1. Strategic Vision
The Identity and Access Management (IAM) policy defines the governance framework, roles and responsibilities, and procedures required to control access to information systems.
Its primary objective is to ensure that only authorized individuals can access digital resources, at the right time and for legitimate purposes.
Key challenge: making identity the organization’s first line of defense.
A formalized IAM policy helps avoid improvisation and ensures consistent, standardized, and controlled access management across the entire organization.
2. Operational Pillars
Identification and Authentication
Each employee is assigned a unique and personal digital identity, ensuring reliable identification within the information system.
Authentication relies on robust mechanisms such as Multi-Factor Authentication (MFA), digital certificates, or biometrics to strengthen access security.
Benefit: this approach ensures individual accountability and significantly reduces the risk of identity impersonation.
Access Governance (Authorization)
Access rights are assigned according to the principle of least privilege, meaning each user is granted only the permissions strictly necessary to perform their duties.
Role-Based Access Control (RBAC) standardizes permissions based on job roles, improving clarity and simplifying access administration.
Benefit: limiting excessive privileges significantly reduces the attack surface and mitigates the potential impact of human error or internal misuse.
Identity Lifecycle Management
The IAM policy governs the entire identity lifecycle, including:
– Onboarding: automatic account creation and initial access provisioning upon employee arrival.
– Internal mobility: systematic review and adjustment of access rights when a user changes roles or positions.
– Offboarding: immediate deactivation of accounts when a user leaves the organization.
Benefit: this rigorous lifecycle management eliminates orphan accounts, which are prime targets for cyberattacks.
3. Control and Compliance
The IAM policy integrates control mechanisms to ensure both security and regulatory compliance:
– Traceability: logging of sensitive actions to detect abnormal behavior and support investigations.
– Audit: periodic reviews of access rights to ensure alignment with actual business needs.
– Compliance: adherence to regulatory requirements such as the GDPR and ISO 27001, ensuring legal protection and safeguarding the organization’s reputation.
4. Modernization: Identity as the New Security Perimeter
With the rise of cloud computing and remote work, the traditional network perimeter is no longer sufficient.
Within a Zero Trust approach, identity becomes the new security perimeter, requiring every access request to be verified regardless of the user’s location.
The IAM policy therefore ensures secure service continuity while adapting to modern digital usage and evolving work environments.
