The Department cannot protect the Internet alone . We need help from all peoples - including you - to make smart and safe online decisions . Once we understand the dangers online , we need to tell other people who might not be as cyber smart and savvy . Setting a good example of online behavior is something you can do right now to make a difference . If we all become more aware of who we talk to , what we say , and what we share – we can all make a big difference . ( Homland Security Page )
