Managed Detection and Response (MDR): A Complete Guide to Proactive Cybersecurity

The world of cyber attacks is evolving at an ever-increasing pace, posing new challenges to business owners of any size.

Attacks on companies can range from ransomware to unauthorized access or even data breaches, and the need is evident to protect your company's network from potential attacks which may hinder the business's activities.

MDR is a security approach which is aimed at helping the organization detect, investigate and manage different security incidents.

It includes using advanced security technologies and experienced security professionals who work to detect, prevent and react to potential threats that an organization faces.

For the companies which do not have the capacity to form an internal security team, MDR can be a solution to get professional assistance in the field of security.

Understanding how it works can help get some ideas about the advantages it brings and the effectiveness of this technology.

What Is Managed Detection and Response (MDR)?

Managed Detection and Response (MDR) is a cybersecurity service combining threat detection, real-time monitoring, security investigations, and incident response.

It is delivered by a third-party security provider that helps detect and address any security threats that exist in an organization’s IT infrastructure.

In contrast to cybersecurity products that generate alerts for security events, the use of MDR requires the involvement of security experts who will investigate suspicious activity, find out if it poses any danger, and initiate necessary response based on the terms of service agreement.

A managed detection and response solution can monitor various objects such as endpoints, servers, cloud environments, network communications, etc. The analysis of security events and investigations of suspicious activity help organizations see potential threats to their cybersecurity.

The primary aim is to lower the period between the detection and response to an incident.

Why is MDR Relevant to Contemporary Businesses?

Businesses become more dependent on cloud technology, remote access, software programs, and connected devices. Although all these technologies increase business efficiency, they also increase the attack surface.

Some issues require MDR as a solution:

• Growing cyberattacks: Hackers find new ways of bypassing security measures and exploiting any available vulnerabilities.

• Lack of security knowledge: Some businesses may not afford hiring a full team of security analysts due to small budgets.

• Large number of alerts: Security tools can produce a large amount of alerts.

• Delay in investigation: Ineffective investigation process can be caused by absence of proper protocols.

• Requirements: Some organizations need certain security controls, incident response and monitoring.

MDR will help to solve these problems by providing access to security experts, investigation of incidents and response. Therefore, organizations will be able to improve their security operations and free up time for other tasks.

How Managed Detection and Response Works?

Usually MDR operates within the cycle of continuous monitoring, investigation and response. How exactly these steps will be performed, will depend on the provider and the particularities of the service agreement.

1. Continuous Security Monitoring

Firstly, there is a need for continuous monitoring of the relevant systems as well as collection of security telemetry data from endpoints, servers, cloud services and security products. This will help in gaining visibility into the system activity and detecting any suspicious activity.

2. Threat Detection and Analysis

The threat detection tool analyzes the incident and identifies any suspicious pattern which produces an alert. The security analyst analyzes the alert, determines its severity, gathers all the data and decides whether it is really a threat or just the system’s routine operation.

3. Threat Investigation

In case of any suspicious activity requiring additional analysis, security analysts conduct an investigation of systems, user accounts, processes, and events. As a result, they find out what actually took place, what assets were affected, and whether the attacker succeeded in gaining access to the system.

4. Incident Response and Containment

When a threat has been detected, MDR provider performs actions according to the previously agreed upon response procedure.

The actions may differ depending on the service and include, for example, isolation of the endpoint, disabling of the compromised account, blocking of malicious behavior, or cooperation with the company's IT staff to solve the problem.

Response to the threats should be planned in advance.

5. Guidance and Reporting for Recovery

Following containment, the vendor can assist in root cause analysis, recommendations for action to improve, and recovery processes.

Information within the incident report could include details about the incident itself, any actions that were taken to resolve the incident, and other information useful to improving security controls.

The above cycle provides an insight into the ongoing process of detecting and responding to cybersecurity incidents.

Benefits of Managed Detection and Response (MDR)

Faster Threat Detection and Response Time

Prompt detection enables the company to reduce the time during which the hackers will have access to the information, move around the network, and create a disruption to business. MDR uses both technology and analysts to identify and investigate the incident.

The actual detection and response time depend on the service-level agreement of the provider and the level of severity of the incident.

Access to Cybersecurity Professionals

Hiring and keeping cybersecurity experts is difficult. With MDR services, organizations have access to specific analysts and incident response tools, but not necessarily need to have a full-scale security operations center inside the company.

Improved Threat Visibility

Security events may come from various systems and applications. The MDR provider can correlate the data and find out the patterns that may not be evident in individual alerts review.

Decreased Strain on Internal IT Departments

Internal IT departments have not only security responsibilities, but they also operate the infrastructure, support users, do maintenance, develop business applications, etc. MDR allows decreasing the load on internal departments with security investigation and focus on other activities.

Business Continuity Support

Events in cybersecurity can lead to disruptions, financial losses, downtime, etc. The process of detection and response helps an organization to get prepared for events and their impact.

Flexible Security Capabilities

MDR services may prove beneficial to businesses at any stage of their security maturity. Organizations may choose the desired services based on their infrastructure, risk profile, internal capabilities, and required level of support.
