Contents and storage of trace files

You are personally responsible for the security of the data that is stored on your computer, particularly for monitoring and restricting access to the data until it is submitted to Kaspersky.

Trace files are stored on the computer as long as the application is in use, and are deleted permanently when the application is removed.

Trace files, except trace files of Authentication Agent, are stored in the folder %ProgramData%\Kaspersky Lab\KES.21.19\Traces.

Trace files are named as follows: KES<21.19_dateXX.XX_timeXX.XX_pidXXX.><trace file type>.log.

You can view data saved in trace files.

All trace files contain the following common data:

• Event time
• Number of the thread of execution

  The Authentication Agent trace file does not contain this information.

• Application component that caused the event
• Degree of event severity (informational event, warning, critical event, error)
• A description of the event involving command execution by a component of the application and the result of execution of this command.

Kaspersky Endpoint Security saves user passwords to a trace file only in encrypted form.
