DDOS ATTACKS AND PROTECTION AGAINST THEM

Abstrak

A Denial of Service (DoS) attack is an attempt to harm a targeted system, such as a website or application, by making it unavailable to normal end users. Typically, attackers create a large number of packets or requests that overload the target system. An attacker uses many compromised or controlled resources to carry out a distributed denial of service (DDoS) attack. In general, DDoS attacks can be divided into types based on the level at which the attack occurs in the Open Systems Interconnection (OSI) model. Attacks on the network layer (layer 3), transport layer (layer 4), presentation layer (layer 6), and application layer (layer 7) are the most common.
