Which security principle involves monitoring, alerting, and auditing actions in real time?

The principle that involves monitoring, alerting, and auditing actions in real time is traceability. Traceability is crucial for maintaining a secure environment in AWS and refers to the ability to track and monitor activities across your cloud resources. This principle ensures that all actions taken within the system can be logged and reviewed, allowing for real-time alerts in the case of unauthorized access or suspicious behavior. By enabling traceability, organizations can better respond to security incidents, maintain compliance with regulatory requirements, and conduct thorough audits of their systems.

Regular updates focus on keeping software and systems current to protect against vulnerabilities. Data encryption involves securing information by converting it into a coded format that can only be read by authorized parties. Access control ensures that only authorized users have permission to access certain resources or perform specific actions. While these principles are important for a secure environment, they do not encompass the comprehensive monitoring, alerting, and auditing aspects that are integral to traceability.
