Cybersecurity Blue Team Toolkit

By: Nadean H. Tanner

Overview of this book

As reports of major data breaches fill the headlines, it has become impossible for any business, large or small, to ignore the importance of cybersecurity. Most books on the subject, however, are either too specialized for the non-technical professional or too general for positions in the IT trenches. Thanks to author Nadean Tanner’s wide array of experience from teaching at a University to working for the Department of Defense, the Cybersecurity Blue Team Toolkit strikes the perfect balance of substantive and accessible, making it equally useful to those in IT or management positions across a variety of industries. This handy guide takes a simple and strategic look at best practices and tools available to both cybersecurity management and hands-on professionals, whether they be new to the field or looking to expand their expertise. Tanner gives comprehensive coverage to such crucial topics as security assessment and configuration, strategies for protection and defense, offensive measures, and remediation while aligning the concept with the right tool using the CIS Controls version 7 as a guide. Readers will learn why and how to use fundamental open source and free tools such as ping, tracert, PuTTY, pathping, sysinternals, NMAP, OpenVAS, Nexpose Community, OSSEC, Hamachi, InSSIDer, Nexpose Community, Wireshark, Solarwinds Kiwi Syslog Server, Metasploit, Burp, Clonezilla and many more.

Network Mapping

Network mapping uses a process to discover and visualize assets by actively probing them. Nmap sends both TCP and UDP packets to a targeted machine. These are called probe packets. A probe packet is a packet used in an active tool to collect information on a network segment of interest. Data is collected after sending those probe packets that hop from node to node and asset to asset, which returns that information to Nmap.

If you were to scan 65,536 ports on every single machine in your ecosystem, this scan could take an astronomically long time and is really unnecessary. Occasionally, you may hear someone refer to a host discovery scan as a ping scan. In Nmap, you could choose to skip the ping itself and use other targeted methods to find the active hosts on your network.

Network environments are all different; therefore, host discovery needs are going to be very different. The hosts on your network serve multiple purposes, and from a priority standpoint, not all assets...
