A detective control is a type of internal control that seeks to uncover problems in a company’s processes once they have occurred1. Examples of detective controls include physical inventory checks, reviews of account reports and reconciliations, as well as assessments of current controls1. Detective controls use platform telemetry to detect misconfigurations, vulnerabilities, and potentially malicious activity in the cloud environment2.
In a Software as a Service (SaaS) service provider, privileged access monitoring is a detective control that can help identify unauthorized or suspicious activities by users who have elevated permissions to access or modify cloud resources, data, or configurations. Privileged access monitoring can involve logging, auditing, alerting, and reporting on the actions performed by privileged users3. This can help detect security incidents, compliance violations, or operational errors in a timely manner and enable appropriate responses.
Data encryption, incident management, and network segmentation are examples of preventive controls, which are designed to prevent problems from occurring in the first place. Data encryption protects the confidentiality and integrity of data by transforming it into an unreadable format that can only be decrypted with a valid key1. Incident management is a process that aims to restore normal service operations as quickly as possible after a disruption or an adverse event4. Network segmentation divides a network into smaller subnetworks that have different access levels and security policies, reducing the attack surface and limiting the impact of a breach1.
