Problem kesl-control --app-info outputs the following error: en File Threat Protection: Unavailable due to file interceptor driver error One of the most common root causes is Fanotify is disabled (or KESL could not access it) and kernel module compilation also failed. A special utility can be used for this directly on the affected machine with KESL installed: sudo /opt/kaspersky/kesl/bin/fanotify-checker && echo fanotify: supported || echo fanotify: unsupported In case, an operating system does not support Fanotify technology, it is required to install some additional packages and build a kernel module for KESL. A part of required packages may be found on the Hardware and software requirements section of the product documentation, for example for KESL 11.3; In addition to this, new packages kernel-headers-XXX and kernel-devel-XXX must be installed, where XXX - an operating system kernel version. Use the following scenario to install those packages and build a kernel module for KESL: for RHEL based OS: yum install kernel-headers-`uname -r` kernel-devel-`uname -r` for Debian based OS: apt install linux-headers-`uname -r` Reboot the system; Run the post-install script: /opt/kaspersky/kesl/bin/kesl-setup.pl --build | tee /tmp/buildLog And reboot the service: systemctl restart kesl-supervisor.service In case of any further issues, please contact Kaspersky Support.

Updates metadata is downloaded by Download Updates to the repository task. Updates themselves are downloaded by Install updates and fix Vulnerability task. What is a source folder containing the third party application updates on the administration server? 3rd party updates are downloaded into the folder C:\ProgramData\KasperskyLab\adminkit\1093\.working\wusfiles, then copied to C:\ProgramData\KasperskyLab\adminkit\1093\.working\FTServer to transfer to the hosts. If I run Install updates and fix Vulnerability for Google Chrome as example, all versions of Chrome will be upgraded to the latest release? Which means after a while of running task I will get one version of Google Chrome on all PCs? It depends on settings specified in the install task. For example, if you choose to install all applicable updates, Google Chrome will be updated on all hosts to the latest version. If I have a Connection Gateway, the devices outside the network and connected to the KSC through Connection Gateway will update through KSC or Connection Gateway? Firstly, updates will be transferred to Connection Gateway, then distributed from Connection Gateway to the hosts. So if host needs update which is already on the Connection Gateway, KSC will not distribute files again. CG will distribute them to the hosts. Is it possible for the PCs outside the network and connected through Connection Gateway to use the internet as an update source for third party application? Indeed. 1. On the host with the KSC server, create the following registry key: [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\KasperskyLab\Components\34\1093\1.0.0.0\ServerFlags] "KLSRV_SYSPATCH_DOWNLOAD_PATCHES_LOCALLY"=dword:00000001 2. Recreate the Install updates and fix vulnerabilities task.

Advice and Solutions (Forum Knowledgebase) Disclaimer. Read before using materials. KSC13 introduced a feature that limits the frequent publication of events. In the event that the event storage overflows on the Server, the most common event in the storage is calculated, and such events are blocked when published on hosts. Problem: Machines have status "Virus scan wasn't performed for a long time" but the "Virus scan" task was started recently. Events that occur on local hosts (KES) are not displayed on the administration server (KSC). Cause: KSC 13 has a new functionality to limit the storage of frequent events. When the set event storage limit on the Administration Server is reached, the most frequently occurring event (in the database) is calculated and added to the block-list. After that, the events that occur and are displayed on the KES hosts, when received by the server, will be blocked and will not appear in the storage. This gives rise to a problem with updating host statuses on server - since the event was not written to the database, then server-side processing does not occur and the host in the Managed group does not receive the status update. Solution: Since this problem is directly related to the storage and publication of events, it is first of all necessary to find out what causes the event store to overflow: Find out which events appeared in the block list of the Administration Server ("Managing frequent events blocking" article). After finding out the cause of the overflow, the following can be done to fix the problem: Increase the number of events stored on the server database ("Setting the maximum number of events in the event repository") Set up event logging by deleting irrelevant ones and thereby reducing the flow of events stored on the server. Clear the block list for events on the administration server ("Removing blocking of frequent events")

