Unlike endpoint detection and response, which collects only endpoint security telemetry, XDR collects data from native and third-party security domains including endpoints, cloud workloads, identities and more, then aggregates and applies relevant context so security teams can effectively triage and prioritize threats.
At a time when organizations lack visibility and continue to expand into complex IT environments, XDR aims to shed light on threats across the organization so they can be addressed before they become bigger problems.
While XDR tackles the enterprise security challenge of threat detection across a diverse attack surface, it can also create new issues.
Below are the top challenges for businesses looking to implement XDR:. Technology Integration: As security teams have invested in new tools in an attempt to bolster detection and prevention capabilities, the challenge of providing a consistent, centralized view for SOC analysts to rapidly understand, triage and remediate issues has quickly grown.
Integration and centralized management challenges typically drive alerts, including false positives, and increase staff workloads when bringing XDR into an environment.
XDR implementation can be complicated, costly and time-consuming.
Effective Strategy: An XDR strategy should include specific requirements to align with your business' security needs.
Once XDR is in place, an XDR management plan can help ensure you're getting the full value out of the platform.
The data streamed into an XDR platform may come from SaaS applications, custom-built applications, security tools and other resources.
Do - Ensure Proper Integration: XDR relies on the proper integration of security tools including EDR, network detection and response and security incident and event management systems to work effectively.
The process of implementing and using XDR will have fewer obstacles if the platform integrates with your existing IT and security stack.
Test an XDR platform before deployment, so you can address any potential issues before doing a full rollout.
XDR guides these remediation efforts with detection information so security teams can take action to contain threats and prevent future incidents.
If your organization can't optimize its use of XDR with in-house staff, look to managed XDR services to reduce complexity and cost while optimizing resources and improving threat detection.
An XDR platform needs accurate and high-quality information to effectively detect and respond to threats.
Don't - Overlook Proven Expertise: While XDR does the heavy lifting of processing and analyzing data, it still requires a skilled person to handle alerts, respond to incidents and ensure XDR is properly implemented and running.
Failure to plan for future scale and capacity can lead to poor performance, resource limitations and lower effectiveness in your XDR platform.
Relying too much on autonomous capabilities in an XDR platform can result in false positives, which leave security teams sifting through low-fidelity alerts.
XDR is evolving to become a critical component of security strategy for organizations of all sizes, across all industries - but how XDR looks and functions may be different depending on the requirements and security stack of each business.
Before jumping into XDR implementation, take a step back, consider your existing security tools and speak with board members, stakeholders and potential partners to determine which approach will work best.
