When I was in college, one of my business instructors told us students that one of the biggest barriers to making money was procrastination.
I back up my blogs using a free plugin WP DB Backup. I can restore my website to the settings if anything happens. I use my blog to be scanned by WP Security Scan plugin that is free and WordPress Firewall to block requests that are suspicious-looking to fix wordpress malware plugin.

Oh . And incidentally, I was talking about plugins. Make sure it's a secure one, when you get a new plugin. Don't install any plugin just because the owner is saying on his website that plugin can allow you to do that or this. Maybe use a test blog to check the plugin, or maybe get a software engineer to examine it. This way is not a threat for you or your organization.
