The NCSA Guide to PC & LAN Security
Stephen Cobb, CISSP
Chapter 13: Secure Communications
This chapter is about: WANs, remote access, and the Internet
...the chapter looks beyond local area networks to the broader aspects of personal computer-based data communications. This takes in the security of modem connections over telephone lines, remote access to personal computers and networks, wide area networks, long distance connections between networks, plus other forms of computer facilitated communication, such as fax and voice. We begin with basic outbound communications from a personal computer, then consider incoming calls, network connections.For companies active in this field check out the following Hot Links at NCSA:
