Basically security as it applies to the questions you ask addresses that warm and fuzzy feeling you have of knowing that if something goes wrong you have done the easiest things you can do ensure recovery.

To answer your questions:

  1. Users who have system table space as default and have been granted privileges to create database objects, especially tables and views, may inadvertenlty USE UP all available resources that the system may require - not a good thing. Your database will quit functioning due to various errors depending on how/which resource is used up.
  2. If archive logging is not turned on you risk the possibility of not being able to recover CRITICAL data in event of a database crash or corruption. You need to know where the archive logs are being saved and ensure that only trusted individuals such as your DBA have privileges to these files to ensure they are not inadvertently deleted/truncated/corrupted thus rendering recovery of CRITICAL data impossible.
  3. Multiple redo logs ensure data integrity and greatly increase the possibility of recovery if disk failure occurs. That is, if disk A and B store redo logs and the database goes down due to a disk crash and suppose disk A crashes as well, disk B redo logs can be used to recover the database to the point in time the crash occurred.

The question you have to ask - "Do I want to be responsible for losing CRITICAL DATA due to poor security measures at the lowest level?"
