Because the original deployments of IDS were just passive data collectors there was no impact on networkperformance from adding new signatures so the data base grew and grew and the logs IDS generated grew and grew to the point where even a mid-size organization would receive millions of alerts a day.
True, if you live behind a corporate firewall, have fast wired connections, and not a tremendous need for performance(network lags can be detrimental to data-hog applications like video editing, software development, and 3D modeling), then you can make do with a Chromebook-like endpoint.
Potential participants include users and producers of systems and components for telecommunications carriers, Internet exchanges, financial markets, data centers, multiple system operators (MSOs) networking systems, high-performance computing, network storage and servers and other individuals interested in future IEEE 802.3 Ethernet wireline standards.
