Kali Linux in Action. Audit of Information Systems Security

This book discusses methods for bypassing security systems of network services and penetrating open information systems. Information security, like much in our world, is a coin with two sides. On one side, we conduct audits, look for ways to penetrate,... and even apply them in practice, while on the other, we work on defense. Penetration testing is part of the normal lifecycle of any IT infrastructure, allowing a true assessment of potential risks and uncovering hidden problems.
Can hacking be legal? Of course, it can! But only in two cases — when you hack information systems that belong to you or when you hack an organization's network with which you have a written agreement to conduct an audit or penetration tests. We hope that you will use the information in this book only for legal hacking of information systems. Please remember the inevitability of punishment — any illegal actions may result in administrative or criminal liability.
You will sequentially go through all the steps necessary to conduct an audit of information systems security and penetration testing: from general concepts, reviewing standards and necessary actions before conducting an audit, to methods of penetration into an information system and establishing oneself within it. Each chapter of the book is supported by real examples and contains practical information on the application of various methods.

The book is aimed at readers with experience in the field of information technology and those familiar with the operation of main network services on both Linux and Windows platforms, and will be especially useful for system administrators, IT security specialists, and anyone wishing to link their career to information protection or auditing activities.In the second, amended and revised edition, the information has been completely updated to reflect modern realities.
