The line between functional and non-functional requirements is different for each industry, product and service. As a general rule, if a requirement is defined by your business stakeholders it can be viewed as functional. For example, information security is often considered non-function. However, if your business is related to security and your business is defining how security should function --- these are functional requirements.
