This procedure plays a vital role in risk assessment programs or while preparing a security plan for your organization.
Practical Network Scanning starts with the concept of network scanning and how organizations can benefit from it. Then, going forward, we delve into the different scanning steps, such as service detection, firewall detection, TCP/IP port detection, and OS detection.

In the concluding chapters, we prepare a complete vulnerability assessment plan for your organization.
By the end of this book, you will have hands-on experience in performing network scanning using different tools and in choosing the best tools for your system.
