Fast scan (nmap -F [target]) – Performing a basic port scan for fast result. Host discovery – Identifying hosts on a network. For example, listing the hosts that respond to TCP and/or ICMP requests or have a particular port open. Port scanning – Enumerating the open ports on target hosts.
Network management is the process of administering and managing computer networks. Services provided by this discipline include fault analysis, performance management, provisioning of networks and maintaining quality of service .
The main purpose of Lansweeper derives from a discovery phase of sweeping round a local area network (LAN) and maintaining an inventory of the hardware assets and software deployed on those assets. [3] Reports from the inventory enable complete hardware and software reports on the devices and can be used to identify problems. [4]
Problems may present itself in the form of network faults, performance bottlenecks, compliance issues etc. Some advanced network management software may rectify network problems automatically. Network management software may also help with tasks involved in provisioning new networks, such as installing and configuring new network nodes etc.
Simple Network Management Protocol (SNMP) is an Internet Standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior.
ZMap also speeds up the scanning process by sending a probe to every IP address only once by default, whereas Nmap resends a probe when it detects a connection delay or fails to get a reply. [8] This results in about 2% of IP addresses being missed during a typical scan, but when processing billions of IP address, or potential IoT devices being ...
