our figures about DDoS
attacks in Luxembourg in 2021.

The risk of being confronted with DDoS attacks is more and more important and attempts are increasing. In this context POST has decided to publish in full transparency its figures concerning the DDoS volumetric attacks recorded on its Backbone in Luxembourg.

What is a DDoS attack ?

A Distributed Denial of Service (DDoS) attack is an attempt to make an online service on internet unavailable by overwhelming it with traffic from multiple sources. These attacks are always more complex and enterprises cannot protect themselves against these attacks. They have to trust their Internet Service Provider. Indeed, traditional security systems such as Firewalls, DNS do not stop all DDoS attacks. Only a dedicated service will protect your IT infrastructures and your Internet services, by mitigating your traffic: rejecting illegitimate Internet traffic and filtering legitimate traffic.

What are the consequences ?

In case of a DDoS attack, the impacts are numerous for your company:

  • Business interruption
  • Loss of income
  • Loss of notoriety

POST established this definition in order to differentiate alerts from attacks:
Several alerts can form one attack. If the break between the different alerts is no longer than 70 minutes, then we count these alerts as one attack. But if the break is longer than 70 minutes between the alerts, then we count these alerts as different attacks.
