I back my blogs using a free plugin WP DB Backup up. I can always restore my website if anything happens. I use WP Security Scan plugin that is free to scan my site frequently and WordPress Firewall to block requests to secure your wordpress site.
I protect an access to important files on the site's server by putting an index.html file in the particular directory, that hides the files out of public view.
You should also place the"Anyone Can Register" in Settings/General to away, and you ought to internet have some type of spam plugin. Akismet is the old standby, the one I use, but there are lots of them these days.
All-Rounder security plug-ins can be go considered as a full security checker. They provide you with information about the weaknesses of the site and check and scan the site.
These are some. Fantastic thing is they don't need much time see here now to perform. These are simple solutions, which can be done easily.
