nist wireless security standards

Wireless Internet technology is becoming more and more mature. Compared with network security awareness, what operations should we strengthen? I believe this article will help you. With the development of science and technology and the improvement of people's living standards, it is very common to have more than two computers in a modern family. Many families cho

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 main

using the RC4 encryption algorithm, but unlike WEP, TKIP modifies the common key, making the network more secure and less susceptible to compromise. WPA also includes integrity checking to make sure that the key has not yet been attacked, while strengthening the dummy user authentication feature provided by WEP and includes 802. 1x and EAP (Extended authentication protocol) support. This allows WPA to authenticate wireless users through the external

. Symmetric cryptographic systems require both parties to know the key, and the biggest difficulty of this system is how to securely allocate the key to both parties, especially in the network environment. 3. conclusion In the development of wireless networks, security issues are the focus of all problems, while new security measures have been added to the 802.11

Wireless Network security issues should not be generalized. The corresponding security policies should be changed for different network structures and environments. For example, for home wireless networks, encryption is relatively simple and complicated for enterprise networks. We will introduce

. 2. Safety standards: The earliest security standards WEP has proven to be extremely insecure and vulnerable to security attacks. Newer specifications, such as WPA, WPA2, and ieee802.11i, are more robust security tools. Enterprises adopting

exchanged for all group information of all clients is encrypted by different keys. No matter how much data is collected, it is almost impossible to crack the original universal key. WPA also adds functions and authentication functions to prevent data tampering in the middle. With these features, all the shortcomings that were previously criticized by WEP have been solved. WPA is not only a more powerful encryption method than WEP, but also has a richer connotation. As a subset of the 802.11i st

Financial service providers are restricted by a large number of customers' data security protection rules. Gramm-leaching-Bliley Act (GLBA Act) is widely used and abstract, but it requires risk identification and evaluation for all types of networks, implement and monitor security measures, including wireless networks. Other regulations, such as the famous Paymen

Networks initially adopted the WEP (Wired Equivalent private) security mechanism, but later found that WEP was insecure. 802.11 organizations began to develop new security standards, that is, the later 802.11i protocol. However, it takes a long time for the establishment of standards to the final release, and consider

Equivalent security mode was found to have serious disadvantages. However, the 1990s error should not be caused by wireless network security or IEEE 802.11 standard. The wireless network industry cannot wait for the association of Electrical and Electronics Engineers to revise the standard, so they launched the tempor

what intruders look like. Therefore, your MAC list contains three types of visitors: first, friendly visitors exist in the visitor list; second, no visitors in the list and unintentional visitors; third, it is not in the list, but you can be sure that you have never invited yourself and tried to break in. If they will try to break in, they can now be confirmed immediately. In short, if you detect wireless networks and find that visitors not on the MA

passwords and steal session information through man-in-the-middle attacks, or try to replay the attack. IETF and IEEE Standards Committee have already worked with leading wireless vendors because the defects in the identity authentication method used in wired networks can be easily exploited in wireless networks, establish a more reliable

, while the standards in other countries are relatively loose, for example: the maximum transmit power of Wireless LAN products in Japan is 100 mW, and that of some countries in Europe and America is about 50 mW. Currently, products sold on the market generally comply with the standards of European and American countries. When the power of a mobile phone is high,

. The antenna size and internal materials have a great relationship with the antenna gain. Why is the stronger the signal, the better? The reason is that the signal is too strong, so the range is larger, the controllable area is reduced, and the security of users is reduced. For example, although a user can receive signals in a unit with an area of more than 300 square meters in the office area, his security
