PPT-DNS AttackS Sergei Komarov

DNS Mechanism for IP ltgt hostname resolution Globally distributed database Hierarchical structure Comprised of three components A name space Servers making that name space available. DNS is the system that provides name to address mapping for the internet.. Name Space. The names assigned to machines must be unique because the addresses are unique. A name space that maps each address to a unique name can be organized in two ways: . MAN IN THE MIDDLE . ATTACK. Objectives. To understand ARP Poisoning, and how it forms MITM..
