Access Control and User Management
Purpose
The purpose of this policy is to establish the requirements and procedures for managing access control and user management for cloud services. This policy aims to ensure that access to cloud resources is restricted to authorized users and is managed in a secure and efficient manner.
Scope
This policy applies to all employees, contractors, and third-party users who access the organization's cloud services.
Policy Statements
Access Control Principles
Access to cloud services must be based on the principle of least privilege, ensuring that users are granted the minimum level of access necessary to perform their job functions.
Role-based access control (RBAC) must be implemented to manage user access based on defined roles and responsibilities.
Multi-factor authentication (MFA) must be used for all users accessing sensitive cloud resources.
User Account Management
All user accounts must be uniquely identifiable and associated with an individual or a specific role.
User accounts must be created, modified, and deleted through a formal process that includes authorization from management and verification of user identity.
Temporary accounts for contractors or third-party users must have a defined expiration date and be disabled or removed upon completion of their tasks.
Authentication and Authorization
Strong password policies must be enforced, including complexity requirements, regular password changes, and prohibitions on password reuse.
MFA must be implemented for accessing cloud services, particularly for privileged accounts and sensitive data.
Single sign-on (SSO) solutions should be used where possible to simplify user authentication and enhance security.
Monitoring and Auditing
All access to cloud services must be logged and monitored continuously for suspicious activities.
Regular audits of access logs must be conducted to ensure compliance with access control policies and to detect unauthorized access attempts.
Any anomalies or security incidents must be reported immediately to the security team for investigation and remediation.
Access Review and Revocation
Periodic access reviews must be conducted to ensure that user access remains appropriate and aligned with job responsibilities.
Access rights must be promptly revoked for users who no longer require access due to job changes, termination, or contract completion.
Users must be notified of any changes to their access rights, and any discrepancies must be resolved promptly.
Training and Awareness
All users must receive regular training on access control policies, procedures, and best practices.
Users must be informed about the importance of protecting their login credentials and reporting any suspicious activities.
Compliance and Enforcement
Compliance with this policy is mandatory for all users. Any violations of this policy may result in disciplinary action, up to and including termination of employment or contract.
The security team is responsible for enforcing this policy and conducting regular reviews to ensure its effectiveness.
Review and Updates
This policy must be reviewed and updated at least annually or whenever there are significant changes to the cloud services or access control requirements.
Feedback from users and audit findings must be considered during the review process to enhance the policy's effectiveness.
