It should come as little surprise to most security professionals that keeping pace with the evolution of threat actors has become harder and harder. Maintaining visibility into the threat landscape and on top of external risk vectors is more than a matter of incorporating more point solutions. It takes a concerted risk-based approach, where the tools you choose are just one leg of the tripod.
In a report released earlier this summer, Gartner analysts offer three recommendations for fostering an environment of risk-based threat detection, investigation, and response that includes a deeper understanding of your organization’s risk profile by more than just the security team. Below are our three main takeaways from the Gartner® 3 Ways to Apply a Risk-Based Approach to Threat Detection, Investigation, and Response.
Takeaway 1: Better alignment and clearer objectives
The need to break silos between teams is a time-honored proposition that holds even more weight now than it ever has. Gartner suggests creating a quorum of business leaders from across the entire organization to be read into the state of your security and the needs going forward. Prioritize accurate and regular reporting of security metrics to build trust and create a consistent atmosphere of effective transparency. This group should be diverse, with decision makers and specialists from core departments. According to Gartner, the goal should be to:
“Allow the business to be part of the conversation and therefore champions of the capability, elevating the security program to a business function rather than an I&O underpinning.”
Takeaway 2: Integrated risk context
Giving incident responders as much information (and the right information) they need to quickly and efficiently respond to threats requires a complex layering of risk information that includes prioritization for the businesses key assets. Gartner recommends the use of cyber-risk information elements directly implemented into an IR program, layering in asset-based and business-risk information that gives responders the context they require to appropriately triage what can often be a large volume of data.
Gartner says:
“Incident responders should have as much information at their disposal as needed to be effective at finding a needle in a haystack.”
Takeaway 3: Fully enriched business context from jump
Too much information can often be as detrimental to a security team as too little. SecOps needs to have access to the right information in the most efficient way possible in order to find the signal through the noise. Gartner recommends reducing investigative delays through enriched information complete with business context (see, they are all connected). This transparency can be accomplished in part through SIEM, CAASM, and threat intelligence tools and a robust vulnerability management program, but it is worth noting that Gartner prioritizes providing the right information, not the most information; hence, utilizing the right tools.
All three of these recommendations combine to create a risk-based approach to detection, investigation, and response that Gartner says: “...organizations can expect to create measurable efficiency gains in threat detection and increase their ability to respond to threats in a timely manner.”
