1. What is XDR (Extented Detection and Response) solution?

XDR, or Extended Detection and Response, is a cybersecurity solution that collects and analyzes data from multiple security sources to detect and respond to threats more effectively. It used to network visibility, behavioral analysis, machine learning, and artificial intelligence (AI) to protect digital environments.

2. How has XDR evolved within the cybersecurity landscape?

“XDR, or Extended Detection and Response, represents a significant evolution in cybersecurity, emerging from the need to address the increasing sophistication of cyber threats. The initial approach to network security focused on perimeter firewalls and Intrusion Prevention Systems (IPS) to screen incoming traffic. However, as IT and security technologies have advanced, this definition has expanded due to the complexity of modern attacks. XDR evolved from Network Traffic Analysis (NTA), combining the information derived from these tools with Artificial Intelligence (AI) capabilities to provide a more holistic and effective approach. 

3. What are the main benefits of implementing an XDR solution?

The main benefits of Extented Detection and Response (XDR) include: 

 

  • Improved visibility of the IT infrastructure.
  • Faster and more accurate detection of advanced threats.
  • Automated response to security incidents, reducing downtime.
  • Reduced complexity by consolidating multiple security tools into a single platform.
  • Increased efficiency of security personnel by automating tasks and prioritizing alerts.

4. What types of threats can XDR detect and prevent?

XDR can detect and prevent a variety of threats, including:
 
  • Suspicious activity and traffic, such as denial-of-service attacks or unauthorized access attempts. 
  • Data leaks, such as unauthorized access to confidential information or sending information to external servers. 
  • Zero-day attacks and attack patterns. 
  • Anomalous behavior and unauthorized IT transactions (shadow IT). 
  • Lateral movements within the network. 

5. How does XDR respond to threats?

XDR (Extented Detection and Response) uses AI to detect threats with high precision and respond automatically, being able to reconfigure the network, isolate infected devices, revoke credentials, and block suspicious connections. It also provides deterministic rule recommendations in the event of a suspected attack. 
 
The response XDR can include modifying the network architecture, sending updated configurations to routers, isolating compromised users, managing user permissions, and integrating with other Teldat solutions. 

6. Where can XDR be implemented?

It can be implemented in any type of corporate network because on the one hand it can collect information from any router, firewall or switch that reports its telemetry and/or events as well as from the endpoints thanks to the deployed agents.

7. What is the structure of XDR?

XDR architecture leverages a unified platform to collect, correlate, and analyze security telemetry from various sources, enabling real-time threat detection, investigation, and response.

8. How does XDR collect data?

XDR collects and correlates data to identify and analyze threats across email, endpoints, servers, cloud workloads, and networks. This enables security teams to take proactive steps to prevent and remediate threats.

9. What kind of analysis does XDR perform?

An XDR solution performs a detailed Level 7 analysis of HTTP or HTTPS application traffic. It also uses log analysis to monitor every event that happens on the network.

10. Does XDR replace antivirus?

While antivirus software protects against some known malware, XDR provide a much more robust approach to detecting and responding to some of today’s more sophisticated threats. Antivirus will provide basic protection, XDR offer seamless threat detection and response against zero day attacks.

11. Does XDR use AI?

AI is very important aspect to XDR, enabling it to analyze amounts of dat from various sources and correlate security alerts for effective threat detection and response.

12. What is data normalization in the context of XDR?

Data normalization is the process of converting data collected from different sources into a standard format that can be processed by AI models. This allows the AI to understand and analyze the data effectively.

13. How are AI models personalized for an XDR solution?

An XDR solution collects and analyzes security data across your entire IT infrastructure (email, endpoints, servers, cloud, network) to enable faster threat detection, investigation, and response.

An XDR solution allows users to use standard AI or retrain the network and deep-learning models to adapt them to their specific needs and obtain more accurate detection and alerts for each situation.

14. Does XDR collect logs?

Teldat´s XDR solution collects and aggregates security logs from devices, networks, and cloud applications, monitor user behavior, and centralize security alerts for improved threat detection and response.

15. What is Network Traffic Analysis (NTA) and how does it relate to XDR?

Network Traffic Analysis (NTA) is the process of monitoring and analyzing network traffic to detect anomalies and threats. XDR (Extented Detection and Response) evolves from NTA, integrating it with other security tools and AI capabilities to provide a more effective response.

16. How does SD-WAN relate to XDR?

Teldat uses its SD-WAN technology to increase the responsiveness of XDR, allowing the network topology to be modified. SD-WAN is a fundamental part of Teldat’s complete solution for controlling, analyzing, monitoring, and managing any network.

17. What is Teldat’s XDR solution and what makes it different?

Teldat’s XDR is an extended detection and response solution that uses artificial intelligence to increase security and network visibility. Unlike other solutions, Teldat´s XDR not only operates at the software level but also at the hardware level, allowing for a more comprehensive and effective response.
 
In addition, it adapts to the needs of each client, allowing for the personalization of AI models. 
 
Teldat can modify the network architecture, sending updated configurations to routers to eliminate threat communication and expansion mechanisms. It can also isolate access from compromised users and integrate with Active Directory to manage user permissions. 
 
It offers zero-day attack detection, response to ongoing attacks, and monitoring of user behavior. Furthermore, it integrates with other Teldat solutions, such as the Teldat´s next-generation firewall (NGFW).
