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.

Sniffing attacks

Sniffing is the process of intercepting network traffic by turning the network interface card (NIC) to promiscuous mode, in order to be able to sniff the transmitted data. There are two types of network sniffing – active and passive sniffing:

  • Passive sniffing: This occurs at hub devices or switches without injecting any additional packets.
  • Active sniffing: This is done by injecting Address Resolution Protocol (ARP) packets into the network. The following are some active network sniffing attacks:
    • MAC flooding—this is the process of flooding the CAM table with random data until it is full
    • Switch port stealing

These two previous attacks could be avoided by allowing only one MAC address on the switch port and implementing port security.

  • ARP Poisoning: ARP is used to resolve MAC addresses. An attacker could forge the ARP requests to flood a switch...
