I think the content of the argumentative paper includes three aspects: 1, what it is (what is information security, here you should have a general argument, such as its connotation and extension), 2, why we should attach importance to it (in fact, it is the importance of information security, here you should cite many positive and negative arguments), 3, how to protect information security (personnel, technology, law, etc.), 4. The sentence is rigorous and fluent.
