OpenVZ is a capsule-based virtualization technology for OS Linux which allows administrators to deploy multiple Operating Systems with different virtual hardware specifications, called containers, virtual environments, or Virtual Private Servers. In this paper, we propose new security architecture for OpenVZ depends on the type of attacks that commonly happen in servers. This security technic called OpenVzSec. The server is attacked by the client using OS windows and Ubuntu OS which is equipped with an attacker code program based on python language. Type of attacks used in this research: SSH vulnerability, SYN Flood attacks, Attack on the Rootkit vulnerability, and checksum spoofing. Some server attacks on a server and containers able to detected and anticipate by OpenVZSec. The OpenVZSec security model does not decrease performance of the server.
