What is Managed Detection and Response (MDR)?

Managed Detection and Response, or MDR, is a type of cybersecurity service that combines human expertise and technology to find and limit the impact of cyber threats quickly. It can be done by performing threat hunting, monitoring, and responding. The prime advantage of MDR is that it rapidly helps decrease threats’ impact without the need for an additional workforce.

Managed Detection and Response (MDR) Service Features:

MDR falls under the Security as a service offering category, where an enterprise outsources some of its security operations to a third-party provider. As the name implies, it detects threats and remediates them within an organization’s network.

MDR security service provides different features such as:

Detailed investigation of Incident:

MDR security service providers investigate an alert and determine whether it is an actual incident. This can be done with data analytics, human investigation, and machine learning.

Alert Triage:

Security incidents vary in importance and are influenced by multiple factors. An MDR provider prioritizes security events, ensuring the most critical ones are addressed first.

Remediation:

A Managed Detection and Response (MDR) provider offers incident remediation as a service, meaning they will remotely respond to a security event within a customer’s network.

Proactive Threat Hunting:

An organization’s security measures might only catch some incidents. Managed Detection and Response (MDR) providers actively search the network and systems for signs of an ongoing attack and, if found, take steps to address it.

What Challenges Does (Managed Detection and Response) MDR Solve?

Sophisticated Threats:

As cyber-attacks evolve, their tactics and procedures (TTPs) require continuous monitoring, active hunting, and quick response to stop them before they cause harm.

Less resources:

Enterprises need more resources to fight against sophisticated cyber threats by threat actors or adversaries.  

Addressing Alert Fatigue:

Security teams are inundated with numerous low-quality alerts, leaving them with insufficient time for threat hunting.

MDR Benefits

Companies using Managed Detection and Response (MDR) can quickly reduce their time to detect and respond to cyber threats from days to minutes, quickly reducing the impact. This is one of many benefits an organization can take from MDR. Some of them are mentioned below:

• Enhance security posture and increase resilience to potential attacks by fine-tuning security configurations and removing unauthorized systems.
• Detect and neutralize covert, advanced threats with ongoing managed threat hunting.
• Enhance threat response and restore endpoints to a secure state with guided actions and managed remediation.
• Shift staff focus from routine incident response tasks to more strategic initiatives.

How does MDR work?

Managed Detection and Response (MDR) services help monitor, identify, and address organizational threats. They use an Endpoint Detection and Response (EDR) tool to ensure visibility into security events on endpoints.

Relevant threat intelligence, advanced analytics, and forensic information are provided to human analysts. These analysts prioritize alerts and decide on the best response to minimize the impact and risk of incidents. Ultimately, by combining human and machine efforts, the threat is neutralized, and the affected endpoint is returned to its original state before the infection state.

Some of the core capabilities of an MDR includes:

Prioritization:

Managed prioritization aids organizations struggling with the sheer number of daily alerts by helping them decide which ones to address first. Known as “managed EDR,” this process uses automated rules and human review to differentiate between harmless events, false positives, and actual threats. The outcomes are enhanced with additional context and refined into high-quality alerts.

Threat Hunting:

Every threat originates from a human strategizing how to evade their target’s defenses. While machines are intelligent, they lack the cunning only humans can provide. Skilled and experienced human threat hunters are essential for detecting and alerting the most elusive and covert threats that automated systems might overlook.

Investigation:

Managed investigation services accelerate threat comprehension by adding context to security alerts. This enables organizations to understand what occurred, when it occurred, who was impacted, and the extent of the attack. With this information, they can devise an effective response plan.

Guided Response:

Guided response provides actionable guidance on effectively containing and addressing specific threats. Organizations receive advice on fundamental activities, such as isolating a system from the network, and advanced procedures, like step-by-step instructions for eliminating threats and recovering from attacks.

Remediation:

The final stage of incident management is recovery. Proper execution of this step is crucial to ensuring the organization’s investment in endpoint protection is well-spent. Managed remediation restores systems to their pre-attack condition by removing malware, cleaning the registry, ejecting intruders, and eliminating persistence mechanisms. This process guarantees the network returns to a secure state, preventing further compromises.

MDR v/s MSSP

The difference between MSSP (managed security services provider) and MDR (managed detection and response) becomes more evident when considering their full names rather than their acronyms. An MSSP primarily offers security services as a vendor, whereas MDR specifically encompasses threat detection and response.

While an MSSP typically includes MDR among its services, not all MSSPs necessarily provide MDR.
