Currently on the market the most common intrusion detection system, the vast majority are mostly NIDS, such as Neusoft NetEye, Lenovo network defense, and the Hai Jinnuo KIDS, Venus days, Tian, NAI McAfee IntruShied, Angle LinkTrust and so on. HIDS and NIDS Although the basic principle of the same, but the method of intrusion detection, process and play a role are not the same, the main difference between them as shown above. HIDS will probe installed in a protected system, it requires the operating system kernel and services bundled together closely to monitor various system events, such as the kernel or API call, in order to defend against attacks and to log these events; also can monitor specific system files and executable file called, and the safety record under Windows NT and Unix systems in a record. For the particular set of key files and folders can also be a timely poll monitoring. HIDS can detect intrusions, the event to give a positive response, such as disconnect, sealing of the user account, kill the process, the author alerts and more. If a user in the system implanted in an unknown trojan virus, may kill all virus software, IDS, and so the virus database, attack libraries are not documented, but as long as this Trojan to work, such as the elevated user rights, illegal modify system files, calls are monitored files and folders, etc., would have been immediately HIDS discovery, and take to kill the process of sealing of accounts, or even disconnect from the network. And even now some of the lessons some of HIDS network, access control and other aspects of technology can be a good system, even the application of the system closely.
Power supply, the graphics core and memory with independent power supply design, power supply selected high quality raw materials, aluminum capacitors provide the stability for the graphics card guarantee. Graphics provides a native CrossFire cheat, user set up without the main card crossfire system. Memory section, equipped with Samsung 1.4ns GDDR3 graphics memory particles, formed the front four 256MB/128bit the memory specifications, the graphics card default core / memory frequency of 600/1300MHz, the frequency of such specifications has reached the level X1650XT , outstanding performance. Cooling, the graphics card is equipped with an open radiator, this design has a good cooling effect, while the core cooling can take care of memory and other components, and operating noise is very small. Output section, this X1650GT with a VGA, DVI and S-Video output of the three interfaces to ensure the AVIVO and the purity of 2D output signal for providing a more excellent graphics display.
