Integrated Firewall/VPN/IDS
on a PCI Card Protects Desktops and Critical
Servers
The SG635
is a cost-effective firewall/VPN/IDS solution
packaged on a PCI card. By offloading all firewall,
VPN, and IDS processing from the host computer,
the SG635 ensures high performance and throughput
with the convenience of remote management and
simplified installation. Unlike "co-processing"
products, the SG635 is an advanced, self-contained
multi-tasking stateful firewall, VPN, and IDS
appliance. It includes a RISC processor, encryption
accelerator for IPsec VPN traffic and two Ethernet
interfaces for host and LAN communications.
The SG635 packs the power of a firewall, VPN
and IDS solution while eliminating the cabling,
space and power requirements of an external
appliance.
Worms and
viruses continually exploit popular desktop
operating systems making it impossible to connect
an unsecured, un-patched computer to the Internet
for any amount of time without risking exposure
and infection. Businesses can be infected by
these worms before being able to download the
necessary security patches from vendors such
as Microsoft. The primary issue is that the
time to locate download and install critical
patches can exceed the infection-free survival
time. According to The SANS Institute, survival
times of vulnerable Windows XP systems are now
as low as 15 to 20 minutes. An SG635 in every
computer can alleviate this potentially catastrophic
situation.
Fully Integrated
IDS Assures Maximum Security
Although
all SG firewall/VPN appliances defend against
Denial of Service and other common attacks,
the SG635 raises the bar by detecting "suspicious"
activity before it escalates into a full-blown
network intrusion.
Supports a Defense-in-Depth
Security Strategy
While perimeter
firewalls are effective in stopping incursions
from an external network, they cannot prevent
attacks that originate within the protected
network. Since up to 90% of network attacks
are made by disgruntled employees, an effective
security policy must include a multi-layered
"defense"-in-depth strategy. The SG635
makes this possible by complementing perimeter
defenses with "embedded" firewalls
that secure critical servers and host systems.
Multiple
SG635 adapters can be deployed throughout a
network to create a robust distributed firewall
that continues to operate when host systems
fail or become unresponsive. Like all SG firewalls,
these can be configured and managed with the
SG Central Management System (CMS).
Administrators
can define and implement access rules that restrict
desktop users to specific servers or network
resources based on their user profiles or group
affiliations. For example, a human resources
manager may be allowed to access employee records
on the HR server, but prevented from changing
payroll information stored in the accounting
system.
In addition, regulatory initiatives, such as
the Gramm-Leach-Bliley Act in the United States,
impose significant penalties on businesses that
fail to address privacy concerns by permitting
unauthorized access to personal information.
A defense in depth strategy can mitigate this
exposure by demonstrating that the organization
has conformed to all regulatory requirements.
Protect Servers on
a DMZ and Hosts within the Data Center
In
order to permit transparent public access, Web,
e-mail and FTP servers are usually placed on
an Internet-facing network or DMZ that imposes
relatively few access restrictions. The SG635
makes it possible to secure each of these servers
while preserving transparent access from the
Internet. The SG635 can also protect critical
servers in the corporate data center or application
service provider environment.
