Scanning are three types:-
1. Port Scanning
2. Network Scanning
3. Vulnerability Scanning

So Today we only discussed on the Port Scanning.

Port Scanning:-

Port Scanning is one of the most popular reconnaissance techniques used by hackers to discover services that can be compromised. So in this we identify the open and available TCP/IP Ports on a system. In Port Scanning we identify the open and available TCP/IP Ports on a system. So in simple we can say that in port scanning we discover or find the secuirty holes that we can use against the system or our target.

Port-scanning tools enable a hacker to learn about the services available on a given system. Each service or application on a machine is associated with a well-known port number.

A port scan helps the attacker find which ports are available (i.e., what service might be listing to a port). Essentially, a port scan consists of sending a message to each port, one at a time. The kind of response received indicates whether the port is used and can therefore be probed further for weakness.

Port numbers are 16-bit unsigned numbers.The port numbers are divided into three ranges:

• Well Known Ports (0 – 1023)
• Registered Ports (1024 – 49151)
• Dynamic and/or Private Ports (49152 – 65535)

Ports numbered 0 to 1023 are considered well known (also called standard ports) and are assigned to services by the IANA (Internet Assigned Numbers Authority).

Non-Standard Ports

By a non-standard port, we simply mean a port whose number is higher than 1023. In this range also, several services are “standard.”

Scanning as its name implies it is technique which is used to gather information for our targeted network and it’s host systems.

Scanning is the first phase of ethical hacking where actual hacking will be start.

Scanning is the process of locating targeted systems that are alive or responding on the network. For this hackers used the IP addresses, operating systems, services and installed applications to find the type of exploit which he later used in the hacking process.

Ethical Hacker used the Scanning to find the target system’s IP addresses.

Why Scanning Performs:-

1. To determine the perimeter of the target network/system.
2. To facilitate network mapping.
3. To Build and Inventory of accessible systems on target network.

In our next article we discus on the types of Scanning?
