DDOS attack
DDOS is defined as a distributed denial of services which is one of the most
common cyber-crimes. It is a part of DOS attack and the rate of this crime is increasing
very fast and in the year 2017 thousands of users were suffered from this cyber-attack.
There are various other types of security attacks occur, for example, ransomware,
wanna cry, malware and botnet attack (Bhushan, & Gupta, 2018). The main purpose of
this report is to understand the concept of the DDOS attack and how hackers attack
consumer private networks.
On February 28, the year 2018 Github organization has faced the problem of
DDOS attack which is a very biggest attack in the history of cyber-crimes. At that time,
this online community was suffered around 1.35 terabits per second of unwanted
signals due to which their services were not working properly. This attack impact on
the performance of the Github website and security team of this community identified a
large number of traffic signals in their personal servers (Bhuyan, Bhattacharyya, &
Kalita, 2015). There are many hackers they use complex algorithm, and botnet process
to detect personal information of any computer networks. In this attack, the hacker uses
flooding and malware servers and produce unauthorized signals to block the networks
of Github. In this modern generation many customers use various third-party
applications which are developed through malware and due to that users lose their
privacy and data. The management team of Github detected this cyber-crime and they
communicated with Akamai prolexic to reduce the problem of DDOS. Akamai prolexic is
an information security community which provides various security programmes to
consumers and organization. They produced a computer service to mitigate the incident
of DDOS in Github with the help of routing traffic signals and it also blocked or encrypts
malicious signals. It is observed that the data wires of Github are not able to handle a
large number of traffic signals but they designed their infrastructure to control five
times of traffic signals from last attacks. Around 10 minutes website was not worked
properly and it was suffered around $300 USD because hackers first block their serves
and after that, they demand money to restore their personal information (Hussain,
Hussain, Dillshad, Nafees, & Azeem, 2016).
