Introduction
Computer security is a protection that safeguards the system, hardware, software and
networks from all the malicious attacks. The need of computer security is increasing day by
day because cyber-crimes are also increasing. Thus, it is necessary to protect all the
information as organisations and enterprises completely rely over network for keeping their
information private (Schwartz, 2017). The role of computer security is to maintain
confidentiality, availability and integrity of information. The vulnerabilities and attacks are
increasing day by day. One such attack that is considered in this report is distributed denial
of service. It is an attack that makes the resources and services unavailable from the valid
user. DDoS attack is difficult to detect as in this system is fooled from the attacker by
sending huge amount of traffic to the victims computer. In this report, one real life example
of DDoS that is operation ababil is discussed.
An overview on DDoS
Distributed denial of service is an attack that has penetrated in the real world. It
makes many web applications and services unavailable from the user for a time slot. It is
caused due to many infected computers on the internet that are under the control of hackers
(Alieyan, Kadhum, Anbar, Rehman & Alajmi, 2016). It basically targets servers and do not
allow legitimate users to access the information. Theses attacks take place silently as even
the owners of computer are not aware that their system is being access by third party
(Alieyan, Kadhum, Anbar, Rehman & Alajmi, 2016). This attack is carried by increasing
eth traffic over the web or flooding it with many requests in order to degrade the service.
