It scans the network or the concerned network devices in order to ensure if they meet the requirements to adhere to the compliance. Qualys can also be considered as the other best network scanning tool. Based on the kind of protocol we use while scanning the network, it takes the required time and also tries to establish the connection accordingly. It confirms of any port is filtered, closed or open. It is the base of tools like nexpose, which means all the operations performed by nexpose are actually performed using Nmap in the background. There are some default values associated with the attributes, and by using such attributes, we can perform an efficient network scan. Nmap can also detect the operating system of the host or the network device that it scans. While using this utility, several attributes could be used in order to customize the scan.

It is a strong eno to scan all the 65535 ports. It runs the scan in order to check the status of a port by using either TCP or UDP protocol. NMap may be considered another command line-based network scanning utility found inbuilt on some of the Linux distribution. Also, if services are running on the device, it also finds out the service version to check if that version is vulnerable. It is also capable of checking the configuration file to ensure the vulnerabilities. It checks for the services running on the network devices and their version to determine if the version is weak for the attack. Like nexpose, it also examines special files and folders that consist of the data related to the device’s security configuration. Tannable has developed this tool, and in the current period, it has been used by more than twenty-five thousand organizations. Nessus can be considered the other network scanning tool used to ensure the security of the application by magnifying the vulnerabilities. The network scanning could be performed using either the command line utilities of the Linux operating system or some of the cloud-based applications. Another reason that usually leads to vulnerability in the network is using the old versions of any service. The network scan is all about checking for the security misconfigurations in the network devices. It may be defined as the tools used to perform a scan on the network to detect the existing vulnerabilities. In this course, we will learn about the tools used to perform network scanning. For the purpose of finding the vulnerabilities, we will need to scan the network or the networking devices. To keep the network secure from the attacks, we need first to identify the networking devices’ vulnerabilities. The web application can be protected by opting for a secure coding method, while the other network devices can be protected by using the configuration.

If we talk about the system’s security, all these devices are supposed to be secure to provide overall security to the system. The system may consist of several things like a web application, servers, routers, network architecture, and other network devices. A digital system that belongs to any organization is usually comprised of several technologies.
