January 21, 2002 (InfoWorld) -- Distributed organizations, telecommuting, working from home -- no matter how you slice it, the home office represents one of the biggest security headaches IT departments must face. Companies are finding that it's one thing to protect systems in-house and another thing altogether to enforce standards in the spare bedroom. There's no hard-and-fast solution that will work for everyone, but by taking elementary precautions, businesses can save themselves a lot of headaches on the home front.
Some well-heeled companies may take the maximalist approach by restricting remote employees to using only company-owned PCs for accessing company-provided broadband services. Often, these devices have their configurations locked down with little difference from PCs in the company offices. This works to some extent when you have a well-defined and well-funded telecommuting program. Unfortunately, many companies haven't chosen that path.
In many cases, telecommuting policies are ad hoc, set up on a case-by-case basis. The employee, rather than the business, may make the arrangements and thus has a sense of ownership. Too often, we see home workers treated with an attitude of "You're on your own." It's understandable to expect a telecommuter to be able to handle basic systems maintenance, but not everyone has the time to become his own security expert. The result, as we've seen many times over, is a security breach.
Although the maximalist approach solves some of the biggest home-worker support issues, such as determining who is responsible for maintenance and upgrades, it often ignores the security weaknesses that exist in today's broadband networking options. A big problem is the built-in networking of Windows systems. Notwithstanding the known vulnerabilities of NetBIOS and the various LAN Manager and Windows security schemes, there's a bigger issue: When millions of machines have been configured to the same default settings, it should come as no surprise when someone in Peoria finds his system being probed by someone using a computer in Norway.
The emerging personal firewall software market offers several products that address networking vulnerabilities at the desktop level.

Troubleshooting Remote Site Networks - Best Practices
Management and remote site employees expect the same level of network service as the headquarters site. However, when IT staff are faced with limited resources to support remote site networks, often the applications, services and performance at those sites is not as robust as the headquarters site. See how to deliver a high level of network service at remote sites using the best practices outlined in this white paper.Read whitepaper now |
Super-size your LAN with fiber
Fiber optic technology frees the Local Area Network (LAN) from the confines of a single building, allowing a LAN to extend across a campus or a metropolitan area. Read how the selection of fiber optic components affects repeaterless transmission distance and how one school district used fiber to build a more reliable and more cost effective high-speed, district-wide network. Also, read how Metropolitan Area Network (MAN) ownership may require self-assessment of network performance.Read whitepaper now |
Determining the cause of poor application performance
Are users constantly complaining that your network is too slow? Or that they canât connect or can't stay connected? Are network applications hanging and slowing productivity? Do you spend way too much time trying to isolate the source of the problem and to prove that often the issue isn't the network at all but the application? In this on demand webcast, learn best practices and common root causes of application problems using case studies and live network traffic.Watch webcast now |
