7 BEST Advanced Online Port Scanners In 2020

List of the top Advanced Online Port Scanners for Windows and Mac Systems with Detailed Feature Comparison:

Port Scanner is an application that is used to determine the open ports on the network. Port scanning is performed to get information about open ports that are ready to receive information.

Port Scanners are used by programmers, system & network administrators, developers, or by general users. It is used for scanning of own network for finding vulnerabilities before the hackers can find it.

Fact Check: Port scanning is performed by network administrators for network security and network mapping. Hackers also use this Port Scanning process to find the open ports so that they can take advantage of it. Use of port scanners by hackers with malicious intent cannot be directly called as illegal until a hacker performs some illegal act.

Port Scanners are used for testing network security. It can detect the presence of security devices like firewalls etc. Port Scanning can be performed using several methods. Generally, the port scanning process makes use of TCP and UDP protocols.

Five basic Port Scanning techniques are described in the image below.

Port Scanning Process

Port Scanning is a five-step process as described below.

  • Step1: For port scanning, there is a need for active hosts. Active hosts can be discovered using the network scanning process.
  • Step2: These active hosts are mapped to their IP addresses.
  • Step3: Now we have active hosts and thus port scanning process is performed. In this process, packets are sent to specific ports on a host.
  • Step4: Here responses will get analyzed.
  • Step5: Through this analysis, information about running services will be learned and potential vulnerabilities will be identified.

Port Scanners can connect to a wide range of ports or IP addresses on a network. It can also connect a single IP address or a specific list of ports and IP addresses. Different levels of port scanning include Basic Port Scan, TCP Connect, Strobe Scan, Stealth Scan, etc. It can perform many other different types of scan.

There are two categories of port scan techniques i.e.Single source port scan and distributed port scan.

The categories of Port Scan Techniques are illustrated in the below image.

Pro Tip: While performing port scanning, or before you use a port scanner, decide the range of network that you want to scan (Single IP address or a set of ports and IP addresses). After that, the port scanner should be configured to the depth as per your requirement.
