Extended Detection and Response (XDR)
Extended Detection and Response or XDR is becoming more important for threat hunting reporting and searching for the root cause whenever a breach is discovered.
This article will help you to understand XDR and to discover why the use of this tool can be a necessasity for your organization.
What is Extended Detection and Response?
Extended Detection and Response platforms enables you to detect, investigate, and respond to multi-stage threats across all key vectors, in the shortest time.Â
- Get complete visibility beyond the endpoint : Detect & stop adversaries as they move
- Maximize user efficiency : Optimized workflows accelerate investigation and response
- Compatible with your existing cybersecurity tools and technology investments
During this article we will address Sophos XDR since, this tool is the most extended version of XDR Kappa Data Provide
Extended Detection and Response platform
Accelerate detection, investigation and response
Sophos XDR includes tools and capabilities designed to maximize the efficiency of security analysts and IT admins. AI-guided investigations enable you to quickly understand the scope and cause of an incident and minimize the time to respond
AI-priotized detections over all surfaces
Investigate and hunt threats at speed
Powerful search tools, including pre-canned query templates, enable you to find the data you need faster without needing to be an SQL expert
Collaborative case management
Automatic case creation enables rapid investigation, with comprehensive case management tools for collaboration with other team members.Â
MITRE ATT&CK Framework mapping
The MITRE ATT&CK framework is a universally accessible, continuously updated knowledge base for modeling, detecting, preventing and fighting cybersecurity threats based on cybercriminals’ known behaviors.Â
All known techniques of hackers are registered in this framework. All of these techniques are also registered in the Sophos XDR tools, on top of the techniques that are out of the scope of this framework but discovered by their own threat hunting team.Â
Sophos XDR Surfaces
Extended Detection and Response, or XDR, is the successor of EDR or Endpoint Detection and Response. This extension of surfaces has become necessary because hackers constantly look on the Internet for flaws in different types of devices and networks in order to “log-in” into the network.Â
Sophos XDR Included Integrations
Sophos offers its own solutions like Endpoint Security, Network Security, Cloud Security and Email Every device is connected towards 1 central management platform, which is called Sophos Central.Â
In this overview, you will see as well the Microsoft Security Suite as the Google Security Suite included, what makes Sophos XDR quite interesting for organizations.Â
Sophos has its own ecosystem of different devices, as the graphic shows below.Â
Sophos XDR External integrations
In many cases, companies have a network that exists out of different brands for firewalls, switches, Access Points, cloud directories, identity platforms, etc..Â
In order to implement XDR threat hunting, metadata of these different devices needs to be integrated into the data lake of Sophos. For integrating the metadata of these devices, Sophos uses Application Program Interfaces (API’s) for retrieving this data and order this data in their alerting system.Â
Using Sophos XDR
Sophos XDR lets you investigate detected threats (threat graph – see below) and search for new threats or security weaknesses. It also lets you monitor devices and fix issues remotely.Â
Within the Threat Analysis Center, you can find the most XDR features
When you drill down you can track the root cause of a certain threat in order to stop the detection and eliminate the possibility a hacker can proceed with its activities
