Network-based intrusion detection approaches are frequently in use to track down malicious activities. However, all approaches in the field have always been struggling to cope with increasing network speeds. This article investigates the reasons behind this fact by providing a detailed analysis of methodologies that are commonly used by Network-based Intrusion Detection Systems (NIDSs), thereby focusing on the layer of packet capturing and data filtering. Recently, the performance of NIDSs has been greatly improved by new software-based and hardware-based techniques. On the one hand, improvements and optimizations within the processing chain allow faster packet capturing and analysis, and on the other hand, the advance of multi-core processors encourages the parallelization of NIDSs, thus achieving further speedups. But especially in the area of passive data analysis with only limited control on the incoming data rate, Amdahl's law poses strict limits on parallelization and achievable processing speeds for NIDSs.
