Which of the following is a valid rule type?

A correlation rule for identity matching is a valid rule type in the context of identity security and governance. This type of rule is employed to determine how identities should be correlated across disparate data sources within the SailPoint Identity Security Cloud. Correlation rules play a critical role in successfully matching identities, ensuring that the system can accurately identify whether two records represent the same user, which is essential for maintaining a cohesive and accurate identity profile.

These rules enhance identity management processes by enabling the system to understand complex identity data and relationships. This is particularly important in large organizations that may have multiple systems and data sources containing user identity information. By utilizing correlation rules, the SailPoint platform facilitates efficient identity reconciliation, leading to improved governance and security posture.

The other options, while they may relate to concepts in identity management and security, do not align with the standard rule types recognized within the SailPoint framework. For instance, authorization rules and access control rules are typically broader concepts that govern permissions and access policies in general rather than specific rule types within identity correlation processes. Similarly, a blacklist rule is more of a strategy or practice used in access management rather than a defined rule type used within the correlation context.
