Last year and a half taught us that WordPress security shouldn't be taken lightly by any means. Between 15% and 20% of the planet's high traffic sites are powered by WordPress. The fact that it is an Open Source platform and everyone has access to its Source Code makes it a prey for hackers.
Install the fix hacked wordpress database Firewall Plugin. Quit and this plugin investigates net requests to recognize obvious attacks.
Is also important. You want to backup all the files and database you can easily bring your blog back like nothing.
You also need check here to place the"Anyone Can Register" in Settings/General to away, and you should have some type of spam plugin. Akismet is the one I use, the old standby, but there are lots of them nowadays.
Security plug-ins can be considered as a security checker. They give you information about the weaknesses of the site and check and scan the entire website.
I prefer using a WordPress plugin to get the work done. Just make sure the plugin you choose is in a position to do backups that are select, has restore and can replicate. Also be sure it is frequently updated to keep pace with all versions of WordPress. There is not any use in not functioning, and backing your data up to a plugin that's out of date.
