I back my blogs frequently using a plugin WP DB Backup up. I can restore my website to the 13, if anything happens. I use my site to be scanned by WP Security Scan plugin that is free and WordPress Firewall to block suspicious-looking asks to fix wordpress malware plugin.
Should the server of your site go down, everything you have worked for will proceed with it. You will make no sales, get no traffic or signups to your site, until you get the site back up again and in short, you are out of business.
For me it's a WordPress plugin. They're drop dead simple to install, have all the features you need for a job like this, and are relatively inexpensive, especially when compared to having to hire someone to have this done for you.
Whitelists phrases and black based on which field they look within. (unknown/numeric parameters vs. known post bodies, comment bodies, etc.).
You don't always think about needing security, Whenever your site is new but you do get redirected here have to protect yourself and your investment. Having a site go down and not being able to restore it quickly may mean a big loss of consumers who can't find you and won't remember to look for your site again later. Don't let that happen to you. Back your site up as soon as you get it started, as the site is operational, and schedule backups for as long. This way, you will have peace and WordPress security of mind.
