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. © Copyright Lenovo 2008, 2012 15
