Implementing Default Protection

You can effect full default protection for specific pre-defined resources in the Resource Descriptor Table (RDT) Record by attaching the DEFPROT attribute to the particular resource using the TSS REPLACE(RDT) command function.

For example:

TSS REPL(RDT) RESCLASS(VMMDISK) ATTR(DEFPROT)

This TSS command function secures default protection for all minidisks, and provides flexibility in choosing the resources (minidisks, diagnose instructions, CPUs, etc.) that you want to protect.

You may regret giving every resource full default protection because you may find there are many resources in your organization that do not require protection.

Note: You can also dynamically define new resource classes to the Resource Descriptor Table, and, in turn, give them default protection. For more details, see the Command Functions guide.
