A distributed denial-of-service (DDoS) attack is a malicious attempt to disrupt the normal traffic of your internet connection by overwhelming the network infrastructure with a flood of internet traffic. It can be likened to a traffic jam blocking access to the road, preventing usual traffic from arriving at its destination. For example, trying to access a cloud based service like Microsoft Office 365 or G Suite, or even accessing a simple website will become either impossible to reach or be extremely slow if you are suffering from a DDoS attack. Simply put, a DDoS attack is designed to cause disruption to internet based services.
It has become quite simple to anonymously order a DDoS attack, if you know where to go and get one. You can even select the time and duration of the DDoS attack. So long gone are the days where setting off the fire alarm is the way to cause disruption to lessons! Obviously disturbing lessons is not the only reason for a DDoS attack, it could be due to a number of other factors. For example, someone could have a particular gripe after being dissatisfied, or it could just be someone intent on causing disruption.
All LGfL internet traffic is actively monitored for suspected malicious activity, such as DDoS and even computers accessing known bad websites i.e. websites known for distributing malicious software (malware). This means that we can quickly identify a DDoS attack and apply mitigation (dropping or limiting malicious traffic) to prevent it from causing disruption to Internet based services. In most cases, LGfL have successfully applied the mitigation and prevented the DDoS attack before the school is even aware that they are suffering from it.
If you have received an alert from us about a DDoS attack being mitigated for your school, then unless we tell you otherwise, you don’t need to do anything. It is possible the mitigation may have an adverse effect on some services, such as online phone systems (VOIP), if you think this may be the case please raise a support request, and we will investigate for you.
