Protecting our wireless networks to the maximum extent is a matter of great concern to us. From which aspects should we manage and set them? Here we will introduce it to you. The purpose of reasonably protecting wireless access points is to isolate wireless networks from outsiders who are not authorized to use services. It is often easy to do. In terms of security, wireless networks are usually more difficult to protect than fixed wired networks, beca

Wi-Fi is inherently vulnerable to hacker attacks and eavesdropping. However, if you use the correct security measures, Wi-Fi can be safe. Unfortunately, the site is full of outdated advice and misunderstandings. Here are some of the things you should do and shouldn't do in Wi-Fi security. 1. Do not use WEP WEP (Wired Equivalent encryption protocol) security has

A company named infoexpress believes that dynamic network access control (dnacc) technology can be used to achieve this. Network Access/Access Control Technology (NAC) generally includes hardware infrastructure or client software designed to protect network security. By using the P2P method, DNA c can change this mode,

Nowadays, many enterprises rely on wireless LAN to operate, which brings new standards for wireless security defense. Many enterprise personnel will perform some necessary wireless network security settings. This article will mainly explain the security limitations of wireless networks. This article describes restricti

The current network is ignorant of IT systems. As Gartner and other market research companies have pointed out, IT does not know which user is on the network, we also know little about Application Communication on the LAN. In fact, IT ultimately relies on encryption tools to replace user data and application data. However, these tools are rarely used to associate information with real-time communication. Ho

. This is unrealistic in most environments. 3. Be sure to apply 802.11i The WPA and WPA2 secure EAP (Extensible Identity Authentication Protocol) modes use 802.1X identity recognition instead of PSK to provide each user and customer with their own login certificate capabilities, such as the user name and password and a digital certificate. The actual encryption key is regularly changed and exchanged in the background. Therefore, to change or revoke us

processing, network management, and traffic control, this vpn-dedicated router provides a private management platform, enables secure and efficient communication. Take the di-740p model of the Broadband Router D-Link, the default Management address is 192.168.0.1, the Management port is 8080. Set the IP address of a computer and the router management address vro in the same network segment. For example, 19

Although firewalls are highly efficient in preventing network intrusion and have become a key factor in submitting Secure Web sites and services, all these security measures are achieved at a high cost. In short, the firewall limits performance and scalability. Because the firewall is an online device that may cause a single fault point, it will reduce the

expire. In this case, the normal filtering of the destination address and port number is used. Unless you invade the PIX itself, external users still cannot understand the internal network structure. Without understanding the internal network structure, a malicious user cannot execute an attack from an internal host to an internal network. Another

To partition a potential hacker to attack your Linux server, he will first try to buffer overflow. In the past few years, buffer overflow is the most common form of security vulnerabilities. More seriously, the buffer overflow vulnerability accounts for the majority of remote network attacks, which can be easily exploited. About partitions If a potential hacker attempts to attack your Linux server, he will

other user accounts are not important. This is a long-term and chronic weakness in Linux and Unix security. A simple reinstallation can replace damaged system files, but what should I do with data files? Any intrusion has the potential to cause massive damage. In fact, to spread spam, copy sensitive files, provide fake music or movie files, and launch attacks against other systems, there is no need for root access. IDS new favorite: PSAD Psad is shor

study, the final make not perfect, but the result of the correct code is still very rewarding. I learned the IO stream and the storage and reading of the files. And in this experiment, I don't know much about every single statement that a teacher has to pack into our cryptographic algorithms, but the ability to integrate them into a single piece of code is mastered, and the most important thing to learn about Java is to master the methods and architectures, which are not fully understood or app

network to send the MD5 of ciphertext and plaintext to server 3. The client and server use the DH algorithm for the 3DES or AES algorithm key exchange 4. After the server receives the suffix expression expression, decrypts, decrypts the MD5 value of the plaintext, compares it to the MD5 from the client, and then calls the Mydc.java function to compute the value of the suffix expression and sends the result
