What are the four data expiration values defined in the system?

The correct answer identifies four different categories for data expiration values that are crucial for managing data within the Tenable Security Center.

"Data" refers to the core information that is collected during scans and assessments. It is vital to determine how long this data should remain available for review and reporting.

"Mitigated" describes data that has been addressed or resolved, indicating that the vulnerabilities have been remediated or mitigated, and may therefore have different retention requirements compared to raw data.

"Active Scan" pertains to ongoing scans that are currently relevant. This category ensures that data from active scans is kept readily accessible for immediate analysis and response to security threats.

"Global" indicates settings or policies that are applied universally across the entire system. Having a global perspective on data expiration helps maintain consistency and compliance across various projects and user accounts.

These values help organizations effectively manage their security data lifecycle, balancing the needs for historical analysis with storage and performance considerations. The other choices do not fully represent the framework needed for effective data expiration management in the context of Tenable Security Center.
