In addition to the prevention of data theft, effective defence against DoS attacks is essential for online shops.

What makes DoS attacks easier is that it is easy to create a fake source address. It is extremely difficult to track the attackers because attacks usually come from anonymous addresses that are impossible to trace.

“However, there are effective means to prevent DoS attacks. What is important is that the attack is stopped before it accesses the company's connections or servers.” uses a DNA service which detects any suspicious traffic. DoS attacks are blocked in DNA's backbone network.

The number of DoS attacks increases around Christmas and during other holiday seasons.

The reason for this is not known. It is possible that there are hackers who are seeking to raise as much attention as possible for their attacks during the otherwise quiet days. Another possible reason is that, during holidays, hackers have more time to spend on their illegal activities.
