What is a Distributed Denial-of-Service (DDoS) Attack?

What is a DDoS?

Stands for Distributed Denial-Of-Service Attack – DDoS is a type of attack that sends an overwhelming flood of requests to disrupt the normal traffic that a website or a server receives to cause havoc and make it vulnerable.

DDoS is a total nightmare for online businesses as it prevents legitimate users from accessing the site and rendering it useless. 

How to Identify a DDoS Attack?

Some signs might just be because of some technical problems from your own server but there are particular and clear symptoms you can look through to identify a potential DDoS attack.

  1. Server responding with 503 error due to service outage
  2. Unusual traffic patterns that occurs at certain hours of the day 
  3. Inability to access any website

The best sign to identify a DDoS attack would be via a network traffic monitoring and analysis which is possible with the use of firewall or intrusion detection systems. 

How to Prevent DDoS Attacks?

There’s really no specific type to prevent a DDoS attack but there are several practices you can implement that can lessen the potential of being a target. 

  1. Scale up your bandwidth – Talk about expanding the pathway, add more bandwidth if you notice an unusual amount of traffic.
  2. Learn the symptoms of a DDoS attack – Run some manual tests, DDoS attacks are pretty easy to identify especially when your website receives a stable traffic.
  3. Outsourcing DDoS protection – There are companies that specialize in scaling resources to respond to an identified DDoS attack, look for one and take advantage.
  4. Consistent monitoring of unusual activity – Monitoring traffic in real-time is the best practice you can do to identify a DDoS attack, it will help you prevent it from completely happening.
  5. Practicing good cyber hygiene – Prevention is better than cure, practice all the best security prevention such as changing passwords, using multiple authentication and so on.
