NIST Special Publication 800-12 lists some essential tasks that are necessary to keep an organization’s information systems secure and compliant. It is the responsibility of the system owner, an organizational authority, to acquire, develop, integrate, operate, maintain, and eventually dispose of its system. This person makes sure the system complies with information security regulations and users’ operational needs. In addition, they have to create and manage the system security plan, make sure the system is set up and run according to the security requirements, and fix any possible security vulnerabilities. The System Security Officer (SSO) is responsible for maintaining the system’s operational security posture in close collaboration with the system owner. It is their duty to supervise the day-to-day security operations and upholding compliance with security policies and procedures. Maintaining a strong security posture and consistently overseeing system security are crucial tasks for the SSO. The role of information security architect is also essential to safeguarding the company’s systems. This individual ensures that information security requirements are taken into consideration in the corporate architecture, including reference and solution models.To guarantee that security considerations are incorporated into the system architecture, they serve as a liaison between the enterprise architect and the security team. To make sure that the organization’s primary goals and operational procedures are sufficiently shielded from security threats, the information security architect is essential. When combined, these positions guarantee the efficiency, safety, and robustness of the business’s information systems and continuously improving security measures to safeguard against evolving threats.
