The firewall took the network security system the
foundation equipment, its function is shuts off is controlled the
network the correspondence host skeleton line, to through receives
controls the skeleton line any correspondence to carry on safe
processing. At present the firewall mainly has the package to
filter, the application proxy and the condition examination and so on
several kind of types.
[ System principle >
The firewall security performance is decided by the
firewall whether based on safe operating system and whether uses the
special-purpose hardware platform. The application system
security performance is take the operating system security performance
as the foundation. At the same time, the application system own
safe realization also directly affects the overall system security,
enhances the firewall the reliability usually is takes the measure in
the design, the concrete measure is enhances the part the strength,
increases the design valve value and the increase redundant part.
Therefore, redundant reliable, the belt redundancy design
industry computer becomes the network security profession and the
system integration business first choice.
The present firewall general sign matches three networks
connections, separately connects exterior net, internal net and SSN.
The hardware platform has may expand and may the promotion,
ground the auspicious intelligent science and technology limited
liability company specially to produce many patterns Shan Wangkou, the
double net mouth, four nets mouths, the multi- nets mouth industry
level motherboard for the network profession user research and
development, has provided the complete choice for all networks
customer.

[ System appraisal >
1st, all securities and the service complete by the
industry level hardware equipment:
Security software in the movement, the memory is cannot
safeguard the security, software moves when very many important
information can clearly appear in some time in the computer memory,
thus "the high level" illegal member steals and uses these important
information to be extremely easy, therefore uses the hardware platform
which industry computer builds by "EVOC the", has safeguarded the
overall system security.
2. overall systems are practical reliably:
"EVOC the" industry computer is based on the PC main line
industry computer, can satisfy the synthesis operational channel the
actual need, the movement reliable is stable.
3. wholes system design:
The system not only depends upon the independent safe privacy
equipment, moreover carries on the consideration from the entire
firewall system security angle, has carried on the whole design, has
guaranteed the system security, the secrecy.
4. easy to operaties, the operation simple, the maintenance are
convenient.
