In the process of network security detection, various DOS commands are the most handy tool for us to find clues. However, it is not easy to master the use of all DOS commands. In fact, from the perspective of network security detection, we only need to master the three commands to play a better preventive role. 1. view
Protection of wireless network security first requires the same security measures as the protection of traditional networks, followed by other special measures. In the area of wireless networking, you need to consider the problem in the face of Wi-Fi networks and devices: strong enough encryption, proper preservation of certificates, and safe operation.

With the explosive growth of digital information and the increasing dependence of individuals and organizations on these information, the storage system is becoming the center of the whole information system, and the data becomes the most important asset. However, the storage system is evolving from a local direct connection to a networked and distributed direction, making the storage system more vulnerable to attack. Events that steal, tamper with, or disrupt important data continue to occur. T
1. WiFi access 1.1 Wireless Peer-to-peer Privacy WEP (Wired equivalent Privacy) WEP uses RC4 symmetric encryption at the link layer, and the user's encryption key must be the same as the AP's key to gain access to the network's resources, thereby preventing unauthorized users from listening and access by illegal users. WEP provides a 40-bit and 128-bit length key mechanism, but it still has many drawbacks, such as sharing the same key for all users in a service area, and a user losing a key wi

). This poses an additional challenge to the selection of IPS. Because all communications need to be detected by the IPS system. Therefore, its performance will certainly be affected to a certain extent. When the number of concurrent accesses to Web services is relatively high, this negative impact will be very serious. At this time, you need to use a relatively high configuration for the IPS server to shorten the time occupied by the detection proce
