Kali Linux Intrusion and Exploitation Cookbook

By: Dhruv Shah, Ishan Girdhar

Overview of this book

With the increasing threats of breaches and attacks on critical infrastructure, system administrators and architects can use Kali Linux 2.0 to ensure their infrastructure is secure by finding out known vulnerabilities and safeguarding their infrastructure against unknown vulnerabilities. This practical cookbook-style guide contains chapters carefully structured in three phases – information gathering, vulnerability assessment, and penetration testing for the web, and wired and wireless networks. It's an ideal reference guide if you’re looking for a solution to a specific problem or learning how to use a tool. We provide hands-on examples of powerful tools/scripts designed for exploitation. In the final section, we cover various tools you can use during testing, and we help you create in-depth reports to impress management. We provide system engineers with steps to reproduce issues and fix them.

Introduction


Previously, we covered the discovery of live servers over the network along with service enumeration. Here, we will discuss what a vulnerability assessment is. A vulnerability assessment is a process in which a tester aims to determine the services running on the ports and check if they are vulnerable. Vulnerabilities when exploited can lead us to have unauthenticated access, denial of service, or information leakage. Vulnerability assessment is essential as it gives us a holistic picture of the security of the network being tested.

In this chapter, we will be checking whether services running on open ports have vulnerabilities. It is vital to know the operating system on which the service is running since it is one of the crucial factors in reconnaissance for vulnerability discovery where remote code execution is involved. The reason is that the same services on different operating systems will have different exploits due to architecture difference. Let's talk about one vulnerability...
