Managed Detection and Response (MDR) has become a critical aspect of cybersecurity for businesses of all sizes. As cyber threats evolve and become more sophisticated, organisations realise the importance of a comprehensive security strategy that includes advanced threat detection, incident response, and remediation capabilities. In this article, we will focus on what Managed Detection and Response (MDR) services are, how they work, and the benefits they offer to businesses of all sizes.

Let’s get started!

What Is Managed Detection and Response (MDR)?

MDR is a SAAS (Security As a Service) that combines advanced threat detection technologies and services, such as SIEM (Security Information and Event Management) and EDR (Endpoint Detection and Response), with a team of skilled security analysts who monitor and respond to advanced threats in real-time.

Unlike traditional approaches to cybersecurity that rely solely on security tools like firewalls and antivirus software, MDR services take a proactive approach to threat detection and response. By constantly monitoring an organisation’s environment, MDR providers can detect and respond to threats before they cause serious damage.

MDR uses EDR because EDR systems often promote the ability to develop and deploy customised detection and response rule sets to complement default “out-of-the-box” features. EDR technology also provides rich contextual information about potential threats, such as the device’s location, user identity, and the specific actions the attacker takes. This information enables MDR providers to assess the severity of a cybersecurity threat and respond appropriately and quickly.

Managed Detection and Response services typically include 24/7 monitoring, threat hunting, incident response service, and forensic investigation capabilities. These services are designed to detect and respond to various threats, including malware, ransomware, phishing attacks, insider threats, and advanced persistent threats (APTs).

MDR services are often provided by third-party cybersecurity vendors with the expertise and resources to offer their clients robust protection. These vendors typically work with companies of all sizes, from small startups to big firms across various industries.

How Do Managed Detection and Response (MDR) Services Work?

MDR services typically combine advanced threat detection technologies with human expertise and analysis. The process typically includes the following steps:

1. Prioritisation

Managed prioritisation assists firms that struggle daily to choose which of their enormous volume of warnings to answer first. Managed prioritisation, or “managed EDR,” uses automated criteria and human inspection to separate genuine risks from innocuous events and false positives. The outcomes are enhanced with added information before being condensed into effective alerts.

2. Data Collection and Analysis

The MDR service provider collects data from various sources, including network devices, endpoints, cloud services, and applications. This data is then analysed using advanced threat detection technologies, such as SIEM and EDR, to identify potential threats.

3. Threat Detection and Analysis

Once a potential threat is detected, the MDR service provider’s security team analyses the data to determine the severity of the threat and its potential impact on the client’s network. The security teams may also conduct additional threat-hunting activities to identify other threats that may have gone undetected.

4. Incident Response

If a threat is confirmed, the MDR service provider’s security team will initiate an incident response plan to mitigate the threat and prevent further damage. It may include isolating affected systems, blocking network traffic, and removing malicious code. The security teams will also work to identify the incident’s root cause and take steps to prevent similar attacks from occurring in the future.

5. Forensic Investigation

Following the incident response, the MDR service provider’s security team will conduct a forensic investigation to identify the cause of the incident and gather evidence for legal or compliance purposes.

6. Remediation

Recovery follows an occurrence as the last phase. The organisation’s entire investment in its endpoint security program will be lost if this step is not carried out correctly. Managed remediation eliminates malware, cleans the registry, and kicks out attackers to return computers to their pre-attack condition. The network is restored to a known good condition, and additional compromise is avoided thanks to managed remediation.

Benefits of Managed Detection and Response (MDR) Services

MDR services offer a wide range of benefits to businesses of all sizes, including:

1. Comprehensive Threat Detection and Response

MDR services provide a comprehensive approach to threat detection and response, leveraging advanced technologies and skilled security analysts to monitor and protect networks against cybersecurity threats. This can help businesses to detect and respond to threats quickly, minimising the potential impact of an attack by strengthening an organisation’s security posture.

2. 24/7 Monitoring and Support

MDR services typically operate around the clock, providing 24/7 monitoring and support to ensure that businesses are always protected. It can be particularly expensive for businesses to maintain their in-house security team.

3. Reduced Risk and Increased Compliance

MDR services can help businesses to reduce their overall risk of cyber attacks, protecting their networks, data, and reputation. They can also help businesses to comply with regulatory requirements, such as HIPAA, PCI-DSS, and GDPR, by implementing security controls and providing regular reporting and audit trails.

4. Access to Skilled Security Professionals

MDR services provide businesses access to skilled security experts with experience detecting and responding to cyber threats. This can be particularly valuable for businesses needing more resources to hire their in-house security team or additional expertise to supplement their existing one.

5. Cost Savings

MDR services can be more cost-effective than maintaining an in-house security team, particularly for small and mid-sized businesses. By outsourcing their security needs to an MDR provider, businesses can avoid the cost of hiring and training their security personnel and purchasing and maintaining their security technology.

6. Scalability

MDR services can be scaled up or down as needed, depending on the changing needs of a business. This flexibility can be particularly valuable for businesses experiencing rapid growth or requiring additional security staff during peak periods.

SIEM as a Managed Detection and Response (MDR) Component

Security Information and Event Management (SIEM) is a technology solution used to collect, store, analyse, and report security-related data from various sources within an organisation’s network.

SIEM tools help to detect and respond to security incidents in real-time by monitoring and analysing security events and logs generated by network devices, servers, applications, and other security technologies. These events are collected in a central repository, which analyses them for signs of suspicious or malicious activity.

Managed Security Service Providers

MSSPs are third-party companies that provide managed cybersecurity services to organisations. These services can include threat detection and response, vulnerability management, compliance reporting, and security operations centre (SOC) management. Managed security services provider uses advanced technology, expert analysts, and 24/7 monitoring and support to help organisations detect and respond to security threats.

What Is the Difference Between MDR & MSSP?

1. Scope of Services

MSSPs typically offer various security services, such as firewall management, intrusion detection and prevention, vulnerability assessments, and more. MDR, on the other hand, is focused on detecting and responding to security threats. MDR providers typically use advanced analytics and threat-hunting techniques to identify and respond to threats in real time.

2. Response Time

MDR services are designed to respond quickly to security incidents, often within minutes or hours. MSSPs may be less focused on incident response and have longer response times.

3. Skillset

MDR providers often specialise in incident response and threat hunting. MSSPs, on the other hand, may have a broader range of security expertise.

4. Level of Customisation

MSSPs may offer a range of security services that one can customise to meet an organisation’s specific needs. MDR providers, however, often provide a more standardised set of services with less room for customisation.
