These features are extensible by scripts that provide more advanced service detection, [7] vulnerability detection, [7] and other features. Nmap can adapt to network conditions including latency and congestion during a scan. Nmap started as a Linux utility [8] and was ported to other systems including Windows, macOS, and BSD. [9]

Proxy scan - a proxy (SOCKS or HTTP) is used to perform the scan. The target will see the proxy's IP address as the source. This can also be done using some FTP servers. Idle scan - Another method of scanning without revealing one's IP address, taking advantage of the predictable IP ID flaw. CatSCAN - Checks ports for erroneous packets.
Once a successful scan is completed there is no trace of the attacker's IP address on the target's firewall or Intrusion-detection system log. Another useful possibility is the chance of by-passing a firewall because you are scanning the target from the zombie's computer, [ 10 ] which might have more rights than the attacker's.
The Advanced Intrusion Detection Environment (AIDE) was initially developed as a free replacement for Tripwire licensed under the terms of the GNU General Public License (GPL). The primary developers are named as Rami Lehti and Pablo Virolainen, who are both associated with the Tampere University of Technology , along with Richard van den Berg ...
In computing, a ping sweep is a method that can establish a range of IP addresses which map to live hosts.. The classic tool used for ping sweeps is fping, [1] [2] [3] which traditionally was accompanied by gping to generate the list of hosts for large subnets, [4] although more recent versions of fping include that functionality.

ShieldsUP is an online port scanning service created by Steve Gibson of Gibson Research Corporation.The purpose of the utility is to alert the users of any ports that have been opened through their firewalls or through their NAT routers, which can be used by malicious users to take advantage of security vulnerabilities.
Multiscanning is running multiple anti-malware or antivirus engines concurrently. Traditionally, only a single engine can actively scan a system at a given time. Using multiple engines simultaneously can result in conflicts that lead to system freezes and application failures.
