Networks are constantly sending data to deliver messages and keep network services working, but those data packets may contain sensitive information like passwords. In this course, you'll examine how an attacker can gain access to sensitive data through packet sniffing. You'll learn how attackers can manipulate DHCP, which can allow them to then intercept target host communications. Next, you'll explore how attackers can manipulate ARP by taking advantage of the default functions of the ARP protocol. You'll move on to examine how attackers trick users into sharing personal information through DNS poisoning. Finally, you'll learn about common security controls that allow networks to communicate, while still adding layers of scrutiny, control, and obfuscation. This course is one in a series that helps to prepare you for the Certified Ethical Hacker v11 (312-50) exam.

WHAT YOU WILL LEARN

  • use network attacks to bypass network switches in order to sniff packets
    recognize the physical ways attacks can access sensitive data
    recognize the types of packets sniffing attackers can use to access sensitive data
    identify the different attacks an attacker can use to access sensitive data through network switches
    recognize how attackers can manipulate DHCP on client systems
    identify how using a rogue DHCP server can be used to intercept target host communications
    recognize and manipulate the Address Resolution Protocol (ARP) table
  • describe how to defend against attackers manipulating the Address Resolution Protocol (ARP) table
    identify how attackers can manipulate the ARP table
    recognize how attackers trick users into accessing an invalid host via DNS poisoning

    describe how to view the DNS cache on a local system
    identify security controls that can be employed to add layers of security that can derail many sniffing attacks
    recognize common security controls and settings that can be added to derail many sniffing attacks
