What are the common security models used in cyber security systems?

Security models help guide the development and implementation of effective cybersecurity practices by providing frameworks and guidelines that address different aspects of security. These models define best practices, standards, and processes that organizations can follow to strengthen their security posture. They help organizations identify and prioritize security risks, establish security controls, and align security measures with business objectives. By following security models such as the CIA triad (confidentiality, integrity, availability), Zero Trust, or NIST Cybersecurity Framework, organizations can build a robust security strategy to protect their assets, data, and systems from various cyber threats.
