Enterprise
Firewall | |
The
Internet is a powerful tool for businesses,
providing virtually limitless access to
innumerable business resources. However, without
safeguards the Internet also provides external
users easy, unrestricted access to your company's
networks. Such access allows a variety of
malicious activities to be carried out without
your knowledge. In a recent survey, 72% of IT
leaders reported breaches from hostile code during
the last year.
Today, in order to protect
against these threats, virtually every
organization MUST install a firewall. A firewall
is a device that acts as a gateway, monitoring and
controlling the flow of network traffic for
security purposes. It examines all inbound and
outbound traffic; permitting only traffic meeting
certain predeterminded criteria to pass. This
blocks unsolicited traffic from hackers, while
maintaining transparent Internet access for
employees and customers. |

 |
| NAT
and Masquerading |
| Dynamic
and static Network Address Translation (NAT) and
masquerading conceal internal IP addresses
behind a "public" IP address, to prevent hackers
from learning about internal networks, servers,
and users. |

| Dos
Protection |
| A
PC CHINA All-In-One Firewall Solution protects
against common Denial of Service (DoS) attacks
like TCP SYN flood, ICMP flood, UDP flood,
Smurf, Trinoo, and IP spoofing. |
| |
| Traffic
Shaping and QoS |
| Administrators
can increase or decrease the priority of
different types of traffice between specific
endpints, providing quality of service (QoS) for
critical transactions. |
| Detailed
Reporting |
| A
PC CHINA All-In-One Firewall Solutin provides
detailed reporting on network traffic,
connections, packet filter violations, hardware
utilization on the firewall system, and other
information for managing the firewall.
Accounting reports provide detailed data on
traffic to and from network segments. |

 |
| |
| Stateful
Packet Inspection (SPI) |
| PC
CHINA's firewall inspects network packet headers
to manage traffic between the Internet and
internall networks, servers, and users. The
firewall examines individual packet headers to
make sure that they conform to the rules of the
appropriate protocol (packet filtering), and
tracks the sequence of events during ongoing
connections to detect violations of normal
processes (stateful packet inspection).
|
| |
| Application-Level
Deep Packet Filtering |
| The
PC CHINA firewall utilizes application-level
proxies to scan the application-related content
of communications packets (payloads) to ensure
conformance with rules specific to web traffic,
email, DNS, and other broad application types.
|
| |
| Security
Proxies |
PC
CHINA's firewall provides comprehensive proxies
that simplify management by allowing
administrators to quickly and easily enable and
disable protocols and features such as content
filtering, caching, whitelists and blacklists,
file extension filtering, and MIME error
checking. Proxies are included for the
protocols: HTTP | DNS | SOCKS | POP3 | Ident |
SMTP
The firewall is the foundation of
the security applications in the PC CHINA
All-In-One Firewall Solution. Applications such
as Instrusion Prevention and Gateway Anti-VIrus
work with the firewall so that traffic related
to security threats can be blocked immediately,
before infecting internal networks. Integrating
all applications in-line on the same device
improves performance by eliminating delays
associated with vectoring files back and forth
to separate systems for virus, spyware, spam and
intrusion scanning. |
