Final answer:
To monitor remote connections on the client side in Windows, check the Security Log in Event Viewer for event IDs 4648 and 4624, and also check the TerminalServices logs for detailed remote connection information.
Step-by-step explanation:
A good Windows event to monitor for detecting remote connections on the client side is the Security Log within the Windows Event Viewer. Specifically, you should look for event ID 4648, which signifies a successful logon with explicit credentials, commonly seen with remote connections. Additionally, event ID 4624, which indicates a successful logon event, can also be monitored to determine when a user has logged on to the system, which could imply a remote connection if the logon type is 10 (RemoteInteractive/RemoteDesktop).
For more detailed monitoring, the TerminalServices-LocalSessionManager and TerminalServices-RemoteConnectionManager logs can provide a wealth of information about remote desktop connections, including start and end times of sessions. Using these logs effectively helps in tracking both incoming and outgoing remote connection attempts, ensuring better security and oversight over remote access within a network.
