CEH v12: Sniffing and Poisoning

Skillsoft issued completion badges are earned based on viewing the percentage required or receiving a passing score when assessment is required. 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.
