Logging creates a summary of the process. Usually stored in .txt.

The file structure, I hope, is familiar to us… The very essence of the file displays the endpoints where the server is knocking. In the case, as in our case, with a VPN connection – we see ports (IPv4/IPv6) and traffic tunneling cases.
Logs are often used in testing and secure development. You can see attempts to communicate/hit the system via DDoS. They do not display internal parameters, only the fact of the event, date/time, port and protocol.
<acguiNotice module="com.cisco.anyconnect.presentation.vpn" type="update" timestamp="16.11.2021 20:58:17" state="Neutral"> – example of normal connection.
<acguiNotice module="com.cisco.anyconnect.presentation.vpn" type="update" timestamp="18.11.2021 16:49:37" state="Error"> – example of a faulty connection.
When developing, it is useful to log the product and the development stage not only for reporting to the business customer, but also for yourself in the future. At work, I used Confluence/Jira to summarize tasks and developments.
