Cyber asset attack surface management (CAASM) is focused on enabling security teams to overcome asset visibility and exposure challenges. It enables organizations to see all assets (internal and external), primarily through API integrations with existing tools, query consolidated data, identify the scope of vulnerabilities and gaps in security controls. These tools then continuously monitor and analyze detected vulnerabilities to drill down the most critical threats to the business and prioritize necessary remediation and mitigation actions for improved cyber security.
Security information and event management (SIEM) is a configurable system of record that collects, aggregates and analyzes security event data from on-premises and cloud environments. SIEM processes security event data for the purposes of threat detection, investigation and response. It natively supports data normalization and offers user-configurable detection content and reporting to orchestrate threat mitigation and satisfy compliance requirements. These solutions are delivered via a SaaS platform or client-hosted on-premises or private cloud. 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. Designing and executing near real-time monitoring and alerting content. 3. Enriching and investigating security events of interest. 4. Supporting manual and automated response actions. 5. Maintaining and reporting on current and historical event data.
