Unwanted Internet Content and its Filtering for Certain User Groups

Internet access has become widely available to almost every household. Using computers today is much easier than ever before, without need for special user knowledge. This means Internet today is available to all generations of users without special computer technology knowledge. In this work, we have presented more realistic functioning of the medium that largely confutes user perception of anonymity. The emphasis here is on content that can be found on the Internet, including potential lurking dangers, along with recommendations on how to protect from them. The business world nowadays cannot exist without the Internet, but even today there are large numbers of users, who do not use it in a proper way, which may lead to security problems for whole organizations and/or themselves. There are many possible measures for protecting users. There is education first, followed by various antivirus and other security tools which protect from malicious software, and tools that enable filtering of certain types of on-line content. These protective measures are presented in the paper, with emphasis on real-life use of certain tools for content filtering in some organizations in the Republic of Croatia.
