- Distributed denial of service attack in this attack multiple systems which are infected by trojan, are used to target a single system causing a denial of service attack(dos) .By slowloris you can do DDoS attack .As Slowloris is a tool of kali linux .
Attacks involving multiple computers or other devices all targeting the same victim are considered DDoS attacks due to their distributed design. Of the two, DDoS attacks are more prevalent and damaging in the modern Internet.
A DoS or DDoS attack is analogous to a group of people crowding the entry door of a shop, making it hard for legitimate customers to enter, thus disrupting trade.
A distributed denial-of-service (DDoS) attack occurs when multiple systems flood the bandwidth or resources of a targeted system, usually one or more web servers.Such an attack is often the result of multiple compromised systems (for example, a botnet) flooding the targeted system with traffic. A botnet is a network of zombie computers programmed to receive commands without the owners’ knowledge.When a server is overloaded with connections, new connections can no longer be accepted. The major advantages to an attacker of using a distributed denial-of-service attack are that multiple machines can generate more attack traffic than one machine, multiple attack machines are harder to turn off than one attack machine, and that the behavior of each attack machine can be stealthier, making it harder to track and shut down. These attacker advantages cause challenges for defense mechanisms.
