Gartner defines insider risk management as a methodology that includes the tools and capabilities to measure, detect and contain undesirable behavior of trusted accounts in the organization. It includes solutions that monitor the behavior of employees, service partners and key suppliers working inside the organization. These tools then evaluate whether behavior falls within the expectations of the role and corporate risk tolerance. For CISOs and cybersecurity leaders, insider risk management refers to the use of technical solutions to solve a fundamentally human problem. Managing insider risks requires collaboration among many cross-functional partners. Components of an insider risk management methodology are policies, guidelines and investigative work that fall outside the bounds of a typical cybersecurity organization. For our purposes, the insider risk management market consists of tools and solutions that monitor the behavior of employees, service partners and key suppliers working inside the organization. It evaluates whether behavior falls within the expectations of the role and corporate risk tolerance.
Network detection and response (NDR) products detect abnormal system behaviors by applying behavioral analytics to network traffic data. They continuously analyze raw network packets or traffic metadata within internal networks (east-west) and between internal and external networks (north-south). NDR products include automated responses, such as host containment or traffic blocking, directly or through integration with other cybersecurity tools. NDR can be delivered as a combination of hardware and software appliances for sensors, some with IaaS support. Management and orchestration consoles can be software or SaaS.
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
