Network port scanner has become an essential part of IT admins go-to tools to secure networks with port scanning and network port investigation. Ports act as communication terminals that allow message passing between different network components by running various services. An effective port scanner tool enables full fledged network port scanning to determine which ports on your network are open and what services are running on them. Since ports act as a bridge between your server/desktop and the network, open ports that are left unmonitored might act as a passageway allowing malicious access into your systems. In order to avert these intrusions, scanning the entire network using a port scanner, has become a day-to-day network activity for many network admins.
OpUtils’ port scanner is a code-free, intuitive network port scanner that allows you to quickly find open ports in your network, the services running on them, and their response time by pulling real time port scan status. Generate a list of closed, open, or listening ports by conducting end-to-end port scan on a range of available IP addresses and their TCP and UDP ports with port scanner. OpUtils' port scanning software provides insights into each system’s footprint by enabling you to access and view all the services that are running on the system’s network endpoints/ports.
To avoid the risk vector of malicious agents exploiting your network, by using the code found in the server software, network port scanner offers various port scan features. These port scan capabilities enable you in testing all ports, which is vital to achieving an in-depth security verification.
On a large network, monitoring and managing open ports can be extremely time-consuming. Ports enable services to communicate with the applications running on your devices by exchanging data. When a port is left open, it can be easily infiltrated by malicious agents, causing unusual network traffic that indicates an infected system.
OpUtils' port scanner tool conducts continual and periodic port scanning routines and displays the details of the scanned ports, including their status. Using this list pulled by the network port scanner, you can identify and close all open ports and block ports exhibiting malicious traffic, thereby securing your network resources from unauthorized access.
OpUtils port scanner software provides you the option of directly scanning your network ports with the port scanner tool available under network tools, or you can continuously monitor your network ports using the product’s Switch Port Mapping feature.
You can easily scan specific ports in your network using the Port Scanner tool by following these three simple steps:
Step 1: In OpUtils, under Toolset, open the Port Scanner Tool that is available below the Network Monitoring tools.
Step 2: The 'Start-End IP Address' option is selected by default for scanning a range of IP addresses. If you wish to scan a specific IP address, select the 'Single IP Address' option.
Step 3: Specify the starting IP address and the ending IP address of the managed IP address block along with the port range and press scan. If you have chosen to scan a single IP address, specify the specific address and port range to scan.
The Port scanner tool scans the specified network ports and displays the ports, their response time, their status, and the services running on them.
OpUtils’ port scan software - Switch Port Mapper automatically maps your switches and ports when you add your switches and displays their status. Learn more about managing ports using switches.
Switch port scanner provides you visibility into the ports connected to a particular switch, and the devices connecting to the ports. It also tells you if there is a hub connection using the network port scanner.
OpUtils' IP port scanner probes the target ports in your network by sending an IP packet to each port. Based on the response from the ports, OpUtils' network port scanner marks ports as open and listening or closed. This provides visibility into the available ports in your network, the services running on them, and the list of open ports. The advanced port scanner can also fetch information that can be used to identify the presence of security devices such as firewalls between the source and the target—a technique known as network fingerprinting.
Network ports are usually numbered from 0 to 65535, with different ports running different services, each having a service name. These services run over the port scanner network transport protocols such as TCP, UDP, DCCP, and SCTP and can be traced by effective network port scanners. Ports numbered from 0 to 1023 (system ports) are known as “well-known ports” or “standard ports” and have been assigned the commonly used internet services. OpUtils’ network port scanner software allows you to scan these well-known ports along with the other network ports by specifying the port range to be scanned.
Some of the common port services scanned by OpUtils’ port scanning software are:
