ProSecure Unified Threat Management (UTM) Appliance
analysis to stop both known and unknown threats. The malware database contains
hundreds of thousands of signatures of spyware, viruses, and other malware.
Objectionable traffic protection. The UTM prevents objectionable content from
reaching your computers. You can control access to the Internet content by screening for
web services, web addresses, and keywords within web addresses. You can log and
report attempts to access objectionable Internet sites.
Application control. The UTM provides application control for entire categories of
applications, individual applications, or a combination of both. You can either globally
allow or block applications or configure custom application control profiles for groups of
users, individual users, or a combination of both. The UTM supports multiple applications.
Automatic signature updates. Malware signatures are updated as frequently as every
hour, and the UTM can check automatically for new signatures as frequently as every 15
minutes.
Security Features
The UTM is equipped with several features designed to maintain security:
Computers hidden by NAT. NAT opens a temporary path to the Internet for requests
originating from the local network. Requests originating from outside the LAN are
discarded, preventing users outside the LAN from finding and directly accessing the
computers on the LAN.
Port forwarding with NAT. Although NAT prevents Internet locations from directly
accessing the computers on the LAN, the UTM allows you to direct incoming traffic to
specific computers based on the service port number of the incoming request. You can
specify forwarding of single ports or ranges of ports.
DMZ port. Incoming traffic from the Internet is usually discarded by the UTM unless the
traffic is a response to one of your local computers or a service for which you have
configured an inbound rule. Instead of discarding this traffic, you can use the dedicated
demilitarized zone (DMZ) port to forward the traffic to one computer on your network.
Autosensing Ethernet Connections with Auto Uplink
With its internal four- or six-port 10/100/1000 Mbps switch and single or dual
(model-dependant) 10/100/1000 WAN ports, the UTM can connect to either a 10-Mbps
standard Ethernet network, a 100-Mbps Fast Ethernet network, or a 1000-Mbps Gigabit
Ethernet network. The four LAN and one or two WAN interfaces are autosensing and capable
of full-duplex or half-duplex operation.
The UTM incorporates Auto Uplink
TM
technology. Each Ethernet port automatically senses
whether the Ethernet cable plugged into the port should have a normal connection such as to
a computer or an uplink connection such as to a switch or hub. That port then configures itself
correctly. This feature eliminates the need for you to think about crossover cables, as Auto
Uplink accommodates either type of cable to make the right connection.
