Intrusion Detection & Prevention Systems Deployment Case
An Intrusion Detection System is a tool that detects unwanted attempts at accessing, manipulating or disabling a computer system through the network infrastructure. In addition, Intrusion Prevention Systems allow for the device to intercept or send packets back to the live network in an attempt to stop threats on the network.

Why do you need to use an access technology solution with your IDS/IPS?
Because these tools need to be installed in-line, they can become a source of network downtime. When the device fails or needs to have maintenance performed on it, the entire network needs to be brought down to perform these fixes.

Network Critical solutions for IDS/IPS Deployments
By using virtually inline or V-Line taps in a network, system administrators can isolate appliance failures and inherited appliance software issues by deploying their otherwise inline network tools using a hardened traffic access point. V-Line taps actively monitor the directional flow of data through a network appliance in both directions, and allow the tap to maintain live network continuity while having the option to actively bypass an inline appliance, should the device lose network link or traffic flowing in either direction through the inline appliance.

In the event of an inline appliance failure, V-Line traffic access points detect these occurrences while maintaining live network link, and will actively bypass the faulty appliance. Similarly, if traffic ceases flowing in either direction through an inline appliance, V-Line taps can detect such an anomaly and actively bypass inline appliance software failures.
