Your reference sounds like a large corporation but what about medium and small corporations and small businesses, mom and pop and the like. You don't have the same corporate infrastructure capacity, man power or time to apply this procedure. Also, I think we're getting away from my original question(s).
1. You answered that one. I have found that a lot of IS/IT Managers/Directors have security rights to their general user account, their password is set to never expire and it's usually about 6 characters or less, like bob001 for January. In very small businesses I find that EVERYONE has administrative rights.
2. Should anyone have admin rights assigned to their general user account or should only administrative accounts be provided to modify security settings?
Let me say that I DO NOT favor having one catch all administrative account. I believe each person that has a need to perform duties with administrative rights should have a separate administrative account apart from their general user account.
I also do not think anyone not qualified to work at certain levels of security should ever have access, this includes any/all forms of management, especially the IT manager. It is a security risk.
I don't work on major parts of my car because I do not want an inexperienced mechanic working on my car.
I disagree that an technically unqualified IT Manager should have any access to any area of the network they are not qualified to work on. The network doesn't belong to them. It belongs to the company. Managers are not hired to support the system. They are hired to manage the people that are qualified to support the system.
I made a mistake and informed my boss once on how to run a vrepair on a Netware volume that had name space support. He called me up early one morning and told me he removed the name space support like I showed him when he ran vrepair and now the system has issues. "Now what do I do?"
He also told me he has a system partition. The server was a Compaq and if you're familiar with Compaq, you'll know what a system partition is. Putting the SmartStart CD into the drive, which DID NOT have a system partition initiated SmartStart to create a 5Mb DOS partition and to start unpacking files to create a system partition. This just wiped out the DOS partition that was already there. It also messed up the location of all of the other partitions and even created a 1 byte partition. He then said he wasn't sure there was a backup in the last 45 days. He also said it was end of year and finance had auditors in and they were 3 days away from finishing. Everything could have been lost. Thirty-six hours later, after all attempts had failed and with no other drives available to try a restore, prior to risking restoring to the production server, I asked for a CD of Norton Utilities and was able to repair the partition table. All that was lost was the original DOS partition and we had the license and drivers backed up on floppy. The Netware partition showed the ending sector at the start of the partition and the starting sector at the end. The Netware partition would never load until that was rectified. We skated by on that one and it is one of the reasons I asked this question but it was not the worst thing he ever did to the network.
I see security risks like these everyday and it answers a lot of questions of why people get compromised by a worm that exploits a vulnerability that had a patch available months or even years earlier. The biggest issue I have with this is that these people still have their jobs.
