Document Summary

Itm301 week 11: ras: remote access server is a server located normally in dmz and is responsible for user authentication. Ras is an old technology, designed for modem (isdn) access. Ras deploys a 2-way authentication called mschap v2. Mschap stands for microsoft challenge handshake authentication. Ipsec comes in 2 flavours: l2tp (layer 2 tunnel protocol) that offers 256 bit encryption called aes (advanced encryption system). Header compression that is faster than l2tp and that does not encrypt data, but it does hide ips. Q1: which of the following remote access protocols is the most powerful: slip, ppp, pptp, l2tp, header compression. A1: l2tp is the most powerful and slip is the least: authentication server. At the heart of network there is a server responsible for user authentication. A server os is called also network os. The following net os (nos) exist: windows server (2008, 2012), linux. Nos is referred to as a domain server.
