cryptor component.

For the Anti-Cryptor component to operate correctly, at least one of the services (Samba or NFS) must be installed in the operating system. For the NFS service, the rpcbind package must be installed.

Anti-Cryptor operates correctly with the SMB1, SMB2, SMB3, NFS3, TCP/UDP, and IP/IPv6 protocols. Working with NFS2 and NFS4 protocols is not supported. It is recommended to configure your server settings so that the NFS2 and NFS4 protocols cannot be used to mount resources.

Anti-Cryptor does not block access to network file resources until the device activity is identified as malicious. So, at least one file will be encrypted before the application detects malicious activity.

Anti-Cryptor settings

Setting	Description
Anti-Cryptor protection enabled / disabled	This toggle button enables or disables protection of files in the local directories with network access by SMB/NFS protocols from remote malicious encryption. The toggle button is switched off by default.
Protection scopes	Clicking the Configure protection scope link opens the Protection scopes window.
Untrusted hosts blocking enabled / disabled	This toggle button enables or disables untrusted hosts blocking. The check toggle button is switched on by default.
Block untrusted host for (min)	In this field you can specify the untrusted host blocking duration in minutes. After the specified time, Kaspersky Embedded Systems Security removes the untrusted devices from the list of blocked devices. The access of the host to network file resources is restored automatically, after it is deleted from the list of untrusted hosts. If a compromised host is blocked and you change this setting value, the blocking time for this host will not change. The blocking time is not a dynamic value, and it is calculated at the moment of blocking. Available values: integer from 1 to 4294967295. Default value: 30.
Exclusions	Clicking the Configure exclusions link opens the Exclusion scopes window.
Exclusions by mask	Clicking the Configure exclusions by mask link opens the Exclusions by mask window.
