From EDR to XDR: Understanding GravityZone Sensors

From EDR to XDR: Understanding GravityZone Sensors

In today's ever-evolving digital landscape, cybersecurity is paramount. With the rise of cyber threats, organizations need robust solutions to protect their sensitive data and digital assets. Bitdefender's GravityZone sensors are at the forefront of this battle, providing real-time monitoring, detailed analysis, and the power to safeguard against potential threats. In this article, we'll explore how these sensors work and their critical role in the world of cybersecurity.

Sensors: The Guardians of Cybersecurity

In the Bitdefender GravityZone ecosystem, sensors are the unsung heroes. They serve as vigilant sentinels, constantly monitoring security events and identifying potential threats. These sensors gather data from various sources such as endpoints, cloud platforms, networks, and identity management systems. By doing so, they create a comprehensive view of security events, enabling quick detection, containment, remediation, and recovery.

The XDR Event Correlation Engine, powered by these sensors, plays a crucial role. It identifies relationships between alerts and combines them into incidents. This information is vital for understanding the scope of an attack, identifying its origins, and taking rapid action to mitigate threats.

Evolution from EDR to XDR

The journey from Endpoint Detection and Response (EDR) to Extended Detection and Response (XDR) has been driven by the need to gather and analyze diverse security information. While EDR focuses primarily on endpoints, XDR expands its scope to ingest data from various sources. This expansion allows for a more comprehensive understanding of attack processes and enables the identification of more effective response strategies.

Sensor Implementation: Tailored to Your Needs

Implementing sensors is crucial for the effectiveness of the GravityZone platform. Depending on the sensor type and your organization's requirements, there are different implementation methods:

  • Endpoint Sensors: Deployed through the BEST installer.
  • AWS Sensor: Configured through backend connections between GravityZone and AWS with proper permissions.
  • Azure Sensor: Configured similarly to AWS Sensor, with Azure AD registration required.
  • Active Directory Sensor: Monitors Active Directory through backend connections and requires the BEST agent with EDR on each domain controller.
  • Azure Active Directory Sensor: Detects events in Azure Active Directory and utilizes backend connections.
  • Microsoft Intune Sensor: Monitors Microsoft Intune and requires Azure AD registration.
  • Office 365 Sensor: Monitors Office 365 through backend connections.
  • Google Workspace Sensor: Monitors Google Workspace through backend connections.
  • Network Sensor: Requires an additional virtual appliance configured in TAP mode, capturing network traffic for analysis.

In multi-tenant deployments, administrators can configure sensors throughout the organization and manage them from a single console, streamlining the process of incident detection and response.

Endpoint Sensors: Uncovering the Unseen

Endpoint sensors, also known as incident sensors, monitor endpoint activities comprehensively. They track running processes, network connections, registry changes, and user behavior. Machine learning algorithms and prevention technologies are used to identify advanced threats or in-progress attacks.

These sensors excel at detecting subtle actions that signal a network breach or the presence of attackers. For example, they can spot attackers using legitimate tools for malicious purposes, such as PowerShell processes or the Sysinternals suite. Moreover, they can identify multiple entry vectors employed by attackers, such as spear phishing, web server vulnerabilities, or social engineering tactics.

Cloud Sensors: Protecting Your Cloud Assets

With the increasing reliance on cloud services like AWS, Azure, and Google Cloud, the need for cloud sensors is critical. GravityZone Cloud Sensors extend security monitoring and detection capabilities to these cloud platforms, ensuring the protection of valuable data and assets from potential threats.

Identity Sensors: Safeguarding User Identities

Identity sensors continuously monitor user identities, access controls, and authentication activities within an organization's network or cloud environment. They leverage advanced analytics and machine learning algorithms to detect potential security threats or anomalies related to identity and access management.

Single-Click Response: Empowering Security Teams

The GravityZone XDR Identity Sensor offers powerful response capabilities, allowing security teams to take meaningful action directly from the GravityZone management console. This includes disabling Active Directory accounts or forcing password resets, enhancing incident response efficiency.
