Partition security

System administrators can install a server with the Evaluation Assurance Level 4+ (EAL4+) option during a base operating system (BOS) installation. If you select this option, there are restrictions on the software that is installed during BOS installation and network access restrictions.

Starting with AIX 5L Version 5.2 with the 5200-01 Recommended Maintenance package, the EAL4+ technology runs on POWER4 processor hardware platforms that support logical partition configuration. The following peripherals are supported on EAL4+ servers:

• Storage devices
  • Terminals
  • Printers
  • Hard disks
  • CD-ROM drives
• Backup devices
  • Streamers
  • Floppy disk drives
• Network devices
  • Ethernet
  • Token ring
