1. Identifying the Logon account and the source workstation when blank or unknown
Tools likeWiresharkcan be used to keep an eye on your network on a microscopic level. It can capture the traffic simultaneously when someone tries to log in and helps you find the source. The tool can identify IP addresses so that you can easily locate the logons.
2. Identifying the Logon account and the source workstation if there is a remote client
You can use your firewall to protect your server or computer from unknown login attempts. Follow the whitelists approach (block all, allow some) instead of denylists (allow all, block some). This will ensure that only authorized attempts are initiated outside the network.
Using a reliable VPNcan also help you safe-keep your network. It will let remote users connect to the local server and then authenticate normally.
A great VPN option that we recommend is Private Internet Access (PIA) because it is fast and highly customizable and has unbreakable security thanks to its numerous privacy features that will keep your activity always safe.
