With the constant onslaught of new attacks and emerging threats, one might say that every day is an exciting day in the security operations center (SOC). But arguably, today’s SOC teams are in the midst of one of the most compelling and transformative shifts in how we detect and respond to cybersecurity threats. Innovative security organizations are working to modernize the SOC with extended detection and response (XDR) platforms that bring the latest advancements in artificial intelligence (AI) to the defensive effort.
XDR solutions correlate security telemetry across security domains, including identities, endpoints, software-as-a-service apps, email, and cloud workloads, to provide detection and response capabilities in a unified platform. As a result, security teams using XDR have more visibility across the enterprise than ever before. But that is only half the story. The combination of this unprecedented visibility with an AI-powered SOC assistant can enable security teams to operate at the speed necessary to turn the tables on would-be attackers.
In this rapidly evolving environment, innovative security organizations that want to confidently take advantage of today’s AI capabilities and lay the groundwork to seamlessly adopt tomorrow’s innovations require a thoughtful, future-aware implementation strategy.
XDR Breadth Matters, Even If You Start Small
Unlike traditional automated detection and blocking solutions that often rely on a single indicator of compromise, XDR platforms use AI to correlate cross-domain security signals that take the entire attack into account and identify threats with a high degree of confidence. The increased fidelity that AI brings to the table improves the signal-to-noise ratio and results in fewer false positives to manually investigate and triage. Notably, the broader the dataset the AI is operating on, the more effective it will be; as such, XDR’s native breadth is critical.
Ideally, an effective XDR strategy will identify and account for the highest risk areas, cybersecurity maturity, existing architecture and tools, and budgetary constraints, among other factors. While implementation should be phased to minimize operational disruption, organizations must also consider how to best achieve the widest breadth of XDR coverage to fully unlock AI’s capabilities.
Build AI-Confident Teams
The goal of AI is not to replace humans in your SOC but rather to empower them. If your team does not have confidence in the tools they use, they will not unlock the full value of the platform. Minimizing false positives, as discussed above, will help build trust among users over time, but it is also essential to provide operational transparency so there is always an understanding of where data is coming from and what actions have been taken.
XDR platforms must give SOC teams complete control when investigating, remediating, and bringing assets back online when they want them. Tightly integrating threat detection and automatic attack disruption capabilities with existing workflows will streamline triage and provide a user-friendly view of threats and remediation actions across the infrastructure.
Forward-thinking organizations can take it a step further and look to generative AI to upskill the entire SOC team via guided investigation tools, script analysis, and query assistance.
Stay Threat Intelligent
Indicators of attack and indicators of compromise are constantly evolving. An effective, long-term XDR strategy will address the ongoing need for rapid analysis and continual vetting of the latest threat intelligence. Implementation roadmaps should address how to support the integration of timely threat intelligence and build in flexibility to scale or augment teams when complex incidents demand more expertise or support.
As more organizations look to invest in XDR and AI to improve their security operations, a thoughtful, future-aware approach to implementation will help them more effectively leverage today’s AI capabilities, while also being ready for tomorrow’s innovations. After all, successful organizations won’t just look to AI to get them ahead of attackers. They will plan investments in AI that keep them ahead.
