) using symmetric encryption algorithms to address confidentiality (an important encryption method)Symmetric cryptography is like putting the rules of a common algorithm into a safe, and only getting the safe and safe keys to get the algorithm handbookAdvantages: The key encryption algorithm is very fast and solves the security problem of ordinary encryption algorithm.Disadvantage: The

WEP, so a basic principle is to set the WEP key as high as possible. Regular replacement keys It is not always necessary for all environments to change the key every week, but you should consider changing the key at least once a quarter. As time progresses, a wireless network that never replaces a

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

Today, merchants, banks and other business and financial institutions in the E-commerce boom has entered the internet, the government on the Internet as the symbol of the digital government to connect the State organs with the Internet, through the Internet to achieve including individuals, enterprises and the government's social information sharing has gradually become a reality. With the continuous expansion of the network application scope, the att

technologies are provided to provide value-added redundancy design at different levels. 3. The purpose of flexibility and flexibility is to achieve customization based on the needs of different users in the data center, networks/devices can flexibly provide various common network interfaces and reasonably match network modules according to different requirements. 4. manageability of the manageability

WEP encryption To achieve wireless network security light access control certainly not, data encryption is also essential, data encryption can guarantee that the launch of the data can only be expected to receive and understand the user, the current common methods of data encryption have WEP and so on. WEP (wiredequivalentprivacy) encryption technology is derived from the RSA data encryption technology n

. June 24, 2004, IEEE passed the 802. 11i based on the SIM card authentication and AES encryption method for wireless LAN provides security, making wireless LAN has a more extensive application space. Security mainly includes access control and encryption two parts. Access control guarantees that only authorized users can access sensitive data, and encryption guarantees that only the correct recipient can

Turn on Windows 7 's hidden features: virtual WiFi and Softap (that is, virtual wireless AP), you can make the computer into a wireless router, sharing the Internet, saving network fees and router purchase fee. iphone4 through, more convenient than conncetify, stable, good speed. A laptop with an operating system win7 or a desktop with a wireless network card as the host. (When you open a virtual wireless

tracking is the key to realize the network security practice effectively. It has brought about a major change in business activities that has greatly exceeded the effectiveness of the manual security Strategy. The current situation of business activities requires the enterprise to use an automatic detection method to

is widely used to implement Protocol encryption. Users can access the vro only by using the key. Generally, you can refer to the driver program as part of the operating system. After registration through the registry, the corresponding network communication driver interface can be called by the communication application. Network

Security Settings for home networks are a key issue for us to study. Here we will introduce several tips to help us solve the security problems of wireless networks. Nowadays, most households access the Internet by setting up wireless networks. However, many people know that many network

network interacting with the outside world, which has invasion, virus and attack. How do you protect the border? For a public attack, only the protection of a road, such as to deal with DDoS attacks, but for the intrusion of the behavior, the key is to identify the intrusion, it is easy to identify and block it, but how to distinguish between the normal business applications and the behavior of intruders,

launch attacks before enterprises discover security vulnerabilities. In this case, intruders and enterprises are playing a speed war. If enterprises can use hidden danger scanning tools to discover vulnerabilities in the network system, and take appropriate measures to resolve viruses. The vulnerability library of the RJ-iTop network vulnerability scan system of

Regarding the Security protection of Cloud computing data centers, CSA (Cloud Security Alliance, Cloud Security Alliance) put forward a total of eight suggestions in D7 of the Cloud computing key field construction guide, four security risks related to

that are directly related to virus protection. Your network security and design team should determine how to use each of the following methods in the Organization. Network Intrusion Detection System Because the peripheral network is a very risky part of the network, it is e

transmit wireless Internet signals. However, WAP protocol with high security performance is not used to protect wireless signal transmission. Even if common online users use the WEP encryption protocol and WEP key settings, illegal attackers can easily crack encrypted signals through professional attack tools, this allows you to easily intercept information such as the customer's Internet address,

to disable the DHCP function. Wireless Network Security Settings II: Encryption Nowadays, many wireless routers have the wireless encryption function, which is an important protection measure for wireless routers. Data Encryption in radio waves ensures the security of transmitted data information. Generally, wireless routers and APs have the WEP encryption and W

. ◆ Reliability of backup and replacement cannot be guaranteed: the replacement of key equipment (especially some key interface boards) generally affects the operation of services or equipment, and the success rate of replacement cannot be guaranteed at present, the switch may fail in an emergency. ◆ The reliability of the software cannot be guaranteed: there are some problems with the software versions and

storage capacity, and that the base station power meets the requirements of encryption and routing; the communication mode is point-to-point. End-to-end encryption ensures the security of data transmission. The RF layer always works normally. Based on the preceding prerequisites, typical wirelessSensor Network SecurityProblem: A.
