whether the data packet is aggressive. Most IDS matching algorithms are similar to the multi-mode detection algorithm of Snort, an open-source Intrusion Detection System. exception detection is another IDS detection method, which is usually used as a supplement to feature matching. In the face of a variety of network attacks and intrusions, this technology needs to be constantly improved. Currently, wireless network security products are developed based on Intrusion Detection. In fact, such sec
electromagnetic shielding technology Electromagnetic Interference (EMI) is an electronic noise that interferes with the cable signal and reduces the integrity of the signal, and EMI is usually generated by electromagnetic radiation sources such as motors and machines.
the security, production efficiency, and reliability. Apart from the electromagnetic radiation sensitivity of equipment or systems, the other important point is that electromagnetic radiation that significantly exceeds the normal signal level shall not be produced, either conducting or radiating. At present, many countries control it through strict legal means What is
Integrated Wiring System is higher than the CECS72: 97 section 12.2.1 3rd of the engineering design specifications for the Integrated Wiring System of buildings and buildings: "When the interference source signal or computer network signal frequency is greater than or equal to 30 MHz, it shall exceed the standard magnitude, select different shield cable systems and shield wiring devices, such as FTP, SFTP, and STP ". The
Computer in use often appear blue screen situation, causing blue screen is also a lot of reasons, such as viruses, systems, software and other reasons. After some users ' computers have changed their memory, the blue screen disappears, but the memory is installed on the other computer can be used normally. This may be caused by electromagnetic interference. You can try replacing the CPU fan, or install the
On printed circuit boards, power cords and ground wires are the most important. The main method to overcome electromagnetic interference is grounding. For the dual panel, the ground line layout is particularly exquisite. By using the single point grounding method, the power supply and ground are connected from both ends of the power supply to the printed circuit board. The power supply is one point, one poi
What is electromagnetic interference (EMI) (Electromagnetic interference), there are two kinds of conduction interference and radiation interference. Conduction interference refers to
