If you have a WordPress blog or website, WordPress security must be an issue for you. I'm sure you must have heard about hackers attacking blogs and websites of other people. The damage done by them can be enormous, especially when the particular blog was high page ranked, displaying high in search engines and profitable. It is not the only type of websites attacked by hackers. The reasoning behind their acts can't be explained as logical. They will destroy it for fun. I know stories of people who one day, instead of their website saw a short note informing them that their website has been blocked by Google due to the thread it carries to other internet users. It was a result of hacker attack, who made changes to the website.
Finally, secure your wordpress site will tell you that there's not any htaccess in the directory. You can put a.htaccess file if you desire, and you can use it to control access from IP address to the directory or address range. Details of how to do that are available on the internet.
You can search for software that will backup your database and files. You can restore your site by means of your files and change everything that has to be changed, if hackers suddenly hack your site.
For me it's a WordPress plugin. They are drop dead simple to install, have all the features you need for a wikipedia reference job such as this, and are relatively cheap, especially when compared to having to hire someone to get this done for you.
Now we're getting into things. Whenever you install WordPress, you have to edit the file config-sample.php and rename it to config.php. You need to set up the database information there.
Just make sure that you may schedule, and you choose a plugin that's up to date with release and the version of WordPress, restore and clone.
