NORCO EMB-4852 Application in the Network Firewall
1. Application Background:
Network information has been sweeping the world. Enterprises and institutions are increasingly dependent on the daily work of a computer network system. The
applications of computer network technology greatly enhance the working efficiency, but the openness of the network also has posed a severe of test to the
enterprises. How to control the system resources, protect data, prevent the virus that has becoming the first considered issues of company.
2. System Overview:
In order to help customer build efficient and secure network platform, to protect data and resources security, network firewalls came into being. Network firewall is
security barrier between internal and external networks, private and public network. And it handles the information of network safe, so that internal network users from
unauthorized users interference, limited the user’s non-standard operations, effectively prevent the hacking of the computer system sabotage.
Firewall is divided into a hardware firewall and software firewall. With the repaid development of broadband networks, the software firewall lack the ability when face the
large data traffic. Hardware firewall combination the hardware and software architecture, integration industrial embedded motherboard, its performance is more stable
and data processing ability is improved. It rapidly becomes the focus under its own advantages.
3. System Functions:
1) To prevent unauthorized users access to the internet network
2) Constantly monitor network operations status
3) Generate internet activity log, make sure the hackers document be recorded
4) Automatic alarm under attack
5) Hide IP, when the hacker penetrating, it only can detect the firewall, and cannot attack directly.
4. Solution:
To enhance the firewall safety, we ask the hardware and software are perfect. As hardware, CPU processing power
and memory capacity are an important measure. NORCO developed a series of network firewall hardware products to help customers build high-stability, strong
expansion, low power consumption network security platform. EMB-4852,onboard Intel Atom N270 processor, with Intel 945GSE+ICH7M chipset, support DDR2
400/533MHz, system memory up to 2GB, and own 4x Ethernet interfaces. EMB-4852 own security, high-capacity storage and network in one, to greatly reduce the CPU
burden and the security is more desirable.
5. EMB-4852 Feature:
1) Processor: Onboard Intel Atom N270 processor,1.6GHz frequency, FSB 533MHz, L2 Cache 512KB
2) Chipset: Intel 945GSE+ICH7M
3) Memory: One 200Pin DDRII SO-DIMM slot, support DDRII 400/533 MHz, capacity up to 2GB
4) Display: Intel 945GSE integrate display controller, support VGA and LVDS,DVI output is optional
5) Ethernet: 4x Realtek 8111C Gigabit Ethernet, PCIE_1X network controller
6) Interface: Mini-IDE/2 SATA/4USB2.0/LPT /2COM /PC/104-Plus
Architecture:
6. Advantages
1) With NORCO embedded hardware, takes high processing speed, high throughput, still stable operation when in high-traffic environments.
2) Using NORCO industrial level motherboard, high performance, ensuring 24 working hours without a break
3) Dedicated firewall hardware platform, multi-network interface design, support PC/104-Plus expansion, ensuring the firewall easy to access under a variety of network environments
4) With the means of hacking and virus updates, firewalls must be timely upgrades. NORCO nationwide sales network can provide service and technical support timely.
7. Evaluation
For the firewall products, its physical properties are higher, its network processing will be power, and then its data processing ability will be more efficient. NORCO
embedded hardware product EMB-4852 onboard Intel Atom N270 processor, using a large number of cutting- edge technology to help customer to construct a safe,
efficient, reliable, easy to use, upgrade and flexible firewall, excellent performance guarantees makes the product particularly suitable for the complex network
structure high broadband to large flow application firewall system.
