Chapter 4. Security

WMI-based administration scripts operating over a remote connection send data over the network in clear
text by default. You can enhance security by modifying WMI-based administration scripts to establish an
encrypted remote connection as follows:
1. Set an impersonation level of "impersonate"
2. Set an authentication level of "pktPrivacy"
See Appendix A "Sample Visual Basic scripts for configuring BIOS settings" on page 17 for sample scripts
used to implement WMI-based administration scripts that include these parameters for encryption.
