Due to its vast capabilities and its cost-effectiveness, cyberspace plays an extremely important and decisive role in the lives of human beings today. Moral security in cyberspace is one of the critical and important issues in the modern world, which has gained even greater significance due to advancements in information and communication technology. Using a descriptive-analytical method, this research aims to examine the impact of cyberspace on moral security, and the results indicate that one of the consequences of cyberspace is the endangering of moral security. Superficiality and the weakening of beliefs, the promotion of improper hijab and unconventional attire, the spread of false ideologies, the erosion of boundaries in communication with non-mahrams, the promotion of illicit relationships (adultery), homosexuality, and masturbation are among the damages of cyberspace that affect the individual and social morality of humans. Effective solutions in cyberspace to ensure moral security include validating spiritual needs, controlling the senses and rejecting devilish thoughts, enriching leisure time, and defining values and role models, in order to reduce the negative effects of cyberspace on humans in the realm of individual and social morality.
