Replacing WEP with IPsec on OpenBSD, Windows XP

Contributed by jose on from the improving-wireless dept.

BSDForums.org writes: "WEP has been proven insecure and is thus inadequate for protecting a wireless network from eavesdropping or abuse. IPsec can be used as a replacement to WEP in the following scenarios . Joshua Stein has implemented IPsec on OpenBSD with manual keying between a router and a client as a replacement. Also, Thomas Walpuski describes in detail the configuration of an IPsec Host-to-Host connection between OpenBSD and Windows XP Professional with Authentication via X.509v3 Certificates." Thanks for the notes, these will come in handy!

    There have been quite numerous articles about using IPSec to replace WEP for providing secure communications in a wireless network. However, the industry is working on solutions based on the 802.1x spec.

    Has anyone field-tested such solutions and their security? Would one still need IPSec in this context?

    We have put up a paper in german for quite a while now on www.openbsd.de/kochbuch.php.

    It will implement x509v3 certauth for all sorts of clients ( linux, macos, windows, openbsd )
    with examples and conf.files

    I've been doing this for a while. I wrote up a document on
    the subject. I'm connecting Linux FreeSWAN on a laptop to a wireless AP implemented on OBSD.
