This invention discloses a method, apparatus, device, and storage medium for dynamic
password management in operation and
maintenance management. The method includes obtaining multiple
password items, constructing a set of
password instances carrying attributes based on the multiple password items, abstracting and encapsulating the password instances to generate a set of encapsulated password instances, generating a
password management system model based on the functional attributes of the encapsulated password instances to manage the group update, password binding,
encryption protection, hierarchical audit, and real-
time synchronization relationships among the encapsulated password instances, and performing password update, eviction, compliance detection, and external credential synchronization operations based on the
password management system model and generating a compliance report. Because this invention achieves centralized and automated
password management through password instance encapsulation and password management modeling, it improves batch update efficiency and ensures the consistency of external credentials by utilizing group update and real-
time synchronization mechanisms, enhances
storage security and operational
traceability through
encryption protection and hierarchical audit relationships, reduces the risk of leakage, and meets compliance requirements.
