How Does MDR Work?

Managed Detection and Response (MDR) is used by companies to look for and respond to potential compromise in an environment. There is no single element that forms MDR; it is a combination of cyber security policies and practice that, when used effectively, mitigates the effect of cyber-attacks. 

In this blog, we look at how MDR works, and why it can benefit all organisations, regardless of their size. 

What is Managed Detection and Response (MDR)? 

Managed Detection & Response is a service facilitated by a SOC that monitors a specific environment for indicators of compromise (IOCs). An environment is monitored using a combination of technology and human intelligence, and the work is both proactive and reactive. Threat hunting is done by cyber security professionals to identify threats before they become problematic.  

In this blog, we look at how MDR works, and why it can benefit all organisations, regardless of their size. 

The scope of MDR covers everything from identifying issues to isolating and remediating them. A managed detection and response service therefore provides an end-to-end service. To deliver an effective MDR service, an MDR provider can combine the following technologies: 

Next Generation Anti-Virus (NGAV) 

NGAV goes beyond traditional antivirus systems by using advanced techniques such as machine learning and behavioral analysis to block more sophisticated threats. NGAV tools are designed to identify unknown threats and zero-day exploits that traditional antivirus systems might miss, providing an additional layer of protection. 

Endpoint Detection and Response (EDR) 

EDR tools monitor and analyse endpoint activity to detect suspicious behavior. EDR systems do the following: 

• Collate data from endpoints; 

• Analyse data for indicators of compromise; 

• Offer detailed insight into the nature and extent of potential threats; 

• Facilitates quick detection and therefore minimises response time to attacks, mitigating the risk of potential damage. 

Security Information and Event Management (SIEM) 

SIEM systems aggregate data from multiple sources across a business’ IT infrastructure. By correlating events and finding patterns, SIEM solutions help to detect anomalies and threats from devices such as firewalls, email gateways and other non-user device event sources. They provide a central view of a security landscape, making it easier to manage and respond to incidents as they arise. 

Extended Detection and Response (XDR) 

XDR integrates various security products into a cohesive system, providing a broader view of the threat landscape. By making links between data across endpoints, networks, and cloud environments, XDR enhances the ability to detect and respond to complex and evolving threats. This holistic approach improves the efficiency and efficacy of threat detection and response efforts. 

In contrast to SIEM, XDR is designed to bridge the gap between EDR and a full fledged SIEM solution, and provides additional key data sources to existing EDR data without the time and effort investment involved in managing a SIEM. 

Using these technologies, a security operations center (SOC) has complete visibility of an organisation’s security status. Analysts can use this data and visibility to proactively assess the business’ current level of exposure and monitor data as it updates to spot problems early on. 

By combining a comprehensive suite of technologies with human-driven services, the value of MDR becomes clear; it avoids the problems and pitfalls that come with keeping these technologies and services in silos. With a dedicated team providing MDR services, you have a full-stack service that gives comprehensive coverage. 

The Purpose of MDR 

MDR gives companies the assurance that someone is always watching and ready to respond. It provides constant coverage, and this reduces the time to remediation of any issues. 

How does MDR work? 

Managed Detection and Response works by combining reactive and proactive security technologies and methodologies to protect an environment as effectively as possible. It employs monitoring, threat hunting, and incident response to provide a comprehensive security service. 

A specific example of an incident handled by MDR services might be as follows: 

• During some routine threat hunting, a SOC analyst reviews data from an EDR tool which seems unusual. 

• This data is cross referenced with behavioural patterns from a specific device. Logs from company platforms are analysed to review activity. 

• Upon review, the device’s activity is classed as suspicious. The client is informed. 

• The offending device is quarantined to restrict its access to other environments in the client’s IT infrastructure. This mitigates further risk. 

• The client receives a thorough assessment and explanation of the situation so that they can make appropriate decisions on their side. This includes what could have been compromised, the effect it could or has had, and the steps taken to mitigate the risk. 

In this example, a threat has been identified via proactive security methods, and the response has resulted in successful mitigation of risk. ganisation’s security posture. Ensure your employees know how to spot a fake email with cyber security training.  

The Benefits of MDR 

Managed Detection and Response provides the key benefit of saving the client time, money, and heavily reduces the risk of successful compromise, leading to financial loss or penalties, losing reputation or worst case or losing sensitive data.. 

Having internal resources to provide 24/7 can be very expensive, and that goes doubles given the expertise and experience that the resources would need to have. Additionally, the time and cost required to provide effective CPD for internal resourcing has a significant impact on the efficacy of a service which should, ideally, operate 24/7, 365 days per year. It is, therefore, necessary to review alternatives. 

Using an MDR service (such as that provided by CloudTech24) places those issues in the provider’s hands. A Managed Detection and Response vendor will be able to give cyber security coverage, delivered by highly trained personnel with refined expertise at a fraction of the operational cost of employing an internal resource.
