Extractions: (I am not a railroad) (IPFILTER Firewalls for OSR5) More Articles This article is generally about using SCO OSR5 as your machine. However, the concepts of using ssh to secure communications apply to any OS. Although high speed internet access may not have reached you yet, it probably will soon. The advantages are obvious, but there's a dark side: security. I'm not going to talk about the more general aspects of securing your system here (I've done that in General Security ), but only specifically about the issue of clear text passwords with telnet, pop, and ftp. Just because you have high speed access doesn't mean you necessarily want to give up your present ISP. You may not want to change your email address. You may have a web site that you need to maintain with ftp. That's my situation: my ISP hosts my mail and my web site, and I have no interest in changing that. By the way, a few things you need to think about if you are planning such a move:

All computer network devices have MACs, but in the case of a cable modem the tasks are more complex than those of a normal network interface card. For this reason, in most cases, some of the MAC functions will be assigned to a central processing unit (CPU) either the CPU in the cable modem or the CPU of the user's system.

Cable Modems And Securing The SOHO A hardware FIREWALL. I have a small LAN in my home office and really wanted to attach the LAN to the Internet via the cable modem. http://www.garykessler.net/library/cm_security.html
Extractions: April 2000 As recently as a few years ago, high-speed Internet access for the small office/home office (SOHO) was still an expensive proposition. The relatively recent emergence of low-cost alternatives such as cable modems and the variety of digital subscriber line (xDSL) technologies, however, has totally changed the calculus, making telecommuting and remote office connections over the Internet a breeze. FIGURE 1. Cable modem connection scenarios. The upper topology is most common; a coaxial cable delivers the service to a cable modem which in turn is connected to a computer via a 10BASE-T cable. The lower topology shows the cable modem connected to a hub/router that acts as the connection point for the SOHO LAN. Figure 1 shows the most common network connection topologies when using cable modems. The cable TV company runs a coaxial cable into the building to deliver their Internet service. Although fed from the same coax that provides cable TV service, most companies place a splitter outside of the building and runs two cables in, rather than using a splitter at the set-top box. The coax terminates at the cable modem. The cable modem itself attaches to the SOHO computing equipment via its 10BASE-T port. In most circumstances, the cable modem attaches directly to a user's computer. If a LAN is present on the premises (something many cable companies frown upon), some sort of router can be connected to the cable modem.
