When investigating a network attack you not only need the answers and you need them fast, you want the full story. Today’s attackers are stealthy, creative, and opportunistic, probing networks and exploiting any weak spots they find. To be successful, you need to match their creativity when analyzing your data. The story’s in there—your challenge is finding the evidence you need to pinpoint the source or extent of the attack and begin remediation as soon as possible.
At its heart, network forensics is detective work. There’s a mystery that needs solving, and the story is in your network data. Maybe the software development manager noticed that the CEO checked out the latest build in the source code repository at three in the morning. Maybe a user reported weird behavior on their laptop. The reasons for these types of behavior could be meaningless—maybe the CEO had a bout of insomnia—or they could mean everything: a network breach. Network forensics is about looking for clues and gathering evidence in network data to answer these questions.
Unfortunately, there’s no shortage of data coming from your network infrastructure: logs, alerts, and even dashboards. It can be overwhelming. For years the network security industry has focused on providing more security intelligence from all of this data, and in some cases there have been successes. But as the level, severity, and complexity of the attacks increases, organizations are looking for a better, smarter way, and are now moving beyond the simple search and dashboard intelligence provided by security event platforms.
In network forensics investigations, there’s a lot of data to sift through. Even the most stealthy and careful attacker can’t help but leave telltale clues of their behavior in your data as they infiltrate your network and spread their attack. Detecting these behavior patterns within the data is critical. Many network forensic tools simply mine data while offering little in the way of analysis capabilities or visibility into the data. You need a solution that helps you find the patterns that lead to answers you can use in your incident response, not just more questions.
21CT LYNXeon enables curious investigators to take a look at their data and find the intentionally hidden, non-obvious relationships between different events and data points. These are the patterns of network behavior that indicate an attack. Sure, LYNXeon has innovative and intelligent data modeling and search methods. More importantly, though, LYNXeon helps you find patterns in your data that might otherwise go undiscovered—patterns that reveal the insights that lead to successful investigative outcomes.
