Hoi,
Ik zag deze voorbijkomen en dacht dat het wel interessant is voor hier (met name om hoe dit nu te voorkomen als je NTP servers hebt die publiekelijk bereikbaar zijn)

Over the last couple of weeks you may have been hearing about a new tool in the DDoS arsenal: NTP-based attacks. These have become popular recently and caused trouble for some gaming web sites and service providers. We'd long thought that NTP might become a vector for DDoS attacks because, like DNS, it is a simple UDP-based protocol that can be persuaded to return a large reply to a small request. Unfortunately, that prediction has come true.
