Website security construction for the development of the site is very important, many sites if not pay attention to the safety of the guard is likely to cause the overall loss of doom, of course, if the webmaster can actively face the security problems on the site, that also die and mend never, then we should focus on their own site security construction?

Usually the safety of the website is to prevent the people with ulterior motives from hanging the black chain, hanging Trojan and left the back door, and now there are a lot of loopholes in the site, especially some free CMS station procedures, often because of the negligence of programmers, or webmasters in the construction of the site do not pay attention to the protection of the password, using some default password, So that the site is easily attacked by hackers, and now a lot of just getting started with the computer children's shoes, in order to verify their superb hacker technology, often will take the site, the original did not want to profit, but let personal webmaster harvest great pain! Here we say the four elements of security strategy!

One: Black chain prevention strategy, the general hacker will be in the homepage of the website or content page hang a piece of code, let the search engine that the site has exported a link, and this code is very covert, in our usual simple site maintenance is not visible, at this time can be viewed through the IE menu, find the source file, and through the CTRL Wheels to find, for example. For example: "<a href=" http://www.baidu.com/"target=" _blank "> Baidu </a>" content page. If we find out later. Can download index.php files such as FTP to delete, upload and overwrite. This basically solves the problem of being hung black chain, of course, after solving the problem, we must strengthen the security of the website through the setting of the password to ensure the security of the future website!

Second: Trojan prevention strategy, usually Trojans are in the HTML page to add an IFRAME code, and this code is easy to download through the JS script to the client, so that other people's computer infected Trojan virus, in order to solve this problem, we can query the first line of IFRAME in the initial paragraph, And then use the tools to troubleshoot, another sophisticated hacker will use the JS script language to hang the Trojan, this Trojan will be more difficult to clean up, usually from the background folder in the PHP and ASP files to find, and then in the copy to the text replacement tool, And then the whole station to replace the folder can be, if there is a master of the form of JS encryption to invade your site and carry the horse, it will be the entire site to clean up, including the database, background and server, etc.!!!!!

Third: Server security strategy, some space vendors in order to save costs, no installation of high quality of the kill soft, so that the server appears a lot of backdoor, these backdoor often by some hackers added a lot of new management account, and then the hacker took the Webshell, Although the market now on the Webshell comparison of cheap, but hackers can black space merchants to carry out the bulk of the sale, in order to prevent the server back door is attacked, we can through the SHIFT key has been several times and then prompted you can enter the background, At this time can periodically check whether there is unknown identity of the account exists, if there is to delete immediately, at the same time in a careful examination of the server inside the management group users, to see if there is no unknown users, of course, the appropriate backup is very necessary!

Four: Webshell prevention strategy, in fact, the acquisition of Webshell not only through the hack server access to the back door, we through PHP. ASP, such as injection vulnerabilities can also be obtained, so for the relevant CMS site procedures, to timely repair upgrades, the injection of these vulnerabilities are shielded, in addition to the usual learning server and site security knowledge, from a variety of ways to solve the problem of Web site vulnerabilities!

Or that sentence, site security is the most important component of the site operation, in addition to the usual security concerns, but also in a timely manner to their own site backup, so that can effectively improve the safety of the site, even if the site system crashes can be restored through backup!
