CHAPTER 28 System Security
28.2 What needs to be Secured?
You need to secure wherever your data is stored, transmitted, or accessed. This would include:
- Disks on the machine
- Tape backups
- Network connections
- Serial connections - modems, terminals, etc.
You should be concerned not just with loss or theft, or alteration of data, but also with loss of services.
If your machine has extremely sensitive data it shouldn't be on an outside network.
It may be that you'll need to isolate your site with a firewall. Should you need to do this check out the firewall books listed in Chapter 1.