How to add second license to the workspace There is no possible way to add second license to KES Cloud. License will be replaced. Kindly merge the license count to one and add it. Email notification about outdated databases There is no separate email notification settings for "database outdated" event. License receiving after installation After installation of KES, device can receive a license even without an owner. License applying can take some time due to the attempt of synchronization with KES Cloud server. Standard sync period is 15 mins. KES Cloud email notifications in cumulative emails When you have a lot of notifications, they will be sent as cumulative email. This is by design and expected behavior. These emails contains information about count of emails with different levels of severity. KES Cloud workspace deletion after license expiration If license expires, workspace without active license will be deleted. If commercial license was used - after 90 days. If trial license was used - after 30 days. Reports' time zone differences Time of report creation depends on browser localization. Events in report opened in Cloud console also depend on browser localization. Events in report exported in .pdf - UTC +0.

These errors appear when the remote installation task of NAgent or KES with NAgent was created with the Assign package installation in Active Directory group policies option selected. At the first startup they start under the account specified in the New Task Wizard. If that user has access for creating domain policies and groups, the task will be completed successfully, and "GPO" and "Security Group" with target computers will be created on domain controller. When deleting this task, the user credentials entered in the task settings are used. If they are changed, or if the task is being deleted by another user who does not have sufficient rights in the domain, or if the user who created the task has lost its rights, the errors will occur: Error in EventLog Failed to delete group policy object 'LDAP://CN={1DEE8F3C-F36F-4FF7-8E18-01C83D482A44},CN=Policies,CN=System,DC=bn,DC=loc': 'System error 0x52E (The user name or password is incorrect.)'

It is impossible to detect .bat and .cmd files by format, because these are regular plain text files. If you want to block attachments, you can only configure detection of these files by masks: *.bat, *.cmd. Please check the section "Configuring the general settings and conditions of rules" of the sites https://support.kaspersky.com/KS4Exchange/9.6/en-US/166855.htm Add a condition for the Attachment filtering rule and select File name mask instead of File format and then add *.bat or *.cmd to the list.

Administrator receives the notification about outdated anti-spam (AS) and/or anti-virus (AV) bases because a large time interval for updating AS and/or AV databases is set (every 5 hours or more for AS and every 24 hours or more for AV). Anti-spam and anti-virus bases should be updated much more often. Accordingly, Kaspersky Security Center should also update anti-spam and anti-virus bases more frequently. The best way is to update anti-spam bases directly via Internet from Kaspersky Update servers every 5 minutes. Anti-virus bases should be updated every 1 hour. If it is not possible, try to update Kaspersky Security Center and Kaspersky Security for Microsoft Exchange anti-spam bases every 30 minutes or every 1 hour, but in this case you should not expect a high spam detection rate.

они несколько раз ее решали, я не первый год на этом форуме и помню эти истории. Только потом проблема опять выплывала через какое-то время. В конце концов его добавили в список несовместимых. Просто это было пассивное добавление, которое ни к чему не обязывало. Ну а в последней версии об этом стали явно предупреждать. Вопрос в том, это только предупреждение при установке, которое можно обойти или продукт будет теперь периодически об этом напоминать?

Problem: When deploy the SVM of KSV LA on the vSphere 6.5, the following error may occur: Reason： This issue occurs because vCenter Server cannot detect any vSAN storage provider. There is no way to detect vSAN storage provider if no hosts are available when vCenter Server starts. Note: vSAN storage provider cannot be recognized automatically even after host start working properly. Workaround: This is a known issue affecting vCenter Server. To workaround this issue, you have the following options: 1. Initiate synchronizing vSAN storage provider by clicking icon for synchronization in the page: vCenter Server -> Configure -> Storage Providers 2. Make sure at least one host is working when starting vCenter Server.

KSO365 is a cloud solution. It does not work in the cloud by itself but together with Microsoft Exchange Online (EOL) and its anti-spam and anti-virus protection. In more than 95% of cases, Microsoft Forefront (Ff) performs the spam and virus scans first, due to Microsoft's cloud architecture. Thus, if Ff has identified an email as spam, virus, phishing, etc., and has done with it any action (according to the settings) except “Skip”, we do not check this email and do nothing with it. We cannot change the verdicts given by other applications. If an email went to the user's box without Ff detects or with the “Skip” action, KSO365 comes into play. It performs all the scans that the user has enabled, gives its verdicts and performs the actions configured by the user. Special mention should be made of the SCL parameter, which is necessary when working with spam detection. This is the only general letter parameter that KSO365 can change but only upwards.

