There are countless blogs. Money is being made by some of us through it and some don't. Most of the bloggers use WordPress at the moment. You need to be sure that your blog is secure.
In my opinion, the best way to make sure that your WordPress security is via the use of a fix wordpress malware virus backup plugin. This is a relatively inexpensive, elegant and easy to use way to be sure your site is accessible to you in case of a disaster.
I might find it somewhat harder to crack your password if you're one of the ones that are proactive. But if you're among those responsive ones, I might get you.
Should you ever want to migrate your site elsewhere, such as a new web host, you'd be able to pull this off without a blog hitch, and also without having to disturb your old site until the new one was set up and ready to roll.
You can make a firewall that blocks hackers from infiltrating your blogs. The hacker is prevented by the firewall from coming into your files. You must also have updated version of Apache. Upgrade your PHP also. It is important that your system is filled with upgrades.
Do your homework and some hunting, but if you are pressed for time and want to get this try out the WordPress safety plugin that I use. It's a relief to know that my site (and business!) are secure.
