Network scanning is a critical step in ascertaining the security of a network. Some types of scans include the following:
Network Sweeping – This type of scan sends a series of probe packets to identify live hosts at the IP addresses in the target network.
Network Tracing – This type of scam is closely related to network sweeping. During this scan, we attempt to determine the network topology so that we can draw a network map.
Port Scanning – This type of scanning is used to determine the TCP and UDP ports that are listening on the target system.
