several IDS systems rely on &quot;learning&quot; what normal traffic looks like, then alerting you to changes in that pattern. This is often called (in the literature, or more commonly, in the marketing fluff) &quot;Anomaly Detection IDS&quot; <br />
<br />
as a subset, you can get software-based solutions (that run on hosts you wish to protect), hardware ones (which sit in the datastream, either as mirror ports or as transparent (layer 2) bridges between your protected hosts and the switch) or combinations of the two.<br />
<br />
the array of products in this space is huge :)

I've awarded the points but I was looking for an answer w/ specific product recommendataions. &nbsp;I will repost this questions under the IDS zone.

Quite happy to recommend a product if you give more detail - budget, size of network, size of internet pipe... that sort of thing.

Great - Terminal Server based network with 200 users. &nbsp;Terminal Servers are in a collocation site. &nbsp;Users in 7 remote sites connect to the collocated servers via Sonicwall VPN (Hardware). &nbsp;Internet pipe at the collocation site will be large, don't have figures yet but we can assume at least &nbsp;10mb both ways. &nbsp;Remote sites all have T1 connections. &nbsp;The budget is about 5K. &nbsp;Thanks!

I'm looking for a Network Access Control solution for an organization with 200 Terminal Server users. &nbsp;What is out there that would allow me know when the network has been compromised? <br />
<br />
Thanks!

Operating system security (OS security) is the process of ensuring OS integrity, confidentiality and availability. OS security refers to specified steps or measures used to protect the OS from threats, viruses, worms, malware or remote hacker intrusions. OS security encompasses all preventive-control techniques, which safeguard any computer assets capable of being stolen, edited or deleted if OS security is compromised, including authentication, passwords and threats to systems and programs.

OS Security

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
