If you use a security policy that is already developed, be careful in adapting it or integrating it with your existing material. But they can cause readability problems too, especially if you borrow from more than one source. Much of the copied information doesn't apply to the current situation. Extraneous material and explanations are added, along with the pasted-in material. All the essential material may be covered, but it is not presented in logical order, or in a manner that emphasizes the main points and makes it easy to follow.
Copied material uses different terminology and writing styles, so the result is inconsistent.
Make sure that bulleted lists have similar items, grammatically. Bulleted lists are a compact and memorable way to convey information, but they become less readable if the items don't match, grammatically. Typically, the list is introduced by a sentence fragment, and each item in the list is an optional ending for it. So, for instance, if the list starts out as a list of nouns with modifiers, it shouldn't have any items that are verb phrases. Be rigorous in using categorizations.
