This category of attack attempts to create congestion by consuming all the available bandwidth between the target and the larger Internet. The target machine responds to each connection request and then waits for the final step in the handshake, which never occurs, exhausting the targetвЂ™s resources in the process. A good example is the SYN Flood attack which exploits the TCP handshake by sending the target many TCP вЂњInitial Connection RequestвЂќ packets with spoofed source IP addresses. Protocol attacks utilise weaknesses in Layer 3 and 4 of the protocol stack to render the target inaccessible. A single HTTP request is cheap to execute on the client side but can be resource intensive for the target server as it often must load multiple files and run database queries in order to create a web page.ДЄlso known as state-exhaustion exploits, these attacks cause a service disruption by consuming all the available state table capacity of web application servers or intermediate resources like firewalls and load balancers. They categorise the attacks based on their effect on the various components of an internet network connection as described in the conceptional OSI вЂ7 LayerвЂ™ Framework.ДЇocused on the OSI Layer 7, these attacks target the layer where web pages are generated on the server and delivered in response to HTTP requests. The DDoS Mitigation specialist, Cloudflare, has an excellent summary of different types of DDoS attack. It is estimated there are currently 100,000 memcached servers currently sitting exposed online with no authentication protection. Memcached is a caching system designed to optimise websites that rely on external databases. The GitHub DDoS attack did not use botnets but employed the use of unprotected memcached servers. The Dyn attack used malware called Mirai which created a botnet out of compromised Internet of Things (IoT) devices such as cameras, smart TVs, radios, printers and baby monitors.

Because each bot is a legitimate internet device, separating the attack traffic from normal traffic can be very time consuming. Each bot then sends multiple requests to the target server causing it to overload and stop working. The hacker sends the target IP address of the web server to the bots.

The attacker has full remote control over the group of bots, which is called a botnet.

A bot or web robot runs software applications which are simple, automated and repetitive in their action. The most common DDoS attack aims to gain control of a network of online devices (computers, mobile phones, IoT) by infecting them with malware and turning them into bots. The barrage peaked at 1.2 terabits per second and created devastating disruption for AirBnB, Netflix, PayPal, Visa, Amazon, The New York Times and Reddit. Peak incoming traffic was measured at a rate of 1.3 terabytes per second (Tbps) with data packets being sent at a rate of 126.9 million per second.Д¬oming a close second was the attack on Dyn, a major DNS provider, in October of 2016.

GitHub, the code management service provider, suffered the largest reported DDoS attack in February 2018. Criminal hackers using DDoS attack often target sites or services hosted on high-profile web servers of banks, e-commerce and credit card payment gateways. The flood of incoming network traffic will come from many sources and makes the attack impossible to stop by blocking a single source. In some cases, a companyвЂ™s recovery time can last months and end up costing tens of thousands of pounds.ДЄ distributed denial-of-service (DDoS) cyber attack targets and disrupts web servers by sending them an overwhelming number of requests from a very large number of external computers or IP enabled devices. E-commerce businesses are particularly vulnerable and can suffer significant loss of reputation and customer confidence.

Companies of all sizes suffer downtime that leads to financial loss from reduced sales and increased operational costs. Modern DDoS attacks are designed to disrupt and terminate the normal activity of web servers.

Using survey data from internet service providers, they estimate that 57% of global enterprises and 45% of data centre operators experienced internet bandwidth saturation due to a DDoS compromise. The Arbor Networks 2018 Worldwide Infrastructure Security Report confirms that a total of 7.5 million DDoS attacks were executed in 2017. Distributed denial-of-service (DDoS) cyber attacks remain a significant threat to any organisation that uses a web site or web application to deliver its services.
