Unified
Threat Management (UTM) may be a term still foreign to several people, even
those curious about computers, and even many working within the industry, but
which will certainly change within the near future.
A
UTM device is that the next evolution of the normal firewall.
Most
folks have a firewall, whether we all know it or not, built into the modem we
use to attach to our Internet Service Provider (ISP). It's basic function is to
stop external traffic from entering our local private space by isolation
"ports" that are not in use. consider it as a wall between you and
therefore the internet, preventing anything from going to your computer. the
matter is that we would like some things to urge to our computer - email
traffic, web traffic etc. to permit the traffic we would like to let in we poke
a hole within the wall specifically for that sort of traffic. These holes are
mentioned as ports. Overall we are much safer with a firewall than without one,
but still the open ports present potential vulnerabilities that ne're do wells
could exploit.
Unified
Threat Management Devices combine the functions of a Firewall with an
Anti-Virus solution on steroids. Ports are still opened to permit the traffic
that we'd like to return in to travel about our day, but every packet of
traffic that passes through the UTM is intelligently scanned for Viruses,
Malware, Spam and Inappropriate Content. They also provide advanced Intrusion
Detection / Intrusion Prevention services.

recently UTM devices have started offering Data Loss Prevention services also .
With DLP you'll specify Data that's private, or your property and it'll prevent
this data from leaving the network without your specific say so. this will be
extended to automated services that monitor for things like mastercard details
to stay you safe from Data and fraud .
The
primary marketplace for UTM devices has been the tiny to medium size Enterprise
sector, thanks to the value involved in purchasing and maintaining the devices
(on top of the value of the device itself, an annual fee is payable to take
care of the filtering definitions, almost like the subscription payment on your
anti-virus software), but recently providers have started developing solutions
for the SOHO (Small Office / Home Office) market and with the increase of the
continued Ransomware threat it's only a matter of your time until options are
available for the house user market.
It
is important to notice though that whilst UTM devices provide an enormous jump
up in computer protection, they're not recommended as a replacement for
traditional Anti-Virus software, but rather an addition thereto . UTM's only
protect you from external threats and only scan traffic in transit. If your
son, daughter or spouse brings home an epidemic infected movie on a thumb drive
and plugs it in you will be wanting that AV software!
