File server hosting a lot of people are familiar with, the server hosting refers to the purchase a server, then managed to the room equipped with IP, configuration such as bandwidth, and have professional and technical personnel for 7 * 24 hours on duty, in order to ensure the server and stable operation, thus make the site more stable operation,

How to keep running managed server

First, the security of the application software on the server
On the server not to install the software server has nothing to do with you, including the Windows operating system and the Linux operating system and so on, is recommended to install the latest version of the application software, such as FTP under the Windows operating system software Serv -u, believe that in the case of the server was hacked, more than 80% of Serv - U because server version is too low, coupled with the rest of the holes and invaded, a new version of the application software were introduced, has its reason, of course,

Second, the website and database security
Sometimes users upload data directly to the server, the web site set up, the client has access to whatever, this is the wrong approach, database after installation, do we have to play the latest database patches, and some basic permissions set, a web application on to the server, must be timely corresponding related directory permissions set, this will not be able to guarantee the safety of the whole server, but at least can greatly reduce the possibility of the server was invaded,

Third, the service and port
System for the first time after installation, start the many services and some of these services is the core service, some of them are unnecessary services, likewise, a service must be open to the outside one or more ports, can completely in the system after installation, will these unnecessary service and port to shut down immediately, to strengthen the security of the system to some extent,

Fourth, antivirus and firewall software
For firewall, many users server installed anti-virus software, and install a firewall, or was hacked into, it may be your anti-virus software, there is no configuration or upgrade the virus may also be no firewall configuration, a lot of friends will make the mistake, installed antivirus software as the application of ordinary, it is no longer tube after install complete restart, this is a bad habit, installed anti-virus software, should be in the first place after server restart within to upgrade to the latest virus or signature, and some simple configuration, such as boot scanning, scan or regularly scan into the system, etc., with a no escalation of antivirus software and antivirus software didn't too much difference,

Also, after you have a firewall installed, also need to make the corresponding Settings, such as ban external computer ping this computer (in fact, the function is the most basic function of any firewall), forbid not commonly used to connect applications (don't put the system update or antivirus software to add), and so on,

Fifth, other
The above several points, which are frequently used just does not mean that the server is absolutely safe, main is according to actual situation of each different application server, the security policy is not the same, at the same time, the security of the each link is very flexible, but as long as grasp the key point, your server will be considered the safe, it is open to the public service (port), at least as much as possible behind is to do the maintenance,

I wonder whether there are any to above points to close some useful Suggestions, also want to kiss in the use of products can avoid these problems
