McAfee Firewall (Sidewinder) Logs - session end and session drop differences

[kimchicupper]

Hi All,

Anyone can assist in explaining the difference in the event: session end and event: session drop?

Does it means that for event: session end, the connection was successful, completed and ended, thus a session end log?

Where else for event: session drop, the connection was denied/blocked thus drop?

Appreciate your assistance in this. Thank you.
