How are credentials stored in EventLog Analyzer

Hello,

I was wondering if I could get a little bit of technical information regarding Eventlog Analyzer and how it handles authentication and encryption. I am particularly interested how credentials are stored for Windows hosts. Since these users have admin privilege, it's very important to me that the credentials are safe in case the Eventlog server becomes compromised and the database is exposed. I am also interested in how the Eventlog server talks to different hosts. Are these channels encrypted? I think WMI queries are, or can be at least, but I am not sure. For syslog, can it be secured by TLS like syslog-ng does? Any information about these topics would be greatly appreciated.

Thanks very much,
Paul
