The
UltraSiG
(Secure Internet Gateway)
Full
Statefull packet-filter Firewall with VPN capability as standard.
Immediately be able to run secure Virtual Private Network between
offices and even allow secure teleworking from home.
Also built
into the UltraSiG is a fully-configurable Intrusion Detection and
Prevention System that includes a Port Scan Detector and Alerting
System that alerts the Administrator, in real time, as to the nature
of the attempted intrusion, where it came from and the details of
the Network/ISP who are responsible for the source of this attack.
Thirdly
in order of importance and significance is a Virtual Private Network
or VPN. This uses the Industry Standard and leading technology of
the IPSec set of Encryption Protocols which runs, like the firewall,
in the very heart (kernel) of the operating system and is not an
add-on software package.
To help prevent the many recent
occurances of web browser exploits in vulnerable versions such as
Internet Explorer (default on windows systems), included is a
Transparent non-caching proxy. This helps by reading the website
address or Uniform Resource Location (URL), and any redirections or
attempts by the server to open new windows, and filtering on words
such as redirection, ads, popups, banners, etc. It also filters on
words such as .exe, .zip and .dll to help prevent the automatic and
unauthorised downloading of potentially very harmful files. Any
undesirable words can be included in this. This gives the ability to
block ANY access to any site that contains downloadable executable
code such as *.exe, *.zip or *.dll, which can hide worms, viruses
and trojans for MS Windows computers. Coupled with this is a
filtering system for File Transfer Protocol, or FTP. This prevents
access to ANY FTP sites, including those that are spawned from an
internet browser session, except for those that are specifically
listed by the administrator. It also detects misuse of data packets
from the Remote FTP server and curtails the session to prevent any
breaches of security. Both of these are controlled by simple Access
Control Lists (ACLs) and redefining of the configuration files.
The
UltraProxy
(Secure Internet Gateway + Logging Web and FTP Filter)
Exactly
the same box and technology as the UltraSiG with the same
reliable service and durability but with the added function of a
logging web proxy. This takes the office users' outgoing requests
for web pages and fetches them for them while keeping a log of this.
It does this transparently, through added rules to the firewall
service, so that users' are unaware and their computer settings do
not require alteration for this to work. This system also formats
and produces a HTML-formatted web page of the daily web usage for
all office computers. This displays most sites visited, individual
user's web usage, amount of time spent on which sites, sites denied
by firewall, etc. It then uses a built in tiny http daemon
(webserver) to display these pages to the local network computers
that reside behind the firewall. The UltraProxy automatically does
this, each night, so that the previous day's full web usage
statistics are available for viewing. The user just types in the
address of the UltraProxy on their local network into their
favourite web browser for results.
Both UltraFirewalls are Diskless, Solid-State and complete with comprehensive Intrusion Detection and Prevention Systems.
