It's time to get aggressive with desktop and notebook security
During the past 10 years, there's been a growing trend toward more aggressive network and end-user security. There's certainly no shortage of threats to defend against. These threats range from relatively passive threats, such as phishing and malware, to more malicious threats, such as botnet attacks and self-propagating worms.
The latter can cripple your company financially without warning, without mercy and, more disturbingly, without provocation or end-user interaction. All it takes is one compromised machine being brought inside the network to undermine even the best traditional perimeter defenses, prompting many businesses to take a hard look at employing a redundant desktop and/or notebook PC firewall on user machines.
The double whammy
While desktop firewalls are an emerging trend, running a notebook firewall is the de facto standard. Anyone on the same wireless network as you has an unblocked connection to your computer, and it's important to protect yourself.
Microsoft Windows XP and Vista operating systems include a built-in firewall, but some organizations won't want to rely on this alone to keep desktops safe. Consider this: Windows XP's firewall was successfully compromised and disabled on some fully patched XP machines in 2007. So, many businesses take a dual-prong approach — using the firewall built into Windows for desktops while deploying a separate firewall for portables. This approach provides an added level of protection for notebooks. By applying a third-party solution, you add a layer of "security through obscurity" because to bring the firewall down, malicious code will have to be engineered against whatever specific software you are using.
When do you go for a desktop firewall?
First, determine how much you are willing to spend to get a higher level of protection. There are freeware client solutions available, and many of their developers expect to subsidize losses with support fees, while commercial products often come with free technical support or comparably cheaper support subscriptions.
Second, determine whether your company needs a highly customizable firewall or a "set it and forget it" option that hides client machines. While a solution that allows for centralized deployment and costs more may look more expensive in an organization with several hundred clients, the scalability of such a solution may more than make up for the cost if it saves your company valuable employee time and help-desk resources.
Train the software
If you choose to implement a centralized security solution with a common firewall access policy, it may be a good idea to test it on a small group and build a database of trusted behaviors and program activities before rolling it out companywide. The first few weeks that you run any software firewall solution, you will likely be prompted dozens of times by that program, asking if you want to allow an activity whenever network access is involved.
There are several programs that you will inevitably be asked about — some several times. The most common "suspects" are e-mail clients, such as Lotus Notes and Outlook; virtual private network (VPN) clients; FTP services/clients; Internet browsers; remote connection clients; software that automatically checks for updates, such as Adobe Reader or Java; and even some Wi-Fi utilities.
As a general rule, if it wants to talk to the Internet, you should take a good look at it. And the longer you train the software before creating a centralized policy, the fewer calls you will have coming into your help desk once that policy is in place.

clogs the Internet with traffic, allowing
a malicious hacker to steal or corrupt
data stored in an infected system.
