Vendor privileged access management is the process of managing and securing the privileged access of third-party vendors who have access to an organisation’s critical systems, data, and networks. Here are some best practices for vendor privileged access management:
- Implement Access Controls: It is important to have proper access controls in place to limit vendor access to only the systems and data they need to perform their tasks. This can include implementing role-based access controls (RBAC) and limiting access to specific times and locations.
- Use Strong Authentication: Vendors should be required to use strong authentication methods, such as two-factor authentication (2FA) or multi-factor authentication (MFA), when accessing the organisation’s systems and networks. Do not introduce a new identity (e.g. a mirror), instead use federation to their existing employer Identity system.
- Do no allow shared passwords (e.g. account per company)
- Monitor and Audit Activity: Regular monitoring and auditing of vendor activity can help detect any unauthorized access or suspicious behavior. This can include logging and reviewing all vendor activity and implementing real-time alerts for any unusual activity. Audits should be fine-grained, per resource, per transaction, rather than general “accessed something in these hours”.
- Use Secure Remote Access Methods: When providing remote access to vendors, it is important to use secure remote access methods, on a per-resource basis. Use a Zero-Trust Network architecture rather than a ‘secure’ remote desktop or VPN.
- Train Vendors on Security Best Practices: Vendors should be required to undergo security awareness training and be educated on the organisation’s security policies and procedures. This can help ensure that vendors understand their roles and responsibilities and are equipped to handle sensitive data and systems securely.
- Regularly Review and Update Access: Regularly reviewing and updating vendor access privileges can help ensure that access is still necessary and appropriate. This can include revoking access when vendors are no longer needed or when their contracts expire.
By implementing these best practices, organisations can better manage and secure vendor privileged access, reducing the risk of unauthorized access, data breaches, and other security incidents.
