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.

XDR 보안이 기업에 필요한 이유

SOC에는 연관된 모든 보안 데이터를 하나로 모으고 지능형 공격자를 발견하는 지능적인 플랫폼이 필요합니다. 공격자들이 기존 보안 제어를 성공적으로 회피하고 익스플로잇하기 위해 더욱 복잡한 전술, 기술, 절차(TTP)를 사용함에 따라 조직은 기존 네트워크 경계 안팎에서 점점 더 늘어나는 귀중한 디지털 자산을 보호하는 데 어려움을 겪고 있습니다.

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. 기업은 인력 및 인하우스 관리 리소스의 부담을 가중하지 않으면서도 기술 자산, 늘어나는 레거시 엔드포인트, 모바일, 네트워크, 클라우드 워크로드의 전체 환경을 방어할 통합된 사전 예방적 보안 조치가 필요합니다.

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. 보안 인력은 경고가 넘치는 데이터의 바다 속에서 너무 많은 오탐과 분석 도구 또는 인시던트 대응의 데이터 통합 부족으로 어려움을 겪고 있으며, 운영 스트레스는 사상 최고 수준을 기록하고 있습니다.

기업 보안 및 위험 관리 책임자는 XDR 솔루션의 보안 이점과 생산성 가치를 고려해야 합니다.

XDR은 어떻게 작동하나요?

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:

  • 표적 공격 탐지 및 대응
  • 사용자 및 기술 자산 행동 분석 기본 지원
  • 공유 로컬 위협 인텔리전스와 외부에서 획득한 위협 인텔리전스 소스를 결합하는 기능을 포함하는 위협 인텔리전스
  • 경고의 상관 관계를 자동으로 분석하고 확인해 오탐을 추적할 필요성 감소
  • 더 빠르고 정확한 인시던트 분류를 위한 연관 데이터 통합
  • 활동 우선순위 지정을 돕는 가중치 지침을 갖춘 중앙 집중식 구성 및 강화 기능
  • A centralized interface to perform investigations and respond to events
  • Playbooks with automation for analysts to establish best practices
  • Multi-vector, multi-vendor analytics
  • 많은 SOC 프로세스를 간소화하기 위한 자동화 및 오케스트레이션

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.
