Our system has stringent requirements for database passwords. One of the many rules is that old passwords cannot be reused for a very long time. This includes both a long number of days, and a large number of different passwords in between reuses. Developers and testers frequently have a lot of different accounts to conduct testing. The password policy makes it difficult to keep track of all the different passwords that have to keep changing.
Recently a tester asked a DBA to reset her passwords back to the ones she normally uses. The DBA attempted to do this, but was halted by the implementation of the security standards. It was too soon to reuse the old password. So the DBA chose a new password for the tester. Later I spoke with the DBA about this problem. Both he and I knew that it was the database profile that tied the user to the password verify function which prevented quick password reuse. I said we could just temporarily switch the user to a different database profile. Then the password rules would not be enforced. Oracle would not recheck the password when the original database profile was restored. This seemed like the ultimate plan to skirt the database password rules. In fact I coded up a script to do this for all my database accounts.
The DBA I spoke with knew about the profile swap trick. But he was hesitant to do this for the testers. He likes to do things by the book. The trick would be violating the security policy. I told him he was right. However we are just talking about a test environment. In reality, it is impossible to keep track of all the changing password for the multitude of accounts that we require. So people write down their passwords. The security rules get violated anyway. But at least the system was set up to discourage illegal password reuse.
I think the DBA has the right attitude. If you are always serious about security, you will most likely be safe always as well. It is a slippery slope to skirt security rules sometimes. There are times when the urgency of the moment requires some rules to be bent. But this decision should not be taken lightly. However I have not thrown out my script which resets my passwords by first switching up the profiles. In that way I am able to remember all my well known passwords and not write them down. That is my compromise.
