RACF is the key component of SecureWay Security Server, IBM's package of security services for the OS/390 and z/OS operating systems. Core functions include user authentication, authorization to data sets and a wide variety of resources, and auditing capabilities. IBM has developed RACF continuously since its introduction on MVS in 1976--with increasing emphasis on extending RACF security services to client/server, distributed computing, and e-commerce environments. RACF now offers support for authentication using digital certificates, for Kerberos V5 authentication via the Security Server Network Authentication and Privacy Service, and for directory services through the Security Server LDAP Server. But RACF faces stiff competition from other e-commerce security solutions. Has IBM's emphasis on supporting e-commerce undermined RACF's key strengths?
