With hundreds of tools preinstalled, the Kali Linux distribution makes it easier for penetration testers and other professionals to get started with security testing quickly. But with more than 600 tools in its arsenal, the Kali Linux can also be overwhelming. The new edition of this practical book covers updates to the tools, including deeper coverage of reverse engineering. Kali Linux is a distribution that is specifically tailored to a particular type of user— those who are interested in information security and the range of capabilities that fall under that incredibly broad umbrella. Kali Linux, as a distribution focused on security functions, falls into the desktop category, and there is no intention to limit the number of packages that are installed to make Kali harder to attack. Someone focused on security testing will probably need a wide variety of software packages, and Kali loads their distribution out of the gate. This may seem mildly ironic, considering distributions that focus on keeping their systems safe from attack (sometimes mistakenly called secure) tend to limit the packages through a process called hardening. Kali, though, is focused on testing, rather than keeping the distribution safe from attack.
