DefinitionAccess management (アクセス管理) means deciding access rights (アクセス権), that is, who may use which information and functions and how far, and making sure use stays within those limits.
ExplanationAccess rights state which operations, such as reading, changing, or running, a given user may perform on given data or functions. Access management covers both deciding and granting these rights and access control (アクセス制御), which allows or refuses use according to them. Rights are reviewed whenever users are added, transferred, or removed, so that no unneeded rights are left behind.
AnalogyIt is like a hotel key card: even once you are confirmed as a guest, it opens only your room and the gym, not the staff-only areas.
Memory hook"Access" means getting in, so access management is about drawing the line on how far each person may go.
