I have had two WordPress blogs hacked into in the past. That was at a time when I was doing very little internet marketing, and until I found time to address the situation (months later), these sites were penalised in the search engines. They were not removed, but the rankings were reduced.
I back up my blogs using a plugin WP DB Backup. If anything happens I will restore my blog to the settings. I use my blog to be scanned by WP Security Scan plugin that is free regularly and suspicious-looking asks to be blocked by WordPress Firewall to fix malware problem.
Everything you've worked for will go check with it should the server of your site go down. You'll make no sales, get signups or no visitors to your website, until you get the site back up 32, and in short, you're out of business.
There's a section of config-sample.php that's headed"Authentication Unique Keys." There are four definitions that appear within the block. A hyperlink is within that part of code. You want to enter that link into your browser, copy the contents my review here that you get back, and then replace the keys you have with the unique, pseudo-random keys provided by the website. This makes it harder for attackers to automatically create a"logged-in" cookie for your site.
Install the WordPress Firewall Plugin. Prevent and this plugin investigates web requests with WordPress-specific heuristics that are easy to identify attacks.
Of course you can install more plugins to make your store more user friendly like share buttons or automatic backup plugin. That's all. Your store is now up and running!
