Of all foundational elements for information security, logging requires far more care and feeding than its fellow cornerstones such as encryption, authentication or permissions. Log data must be captured, correlated and analyzed to be of any use. Due to typical log volume, software tools to manage log events is a must-have for businesses of any size.
Traditionally, log events have been processed and handled using security information and event management (SIEM) tools. SIEM systems at the minimum provide a central repository for log data and tools to analyze, monitor and alert on relevant events. SIEM tools (and data analysis capabilities) have evolved more sophisticated capabilities such as machine learning and the ability to ingest third-party threat data.
What is managed detection and response?
Traditional SIEM falls short in the follow-up steps once an event or incident rises to a certain level of concern. This is where managed detection and response (MDR) comes in. Just like the sheer volume of log data makes it inefficient and ineffective for humans to review log files manually, so too the scale of modern datacenters (with virtual machines and application containers) makes responding to every threat with a human resource impractical. MDR systems take log events and correlate them with an end goal of identifying incidents that your security team should investigate and takes initial steps to mitigate threats and in many cases perform a root-cause analysis.
A key distinction between MDR and other related technologies (SIEM, endpoint detection and response [EDR], or extended detection and response [XDR]) is that MDR is managed, meaning it is more than just a system, it’s a service. MDR is often billed as an extension of an in-house security operations center (SOC), which means that your IT security staff is augmented by individuals with expertise in both the MDR platform and related skills such as incident response, root-cause analysis, and threat hunting. The benefit to having a service-based response team is that you can more effectively respond to incidents without dramatically impacting your workforce.
This service-related component means you need to consider service-level agreements (SLAs), response times, and other benchmarks related to service performance when selecting an MDR solution. Organizational needs will vary wildly based on company size, industry compliance requirements, and other key topics. Likewise, one of the biggest impacts to your MDR budget will be the associated FTE full-time equivalent (FTE) costs, so finding that sweet spot will be a critical decision point.
