English well, it is best to reach the level of university CET-4 level or above, this is to facilitate your reading of English documents and engaged in certain development work.(2) master basic computer knowledge, such as computer software and hardware principles, operating systems, data structures, software engineering, database systems, and algorithms.(3) familiar with the management and maintenance of common operating systems, such as Win9x/XP personal system, WinNT/2 K/2003 Server System, an

. For sniffer (sniffer), we can use session encryption scheme, all the transmitted data encryption, so that sniffer even sniff the data, these encrypted data is difficult to decrypt the restoration. Currently widely used SSL (secure Socket Layer) can facilitate the security of the implementation of encrypted packet transmission, when the user input password should be used to support the SSL protocol to log in, such as HTTPS, SFTP, ssh instead of HTTP,

Network Access Control-protecting network security Emerging cyber security threats such as viruses, worms, and spyware continue to harm the interests of customers and cause organizations to lose a lot of money, productivity, and opportunities. At the same time, the popularit

If you ask the network administrator how to effectively protect the server and network security, I am afraid 90% of them will answer: update the patch and install the firewall on the local computer. Indeed, these two measures are the most effective way to improve security. To update patches, we only need to enable the

specific mode and set the threshold value of data packet capacity from one or more sources within a specific period of time. These switches can then discard the data packet or redirect it to another destination using other technologies and protocols. Most routers and other network platforms do not have such a detailed control mechanism. 2. Attacks against specific applications and services: these attacks o

Vswitches play an important role in the enterprise network, usually the core of the entire network. In the network era where hackers are intruding into the cloud and the virus is raging, the core switch also takes responsibility for network security. Therefore, to ensure the

IOS security-network packet analysis tool Charles I wrote an article earlier: IOS development-image search (source code + resolution) Many of my friends are curious about how I got Baidu's image search API, which is actually very simple. The network packet analysis tool "Charles" can be easily implemented. To obtain the image search API, you only need to perform

Firewalls are the core and increasingly complex part of network security, and are constantly fighting against the ever-changing threats faced by enterprises. The updated firewall can analyze network traffic behavior, protocols, and application layer data. However, when resources are transferred to Amazon cloud, enterpr

With the rapid popularization of information technology, people gradually become dependent on networks. However, due to the vulnerability and complexity of network systems, network security threats will affect people's lives. Therefore, it is imperative to prevent and solve network

Campus Network Security and Prevention At present, campus networks have been widely used in colleges and universities, followed by security problems and threats in network formation and use, this article analyzes various factors that affect campus network

bound together by standard or private technologies, these technologies facilitate the portability of data and applications (for example, Cloud bursting Technology for load balancing between clouds ). When the consumption demand of products in the market is becoming more and more mature, other derived cloud deployment models will emerge. It is very important to realize this. An example of this is Virtual Private clouds-using public cloud infrastructure in private or semi-private form, resource

The problem of WLAN security has always been our most concerned. So today we are going to talk about this. Look at the network grade problem, will not affect the security of wireless LAN. Wireless connection to the community broadband network, and through the broadband network
