1.1. Scenario:
KATA/EDR CN is deployed on site, and there are some remote users that cannot connect to the internal network, and you want to receive the EDR telemetry from those endpoints and laptops when they are outside the network (considering that you don't have any VPN functionality).
You don't want to expose the CN on the internet, so you'd like to use the sensor to relay the telemetry to the CN and have visibility on the endpoints.
1.2. Pre-requisites and configuration step
Description and cautions
This article may be useful in certain cases, when you see that virtual machines running on the KATA Sandbox can not access internet using the properly configured malware interface. One can notice the issue based on several symptoms, such as VM activation errors, samples sent to Sandbox for processing not accessing internet, etc... We recommend to use the following article to check if the malware channel works properly on the KATA Sandbox server or not:

Don't apply to PCN, it will lead to the disconnection of all SCNs attached and will not restore automatically
Problem Description
A PCN connection request got stuck in the "Waiting" status and doesn't result in failure. The reboot doesn't help. It can happen if, for example, a SCN IP was specified instead of PCN.
Solution
Run the following commands as root:
As stressed in the product documentation, Sandbox, which is deployed as a Virtual Machine, should have an exact sizing, violation of which may lead to various issues. The only parameter that can be varied is a CPU clock rate.
Common mistake
The most notable mistake regarding scaling up VM sandboxes is an attempt to make one huge Sandbox VM with two to four times the required RAM/CPU as dedicated resources.
Correct approach is to create a respective number of additional VM

Versions
Applicable to versions above 5: 5.0, 5.1, 6.0, 6.0.1, etc.
You can fancy access log-history logs (former apt-history) directly for convenience purposes or if the kata-collect-siem-logs tool is malfunctioning for some reason.
These logs are in gzip, sorted by dates, as files with names in format: /data/volumes/s3proxy/log-history/YYYY-MM-DD-HH-MM-SS, where YYYY-MM-DD-HH-MM-SS is the datetime.
basename -a /data/volumes/s3proxy/log-history/2024*
Versions
Applicable to versions later than 5.0, 5.1, 6.0, 6.0.1, etc.
Problem
There are several cases where the standard method of changing interface network settings via the Web UI is not available, e.g. the Web UI is inaccessible.

Scenario:
KATA/EDR CN is integrated with the KPSN server, and you want to enrich the KPSN reputation database with the detections from the sandbox server. You can integrate a KATA Platform Central node with the KPSN reputation database and automatically populate it with information about the files that the sandbox technology finds to be dangerous and highly important.
Pre-requisites:
To configure sending checksums of the files detected by the sandbox technology to KPSN, you will n

Problem
In previous versions of KATA it was possible to mount an NFS share to copy backups to. In KATA 5.x only CIFS share mounts are available out-of the box.
Error

mount: /mnt/nfs: bad option; for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount.<type> helper program.
Issue
In KATA 4.1, when Central Node was used as Sensor, it was possible to access Traffic Capture and disable protocol, e.g SMTP.

Problem
You may use images with installed KEA that are distributed to multiple devices, or some hardware vendors (ACER) do not comply with standards and sell hardware with non-unique BIOS IDs, etc.
As a result, a telemetry from different agents may end up merged into a single record.
Symptoms
Certain hostnames are present in KATA alerts, but search returns 0 events. Mo
