Web filtering, or the use of content control software is a vital tool to be used in organizations such as offices, schools and colleges. Making use of a web filter is very important, as it allows companies to make sure that they are able to control what content is viewed by their users/ employees. A web filter is basically a tool that runs in the background, and prevents access to certain websites that might not be friendly or helpful within the environment. The software itself is able to determine the type of content that should be allowed and the content that should be restricted. Usually, making use of a web filtering program is very important in companies, mainly because it helps in improving productivity amongst users.
Usage of a web filtering software can vary considerably, and on a number of different levels. For example, a web filtering tool can be used on a national level by the government of a country in order to prevent access to certain websites. In certain parts of the world, some websites are blocked primarily based upon their religious nature or controversial content. Then, the internet service provider can also install a web filter in order to prevent the clients from accessing certain types of content. Content control software is also very useful in libraries and schools, prevent students and visitors from accessing needless content such as social media and other websites that are not useful in such environments.
Web filtering is basically a dynamic service. Most of the programs that are used for filtering the web generally come equipped with preset databases. For instance, they will only require you to select the nature of the websites that you wish to filter. For instance, if you select 'social media', the web filter will automatically filter all websites that fall under the category of 'social media'. This makes the whole process much easier because as the user, you do not have to continuously add in hundreds of websites by hand. Most web filtering tools also come equipped with certain options. For instance, you can decide what you would want to do if somebody searches for a blocked page. For instance, if you type in a certain word that has been blocked by the web filter and search for it, the program can automatically close the browser window and show a warning message on the screen. Similarly, you can also decide to just prevent the program from opening the website. Web content programs are usually different in nature, and depending upon the level on which they are installed, their robustness might vary. Certain programs, installed at a national level to control traffic on the internet are extremely robust and cannot be bypassed quite easily. Others, however, are much easier to bypass. Usually, companies hire independent firms to create content control software, while others make use of a linear program, which can be purchased in the markets or over the internet. Either way, content security is very important.
