DOS and DDOS attack

What is DOS and DDOS attack.

DOS (Denial of Service) attack is a type of cyber attack in which a attacker flood a website or network with massive amount of traffic to disrupt its normal functioning, making it unavailable to its users.

DDoS (Distributed Denial of Service) attack is a type of attack in which multiple computers are used to flood the target network or website, making it even more difficult to defend against. The attack originates from multiple sources, making it difficult to trace and stop. 

How to Work Dos and DDOS attack.

A DOS attack works by overwhelming a target network or website with an excessive amount of traffic, essentially clogging the system and making it unavailable for legitimate users. This can be achieved in several ways, including:
1. Flooding the target with a large number of requests, such as HTTP requests to a web server, or sending a large number of packets to a network.
2. Overloading the target with a sustained stream of network traffic, such as sending a large number of packets per second.
A DDoS attack works by using a network of compromised computers, known as "bots" or "zombies", to send traffic to the target. The attacker coordinates the attack by sending commands to the bots, telling them when and how to attack the target. The large number of bots makes it difficult to defend against the attack, as the traffic comes from many different sources and is difficult to filter or block.
The goal of a DDoS attack is to disrupt the normal functioning of a network or website, making it unavailable to users for a period of time. In some cases, DDoS attacks can be used as a smokescreen for other types of cyberattacks, such as data theft or theft of sensitive information.

Types of DOS Attack.

There are several types of Denial of Service (DoS) attacks, including:

1. Flooding attacks:

 Overwhelming a network or server with too much traffic to slow it down or crash it.

2. Ping of Death:

 Sending an abnormally large ICMP packet to crash a target system.

3. Distributed Denial of Service (DDoS):

 A coordinated attack from multiple devices or systems to overwhelm a target network or server.

4. SYN Flood:

 Sending a large number of SYN packets to consume the target system's resources and cause a crash.

5. Teardrop Attack:

 Sending malformed IP packets to crash a target system.

6. Smurf Attack:

 Amplifying the traffic to a target system by sending large numbers of pings to broadcast addresses.

These are some of the common types of DoS attacks, but new types and variants continue to be developed by attackers.
