Secure your server with LIDS
The Linux Intrusion Detection System (LIDS) is a kernel patch for both 2.4 and 2.6 kernels that adds Mandatory Access Control (MAC) and other security enhancements to the Linux kernel. The main feature of LIDS is its ability to limit the power of the root account. LIDS uses Access Control Lists (ACLs) to control access to files, processes, and network resources. Once these permissions are set, they cannot be overridden, even if a user or process has root privileges.
