CEH v12: Sniffing and Poisoning

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 Dynamic Host Configuration Protocol (DHCP) which can allow them to then intercept target host communications. Next you;ll explore how attackers can manipulate Address Resolution Protocol (ARP) by taking advantage of the default functions of ARP. You;ll move on to examine how attackers trick users into sharing personal information through domain name system (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 v12 (312-50) exam.
