• A. Conducting a risk assessment
• B. Developing a security policy
• C. Training staff
• D. Installing software

Answer: (B)

The first step in implementing security services and mechanisms involves developing a security policy. A security policy serves as a foundational document that outlines an organization's approach to managing and protecting its information assets. It establishes the framework for all security protocols, procedures, and practices.

By creating a comprehensive security policy, organizations can define their security objectives, specify roles and responsibilities, and outline acceptable usage, access controls, incident response, and compliance requirements. This foundation is critical because it guides the subsequent steps, such as conducting risk assessments, training staff, and implementing technological safeguards. Without a well-defined policy, organizations may struggle to implement effective security measures or respond adequately to security incidents.

In contrast, conducting a risk assessment, training staff, and installing software are essential components of a security program, but they are typically carried out after there is a clear security policy in place that directs these actions and prioritizes security needs.
