Security auditing: Figuring out what versions of operating systems and applications are running on network hosts lets network managers determine their vulnerability to specific flaws. Service discovery: Nmap can not only identify hosts on the network, but whether they're acting as mail, web or name servers, and the particular applications and versions of the related software they're running. OS detection: Nmap can detect the operating systems running on network devices (also called OS fingerprinting), providing the vendor name, the underlying operating system, the version of the software and even an estimate of devices' uptime. Network mapping: Nmap can identify the devices on a network (also called host discovery), including servers, routers and switches, and how they're physically connected. While the basis of Nmap's functionality is port scanning, it allows for a variety of related capabilities including. What makes Nmap stand out as the tool IT and network managers need to know is its flexibility and power. 'It makes Nmap faster and more powerful on Windows and is now used by many other applications as well. 'Right now we are very focused on our and library for Windows,' noted Nmap author Gordon Lyon in an email response to queries about the software. Along with its many other features, Nmap fundamental port scanning and packet-capture capabilities are constantly being enhanced. For example, the low resource overhead of UDP is suited for real-time streaming video, where you sacrifice some lost packets in return for speed, while non-real time streaming videos in YouTube are buffered and use the slower, albeit more reliable TCP. The various protocols serve different purposes and system ports. Nmap employs transport layer protocols including (Transmission Control Protocol), (User Datagram Protocol), and SCTP (Stream Control Transmission Protocol), as well as supporting protocols like ICMP (Internet Control Message Protocol), used to send error messages.
