What is Managed Detection and Response?

Defining Managed Detection and Response (MDR)

Managed Detection and Response (MDR) is an outsourced cyber security service that meseculds technology, analytics, and human skills. The service sprout from the need for organizations to continuously monitor, detect and respond to threats. Some facets of the MDR services include: –

  • The service solution typically concentrates on threat detection, monitoring, and response rather than compliance.
  • The service leverages provider tools and other technology stacks for effective threat hunting and detection.
  • The service heavily relies on human resources for monitoring networks round the clock.
    Security event management and advanced analytics play a crucial role in managed detection and response services.
  • Service providers enable incident validation and remote response, containing security risks and vulnerabilities.

An MDR remotely inspects, detects, and respond to various threats detected in your enterprise environment. The endpoint detection and response (EDR) tool deliver the required visibility into the events at the endpoint. Mainly, threat intelligence, analytics and forensic information get fed to the hands of analysts to perform the needed risk reduction strategies.

Core capabilities of MDR services?

Threat hunting

Attackers always try their best way to blindfold the eye of their targets. Automated tools and technologies are significant here, but what makes threat hunting in MDR more vital is the addition of the human element. Considering all those intrusive and stealthy threats, they leverage their skill and expertise to catch those threats that bypassed the automated layer.

  • Prioritization

Here is another capability that differentiates MDR from other EDR services. For an enterprise, knowing what to address first is keen. There may be several alerts, and you require the right prioritized plan to move forward. Managed prioritization, otherwise known as managed EDR, uses human intelligence and automated techniques to remove false alerts. The product marks a picture clear view of high-quality threats.

  • Exploration

Adding additional context to security alerts help the enterprise understand threats in a more swift manner. The investigation capability of MDR can give a precise idea of what exactly took place, when it took place, how far the impact traversed and what was affected. Therefore, a deeper range of the threat surface could make way for effective response plans.

  • Actionable advice

MDR provides actionable advice to enterprises to manage and remediate found threats based on criticality. This advice can shape up from low to high critical response plans. It could be as simple as isolating a specific system or completely eliminating a threat. Likewise, it can also include ways by which a threat could get down to minimal severity, enabling a fast recovery.

  • Remediation

Recovery is all that matters when a threat is at its highest authority. Some ways that managed MDR puts on to restore and reverse the condition is by eliminating malware, ceasing intrusions, and removing persistence mechanisms. It ensures that your organizational posture gets back to a healthy state and no further exploitation happens.

Advantages of MDR security services

What happens when you detect threats faster? In fact, you can respond to threats more effectively. That is the core principle of MDR, reducing the existing impact of an event. While looking through the benefit gate of managed detection and response services, enterprises can witness: –

  • 24/7 monitoring eye of expert SOC analysts
  • Extended detection coverage using investigation capabilities
  • Improved threat intelligence based on gathered indicators and behaviours of global insights
  • High maintainability and log management
  • An improved security posture
  • A state of enhanced resiliency to potential threats
  • Getting rid of rogue systems
  • Eliminating lurked and highly sophisticated threats
  • A guided response driving endpoints back to a healthy state
  • Redirecting staff from reactive and repetitive tasks to other strategic goals

Differences between MDR and other Endpoint Protection Solutions

Let us first shoot the differentiating elements of EDR with respect to MDR. It typically records and saves behaviour and events on endpoints and supplies them to the automated and analysis systems. On detection of flaws, these go to the security team for human investigation. However, security analysts present in enterprise in-house teams often lack the required skills, time, and resources to utilize EDR systems. An MDR addresses this scenario by blending analytics, threat intelligence and the human factor.

Next, how does managed security services providers (MSSPs) differ from MDR? Indeed, they are the previous-gen utility service before an MDR. They engage in broad threat monitoring purposes and help send qualified alerts to the security team. The service also aids in compliance and vulnerability management. However, while considering the active response to threats, MSSPs fall back often. Usually, incident response activities should get performed from the client’s end. But many of the in-house analysts fall short of the needed expertise. Therefore, the enterprise must look for extra service partnering. On the contrary, MDR delivers both mitigation and remediation with minimal investment.

Finally, we are with security information and event management (SIEM). The process involves fetching data from various network sources/ devices, and thereby catching anomalies that mark suspicious. Other capabilities include technology solutions, managed event processing and alerting services. But one challenge that comes from the client-side is the constant difficulties in understanding results generated by the process. Like an MSSP, clients lack the in-house professionalism to fully-utilize SIEM solutions. A quick time to value and comparatively less price gives MDR an edge over MSSP solutions.

Selecting the right MDR Service Provider

One vital thing as a customer you will require is to have the right managed security services consultancy to partner your need. MDR security services have many service categories. Knowing the partnering agency’s core capabilities and domain of expertise is keen. By doing this, you can affordably pack your solution as per the available security investment and requirements. Let’s dive into five major requirements to look at while selecting MDR Service Provider.

  • Ensure that your service vendor has good knowledge of the latest threats, have new skills, and has a higher competence.
  • Check if your MDR service has access to the required data and resources at the time of need.
  • Check how qualified your MDR team stay on hunting new-gen threat vectors.
  • Know how your MDR service provider effectively communicates with your team.
  • Know how flexible the service model is, whether it offers a 24/7 offering.

Final Thoughts

MDR- The new facet of information managed security services is proving beneficial for organizations looking for a robust and comprehensive security posture. While searching for better incident response and mitigation, partnering with an MDR vendor could be a cost-effective solution. Managed endpoint threat detection and response, proactive uncovering of threat vectors, in-depth investigation and higher resource efficiency makes MDR service a popular service model in the present digital tick.
