DoS & Its Types
Denial of Service (DoS) occurs whenever a website stops to offer services. Denial of services is the result of some attack or presence of too many online visitors on a specific site.
There are many kinds of attacks that disable a system. In some cases, peer-to-peer software is used to corrupt the firmware. Among all types of attacks, Distributed Denial of Service (DDoS) attack is most common. DDoS brings a lot of traffic to a website that is impossible to handle. Networked computers are used by hackers to bring a flood of traffic to disturb business continuity. As website is designed to handle a limited number of customers’ requests at a time, it crashes when flooded with too much traffic.
DDoS Attacks Frequency
DDoS attacks occur on frequent basis. According to Wikipedia, DDos occurs on an average of 28 times per hour. What is more ironical is an increase in the number of attacks on regular basis.
Who are DDoS Attackers?
There are many reasons that compel hackers to use distributed denial of service attack. One cannot pin down exact reasons and who the attackers are. It is believed that DDoS attacks are used by competitors against a business as deceitful tactic.
Objectives behind DDoS Attacks
Attackers use DDoS attacks to get ransom money. Companies are warned to pay an amount, otherwise their system will crash. Once company pays the given amount, it becomes the target of hackers for long term. On the other hand, companies that refuse to pay the ransom suffer due to hindrances in business continuity and downtime, which means to shell out for system recovery and their business reputation.
Sometimes, DDoS attacks are the result of a protest. When hacker groups have conflict with the actions of certain groups, they attack their websites to show reaction. There are many hackers that just use these attacks for the sake of pleasure or to cause trouble for others.
Companies Affected by DDoS Attacks
Steam, Sony Playstation Network, and Xbox Live Network of Microsoft are some of the significant companies that are affected due to DDoS attacks. Side by side large scale companies, small companies are harassed by these attacks because they do not have preventive measures to mitigate the effects.
Unintentional DDoS Attacks
DDoS attacks can be accidental. It may happen that a lot of visitors have found something interesting on a website (video, picture or article) and visit the site at the same time. Website might not be ready to handle an increase in number of visitors, therefore, the system stops to give service any more.
DDoS Attacks are Expensive
Nuestar reported* that DDoS attacks cost more than $100K in an hour for almost 29% businesses. Due to these attacks, customer support centre was affected more than any other department.
In a nutshell, businesses must have an influential plan for DDoS and business continuity. Best practices should be used to reduce the number of DDoS attacks. As a result, the affects of downtime on clients and business can be controlled.
