SIEM
solutions so far seem to be too much focusing on security offerings they
propose and they are not offering solid redundancy and disaster solutions.
From architectural perspective, there should be a redundancy
option at all layers of the solution architecture. SmartConnectors being the first layer of SIEM interaction with
source systems provide a nice redundancy options with “Failover Destination” configuration setting available both for HP ArcSight Logger and HP ArcSight ESM.
For each log processing system, SmartConnector
provides a primary destination and a failover destination. As soon as SmartConnector
process discovers that logs are not successfully received by the primary
destination, they are redirected to the failover destination. Preemption also
exists meaning that from the moment primary destination becomes online logs are
redirected back to the primary destination.
More detail
about the configuration can be seen in the video below.
