Add a range of security functions with
UTM firewalls
The 2005 CSI/FBI Computer Crime & Security Study, an annual survey the Computer Security Institute conducts with the help of the FBI's Computer Intrusion Squad in San Francisco, found that while 96 percent of the companies surveyed use antivirus software, 74 percent still got infected at least once over the previous 12 months.
Deploying multiple layers of protection is the only way to keep viruses at bay, and firewall-based scanning is a valuable adjunct to other forms of protection at the workstation and on the network. And that's where Unified Threat Management (UTM) firewalls come in.
Today's UTM firewalls add a range of security functions that used to be available as separate programs or devices, from virus protection to spam, phishing and spyware blockers.
The philosophy of a UTM firewall is simple: As long as a firewall is monitoring and analyzing data packets flowing to and from a private network, it might as well inspect for all the common security threats at the same time.
Here are three things you need to know if you're shopping for a UTM firewall:
- UTM carries a clear promise: more security that's easier to manage, requires fewer boxes and provides higher reliability. It's an obvious
advance, and the new generation of UTM firewalls offers a better value, combining a range of services into a single box that's economical to purchase and easy to manage.
- Antivirus is often the first UTM feature on the spec sheet, but protection
in the firewall is just the first line of defense. Even though firewalls see
every packet, they don't scan every data stream for viruses. Add to
those minor gaps the fact that firewalls can't penetrate encryption, like that available in many e-mail programs, and there's a clear need for added layers of virus protection.
- It's very important not to buy an underpowered firewall for use with UTM features. For example, a throughput speed rating of 90Mbps might seem like overkill for a 1.5Mbps T1, or a cable or DSL connection. And it is, until multiple UTM features are turned on. Combine antivirus, antispyware intrusion prevention and content filtering, and the performance of a UTM firewall can drop to a small fraction of its rated speed.
One last tip: Firewalls that are more than two years old are candidates for replacing or upgrading to take advantage of the protective technologies consolidated under the UTM banner.

• UTM adds another layer of defense
against myriad security threats to private
networks, which can backstop and
augment technologies already in place.
• UTM puts heavy demands on firewalls.
It may require hardware rated at up to
100 times the speed/capacity of the
Internet connection it protects.
• Plan your budget for subscription
services and support required to keep
UTM features up to date.
• New firewalls can support redundant
Internet connections as backup, reducing
the likelihood of a security problem taking
down the network.
