CEH v11: Sniffing & 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 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.
