A project manager is developing a portal and requests a public internet protocol address. What should the security manager do first?

The first step a security manager should take in response to the project manager's request for a public internet protocol address is to understand the business requirements of the developer portal. This understanding is crucial as it sets the foundation for effectively addressing security measures related to the portal.

By comprehending the key business requirements, the security manager can better assess potential risks associated with providing a public IP address. This knowledge will help identify the specific functionalities that the portal will offer, the data it will handle, and the potential threats it may face. Such understanding ensures that security measures align with the project's objectives while effectively safeguarding the organization's assets and complying with relevant regulations.

A clear grasp of the business needs also facilitates effective communication with stakeholders and can guide decision-making regarding security controls, access management, and incident response strategies tailored to the portal's unique context. Only after identifying and understanding these requirements can the security manager proceed to consider other actions, such as vulnerability assessments or implementing intrusion detection systems, thus ensuring a comprehensive approach to security that aligns with organizational goals.
