TELAXIAN SHIELD™
firewall server
PRODUCT DESCRIPTION
Network Engineering Software's Telaxian Shield is the world's
first enterprise firewall designed for network protection against
external (Internet) hackers and unauthorized internal (Intranet)
access.
Telaxian Shield features include:
- New Envoy Technology
- New Secure Convoy Technology
- Multi-Sided
- Multi-Layering
- Multi-Homing
- Multiple Layers of Encryption
- Programmable Transparency
- Out of Band Authentication
- Load Sharing
- Enhanced Logging
- Enhanced Security
- Enhanced Licensing, Upgrades, and Maintenance
- Address Reuse
- Configurator
- Browser or Text Editor Configuration and Administration
In the recommended configuration, the Telaxian Shield operates
on a dedicated computer (running only an operating system and
the Telaxian Shield application) connected between the router
and private networks. This configuration forms a physical barrier
between the public and private networks using circuit and/or application
gateways. All passage to (and from) the private network must
pass through the Telaxian Shield. Individual envoys greet each
access request at the port. If the access request meets all of
the programmed security requirements for passage, the envoy facilitates
a connection between the networks. After establishing the connection,
the envoy monitors the connection and the closure of the job,
continuing to ensure the security of the users.
TELAXIAN SHIELD CONFIGURATION
There is absolutely no reason to punch holes in the Telaxian Shield.
Public accessibility is made possible by placing the WWW and
FTP servers on the outside of the Telaxian Shield. This
Telaxian Shield configuration maintains the Shield's integrity
and secures the private network behind it.
THE TELAXIAN SHIELD ENTERPRISE
The Telaxian Shield is the only firewall product on the
market that mirrors the corporate enterprise structure to provide
networks with protection against external (Internet) hackers and
unauthorized internal (Intranet) access.
PRODUCT FEATURES
Envoy Technology
The Telaxian Shield's inspiring new envoy technology facilitates
the first truly transparent connections across multiple layers
of individually configured firewalls. Envoys are intervening
processes that can be individually configured to facilitate secure,
one-step, transparent connections through Telaxian Shield firewalls,
despite the number or configuration of firewalls on the destination
path. Envoy technology combines the security of proxies with
the transparency and ease of packet filtering.
Secure Convoy Technology
Convoy technology is a secure data transport and storage system.
Information sent over a public network is received by Network
Engineering Software's Sky Light™ web server's client module
program which regulates the flow of data as preferred by Network
Engineering Software's Zero Exposure™ transaction server.
Sky Light holds the data in memory only long enough to encrypt
it; no convoyed data is stored on the Sky Light disk. The encrypted
data is then routed directly through the Telaxian Shield and deposited
in the Zero Exposure for decryption, processing, and secure storage.
Multi-Sided
A multi-sided firewall has multiple network interfaces operating
on a single Telaxian Shield firewall server. Configuring multi-sided
Telaxian Shield firewall servers reduces the cost of operating
a shielded corporate enterprise system.
Multi-Layering
With the ease and usability of a single firewall, multiple layers
of Telaxian Shields can be configured to protect highly sensitive
data, individuals, departments, or locations within a private
network. A corporate enterprise network already using a Telaxian
Shield to protect itself from Internet hackers, might also protect
itself from unauthorized Intranet access by, for example, placing
its finance data behind a second Telaxian Shield. Using the above
methodology, networks can configure any number of Intranet Telaxian
Shield layers to ensure internal network security. Multi-layering
employs programmable transparency to facilitate transparent connections
across multi-layered firewall configurations.
Multi-Homing
Using multiple network addresses on a single network interface,
multi-homing creates multiple, independently configurable "virtual
hosts" on a single Telaxian Shield firewall server. Via
the Internet, multi-homing allows networks to connect securely
and form a "virtual network" with the same communication
ease as a LAN.
Multiple Layers of Encryption
The Telaxian Shield allows networks to configure multiple layers
of encryption methodologies between multiple layers of Telaxian
Shield firewall connections.
In the example above, a corporation's New York and California
offices could shield their corporate LANs behind Telaxian Shields
to prevent external (Internet) hackers. Similarly, the New York
and California offices could then protect their finance department
LANs behind a Telaxian Shield to guard against unauthorized internal
(Intranet) access. For further security, the firewalls could
be configured to use different methods of encryption between each
firewall connection. For example, the California finance department's
LAN could be programmed to use DES encryption when connecting
to the Telaxian Shield guarding the corporate LAN. A second encryption
methodology (such as Triple DES) could be programmed for the California
and New York corporate LANs to connect over the Internet. Finally,
the Telaxian Shield protecting the New York corporate LAN could
use RSA encryption to connect to the Telaxian Shield in front
of the New York finance department's LAN. With the ease of one
connection to the first Telaxian Shield, the California office's
finance department can transparently connect with the New York
office's finance department shielded from Internet and Intranet
security breaches by four Telaxian Shields and three different
encryption methodologies.
Programmable Transparency
Programmable transparency is the feature whereby envoys are programmed
to facilitate transparent connectons on multi-home sites, despite
the number of Telaxian Shield firewall servers on the destination
path. The Telaxian Shield's programmable transparency feature
masks the firewall operations between networks because passage
does not need to go through or around the Telaxian
Shield; rather, it occurs on the Telaxian Shield by using
multi-homing connections. For users connecting with a multi-home
site and using the programmable transparency feature, there is
no indication that the Telaxian Shield exists, even though it
is still securing and monitoring the connection.
Out of Band Authentication
Before deciding whether to allow or disallow a connection, the
out of band authentication feature requires a one-time password
(of any length) to be relayed to the user via pager, fax, telephone
message, or any other token technology. Out of band authentication
can also employ S/Key, Secure ID, and other token technologies.
Load Sharing
Load sharing assigns connections across parallel configurations
of Telaxian Shield firewall servers. This feature aids speed
and efficiency and acts as a backup in the event of hardware failure.
Enhanced Logging
Each multi-home site on the Telaxian Shield firewall server can
log authorized connections and break-in attempts. In addition,
the enhanced logging feature can notify the system admnistrator
of attacks and create statistical analysis of all connections.
Enhanced Security
Each multi-home site on the Telaxian Shield firewall server can
be configured to create individual allow/deny access rules and
passwords. This feature secures network connections and shields
each multi-home site from other multi-home sites on the same network
interface.
Enhanced Licensing, Upgrades, and Maintenance
Network Engineering Software's Automated License Manager
(ALM) enables customers to purchase, download, and license the
Telaxian Shield firewall server software over the Internet 24
hours a day, 365 days a year.
Address Reuse
Addresses of computers separated by Telaxian Shields are shielded
from the Internet router. This allows enterprise networks to
reuse the full range of address possibilities.
Configurator
The configurator is a graphical user interface (GUI), accessible
remotely through a secure port and used with a web browser to
configure the Telaxian Shield.
Browser or Text Editor Configuration and Administration
For further enterprise-wide convenience, the Telaxian Shield requires
no UNIX fluency for on-site or remote configuration and administration.
System administrators can configure the Telaxian Shield by using
the configurator with any web browser or (if preferred) by using
a text editor.
