Effective threat management requires security teams to combine security analytics with the abundance of machine-generated data that is prevalent in most enterprise environments. Tools such as network traffic analysis, endpoint detection, security information and event management (SIEM), and user behavior analytics (UBA) harvest this data and reveal who is doing what in the IT environment and when and how they’re doing it. This mix of data can help uncover unknown threats, but it can also confuse some security operations professionals who are not familiar with it when the data is only partially displayed.
For instance, a network link analysis diagram — or, more simply, a list of network connections — can be very informative because it shows critical data sources, but it can also be overwhelming with its thousands of raw connections and IP addresses. Let’s take a look at some common data sources and explore why security teams really need to combine them all to generate a complete picture for detection, investigation and response.
