The two most dangerous types of incorrectly set permissions are the fourth biggest security issue, author says. It’s easy for a single security principal (e.g., a user) to get permission to something they shouldnt have access to. Thats a problem, but Im talking about major permission mistakes involving just two main permission types: Everyone Write/Modify and Everyone Read on files and folders that should not have those permissions. This could come about from those exact permissions set, or from some larger, even more permissive set of permissions.”]
