This paper proposes an unsupervised clustering technique for data classification based on the K-means algorithm. The K-means algorithm is well known for its simplicity and low time complexity. However, the algorithm has three main drawbacks: dependency on the initial centroids, dependency on the number of clusters, and degeneracy. Our solution accommodates these three issues, by proposing an approach...
Recognized as one the most serious security threats on current Internet infrastructure, botnets can not only be implemented by existing well known applications, e.g. IRC, HTTP, or Peer-to-Peer, but also can be constructed by unknown or creative applications, which makes the botnet detection a challenging problem. Previous attempts for detecting botnets are mostly to examine traffic content for bot...
