What's security management and it's branches?

Security management is the process of protecting an organization's assets, including people, information, equipment, and facilities, from various threats such as theft, vandalism, terrorism, and cyber attacks. It involves identifying potential risks, implementing measures to mitigate those risks, and responding to security incidents.

2. Information security management: This branch focuses on protecting digital assets such as data, networks, and systems. It involves implementing measures such as firewalls, encryption, and security policies to prevent unauthorized access, data breaches, and cyber attacks.

3. Personnel security management: This branch focuses on ensuring that employees and contractors are trustworthy and have the necessary security clearances to access sensitive information and facilities. It involves conducting background checks, security training, and monitoring employee behavior.

4. Risk management: This branch focuses on identifying potential security risks and implementing measures to mitigate those risks. It involves conducting risk assessments, developing security policies and procedures, and implementing security controls to reduce the likelihood and impact of security incidents.

5. Crisis management: This branch focuses on responding to security incidents such as natural disasters, terrorist attacks, and cyber breaches.
