In addition to corporate wireless regional networks, public wireless Internet access points continue to rise ; It is worth noting that there are " public wireless internet sites" that are " disguised " to steal the user's information : A short-lived wireless network Bridge, The design looks like a real bridge to steal the user's confidential information.

I. Introduction With the rapid development of computer and communication technologies, it has become the development direction of networks to carry voice, data, images and other services through public branch networks. With this trend of business-driven and network convergence, the next-generation network (NGN) with Softswitch devices as its core emerged. NGN is

a specific architecture framework, it is important to understand the resources and services that require security analysis. IAAs covers all infrastructure resources, from equipment rooms to hardware platforms. It includes the ability to abstract (or reverse) resources and deliver physical or logical network connections to these resources. The ultimate state is

As a powerful hacker attack method, DDoS is a kind of special denial of service attack. As a distributed, collaborative, large-scale attack, it often locks victim targets on large Internet sites, such as commercial companies, search engines, or government department sites. Because of the bad nature of DDoS attacks (often through the use of a group of controlled network terminals to a common port to launch a shock, the rapid and difficult to prevent, w

. Keeping computer software in the latest version is a great help for computer security. Also be wary of shared services like Kazaa files, because these file-sharing services are a lot more traps than they were a few years ago. If you want to use this kind of software to download files, be sure to check the size of the file is not reasonable, especially to check

performance, its coverage still leads to network bottlenecks and low efficiency. Therefore, wireless services still regard it as a special service, it is not an essential inherent network function. This also leads to the slow adoption of 802.11n products. If you are considering migrating to 802.11n (how to upgrade to 802.11n at a low cost), you must understand w
