Practical Network Scanning

By: Ajay Singh Chauhan

Overview of this book

Network scanning is the process of assessing a network to identify an active host network; same methods can be used by an attacker or network administrator for security assessment. 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. We also implement these concepts using a few of the most prominent tools on the market, such as Nessus and Nmap. 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.

Physical security 


In most cases, physical access translates to a total loss of security. Even if they can't access your data, an attacker can do a lot of damage. We'll take a look at the most essential security measures everyone should implement, if they haven't already been done:

  • Lock up the server room: The server room is the power station of your physical network, and someone with physical access to the servers, switches, routers, cables, and other devices in that room can do enormous damage.
  • Set up surveillance: You need a way to monitor who goes in and out, what they do and when they do it. A better solution is to set up biometric scanners that are required in order to unlock the doors, and the identity of each technician is then recorded. Surveillance cameras can monitor continuously, or they can use motion detection technology to record a person's movement. They can even send an email or cell phone notification if motion is detected when it shouldn't be.
  • Disable the drives: Of course...
