BotMiner: Clustering Analysis of Network Traffic for Protocol- and Structure-Independent Botnet Detection

Botnets are now the key platform for many Internet attacks, such as spam, Distributed Denial-of-Service DDoS, identity theft, and phishing. Most of the current botnet detection approaches work only on specific botnet Command and Control (C&C) protocols (e.g., IRC) and structures (e.g., centralized), and can become ineffective as botnets change...

Bandwidth Estimation: Metrics, Measurement Techniques, and Tools

In a packet network, the terms "Bandwidth" or "Throughput" often characterize the amount of data that the network can transfer per unit of time. Bandwidth estimation is of interest to users wishing to optimize end-to-end transport performance, overlay network routing, and peer-to-peer file distribution. Techniques for accurate bandwidth estimation are...

A Technique for Dynamic Updating of Java Software

During maintenance, systems are updated to correct faults, improve functionality, and adapt the software to changes in its execution environment. The typical software update process consists of stopping the system to be updated, performing the update of the code, and restarting the system. For systems such as banking and telecommunication...

A State-Space Approach to SLA Based Management

Large complex systems are often composed of several interacting, independent components. In many such systems, although the behavior of the constituent components is well characterized, the behavior that results from interaction between such components is more or less intractable; making it hard for the administrators to efficiently manage the system...
