Network scanning and port/application detection using Nessus, OpenVAS, and Nmap.
Network scanning is the process of assessing a network to identify active host network, either an attacker or a medium for security assessment. This procedure plays an extremely vital role in risk assessment programs or while preparing a security plan for your organization.
This course starts with the concept of network scanning and how an organization can benefit from it. Then we delve into different scanning techniques such as port and firewall detection, TCP/IP port detection, OS detection, and so on. We also implement these concepts using a few of the most prominent tools on the market such as Nmap, Nessus, and OpenVAS.
By the end of this course, you will have hands-on experience in performing network scanning using different tools and choosing the best tool for your system.
