Introduction to Windows IPSec

keys are easy to implement, but improper use can have a negative impact. Microsoft recommends that you do not use preshared key authentication in Active Directory because the key value is not securely stored and is therefore difficult to keep secret. Pre-shared key values are stored in plaintext in the IPsec policy. Any member of the local Administrators group can view the local IPSec policy, and any syste

Protecting Wireless LAN security-protecting users

Authentication The first step is to establish a user identity to control access to network resources. Some enterprises authenticate users by verifying the media access control MAC address. However, for intruders, it is easy to copy MAC addresses from valid frames and then change the MAC addresses on the intruders laptop to valid MAC addresses. In addition, identity-based authentication can often use the IEEE 802.1X Standard and the extended Identity Authentication Protocol EAP) and remote user d
