Summary

Now that you've completed this tutorial, you should have a fundamental understanding of the following topics:

Elements of a DB2 security plan: You should understand the structure of the entire DB2 environment, which includes client, servers, gateways, and hosts. You should also understand authentication, authorization, and privileges.

DB2 authentication types: You should know how to set authentication types using the db2 update dbm cfg using authentication type command on the server, and using the db2 catalog database command on the gateway and client.

DB2 authorities: You should understand the basics of the SYSADM, SYSCTRL, SYSMAINT, and SYSMON authorities, which are set in the DBM CFG file. You should also understand the basics of the DBADM, LOAD, and SECADM authorities, which are set using the GRANT command and revoked using the REVOKE command. Additionally, you should know what command each authority is allowed to run.

DB2 privileges: You should have an understanding of the different types of privileges and what they allow a user to do. Examples are CONTROL, INSERT, DELETE, CREATEIN, DROPIN, REFERENCES, and SELECT. You should also know how a privilege is obtained/revoked explicitly (GRANT/REVOKE commands), implicitly, or (for packages only) indirectly. In addition to this you should have a basic understanding of label-based access control, and how to define different types of policies based on this new security concept.
