IBM RACF

 

Introduced in 1976, Resource Access Control Facility (RACF) is an IBM mainframe security software product that provides access control and auditing functionality for the z/OS and z/VM operating systems.(1) A competitor to CA Technology's ACF2 , the RACF software is a corporate product that allows customers to tailor their control over the securing of valuable data, and the administration of user access on the operating system, depending upon the customer's security goals. The concept behind RACF is to provide sensitive files with the least possible access privileges, and to allow unusual use of resources only with the approval of an administrator, and the owner of the resource.(2) To that end, RACF employs protection mechanisms called "logical access controls" to restrict user access to information appropriate for them. To determine the appropriate level of each user's access, authorized user information and their access privileges are stored in a profiles database, which the system queries to determine access privileges during a resource request.(3) RACF has undergone continual development from 1976 to the present, achieving the TCSEC C1 level of trust in 1984, C2 in 1985, and the B1 level of trust in 1990.(4)
