1. Assure security does not require user decisions.

2. Assure business justifications for all inputs and outputs in the application.

3. Quarantine and validate all inputs including app content.

4. Limit trusts (to systems and users).

5. Encrypt data.

6. Hash the components.

7. Assure all interactions occur on the server side.

8. Layer the security.