Description When installing or upgrading KSE, you may encounter various issues when installing or starting our service. If a user has repeated the installation many times and changed many settings manually, we recommend to remove KSE completely using the instructions below. Cause There are files that remain in the system from a previous KSE installation, so a new installation cannot be successful. Solution Delete the remaining KSE files from the Exchange server manually. Follow the instructions below. 1. Delete all the remaining KSE agents. To do so, start Exchange Management Shell and run the following command: Get-TransportAgent -TransportService FrontEnd If the KSE agent is on the list, run the command: Uninstall-TransportAgent -TransportService FrontEnd -Identity "Kaspersky Security antispam Frontend Cas agent" 2. Run the following command: Get-TransportAgent See what KSE agents are on the list. Run the command below for every KSE agent. For example: Uninstall-TransportAgent “Kaspersky Security routing antispam filter agent” Uninstall-TransportAgent “Kaspersky Security antispam filter agent” Uninstall-TransportAgent “Kaspersky Security antivirus filter agent” Insert the names of KSE agents from your list. 3. Restart the Transport Agent service using the command: Restart-Service "MSExchangeTransport" 4. To make sure that there are no more KSE agents, run the following commands again: Get-TransportAgent -TransportService FrontEnd and Get-TransportAgent 5. Set Disabled for Kaspersky Security For Microsoft Exchange Servers service startup and stop our service. 6. Import the removeregkeys.zip archive to the registry. 7. Restart the MSExchangeIS service: restart-Service MSExchangeIS 8. Remove the folder where KSE was installed. If possible, restart the server.

Advice and Solutions (Forum Knowledgebase) Disclaimer. Read before using materials. When troubleshooting typical KSC issues, you will likely need to check the availability of TCP port 13000 on the KSC Server. Both telnet and akconnect tools can be used to achieve this. Syntax is very simple: akconnect host port Examples: akconnect.exe 192.168.1.19 13000 >akconnectoutput.txt telnet 192.168.1.19 13000 >telnetoutput.txt Where 192.168.1.19 is the IP address or DNS name of the KSC Server and 13000 is the port number. Results will be logged to .txt files that should be sent to Kaspersky support for verification. Please be advised that telnet is not installed by default in the recent versions of Windows. You can add it using the appwiz.cpl→Add feature. You can download the akconnect utility here.

Based on a network location. Which one will have a higher priority for the PC? Among the update agents assigned to administration groups, the one assigned to the administration group, that is closest to the target host in the group hierarchy, has the higher priority. If the update agents are assigned to the same group, they have an equal priority. The priority of update agents assigned based on the network location is equal to the priority of the nearest update agent in the group hierarchy. If two update agents have the same priority, the one, the route to which is closer in the number of passed routers, is selected. If two update agents have the same priority and the network distance to them is the same, the agent is selected randomly.

Advice and Solutions (Forum Knowledgebase) Disclaimer. Read before using materials. Dynamic hosts require more KSC resources than regular hosts. When a new host is connected to KSC (and the dynamic host is considered new), an icon and a new entry in the database are created, full synchronization with the agent is performed, and the host moved to a group. When the host is deleted, all information about it is deleted as well. These operations consume a lot of KSC resources, while static hosts require them to be performed only once. Recommended sizing (no more than 20 000 VDI hosts) may not be fully and correctly loaded. In industrial use, for each icon the following network lists are created: - hardware - installed software - detected vulnerabilities - events and lists of executable files of the Application control component. Size of these lists directly affects KSC performance as well as SQL server performance when performing internal procedures, and the load may grow in the non-linear way. If the use of the solution with your policy settings, environment and virtual desktop properties shows moderate consumption of resources during standard operations, then the number of managed VDI hosts can be increased up to the limit of resources available in the current configuration. Consumption of 80% of memory and 75-80% of available cores is considered moderate.
