No matter how secure your network infrastructure is and no matter what services your server runs, there are certain basic hardening techniques you must apply. In this chapter, we focused specifically on hardening steps that apply to any server. In particular, we discussed the physical security of server resources, followed by disk encryption techniques one can use for on-premises and cloud infrastructure. We have established that almost every server has some sort of internet-facing connectivity and has to be protected by antivirus and malware solutions. To complement these security solutions, we can also harden our servers and adjust local security polices and permissions. Finally, we discussed some server management techniques to restrict access to a specific set of IP addresses for SSH and RDP services.

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.
