What is managed detection and response (MDR)? Managed detection and response (MDR) is an outsourced service that helps organizations detect threats on endpoints, respond to them and carry out proactive threat hunting.
MDR services typically include an endpoint detection and response (EDR) platform, which is deployed on company endpoints, and human security experts. MDR providers give their customers access to security analysts and engineers who can help with endpoint security, network security management, triage of alerts and responding to real security incidents (here’s some further reading and more background on managed detection and response platforms).
Why is MDR Important?
Traditional managed security services (MSS) offer basic monitoring and alerting that do not provide the context and guidance needed to identify, respond to and remediate real security incidents. It leaves organizations exposed to many threats that pass through these basic services.
How MDR Helps Protect Organizations
MDR provides a proactive, outcome-driven approach that goes beyond the scope of what MSS vendors can offer. Common MDR services include:
- Continuous network and endpoint monitoring.
- Security orchestration.
- Threat hunting.
- Integrated response actions like remote threat containment.
- Advanced MDR services also offer extended detection across clouds such as AWS, GCP, Azure and common SaaS suites like Google Workspace and Office 365. Other providers can protect incident command systems (ICS) and supervisory control and data acquisition (SCADA) systems within operational technology (OT) environments.
What is DevSecOps?
DevSecOps is a software development methodology that unifies previously disparate development (Dev), security (Sec), and operations (Ops) teams. It aims to integrate security across all development life cycle phases, including design, development, testing, deployment and delivery. It involves using automation to integrate security across all phases.
In the past, security tasks were performed at the end of the development pipeline by a separate security team. Next, the product was tested by a quality assurance (QA) team. This approach worked when developers released software updates only once or twice per year. However, once software development teams adopted Agile and DevOps pipelines to reduce the development time, security became a bottleneck.
How DevSecOps Improves Security
DevSecOps integrates security into Agile and DevOps pipelines. It ensures teams can address security issues during the early phases of the development cycle. As a result, teams can apply fixes when it is easier and faster to remediate before products are released to production.
DevSecOps makes security a responsibility shared by all teams, including Dev, Sec and Ops. It is no longer the sole responsibility of one team that creates a security silo. Instead, it enables teams to automate secure software delivery, prioritizing security without slowing down the software development cycle.
How Managed Detection and Response (MDR) Solutions Benefit DevSecOps
DevOps has revolutionized application development. However, due to the high velocity of modern development methods, they can introduce security gaps and flaws.
In addition to regular security breaches occurring across the DevOps pipeline, new and sophisticated attacks, most significantly supply chain attacks infect the development systems themselves or third-party software components. This results in mega-attacks that can compromise millions of devices before being detected.
How can MDR help?
MDR is a relatively new cybersecurity offering but is beginning to have a major impact on companies seeking better protection with lower operational overhead. There are many overalls between MDR and DevOps. To integrate cybersecurity into production and deployment pipelines, some organizations are turning to a DevSecOps approach and MDR can help.
DevSecOps makes cybersecurity an integral part of the entire DevOps life cycle. As more organizations implement DevSecOps, they can supplement the knowledge and security best practices of in-house teams with the security expertise provided by MDR services.
How MDR Keeps DevOps Ahead
MDR keeps DevOps teams ahead of the latest threats by keeping developers up-to-date on emerging threats and vulnerabilities and providing advanced tools for continuous security monitoring and response in their development and deployment pipelines. A key benefit of MDR is that it provides access to experts who can take action to prevent attacks, not just provide recommendations.
MDR becomes a supporting element that allows developers to write more secure code as well as better secure their DevOps environment. With the help of MDR technology and experts, it becomes easier to identify advanced threats that can bypass security controls before they impact the DevOps environment or the resulting software product.
Considerations for Selecting an MDR Solution
- There are several important considerations when choosing an MDR platform suitable for a DevOps environment:
- Understanding of attack surfaces common in a DevSecOps environment, and the ability to monitor and control the relevant environments.
- Measures are taken to eliminate false positives and prioritize alerts. DevOps teams operate at high velocity and do not have time to wade through irrelevant alerts.
- Automated triage and response at all stages of the development lifecycle. In earlier stages, this should take the form of actionable recommendations for developers, and in later stages, full incident response for production environments.
All of this is useful as you find the right way to shift your organization to a true DevSecOps process.
