What is DDos Attack ?
Compromised PCs, or “bots,” are formed into groups called “botnets” and are used as weapons by cyber-attackers to launch various forms of cyber attacks. These attacks range widely from DDoS to identity theft and clandestine intelligence gathering operations.
During Distributed Denial of Service attempts, attackers launch attacks using different techniques including HTTP, HTTPS, ICMP, SYN Floods, UDP Floods, DNS Request Floods, GET Floods, and others. The attack components are often used in combination, and range in size from a few hundred megabits per second (Mbps) to over 80 gigabits per second (Gbps). Increasingly sophisticated attacks are based around application requests at Layer-7.
Normally, DDOS consists of 3 parts . One is the Master ,Other the slave and atlast the victim. The master is the attack launcher ie the person/machine behind all this,sound’s COOL right . The slave is the network which is being compromised by the Master and Victim is the target site/server . Master informs the compromised machines, so called slaves to launch attack on the victim’s site/machine. Hence its also called co-ordinated attack.
