is also a rainy week, home to the computer to their brains charged, more concerned about Seozac this blog, a lot of articles written to give people feel the nail on the head, the strength of this station how? in Baidu directly search SEO, the home page has his ranking, so the strength of the aspects do not say more. But it is such a cow x site, Site page is also hacked, but the hacker is polite, did not change any visual effect, but if you look at the next page of the blog, the problem comes out:

A few days ago just read the article, about seowhy was black, these sites are using a very mature program development, but still be black, most programmers are in the network company, not to mention our own peacetime do business station. I do some of the stations, there have been black helpless, so Fine think up, or very worried, from their own experience to give the following suggestions for your reference:

1: Program language selection, if the cost can be accepted, technology is OK, as far as possible do not choose ASP language, relative, PHP,. NET and other languages are more secure than ASP.

2: Close the site's directory browsing function, otherwise it is easy to expose your site A directory of files, these files may make malicious people have the opportunity.

3: Backend link access, do not write on the page, but also try not to use the admin, manage and other easy to guess the background directory name.

4: Backstage password aspect, I know some programmer friend, the site delivers to the customer when use, the backstage account is admin, the password is also admin or 123456, we avoid this kind of situation.

5: If you have administrative privileges on the server, you should periodically analyze the log files of the server (this is important, do not ignore), I before a server in the expiration of the previous day, the password was cracked, the server was hacked, and then look at the log when only found a hacker using software in the constantly poor lift my server password ...

6: Often modify the server password (letter + number + some symbols)

7: If your site is to use open source program to do, but also often pay attention to this open source program website, whether there is a new patch out, to be updated in time.

8: The last point, I feel is back up, even if we think we have done the perfect, but your security is never absolute, citing a top foreign hacker saying: Give me a network cable and a computer, I can handle the Pentagon!

So timely backups are critical.

Yes, still have to wordy a sentence, if you are developed with ASP, then backstage login procedures, remember to add

Pwd=replace (Replace (Request.Form ("password"), "'", ""), "or", "")

Uid=replace (Request.Form ("account Number"), "<>", "" "

Why? Because there is a so-called universal password, the above statement can filter out this situation. In short, do not wait until the site is black to pay attention to security.
