Linux system and server antivirus real

Second, Linux server virus protection policy described above, you can see the whole computer viruses exist on Linux system is relatively small.

However, due to various reasons in enterprise applications often is Linux and Windows operating systems coexist to form a heterogeneous network. On the server side are using Linux and Unix, and Windows desktop client. So Linux virus protection strategy is divided into several sections: executable file virus, worms (worm) viruses, script viruses through the installation of preventive killing virus software GPL Basic can prevent. The server can use avast! forLinux/UnixServers it is working at the command line, run-time can rarely consume system resources. Workstation users can select avast! LinuxHomeEdition, can run on any X-Windows environment following, such as KDE or Gnome. Prevention for backdoors can LIDS (http://www.lids.org/) and Chkrootkit (http://www.chkrootkit.org/), the LIDS are Linux kernel patches and system administrator tools (lidsadm), which strengthened the Linus kernel. You can protect the dev/directory of important files. And Chkrootkit detects system logs and files to see if a malicious program into the system, and find the associated to different malicious program signal. The latest version of Chkrootkit0.48 can detect sniffers, Trojans, worms, rootkit, 59. Proxy squid is a very good proxy server software, but there is no specific virus filtering. Consider using Germany open source enthusiasts development of a Linux-based virus filtering proxy server — HAVP (http://www.server-side.de/). HAVP virus filtering proxy server software can be used alone or used in series with the Squid, Squid proxy server enhanced virus filtering. Provides mail service is an important application in the Linux server. You can use ClamAV (http://www.clamwin.com/), full name is ClamAntiVirus ClamAV, it exposes with the same emphasis Liunx program code, free authorization, ClamAV is now possible to detect more than 40,000 kind of viruses, worms, Trojans, and at any time to update the database, there is a set of worldwide virus experts, 24-hour update and maintain the virus database, any person who finds a suspicious virus can also get in touch with them at any time and immediately update virus signatures, in a very short period of time, the network use ClamAV mail server on the completion of the latest protective action. In addition to Linux server is recommended to use command line antivirus tools, while Linux desktop application development quickly, but the command line (shell) on Linux still has a strong vitality. Even in the XWindow system administrators often have to deal with the command line, use the keyboard and mouse to be clearly higher than the number of times. For Linux system administrators, at the command line operations of importance is self-evident. Because the start X-Window-manager will consume a large amount of system resources.
