Let Us Discuss New Approaches to Enhanced Threats

Monitoring-Response and Logging

Many organizations tend to a new approach to enhanced threats as enhanced attack vectors increase from endpoints to networks to the cloud: Extended Detection and Response (XDR)

What is Extended Detection and Response (XDR)?

Extended Detection and Response is an enhanced version of Endpoint Threat Detection and Response (Endpoint Detection and Response–EDR)

When EDR aggregates and associates activities across multiple endpoints, XDR extends detection beyond endpoints to provide detection, analytics, and response across endpoints, networks, servers, cloud workloads, SIEM, and more.

It provides a unified, single screen view across multiple tools and attack vectors. This enhanced visibility supplies contextualization of these threats to assist in prioritization, research, and quick fix efforts.

Extended Detection and Response automatically collects and correlates data across multiple security vectors, and facilitates faster threat detection. Therefore, security analysts can respond quickly before the scope of the threat expands. Ready-to-use integrations and preset detection mechanisms across a wide range of products and platforms help improve productivity, threat detection and forensics techniques.

What is the difference between XDR and Security Information and Event Management (SIEM)?

SIEM gathers large volumes of log data across the organization and analyzes and stores them. SIEM began its journey with a very broad approach and collects available log and event data from virtually any source across the organization to be stored for various use cases. They contain searching among telemetry sources for governance and compliance, rule-based pattern matching, heuristic/behavioral threat detection such as UEBA, and IOCs or atomic indicators.

However, SIEM tools require a lot of fine-tuning and effort to implement. Moreover, security teams can also be overwhelmed by multiple alerts from a SIEM and lead the Security Operations Center (SOC) to ignore critical alerts. In addition, even if a SIEM captures data from dozens of sources and sensors, it is still a passive analytical tool that gives warnings.

Extended Detection and Response platform aims to solve the challenges faced by the SIEM tool to effectively detect and respond to targeted attacks and includes behavior analysis, threat intelligence, behavior profiling and analytics.

What Is Difference between XDR and SOAR?

Security Orchestration Automation and Response-SOAR platforms are used by mature security operations teams to create and run multi-stage “playbooks” that automate actions in an API-connected ecosystem of security solutions. In turn, XDR will enable cybersecurity tools ecosystem integrations via Marketplace and provide mechanisms to automate simple actions against 3rd party security controls.

SOAR is complex, costly and requires a fairly mature SOC to implement and maintain partner integrations and playbooks. XDR is intended to be 'SOAR-lite': It is a simple, intuitive, zero-code solution that provides actionability from the XDR platform to connected security tools.

Why Does XDR Establish Gravity and a New Approach?

XDR replaces silo security and helps organizations address cybersecurity issues through a unified perspective. XDR collects and compiles data from a wider range of sources by enabling faster, deeper and more effective threat detection and response than EDR with a single raw data repository including information in the whole ecosystem.

XDR supplies greater visibility and context to threats, otherwise, events that could not be dealt with before will reach a higher level of awareness allowing security teams to correct and mitigate further impact and minimize the scope of the attack.

A typical ransomware attack roams the network, an email comes to the inbox and then attacks the endpoint. Addressing security is an disadvantage for organizations considering them independently. When user access is disabled and suspicious account security are breached, XDR integrates different security controls to provide automated or one-click response actions across enterprise security products such as forcing multi-factor authentication, blocking inbound domains and file hashes, and more, and provides them in user or prescriptive response engine logically using special rules.

XDR collects and compiles data from a wider range of sources, enabling faster, deeper, and more effective threat detection and response than EDR with a single raw data repository containing information in the whole ecosystem.

This comprehensive visibility provides several benefits, including:

  • Reducing the Mean Time to Detection (MTTD) by correlating data sources.
  • Reducing Mean Time to Investigate (MTTI) by speeding up prioritization and reducing research and coverage time.
  • Reducing the Mean Time to Response (MTTR) by enabling simple, fast and relevant automation.
  • Increasing visibility across all security products.

Moreover, XDR helps reduce the manual workload on security analysts thanks to Artificial Intelligence (AI) and automation.

An XDR solution can proactively and quickly detect complex threats, improve security or SOC team productivity, and deliver a massive increase in ROI for the organization.
