Effective Decision Support in Near-Real Time

INDUSTRY VIEW by Allen Avery, AutomationWorld.com With increased data throughput and higher data resolutions, historians have also become a foundation for plant asset management initiatives, thanks to new visibility and trending tools. Today’s historians also support techniques, such as complex event processing, which can analyze multiple streams of plant data in real time to identify and diagnose [...]

NAME
PRADS - Passive Real-time Asset Detection System SYNOPSIS
prads -i eth1 -v DESCRIPTION
PRADS is a Passive Real-time Asset Detection System. PRADS employs digital fingerprints to recognize services on the wire, and can be used to map your network and monitor for changes in real time. Real-time passive traffic analysis will also let you detect assets that are just connected to the network for a short period of time, since PRADS can glean useful information from every packet. PRADS aims to be the one-stop-shop for passive asset detection, and currently does MAC lookups, TCP and UDP OS fingerprinting as well as client and service application matching and a connection state table. Various output plugins include logfile and FIFO and make PRADS a use- ful replacement for p0f, pads and sancp. PRADS was built from the ground up for a small footprint and modern networks with IPv6 and gigabits of throughput. OPTIONS
