Problem
You need to install KEA on a host running MS Exhange 2013, 2016, 2019 server, and ensure compatibilty.
Solution
Add the following values into registry (should be done with "Local System" rights):
[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\KasperskyLab\SOYUZ\4.0\Environment]
"EnablePorts"=dword:0000
If you are writing your own rules for YARA engine on Central Node, you may need available modules in YARA and engine version.
Engine version is 3.7-3.11 in KATA 3.7.x
Engine version is 4.10 in KATA 4.1 and KATA 5.0
Here's the list of modules:
tests
pe
elf
math

How to upgrade previously installed password protected KEA using KSC remote installation task.
Step-by-step guide
Edit attached file install_props.json, put there your password for already installed KEA;
Put this file to folder on KSC containing files for creation of remote installation package for new KEA version as per screenshots below;
Create on KSC package for remote installation;
Start remote installation task on KSC.
Most of the time KEA core patches are cumulative and it is sufficient to install the newer one on top of the previous in order to fix new issues.
However, sometimes, for troubleshooting purposes or otherwise, you would need to remove an existing patch. This is how it's done.
Step-by-step guide
In the Administration Console, go to Advanced → Remote installation → Installation packages;
In the right frame, click Create installation package;
Select Create installatio
Problem
Some users may face a rather unclear and not self-explanatory error when attempting to remotely install KEA for Linux:
Remote installation has been completed with an error on this device: Installation error Error in PREIN scriptlet in rpm package epagent
Error: Transaction failed
Solution
As the first step of troubleshooting of KEA, we recommend installing the latest core patch.
However, sometimes such installation will fail. There are two popular causes of this:
EULA is not accepted;
KEA installation is protected with a password.
This guide addresses both of these issues.

Sometimes one may need to enable transmitted traffic capturing in KATA (in example, for local testing of Suricata detections).
Here's how to do it.
Instructions for KATA 3.7.*
In file /etc/modprobe.d/pf_ring.conf set enable_tx_capture=1. File should look like this:

This article applies to Endpoint Agent for Linux. To collect LENA debug or ANY traces, please follow this guide.
Default traces location is '/var/log/kaspersky/epagent/'.
Default dumps location is '/tmp/agentdumps'
Public collect.sh script was updated to collect LENA-related information and gather these folder as well.
How to: enable LENA ANY traces
For KATA-EDR (on-premises) customers to tune LENA performance by exclusions, ANY level logs are required. To enable ANY log
Problem
You may encounter issues with KEA that may include:
Excessive resource consumption
Freezes, crashes
etc.
Solution
Install the latest available core patch.
Adding KEA CF to KEA installation package is not supported and will not work, patches need to be installed separately.
To install patch using KSC or locally use the following keys, /qn can be added for silent install as usual
How to install patch
Kaspersky Endpoint Agent, as many other products, has a few different ways of enabling traces.
Traces folder
NB! The folder specified for traces must exist and be writable. KEA will neither create folder nor display any error if it doesn't exist.
One may choose which is best suitable for their needs:
Traces with restart
In 99% cases, information that is written only during initialization, that is, after KEA restart, is critical for inves
KATA / EDR is using only one certificate for all connections (like WebServer and Client Connections). When you plan to replace it, do it in an early stage of deployment.
If you want to replace the TLS certificate, you will need to:
Reauthorize mail sensors (KSMG, KLMS) on Central Node.
Reconfigure connection of Central Node, PCN and SCN to Sandbox.
Reconfigure Endpoint Agent traffic redirection to Sensor and trusted connection with Endpoint Agent.
Upload a new c

Problem
If you install standalone Kaspersky Endpoint Agent, both KSC installation package and local installer provide option to choose, which KEA components to install:
However, when KEA is installed in built-in scenario, bundled with KES or KSWS, you don't get to choose and KEA is installed in default configuration, with all the components.
There's a way to select installed KEA components even for built-in scenarios.

You may need to add a batch of prevention rules to KATA. To speed up the process, we have created a script sample.
Adding more than 1000 prevention rules will require additional PF to improve Web UI performance. Please contact technical support to get this PF.
Adding more than 5000 prevention rules is highly NOT recommended as it may result in drastic performance degradation on both CN and Endpoint Agent.

Sometimes, you may need to check KSN servers availability and operation on KATA CN.
This method is not applicable to KATA 6.0. The tool is still present, but it returns error 0x80000001 (Interface not supported).
For KSN issues, there's a way to check specific hash for reputation:
