Following is the list of pre-defined factors
SQL> SELECT OBJECT_NAME, OBJECT_TYPE FROM DBA_OBJECTS WHERE OWNER=’DVF’ AND OBJECT_NAME LIKE ‘F$%’
17 rows selected.
We can also create a new factor, which will internally create a function F$. We’ll make use of pre-defined MACHINE factor, in the example.

We want to force this restriction on all users connecting to the database. So in the command rules section, create a command rule CONNECT & assign the rule set.
Now to test the rule by logging from the different host mentioned in the FACTOR expression.
