Difference between DoS and DDoS
Some of the common differences between DoS and DDoS are mentioned below.
DoS | DDoS |
---|---|
DoS Stands for Denial of service attack. | DDoS Stands for Distributed Denial of service attack. |
In Dos attack single system targets the victim system. | In DDoS multiple systems attack the victim’s system. |
Victim’s PC is loaded from the packet of data sent from a single location. | Victim PC is loaded from the packet of data sent from Multiple locations. |
Dos attack is slower as compared to DDoS. | A DDoS attack is faster than Dos Attack. |
Can be blocked easily as only one system is used. | It is difficult to block this attack as multiple devices are sending packets and attacking from multiple locations. |
In DOS Attack only a single device is used with DOS Attack tools. | In a DDoS attack, The volumeBots are used to attack at the same time. |
DOS Attacks are Easy to trace. | DDOS Attacks are Difficult to trace. |
Types of DOS Attacks are: 1. Buffer overflow attacks 2. Ping of Death or ICMP flood 3. Teardrop Attack 4. Flooding Attack |
Types of DDOS Attacks are: 1. Volumetric Attacks 2. Fragmentation Attacks 3. Application Layer Attacks 4. Protocol Attack. |
What is DDoS(Distributed Denial of Service)?
Distributed Denial of Service (DDoS) is a type of DOS attack where multiple systems, which are trojan infected, target a particular system which causes a DoS attack.
A DDoS attack uses multiple servers and Internet connections to flood the targeted resource. A DDoS attack is one of the most powerful weapons on the cyber platform. When you come to know about a website being brought down, it generally means it has become a victim of a DDoS attack. This means that the hackers have attacked your website or PC by imposing heavy traffic. Thus, crashing the website or computer due to overloading.
Example: In 2000, Michael Calce, a 15-year-old boy who used the online name “Mafiaboy”, was behind one of the first DDoS attacks. He hacked into the computer networks of various different universities. He used their servers to operate a DDoS attack that brought down several websites such as eBay and Yahoo. In 2016, Dyn was hit with a massive DDoS attack that took down major websites and services such as Netflix, PayPal, Amazon, and GitHub.
