dialup security

By hhaines ·
I am reviewing a design document for a law enforcement system. The customer wants to use dialup and the internet for its communications and data base maintenance. The staff in the field will enter information into the system and recieve information. I am bothered by the dialup aspects given the confidentality of the information that can be accessed but I do not know enough about current technology to know if I should be concerned? Any suggestion of material I could use to research the issues would be appreciated.

It sounds as if your client wants to use the Internet as the backbone for dialing into a presumably secure site.

This can be done through different means:

1: You can still use the dial in method if money is a restriction, to make this safe I would recommend that the dial up be made and then use PPTP (Point To Point Tunneling Protocol), if you have an NT server you can configure it to do so.

2: If money is not so much of a restriction then you may want to think about installing CISCO routers at either end and creating your own VPN (Virtual Private Network).

Both PPTP and VPNs work in the same way, they both provide a means of transporting normally unsupported protocols through the internet e.g. NetBEUI or IPX/SPX (the internet only uses TCP/IP), they also encript the data from end point to endpoint, thus ensuring data integrity.

Establishing these types of connections would take to long to explain so what I recommend is, for configuring PPTP on an NT server (or Win2k) for a client to access visit the knowledge base within the Microsoft website. You may also want to buy or at least read a VPN configuration book to understand the technology before attempting to implement it. CISCO sell books on exactly this topic and will provide you with detailed technology aspects aswell as configuration options when creating VPNs through CISCO routers.

Hope this points you in the right direction.

Is callback feasible? Have the client call in and authenticate and have the system call them back to attach and transfer.

Hi there

If you are using either a VPN from your ISP or a VPN from 2 Cisco routers of your own example (Cisco 7200 ), additionally as I see it you might want to get an Secure Dial UP, for that matter you can use this link:
http://webferret.search.com/click?wf,secure+AND+ID+AND+card+AND+IT,,www.betanet.co.uk%2Fsecureid.htm,,hotbot if the link is not working www. betanet.co.uk
search for secure ID or look around the page or try to call them it is a very strong encryption and can not be BROKEN.
