DDoS Attack
What is a Denial Of Service Attack?
•A denial of service attack (DOS) is an attack through which a person can render a system unusable or significantly slow down the system for legitimate users by overloading the resources, so that no one can access it.
•If an attacker is unable to gain access to a machine, the attacker most probably will just crash the machine to accomplish a denial of service attack.
Types of denial of service attacks
There are several general categories of DoS attacks.
Popularly, the attacks are divided into three classes:
→bandwidth attacks,
→protocol attacks, and
→logic attacks
What is Distributed Denial of Service Attack?
•An attacker launches the attack using several machines. In this case, an attacker breaks into several machines, or coordinates with several zombies to launch an attack against a target or network at the same time.
•This makes it difficult to detect because attacks originate from several IP addresses.
•If a single IP address is attacking a company, it can block that address at its firewall. If it is 30000 this is extremely difficult.
