    In the implementation phase, the plan will be put into action. While doing so, it is important to ensure that adequate safeguards are in place to enact and enforce the information security policy.

  4. Evaluate

    After the security policies and plans have been implemented, it is necessary to monitor them and make sure that the systems are completely secure and operating in accordance with the policies, security requirements, and service level agreements of the organization.

  5. Maintain
