network security and terminal security issues
-network attacks, including denial of service attacks, unauthorized
access, distributed attacks and so on.
-terminal attacks, viruses and Trojan horse attacks on USB
storage devices cannot be completely resolved.
-other problems, such as user information disclosure.
★One of the urgent & key problems that needs to be
solved in information security.
★Underlines the importance of security measures

1. Introduction
NIDS
A firewall is not the ultimate solution for network
security.
※ Total reliance on the firewall tool may provide a false sense
of security. The firewall will not work alone (no matter how it is
designed or implemented) as it is not a panacea.
※ It is inconvenient for the firewall because most information
about attacks of the firewall depends on the administrators.

2. Architecture
Most parts of this protection system are designed and
implemented in hardware to be faster and more secure.
For instance,
on the one hand, packet filtering in hardware, immunity
from ARP attacks in hardware, monitoring and
transmitting with hardware acceleration are designed and
implemented on the NetFPGA to protect the subnet from
network attacks.
On the other hand, AES and DES encryption modules in
hardware, immunity from the USB virus and Trojan horse
by physical isolation are designed and implemented on
the DE2 board to protect terminal security effectively.

-Reconfigurable Hardware Firewall
Hardware firewall with remote reconfiguration
supported
1. Reconfigurable HW firewall
packet filtering in hardware, immunity
from ARP attacks in hardware
2.Reconfigurable design
Improve performance, Reduce the cost
3. Remote reconfiguration
Updating the system via any devices
Traditional hardware firewall
Updating hardware means a lot of time and
money will be wasted
Traditional software firewall
1. Low-performance
2. Its speed and throughput is not high
