What Is XDR?
2023 Gartner® Market Guide for Extended Detection and Response |
Read Now
Extended Detection and Response (XDR) is an evolving security category that can unify threat prevention, detection, and response. XDR solutions ingest data from tools in an organization’s security technology stack to create greater context for Security Operations Center (SOC) teams to perform faster threat detection, investigation, and response.
Key capabilities for XDR include detecting security incidents, automating response capabilities, and integrating intelligence and telemetry data from multiple sources with security analytics to correlate and contextualize security alerts. XDR solutions should include a minimum of two native security sensors and integrate seamlessly with your organization’s security ecosystem.
XDR’s primary advantages are:
- Improved, consolidated visibility: Data is ingested from siloed security solutions so that automated analysis can surface findings from large volumes of data that would otherwise depend on slow, manual processes. Solutions typically include a single point of visibility to unify findings in a single console.
- Faster investigations, more productive SecOps teams: Because XDR prioritizes threats and reduces alert volumes with analytics and correlations, teams can focus on the most critical threat events and leverage automation to address known or repeat events.
- Lower total cost of ownership: XDR vendors with a broad set of native capabilities offer cost savings by standardizing on a security stack from a single vendor, which is typically integrated out-of-the-box. Organizations with a large, best-of-breed environment can unlock data across tools and vendors with XDR solutions that offer open integrations.
XDR holds the promise of consolidating multiple products into a cohesive, unified security incident detection and response system.
Por qué necesitan las empresas seguridad XDR
Los SOC necesitan una plataforma que reúna de forma inteligente todos los datos de seguridad relevantes y desenmascare a los adversarios avanzados. A medida que los adversarios utilizan tácticas, técnicas y procedimientos (TTP) más complejos para sortear y explotar con éxito los controles de seguridad tradicionales, las organizaciones se esfuerzan por proteger un número cada vez mayor de activos digitales vulnerables, tanto dentro como fuera del perímetro de red tradicional.
Security teams have been stretched for years. With increasing work-from-home requirements, the strain on resources has been amplified. Security professionals are being once again required to do more with the same or fewer resources, and with strict budget constraints. Las empresas necesitan medidas de seguridad unificadas y proactivas para defender todo el panorama de activos tecnológicos, que abarcan endpoints heredados, dispositivos móviles, redes y cargas de trabajo en la nube, sin sobrecargar al personal ni los recursos de gestión internos.
With bad actors including “lone wolf” attackers, hacking groups, nation states, and even potentially malicious insiders constantly circling, enterprise security and risk managers are left to overcome too many disconnected security tools and data sets from too many vendors. El personal de seguridad se enfrenta a un aluvión de datos que provoca una sobrecarga de alertas, con demasiados falsos positivos y poca integración de los datos con las herramientas de análisis o respuesta a incidentes, y todo ello bajo niveles históricos de estrés operativo.
Los responsables de seguridad y gestión de riesgos de las empresas deberían considerar las ventajas en materia de seguridad y el valor en cuanto a productividad de una solución XDR.
¿Cómo funciona XDR?
XDR ingests, correlates, and contextualizes multiple streams of telemetry. XDR can also analyze Tactics, Techniques and Procedures (TTPs) and other threat vectors to make complex security operations capabilities more accessible to security teams that do not have the resources for heavily customized point solutions. XDR removes the daunting detection and investigation cycles and offers threat-centric and business context to move more quickly to a response to the threat.
XDR security provides advanced threat detection and response capabilities including:
- Detección y respuesta a ataques dirigidos
- Soporte nativo para el análisis del comportamiento de usuarios y activos tecnológicos
- Inteligencia sobre amenazas, incluida la inteligencia sobre amenazas local compartida junto con fuentes de inteligencia sobre amenazas adquiridas externamente
- Reducción de la necesidad de perseguir falsos positivos mediante la correlación y confirmación automática de alertas
- Integración de datos relevantes para una clasificación de incidentes más rápida y precisa
- Capacidad centralizada de configuración y refuerzo con orientación ponderada para ayudar a priorizar las actividades
- A centralized interface to perform investigations and respond to events
- Playbooks with automation for analysts to establish best practices
- Multi-vector, multi-vendor analytics
- Automatización y orquestación para agilizar muchos procesos del SOC
What are the benefits of XDR?
Detecting today’s advanced threats requires more than a collection of point solutions.
XDR security provides advanced threat detection and response capabilities including:
- Converting a large stream of alerts into a much smaller number of incidents that can be prioritized for manual investigation
- Providing integrated incident response options that have necessary context from all security components to resolve alerts quickly
- Providing response options that go beyond infrastructure control points, including network, cloud and endpoints delivering comprehensive protection
- Providing automation capabilities for repetitive tasks to improve productivity
- Reducing training and up-leveling Tier 1 support by providing a common management and workflow experience across security components
- Providing usable and high-quality detection content requiring little-to-no tuning
XDR improves critical SOC functions when they are reacting to an attack in their environment:
- Detection
Identify more and meaningful threats by combining endpoint telemetry with a growing list of security controls providers as well security events collected and analyzed by security information and analytic platforms. - Investigation
Human-machine teaming correlates all relevant threat information and applies situational security context to more quickly reduce signal from noise and assist with the identification of root cause. - Recommendations
Provide analysts with prescriptive recommendations to further an investigation through additional queries as well as offer relevant response actions that would most effectively improve the containment or remediation of a detected risk or threat. - Hunting
Provide a common query capability across a data repository containing multi-vendor sensor telemetry in search of suspicious threat behaviors, allowing threat hunters to locate and take action based on recommendations.
What is the difference between XDR, MDR, and EDR?
EDR (Endpoint Detection and Response) provides detection and response for endpoints. Many organizations start with EDR and progress to XDR.
MDR (Managed Detection and Response) provides detection and response as a managed service.
XDR (Extended Detection and Response) provides detection and response across multiple security controls and data sources.
Trellix XDR
Trellix Helix Connect simplifies visibility and streamlines analysis by ingesting data from Trellix native security controls across endpoint, network, data, and cloud security. The XDR solution ingests data from more than 1 billion sensors for multi-vector detection. You can also leverage non-Trellix security controls using open integrations to collect data from over 1,000 third-party sources so your team can unlock and get more from the data you already own.
Detections are surfaced using correlation across vendors and multiple threat vectors to create context. Known and routine threats are eliminated with out-of-the-box automated responses. Actionable threat Intelligence for less common or new threats is created using insights from our Advanced Research Center and network of over 1 billion global sensors. Emerging, high-impact threats are detected and prioritized using AI-driven analytics that help teams stay ahead of the evolving threat landscape.
