Introduction: Define the access control and its purposes of security management.
Access control is a security mechanism used to manage and regulate access to physical and digital resources. The primary purpose of access control is to restrict access to authorized individuals and prevent unauthorized access, theft, damage, or loss of sensitive data, assets, or property.
In security management, access control serves the following purposes:
Authorization: Access control ensures that only authorized individuals can access resources, facilities, or systems. The authorization process involves identifying, verifying, and validating user credentials, such as username and password, biometric data, or security tokens.
Authentication: Access control mechanisms authenticate the identity of users attempting to access resources or systems. Authentication methods include passwords, biometric identification, smart cards, and tokens.
Accountability: Access control systems provide an audit trail of all access attempts and activities performed by authorized users. This information helps security administrators track and monitor user behavior and detect any suspicious activities.
Availability: Access control ensures that resources are available to authorized users when needed, and it prevents denial-of-service attacks that can disrupt system operations.

Compliance: Access control systems help organizations comply with regulatory requirements and standards, such as HIPAA, GDPR, PCI DSS, and SOX. Compliance with these regulations helps protect sensitive data and mitigate the risk of legal and financial penalties.
