Choosing Port Scanning Software Essay
Openness: Open Source systems are usually designed with integration in mind; whereas commercial systems have business motivations to lock organizations into a closed system. Fast bug and security fixes: Open source software usually has many people combing its source code, who rapidly fix problems as they are discovered. (3) 4. 1 would recommend him using Map. Map is the most popular port scanner. Map (“Network Mapped”) is an open source utility for network exploration or security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts.
Map Uses raw IP packets in novel ways to determine what hosts are available on the network, what services (ports) they are offering, what operating system (and SO version) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. Map runs on most types of computers, and both console and graphical versions are available. Map is free software; available with full source code under the terms of the GNU GAP_. 3 Map is an excellent security tool because it allows you to determine which services are being offered by a system.
Because Map is optimized to scan large IP ranges, it can be run against all IP addresses used by an organization, or all cable modem IP addresses provided by an organization. After using Map to find machines and identify their services, you can run the Nesses vulnerability scanner against the vulnerable machines. Map supports an impressive array of scan types that permit everything from TCP SYNC (half open) to Null scan sweeps.
