What aspect of information security does security architecture address?

Security architecture fundamentally relates to the frameworks and controls surrounding security processes within an organization. It encompasses the design and implementation of security measures that safeguard information systems against threats. This includes creating policies, defining roles and responsibilities, establishing security protocols, and ensuring compliance with regulations.

An effective security architecture aligns with business goals while providing a structured approach to managing risks associated with data and information systems. By establishing a coherent framework, organizations can better manage their security posture, respond to vulnerabilities, and implement necessary controls to protect data integrity, confidentiality, and availability.

The other options, while related to aspects of information security, do not directly reflect the overall design and strategy that security architecture encapsulates. The physical layout of data centers, software licensing agreements, and user training programs are important elements of an organization's security landscape, but they do not capture the broader scope of what security architecture aims to address.
