  2. What can be suggested when a gap is identified.
  1. There are no access control policies implemented to protect the stored data.
  2. If there is no protection against malicious code.
  3. Availability is a key aspect of security. If encrypting data makes data unavailable, or adversely affects availability by reducing performance, then encrypting everything will create a new security problem. In short do not encrypt everything, information classification is equally important when you are looking at drafting your information security policies.
