External Bypass Switches: A Better Inline Security Tool
When a network monitoring device such as an IPS is deployed inline in a network, it is vital to ensure that traffic continues to flow in all circumstances, even if the IPS loses power, so that mission-critical business applications remain available. A bypass switch is an excellent solution that keeps traffic flowing, for failsafe implementation of inline security tools.
This paper examines the value of an external bypass switch, over and above that of an internal bypass switch. Bypass switches improve the overall solution reliability, increase application availability, provide better instrumentation, and add the convenience and cost savings of remote monitoring and control.
