What is the default expiry duration for vulnerability data in Tenable Security Center?

The correct answer is based on the default configuration settings of Tenable Security Center, which specifies that vulnerability data has a default expiry duration of 365 days. This one-year period allows organizations ample time to analyze and address vulnerabilities before they are automatically cleared from the system. Understanding this duration is crucial for maintaining a current and actionable vulnerability management program. Any adjustments to this duration may be made based on specific organizational policies or requirements, but the standard setting is intended to balance data retention and operational efficiency. The access period ensures that organizations have sufficient historical vulnerability data to track trends and assess the effectiveness of their remediation efforts over a meaningful time frame.
