What is Retrospective Network Analysis?
Retrospective network analysis allows you to quickly browse backwards through massive amounts of network traffic to view breaches and anomalies as they happened, within the context of other activity on the network. Now you can avoid the labor-intensive step of re-creating problems to troubleshoot them. Traditional packet capture gives administrators insight into networks via packet-level decode and analysis. While these tools are useful in managing mid- to enterprise-level networks, using them to provide administrators enough information to solve subtle or sporadic problems is difficult. RNA acts like a 24/7 surveillance camera—it is far easier to find the culprit using a stored video of the crime rather than one photograph.
