    Study Notes

    SYSADM Functions and Access

    • SYSADM performs functions related to instance (DBM) configuration
    • SECADM can grant SYSADM access to:
      • Create and manage database objects
      • Control database access and authorization
      • Perform database maintenance and backup/restore operations
      • Modify database configuration parameters

    SYSADM Access Limitations

    • SYSADM access does not imply authority over:
      • Security administration tasks
      • Granting privileges to other users

    Privileges in DB2

    • Explicit Privileges: Specifically granted to a user or role for a particular object or action
    • Implicit Privileges: Implied by a user's role or group membership, without explicit granting

    Trusted Context in DB2

    • A Trusted Context is created for a three-tier application system to:
      • Allow middle-tier applications to access databases on behalf of clients
      • Enable secure and efficient authentication and authorization

    Authentication in DB2

    • Authentication involves verifying the identity of a user or application
    • In DB2, authentication is used to ensure that only authorized entities access the database

    DB2 Security Combination

    • DB2 uses a combination of:
      • Authentication: Verifying user identity
      • Authorization: Controlling access to database objects and actions

    SECADM Tasks

    • SECADM (Security Administrator) performs tasks related to:
      • Managing user access and privileges
      • Defining security policies and roles
      • Granting and revoking access to database objects
