Our secure Tor 主機代管 implements security at every layer of the stack. At the hardware layer, ECC RAM detects and corrects memory errors that could be exploited. At the storage layer, LUKS full-disk 加密 with keys held only in RAM ensures data-at-rest protection. At the OS layer, a hardened kernel with grsecurity patches reduces the attack surface of the kernel itself.
Mandatory access controls using AppArmor confine every process to its minimum required permissions. The Tor process can only read its configuration and write to its data directory. The web server can only access the document root. 資料庫 processes can only access their data files. Even if an attacker exploits a vulnerability in one service, the mandatory access controls prevent lateral movement.
Network security follows a zero-trust model. Every service runs in its own network namespace with firewall rules that allow only explicitly defined connections. The web server can connect to the application backend. The application can connect to the 資料庫. Nothing else is permitted. This micro-segmentation limits the blast radius of any single compromise to just the compromised service.
