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.

DDoS attacks

DDoS attacks occurs when compromised devices flood the network traffic of a targeted system. This type of attack threatens the availability of the system. When it comes to DDoS attacks, there are four attack vectors:

  • Volumetric attack: This floods the victim using the organization's bandwidth.
  • Fragmentation attacks: This attack exploits datagram fragmentation mechanisms by preventing the reassembling back of fragmented data packets. It is also called Teardrop attack.
  • TCP state-exhaustion attack: This attack exhaust the number of concurrent connections supported by web servers, load balancers and firewalls.
  • Application layer attack: This uses application weaknesses to disable the service. As shown in the following graph, an attacker exploits compromised hosts also known as zombies to perform a DDoS attack against his target.
