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
