You can always use netstat command to get list of connections under Windows. Open command prompt by visiting Start > Run > Type "cmd" in box.
netstat is a command line utility which displays protocol statistics and current TCP/IP network connections in a system. Type the following command to see all connections:
netstat -noa
Where,
- n: Displays active TCP connections, however, addresses and port numbers are expressed numerically and no attempt is made to determine names.
- o: Displays active TCP connections and includes the process ID (PID) for each connection. You can find the application based on the PID on the Processes tab in Windows Task Manager.
- a: Displays all active TCP connections and the TCP and UDP ports on which the computer is listening.
netstat -ano | find /c "80"
Find the IP address which is having maximum number of connection and block it using Cisco firewall or IPSec. Another protective measurement is to harden the TCP/IP stack.
