The cost of carrying out this type of attack is relatively cheap and depends on the duration and strength (Mbps, Gbps or Tbps) from the attack.
Instead, according to the Web Analytics Company, the annual Neustar DDoS attack report, businesses can lose up to US $ 2.5 million in detecting and reducing the effects of each DDoS attack.
The same report stipulates that about 40 percent of respondents know attacks on their networks from their customers.

The result of this is whammy double: the brand becomes less reliable and brand image applies to throws.
In fact, a study by Corero raced reputation damage as the worst effect of the phenomenon.
The company using the Internet of Things (IOT) puts itself at a greater risk of DDoS attacks, with relatively new technology being disturbed by insecurity and therefore it is a soft target for hackers.
The research found that 98 percent of the IoT device traffic was not encrypted so that it leaked personal and confidential data.

Failure to provide a service level agreement (SLA) to the client is another major consequence of the DDoS attack on a business.
Prevent DDoS attacks.
While the company invests in cyber examination and IT security testing to protect from cyberattack, hackers too, becomes smarter. Therefore, the prevention of DDOs attacks is more challenging now than in the past.
Below we discuss ways of business and companies can reduce the risks associated with DDoS.
Traffic scrubbing
Github uses the traffic of rubbing as the DDoS mitigation method to fight attacks on the system in February 2018.
By using this technique, the traffic that is destined for the target IP address is transferred to the data center, where unwanted traffic (from attackers) is rubbed.
Business can route traffic through the center of scrubbing or use it when they are under the DDoS attack.
The scrubbing center is distributed throughout the world and has DDoS protection equipment and a large bandwidth to handle traffic attacks weighing 300 Gbps or more.
Content delivery network (CDN)
CDN refers to the distribution of web servers throughout the world.
If the Web server is targeted by the DDoS attack, CDNs help compensate for the burden by distributing traffic floods to other servers that are more localized.
Because traffic is distributed to the server network, volumed attacks, unless the attacker can produce enough traffic to flood the server, usually ineffective.
CDNs will ensure that business websites are still online, while customers do not see differences in their user experience.
However, CDN must have available bandwidth to handle high traffic volume, measured in megabits, gigabit and terabit per second.
CDNS protects applications from attack layer attacks such as cross site scripts, remote file inclusion and SQL injection.
ISP protection.
With DDoS a major IT security problem, the business switches to their internet service provider for protection.
ISPs have the capacity to reduce spam into the system and thus facilitate the burden on the server using a technique known as the black romp.
ISPs usually have access to blackhole filters that are triggered remotely, abbreviated as RTBH, to help their customers filter DDoS attacks. This technique helps avoid abnormal traffic before entering the protected network.
Either independently or after requests from customers, the ISP can act in the following two ways:
Blackhole traffic at the source
Blackhole traffic to the target
By building traffic in the source (attacker), the ISP stops spam traffic to its customer's web server and allows legitimate (or normal) traffic to pass.
This type of blackholing may not be possible if the address of the attacker's source is unknown.
If the Blackholes ISP traffic to the target, normal and abnormal traffic to the customer's web server will drop.
