Distributed DoS (DDoS) attacks amplify DoS attacks in that a large number of compromised systems
coordinate collectively to flood the victim, thereby causing denial of service for users of the targeted
systems. Common forms of DoS/DDoS attacks include SYN flood attacks, smurf attacks, land attacks,
viruses, and worms.
Attackers Family
It is important to identify the attackers responsible for all computer and network abuse, as this identification
assists in characterizing the attack and the level of damage it can cause. It is also useful to track them down by
understanding their motives and actions. Attackers can be classified in three broad categories:
Script kiddies (aspiring hackers): These are amateur members of the attacker community with no
deep knowledge of the technology. They use readily available programs and tools developed by others for
the purpose of intrusive activities. They are movtivated to test limits and to be noticed.
True hackers: This group of attackers is well versed and has thorough knowledge of the technology with
well-developed competence to perform intrusions. Hackers in this category are motivated by the pursuit of
recognition and notoriety. They often see hacking as a challenge and a competition.
