Gartner defines managed detection and response (MDR) services as those that provide customers with remotely delivered security operations center (SOC) functions. These functions allow organizations to perform rapid detection, analysis, investigation and response through threat disruption and containment. They offer a turnkey experience, using a predefined technology stack that commonly covers endpoints, networks, logs and cloud. Telemetry is analyzed within a provider’s platform using a range of techniques. The MDR provider’s analyst team then performs threat hunting and incident management to deliver recommended actions to their clients. MDR offers outcome-driven security incident management that is predicated on the detection, analysis and investigation of potentially impactful security events and the delivery of active threat disruption and containment actions to respond to and mitigate the impact of cyber breaches.
SIEM is a configurable security system of record that aggregates and analyzes security event data from on-premises and cloud environments. SIEM assists with response actions to mitigate issues that cause harm to the organization and satisfy compliance and reporting requirements. The security information and event management (SIEM) system must assist with: 1. Aggregating and normalizing data from various IT and operational technology (OT) environments 2. Identifying and investigating security events of interest 3. Supporting manual and automated response actions 4. Maintaining and reporting on current and historical security events
Security orchestration, automation and response (SOAR) solutions combine incident response, orchestration and automation, and threat intelligence (TI) management capabilities in a single platform. SOAR tools are also used to document and implement processes (aka playbooks, workflows and processes); support security incident management; and apply machine-based assistance to human security analysts and operators. SOAR solutions must provide: - Highly customizable workflow process management that enables repeatable automated tasks to be turned into playbooks that run in isolation or joined together into more sophisticated workflows. - The ability to store (locally or in a third-party system) incident management data to support SecOps investigations. - Manually instigated and automated triggers that augment human security analyst operators to carry out operational tasks consistently. - A mechanism to collate and better operationalize the use of threat intelligence. - Support for a broad range of existing security technologies that supports improved analyst efficiency and acts as an abstraction layer between the desired outcomes and the custom-made set of solutions in place in your environment.
