Nowadays, as the internet and other networks are growing constantly in our country, the need to provide security in cyberspace can be felt more than before. It is sensible reaction existing in terms of fear for damaging the moral and social principles, and of lack of mental and cultural security owing to pernicious and morally corrupted information on the internet and cyberspace on the grounds that each society has its own informational frameworks. It is natural that information trespassing these borders and lines can be dangerous to the security and moral health of society.  Although there are some upsides in regard to the global networks, misuse of networks has jeopardized privacy of individuals.
