AI-suggested
European organizations should take the following specific steps: 1) Immediately verify that all Fortinet devices and FortiCloud services are updated with the latest patches and firmware, confirming patch integrity through checksums or vendor tools. 2) Implement multi-factor authentication (MFA) for FortiCloud accounts to add an additional layer of security beyond SSO. 3) Monitor FortiCloud login activity for anomalies such as logins from unusual IP addresses, times, or devices, using SIEM or cloud monitoring tools. 4) Restrict FortiCloud account access using IP whitelisting or VPNs where possible to limit exposure. 5) Conduct regular audits of FortiCloud user permissions to ensure least privilege principles are enforced. 6) Establish incident response plans specifically addressing potential FortiCloud compromise scenarios. 7) Stay informed through Fortinet security advisories and subscribe to threat intelligence feeds for updates on exploit developments. 8) Consider segmenting network management traffic and isolating FortiCloud-managed devices to reduce attack surface. 9) Engage with Fortinet support for guidance and verification of secure configurations. These measures go beyond generic advice by focusing on FortiCloud-specific controls and monitoring.
