Distributed Denial of Service protection detects and surgically removes DDoS attack traffic from your network without disrupting key services. Provisioned at the network edge, it matches up to the sophistication and scale of cyber attacks in all forms and sizes and ensures immediate action is taken to mitigate threats.
Our Managed Security Service utilises world-leading technologies to provide tiered levels or protection for your critical applications and infrastructure, ensuring we have the right solution to suit your organisation’s requirements.
A Distributed Denial of Service (DDoS) attack is defined as a malicious attempt to disrupt the normal traffic of a service, network or server by overloading its related infrastructure with traffic. Similar to a traffic jam, this prevents normal traffic from getting through and therefore makes it difficult to separate from the malicious traffic.
DDoS attacks are dangerous because not only do they disrupt normal services, but they are also increasingly used to mask more sinister cyberattacks such as data breaches. This can have significant financial, operational and reputational repercussions on your organisation.
There are some proven DDoS mitigation methods that work to protect against attacks. As well as ensuring computer-end users are using secure passwords, personal firewalls and anti-virus software, DDoS protection techniques can include avoiding unclear or unauthorised email attachments, risky website URLs, or unreputable download sites. It is also important to implement regular software updates and ensure all data is backed up.
It is essential to continually monitor the health of your network and identify any vulnerabilities that may leave your organisation susceptible to DDoS attacks. Some key steps you can take to mitigate attacks include buying more bandwidth which ensures you have enough to handle spikes in traffic that may result from malicious activity, and spreading your servers across multiple data centres to distribute traffic and make it harder to compromise.
There are also simple hardware configuration amends that can help mitigate attacks, such as configuring a router to block external DNS responses, and anti-DDos hardware that can be deployed to protect against flood attacks or similar attempts. It is also important that your DNS servers utilise redundancy and deploy a protection appliance to block abnormal traffic.
Generally, DDoS attacks can be divided into three types: volume based attacks, protocol attacks and application layer attacks. Each is designed to make an online service unavailable to users by temporarily disabling the hosting server. Volume based attacks include UDP floods and ICMP floods and aim to saturate the bandwidth of an attacked site, while protocol attacks consume server resources and include SYN floods and fragmented packet attacks. Application layer attacks crash a server and include low-and-slow attacks.
