Advanced Infrastructure Penetration Testing

Overview of this book

It has always been difficult to gain hands-on experience and a comprehensive understanding of advanced penetration testing techniques and vulnerability assessment and management. This book will be your one-stop solution to compromising complex network devices and modern operating systems. This book provides you with advanced penetration testing techniques that will help you exploit databases, web and application servers, switches or routers, Docker, VLAN, VoIP, and VPN. With this book, you will explore exploitation abilities such as offensive PowerShell tools and techniques, CI servers, database exploitation, Active Directory delegation, kernel exploits, cron jobs, VLAN hopping, and Docker breakouts. Moving on, this book will not only walk you through managing vulnerabilities, but will also teach you how to ensure endpoint protection. Toward the end of this book, you will also discover post-exploitation tips, tools, and methodologies to help your organization build an intelligent security system. By the end of this book, you will have mastered the skills and methodologies needed to breach infrastructures and provide complete endpoint protection for your system.

Linux hardening

In the previous sections, we discovered the required methods and tools to attack the Linux infrastructure. Now it is time to deploy safeguards and learn how to defend against these attacks and secure your infrastructure. To harden your Linux systems, you need to do the following:

  • Update Linux kernel and applications
  • Avoid using insecure services such as FTP and telnet and use SFTP and OpenSSH instead
  • Minimize the attack surface by using only the needed applications and services
  • If possible, use SELinux
  • Use a strong password policy
  • Keep an eye on faillog records
  • Harden /etc/sysctl.conf
  • Use an authentication server

Center of Internet Security (CIS) provides many hardening guides for a various number of operating systems including Linux. It is highly recommended to visit it: https://www.cisecurity.org/.
