XDR security meaning will be discussed in detail in this article. XDR Security is designed to help security teams:

  • Identify sophisticated or hidden threats
  • Track threats across multiple system components
  • Improve detection and response speed
  • Investigate threats more effectively and efficiently

What is XDR Security?

XDR security was designed as an alternative to point security solutions that were limited to a single layer of security or could only perform unresponsive event correlation. It is the advancement of solutions like Endpoint Discovery and Response (EDR) and Network Traffic Analysis (NTA).

These shift-specific tools, while still useful, tend to generate more alarms, take more time to investigate and respond to events, and require more maintenance and management. In contrast, XDR consolidates tools and enables security teams to work more efficiently.

How does XDR security work?

Here are three main features of XDR solutions:

  1. Analysis and detection

XDR security is based on a series of analyzes to detect threats. Below are some of the commonly included analytics features:

  • The analysis of internal and external data traffic ensures the detection of malicious insiders and compromised credentials as well as the identification of external attacks. By monitoring and analyzing internal and external traffic, XDR can detect a threat even if it has already bypassed the perimeter of your system.
  • Integrated Threat Intelligence: Integrates information about attack methods, tools, sources and known strategies across multiple attack vectors.
  • Machine learning-based detection – includes supervised and semi-supervised methods that identify threats based on behavioral benchmarks. Machine learning technologies enable XDR to detect zero-day and non-traditional threats that signature-based methods can bypass.
  1. Inquiry and response

The following are some of the features included in XDR that can help investigate and respond:

  • Correlation of Alerts and Related Data: Tools can automatically group related alerts, create attack schedules from activity logs, and prioritize events. This helps teams quickly pinpoint the root cause of an attack and predict what an attacker might do next.
  • Centralized User Interface (UI): Allows analysts to investigate and act on events from the same console. This speeds up the response time and simplifies the documentation of responses.
  • Response Orchestration Capabilities: Enables response actions directly through XDR interfaces as well as communication between tools.
  1. Dynamic and flexible deployments

Here are some of the features that will help achieve this goal:

  • Security orchestration: Possibility to integrate and use existing controls for uniform and standardized reactions.
  • Scalable storage and compute power: XDR uses scalable cloud resources to meet your data and analytics needs. This ensures that historical data, useful for identifying and investigating advanced persistent threats or other long-term attacks, remains available.
  • Improvement over time: The inclusion of machine learning ensures that over time, solutions become more effective at detecting a wider range of attacks. Combined with the inclusion of threat intelligence, this helps ensure that the maximum number of threats is detected and prevented.

Benefits of XDR Security

XDR security can provide the following benefits:

Improved prevention capacities

The inclusion of threat intelligence and adaptive machine learning can help solutions implement protection against a wide variety of attacks. In addition, continuous monitoring and automated response can help block a threat as soon as it is detected to prevent harm.

Granular visibility

In combination with network and application communication, provides comprehensive user data for an endpoint. This includes information about access permissions, applications used and files viewed. With complete insight into your system, including locally and in the cloud, you can identify and block attacks more quickly.

Effective response

Robust data collection and analysis enables you to record an attack path and reconstruct the actions of attackers. This provides the information needed to locate the attacker wherever he is. It also provides valuable information that you can apply to strengthen your immune system.

More control

Includes the ability to blacklist and whitelist data traffic and processes. This ensures that only actions and approved users can enter your system.

Better productivity

Centralization reduces the number of alerts and increases alert accuracy. This means fewer false positives to search. Since XDR is a unified platform and not a combination of multipoint solutions, it is also easier to maintain and manage and reduces the number of interfaces that security must access during a response.

How XDR security differs from other security solutions

XDR security differs from other security tools in that it centralizes, standardizes, and correlates data from multiple sources. These features allow for more complete visibility and can reveal less obvious events.

Collecting and analyzing data from multiple sources, XDR security can better validate alerts. This helps reduce the time teams could waste on excessive or inaccurate alerts. According to Gartner, this improves the productivity of security teams and enables faster and more automated reactions.

Also, because the alert sources are natively contained in the XDR solution, there is no need for integration and maintenance required to monitor alerts in a SIEM.

How does XDR work with SIEM?

Security Information and Event Management (SIEM) is used in most security operations centers as a central repository for security event data and as a means of generating alerts from security events. XDR can extend SIEM by leveraging SIEM data and combining it with data from point solutions integrated with the XDR platform.

XDR security can go even further with SIEM. For example, if a SIEM platform generates an alert, XDR can do it automatically instead of forcing security analysts to manually access endpoint security systems or cloud systems for further investigation. It can combine SIEM data with forensic data from endpoints and cloud resources and create a comprehensive attack history. Analysts can understand and respond to the full extent of the threat immediately.

XDR security also enables advanced analysis. SIEM is traditionally based on statistical correlation rules, while XDR introduces AI-based analysis that creates behavior benchmarks and identifies anomalies based on these benchmarks.
