More and more UK online businesses are subject to DDoS attacks from cyber criminals who are motivated by profit to take a business offline. Most DDoS attacks are carried out by cyber criminals however a growing number of attacks are also carried out by state-sponsored government agencies including China or Russia who are attacking the UK’s digital infrastructure every day. We are no longer just talking about some hackers in hoodies we are talking about cyber warfare which could have some very serious consequences on our daily lives.
What is a DDoS (distributed denial-of-service) Attack?
A distributed denial-of-service (DDoS) attack is an attack in which multiple compromised computer systems attack a target, such as a server, website or another network resource, and cause a denial of service for users of the targeted resource. The flood of incoming connection requests or malformed packets to the target system forces it to slow down or even crash and shut down, thereby denying service to legitimate users or systems.
Types of DDoS Attacks
A volumetric attack overwhelms a website or network with a flood of traffic, creating enough volume to destabilize a network’s bandwidth or crash a site. A common deployment method for a volumetric attack is a botnet, or zombie army. A botnet consists of thousands of computers that have been hacked and are being used without owners’ awareness. The hacker seizes control of the infected army of computers and directs them to assault the desired target. If thousands of computers and even hundreds of thousands are all trying to access the same site at once, relentlessly submitting requests, that can crash the system, causing a DDoS outage.
Application Layer Attacks
The internet is based on seven vertical layers; each layer uses certain protocols to transmit information and traffic over a network, which is why attackers want to target various protocols and layers of the network model. A lot of hackers target the SMTP and HTTP application layers which manage web browsers and email services. These type of DDoS attacks can be difficult to detect and are becoming more sophisticated. The aim of an application layer attack is not to overwhelm resources with a flood of requests, but rather to exhaust resources by consuming too much.
These attacks are designed to consume server resources and those of other communication devices. These attacks operate by sending a barrage of open requests, which servers and other communication devices answer and then wait for a packet response. The requests are generated by fake IP addresses, so when your devices query back, it never goes anywhere. This causes the devices to have open resources, with less availability to answer real requests. If your servers are busy answering bogus requests, they don’t have the capacity to respond to legitimate traffic. Using protocols like TCP/IP, attackers use a flood of requests that effectively shut down your network resources
