How can a user prevent specific applications from accessing a Windows computer over a network?
- Enable MAC address filtering.
- Disable automatic IP address assignment.
- Block specific TCP or UDP ports in Windows Firewall.
- Change default usernames and passwords.
Network applications have specific TCP or UDP ports that can be left open or blocked in Windows Firewall. Disabling automatic IP address assignment may result in the computer not being able to connect to the network at all. Enabling MAC address filtering is not possible in Windows and would only block specific network hosts, not applications. Changing default usernames and passwords will secure the computer from unauthorized users, not from applications.
