For example, when a client accesses a web page through an anonymous proxy, the client talks to the proxy and the proxy talks to the web page, maintaining the privacy of the client, such as hisher IP address. The purpose of such a proxy, or a server, is to protect the privacy of the client from the service and from other individuals who may be logging and inspecting the clients connection. Such proxies are commonly used in schools and workspaces, to pass-by potential firewalls and monitoring services in place. Students will often utilize anonymous proxies to access social networking websites deemed and blocked by the school as harming the productivity of the students. Employees of a company may try to circumvent forms of monitoring within a company that may try to track or control wh ich websites its employees are visiting. Anonymous proxies serve as a wall between the client and the service being accessed. These servers can be used to bypass the restrictions and access these services possibly blocked by the country or some other organization providing the Internet connection, while others may use it solely for the privacy that is possibly guaranteed. Risks Behind Anonymous Proxies Because of how anonymous proxies, especially those running on web pages, are designed, all data sent to the proxy servers are unencrypted. Therefore, it is possible that confidential information such as logins and passwords can be recorded by a malicious proxy server. Also, through proxy chaining, some clients could potentially fall as victims to a web page displaying a false security measures, allowing all proxies within these chains to trace the clients activities. Thus, only trusted anonymous proxies with a clear privacy policy should be used for security sake. http://advice-and.info/Communications/90496_Anonymous_Proxy.html Wed, 09 Jul 2008 06:35:22 GMT A proxy is also known as proxy server and application level gateway. It is a form of technology developed for the use of various business institutions and individuals when it comes to their network and Internet access needs. With this, a proxy acts as a computer that serves as a mediator between the computers that make up the local network of a company and the Internet or any other large-scale network. A proxys work starts when incoming data is requested by a specific computer in the local network. When this happens, the proxy ensures that the data properly enters and passes through one of its ports. Subsequently, the data is forwarded to the unit that requested it through another port. Hence, by providing a means of prohibiting the direct access between networks, a proxy can prevent hackers and unauthorized individuals from obtaining sensitive information such as the internal addresses of a group. A proxy has 2 types. These include: (1)the http proxy; and (2)the SMTP proxy. The former acts as a gateway for Internet access, while the latter acts as a gateway for email. Apart from controlling the access level of external networks, the proxy can also restrict computers within the local network in terms of the online resources they could access. This is especially useful in situations when the network administrator needs to prevent the users from opening websites they are not supposed to access. A proxy can also cache web pages. This is a feature that enables the main computer to store copies of downloaded Web pages in its hard disk. When a computer in the local network requests for an external URL, a copy of that URL is stored in the server. Subsequently, when another computer requests for the same URL, the proxy can provide the stored copy instead of getting the original one from the Internet. This, of course, minimizes the time for acquiring information. http://advice-and.info/Communications/90151_Proxy.html Sat, 05 Jul 2008 15:37:11 GMT A proxy list is a list of all the working proxy websites. A proxy website is a website which lets you surf anonymously and it allows you to access the websites which have been blocked by a content filter. How does this work A proxy website allows you to enter the URL of the website which you wish to surf and once youve entered the URL, the proxy website displays the target website in a special window. In this way, your real IP address, location are not revealed to the website and you can access it even if it is blocked by the network administrator. You can interact with the website in real-time just like the way you would have interacted with it if it was not blocked on your network. The only known problem associated with the proxy websites is that theyve a small life as other websites block the proxy websites to avoid anonymous surfing. So, its important to maintain a regularly updated proxy list in order to get the information about the working proxy websites.

This helps to limit the amount of spam, cookies, and other information from being gleaned or placed on the computer. This in turn helps to keep the computer running fast and efficiently. Cookies and other computer identification software that is placed on the computer by websites can drastically slow down the computer. These cookies and other identification softwares help to identify a computer upon reentry into the website so that items that the website thinks you want will be available. The computer can also catch a virus from such softwares because of the softwares ability to be corrupted or otherwise altered. This is one of the major reasons that people use proxy sites. In addition to the protection from cookies, proxy sites stop the gleaning of information from the computer through the website. This gleaning is often just information regarding what o ther websites that one is viewing, but can be much more invasive. The possibility of hackers and other individuals who might be using the gleaned information to steal ones identity or bank accounts is greatly reduced by using a proxy site. These proxy sites can either be true internet sites that assist one in viewing additional websites while keeping the computer safe, or they can be servers that protect the computer. Proxy sites that are true websites tend to provide secured lines of communication between the website and the computer. This helps to defray any lost or gleaned information from the computer and limits the cookies that may be placed on the computer. Servers that are used as proxy sites are often in addition to the server that allows for the computer to access a website. This server acts a surrogate computer and takes all of the cookies, spy ware, and other computer harming components for it to be trashed and destroyed before damage can be done. This server could be part of the computer itsel http://advice-and.info/Communications/87810_What_Are_Proxy_Sites.html Sun, 08 Jun 2008 06:06:52 GMT Proxy sites are web pages that provide Internet users with the ability to browse web sites that may be blocked by a content filter of some type. By making use of the proxy site as the portal to the blocked site, it is possible to circumvent the work of whatever filter is in place. At the same time, the proxy site also helps to mask the visit to the site, so that there is less evidence that the content filter was not successful in preventing the visit. How Does A Proxy Site Work? http://advice-and.info/Communications/85394_What_Is_A_Proxy_Site.html Tue, 22 Apr 2008 21:21:39 GMT If you are like a lot of people, you probably plan on traveling someday, but you just cant find either the time or the money to do it. When a person is out of work, a sense of wanderlust can start to play in their mind and they can imagine far off exotic destinations that beckon them. They are out of work though and that also means that they are short on cash, so that also means that they have to stay put and look for a job. http://advice-and.info/Communications/54143_Travel_By_Proxy_With_Dish_Network.html Tue, 03 Jul 2007 22:45:28 GMT
