The correct answer is A. Certification and Accreditation (C&A).
Certification and Accreditation (C&A) is a process used for implementing information security. It is also known as Assessment and Authorization (A&A) or Authorization and Accreditation (A&A). C&A is a structured process that is used to ensure that information systems and applications are secure and meet the required security standards.
The C&A process involves several steps, including:
Initiation: This involves identifying the information system or application to be certified and accredited.
Security categorization: This involves determining the sensitivity level of the information system or application based on the potential impact of a security breach.
Security control selection: This involves selecting the appropriate security controls to mitigate the identified risks.
Security control implementation: This involves implementing the selected security controls.
Security control assessment: This involves testing and evaluating the effectiveness of the implemented security controls.
Authorization decision: This involves making a decision on whether to authorize the information system or application for use.
Continuous monitoring: This involves monitoring the security controls to ensure that they remain effective over time.
The C&A process is used to ensure that information systems and applications are secure and meet the required security standards. It is often required for systems that process sensitive or classified information, such as those used by the government or military.
Information Assurance (IA) is a broader term that encompasses all aspects of information security, including C&A. It involves protecting the confidentiality, integrity, and availability of information by applying appropriate security controls.
The Five Pillars model is a framework used to assess and improve cybersecurity posture. It includes five pillars: Identify, Protect, Detect, Respond, and Recover.
The Classic information security model refers to the traditional approach to information security, which involves implementing technical controls, such as firewalls and encryption, to protect information. It is often criticized for not addressing the human element of information security.
