An intrusion detection system (IDS) is capable of identifying the source of traffic, filtering the traffic to classify it as either safe or suspect and then applying sophisticated detection techniques such as stateful pattern recognition, protocol parsing, heuristic detection or anomaly detection either singularly or in combination based on the traffic type. In a network environment, each traffic source is provided with at least one IDS sensor that is dedicated to monitoring a specific type of traffic such as RPC, HTTP, SMTP, DNS, or others. Traffic from each traffic source is filtered to remove known safe traffic to improve efficiency and increase accuracy by keeping each IDS sensor focused on a specific traffic type.

A compressor for waveforms having at least two waveform states separates the waveform samples into waveform state sample vectors for each waveform state. Waveform state encoders encode the waveform state sample vectors separately to provide compressed waveform data. The waveform state encoder selects waveform state pattern vector and associated codes to represent the waveform state sample vectors. The differences between samples of the waveform state sample vector and waveform state pattern vector are calculated and encoded. Encoding can be lossless or lossy. The waveform state pattern vectors and other parameters for compression are determined during a training period. The waveform state encoders detect features in the waveform state sample vectors and waveform state pattern vectors that are useful for common oscilloscope measurements. Typical waveform states include level states and edge states.

A system for performing input and output operations to and from a processor in which interrupts for I / O operations are conditionally generated internally rather than externally by (Super State TM ) microcode residing in a separate address space in memory in an area protected from the user. A (superblock) register in the processor points to the Super State area in memory. If the Super State mode is turned on, an interrupt is generated within the processor whenever the control table allows. The interrupt directs the processor to the register and hence to the Super State code. By way of example, the Super State code controls power and access to the port, decides whether to put the interrupt in memory and emulate the I / O, and counts access to the port. The invention provides a processor with the flexibility of performing I / O operations to and from memory and / or to a peripheral or to trap an interrupt into a new operating environment for device emulation. Device emulation and monitoring is allowed without considerable program overhead. The invention provides a powerful, efficient I / O control system which can change or adapt in response the changing demands of an application program.
