Abstract
According to one aspect, a method includes coupling first and second security units in series between first and second networks. The first security unit obtains packets from the first network, and the second security unit obtains the packets from the first security unit. The first security unit includes first logic arranged to provide security. The second security unit includes second logic arranged to provide security. The method also includes configuring the second security unit in a bypass mode such that the second logic does not provide security, and obtaining a first packet from the first network via the first security unit. The first packet is identified as secure by the first logic. Finally, the method includes providing the first packet from the second security unit to the second network by passing the first packet through the second unit without using the second logic to provide security.
