"It's the Unicorn we've been looking for!"
This was the response I got the other day when I was explaining to a customer the benefits of looking back at packets before and after they pass through an active, inline device and a packet capture or forensics tool.
Simply put, how else will enterprise networks have real-time knowledge of an attempted attack, as well as the ability to look back and see how the packets were altered or dropped?
Historical lookback aka before & after, is solution that uses hybrid bypass TAPs with monitoring ports that allow both security tools, such as next-gen firewalls and intrusion prevention systems to share packets with multiple monitoring tools such as network packet capture, forensics, deep packet inspection, etc.
EdgeLens® Garland Technology's hybrid bypass TAP and In-line Security Packet Broker provides identical network traffic streams, both through the active, inline security tools (IPS/NGFW/WAF), and to the network packet capture, forensics, deep packet inspection and/or lawful intercept tools.
Because all devices see the same traffic, it is easy to correlate events generated by the active, in-line device with the PCAP data which is captured and indexed within the out-of-band packet analysis tools.
Historical Lookback (before/after) Benefits
- Real time events correlation
- Change verification
- Root cause analysis
Once a breach or critical event is detected, it's imperative to facilitate a real-time security incidence response, including retrieval of full sessions and other detailed context around those critical events. Extracted PCAP files may be further analyzed by a variety of out-of-band tools for security forensics.
This solution can be deployed with most vendors network analyzer tools and security tools, the tools are independently managed through the EdgeLen's interface - the key here is that all the tools share the same packets via the identical network stream.
