The Sangfor HCI platform is built on a security-hardened Linux-based hypervisor. While these settings are managed by the platform, understanding them is crucial as they form the foundation of the environment's security.

●Minimal Service Installation: The attack surface is significantly reduced by disabling all non-essential system services and processes. This includes components like mail agents, graphical desktops, Telnet, and compilation tools, ensuring that only the processes necessary for HCI functionality are running.

●Core Service Hardening: Essential services, such as the SSH management interface, are configured with strict security settings to protect against common attack vectors. This includes protocol-level security and secure default configurations.

●Kernel Parameter Tuning: The hypervisor kernel is tuned to enhance security. Key parameters, such as disabling IP forwarding, are configured to prevent the host from acting as a router, thereby containing network traffic and reducing risk.

●File System Permissions: Following the principle of least privilege, file and directory permissions are set to the minimum required for system operation. This prevents unauthorized access to or modification of critical system files.

●System Authentication & Authorization: Direct root user access to the hypervisor is restricted. Privileged access requires a dual-authorization mechanism, combining the platform's admin account with a vendor-issued authorization code. This ensures that no single entity (neither the user nor the vendor) can access the system's backend unilaterally.

●Comprehensive Logging & Auditing: All critical system and kernel-level activities are logged and recorded in a "black box" audit trail. This provides full traceability, allowing administrators and support personnel to reconstruct system events for forensic analysis and troubleshooting.
