Learn Penetration Testing

By: Rishalin Pillay

Overview of this book

Sending information via the internet is not entirely private, as evidenced by the rise in hacking, malware attacks, and security threats. With the help of this book, you'll learn crucial penetration testing techniques to help you evaluate enterprise defenses. You'll start by understanding each stage of pentesting and deploying target virtual machines, including Linux and Windows. Next, the book will guide you through performing intermediate penetration testing in a controlled environment. With the help of practical use cases, you'll also be able to implement your learning in real-world scenarios. By studying everything from setting up your lab, information gathering and password attacks, through to social engineering and post exploitation, you'll be able to successfully overcome security threats. The book will even help you leverage the best tools, such as Kali Linux, Metasploit, Burp Suite, and other open source pentesting tools to perform these techniques. Toward the later chapters, you'll focus on best practices to quickly resolve security threats. By the end of this book, you'll be well versed with various penetration testing techniques so as to be able to tackle security threats effectively

Online password attacks

Just like using an automated vulnerability scanner, we can leverage tools to automatically attempt to log in to services and find valid credentials. These tools are designed to automate online password attacks until the server responds with a valid login. An online password attack can be defined as trying to log in to a live service by brute forcing credentials until a valid combination is discovered.

The trouble with online password attacks is that they can be noisy, and trigger alarms. Let's look at some of the online password attack tools that are commonly used.
