Security incidents happen frequently not due to attacks that "push in" from the outside, but instead from the actions of users inside "pulling in" malicious content and programs from the Internet. This happens because of accident, ignorance, or apathy, coupled with ineffecitve or lax security policies and procedures. OpenDNS provides filtering controls accessed through a dashboard on the OpenDNS web site. Content filtering for queries from different IP addresses for up to 50 categories of content is possible. You can prevent access to adult sites, for example, or any others that you would like to choose or configure. It's also possible to denying e-mail traffic to particular domains. You can submit domains that contain malware, pornography, adware, or other undesirable content, and even vote on whether submissions by others are correct.
