Description: Our System Integration team continues development and improvement of own security system “NixHedgehog” for Linux and UNIX servers which represents “impenetrable shield” from hacker attacks. The first part of the system is built on “intelligent” firewall software and stack of attacks detection modules. The detection software discloses intrusion attempts and forwards info about attacker IP and ports attacked to the “intelligent” firewall where that may be temporary or constantly closed. Second part of the system guards the server data. It traces all the changes made to all files in protected folders logging the time when change made and the user who performed it. Also systems performs daily backups of all critical data. This way we are able to track where and what was changed, who done it and backup the previous versions. Third part of the system is based on standard Linux and UNIX security utilities and general security approach. All the users and groups rights are tuned; no straight root access allowed all the access and processes startup rights are configured to get maximum security and reliability. The logging system traces all the processes and all the users’ actions. All the critical data and processes are doubled. We implement this system on all servers we take on our support. It may be adjusted to different security levels and configured for any server functionality which allows us to provide real security to our customers. Usually it is used both with our distributed monitoring system, which automatically alerts us for any critical issues appeared and we always are available to access the server and fix the problem in 15 minutes. Only secure connections to the system allowed: SSH, SFTP, ipsec, pptp.
