Identity and Access Management (IAM) is a fundamental security framework within CISSP that governs how users are identified and granted appropriate access to systems and resources.
IAM encompasses several key components:
1. Identification: Establishing unique identifiers for users, devices, or systems that require access to organizational resources. Examples include usernames, employee IDs, or digital certificates.
2. Authentication: Verifying that users are who they claim to be. This typically involves one or more factors:
- Something you know (passwords, PINs)
- Something you have (smart cards, tokens)
- Something you are (biometrics)
- Somewhere you are (location-based)
- Something you do (behavioral biometrics)
3. Authorization: Determining what authenticated users are permitted to access based on their identity and associated privileges.
4. Accountability: Tracking user activities through logging and auditing to ensure policy compliance.
5. Provisioning/De-provisioning: Managing the lifecycle of user accounts from creation to termination.
IAM best practices include:
- Principle of Least Privilege: Users receive only the access necessary for their job functions.
- Separation of Duties: Critical tasks are divided among multiple individuals to prevent fraud.
- Role-Based Access Control (RBAC): Access rights are assigned based on job roles rather than individual identities.
- Federated Identity Management: Allowing authentication across multiple systems and organizations.
- Privileged Access Management: Providing special controls for administrative accounts.
- Just-In-Time Access: Granting elevated permissions only when needed for specific tasks.
Modern IAM solutions often incorporate Single Sign-On (SSO), Multi-Factor Authentication (MFA), and adaptive authentication that considers risk factors before granting access.
Effective IAM implementation protects organizations from unauthorized access, data breaches, and compliance violations while enabling business productivity through appropriate access provision.Identity and Access Management (IAM) is a fundamental security framework within CISSP that governs how users are identified and granted appropriate access to systems and resources.
