Webmaster In doing the site often will be hung on the black chain, this is some people in order to improve the site traffic and use of an abnormal means, in order to achieve the purpose of improving their own website weight, the link to their own web site linked to higher than their weight on the site, which belongs to the next three SEO methods.
To complete this action, first of all need to find the site vulnerabilities, infiltration, tampering with the target page file.
Sounds difficult, but with the hacker and other gray industrial chain developed gradually, the Internet has a lot to provide such a black chain of services.
Profitable, there is a natural gray market, once hung up, the webmaster do not carefully check, it is difficult to find.
These black chain, just like blood leech, there is no obvious feeling, neither see, nor what obvious symptoms, but your site inexplicably for some illegal sites to enhance the weight, and your own weight and search engine rankings may therefore fall.
Since the black chain has so many hazards, how do we usually find out?
1, regular view of the site source code
Does not require much advanced programming technology, also do not need special professional tools, free to look at, with the browser to open the page, the right click to select "View Source" can, in a heap of HTML code, we look for suspicious places, the most typical of these categories:
2, periodically review the file modification time
Checking file time is a way of discovering tampering, the time of the file is generally created on the creation, after the webmaster modified, try to record, and so on the next server patrol, pay attention to, if the file changes in time, then said that may be modified, open the source to see, Find out if anyone has been tampered with.
3, often modify the site's username and password
There are many ways to get a Web site or FTP username password, violent cracking, sniffing, loopholes and other ways are likely to break the line of code, so often modify the password, do not use weak passwords, such as "8888", "ABCD" Such a simple password, the complexity of the password to strengthen the letter to uppercase and lowercase + number + symbol, This will be safer.
4. Regularly check dead chain
The main is to check the availability of all links to the site, with scanning tools, such as Blackwidow, detect all links to the site, all 404 and 500 errors can be found through this tool, and if found to have abnormal external links, it is easy to find.
5, the risk of the virtual host space
Primary webmasters often choose to rent space, because the cost is cheap. Because the server is shared, security is often not guaranteed, this space server will have a large number of other sites, even if your program is not a problem, but other people's website problems, resulting in the operating system by hackers, will also be affected to their own website.
Once the black chain is hung, even if the cleaning, will be repeated later, so this situation stationmaster himself difficult to solve. At present, cloud computing in the IDC industry widely popular, renting a cloud server, not much more than the space, and security and function is greatly improved, and suggested that the webmaster to build the station in the future as far as possible not to share a server space with others.
These problems are stationmaster usually need to pay attention to, of course, want to save trouble also very simple, when get a new server, install some special black chain tool, For example, Yun Yu www.yunsuo.com.cn can be easily scanned black chain, and can be repaired, and then with the protection function, security protection, a key to fix, all resolved.
