ArcSight this week announced it would acquire NAC vendor Enira Technologies to augment ArcSight's security information management software with Enira's automated network response technology.

The coupling could, in theory, equip enterprise IT customers with tools to detect security threats, identify the source and take automated actions to protect the network.
