The Linux Port/Socket Pseudo ACLs project is a patch to Linux kernel v2.4 which allows the admin to delegate privileges for some protected network resources to non-root users. The ACLs are generally used to run untrusted or insecure applications as an unprivileged process, thereby lessening the impact of some undiscovered denial of service or root compromise. The ACLs can cover protected ports, raw sockets, and packet sockets.
