The main topic we’re going to discuss in this Episode 8 of Ask Paulie Anything, something you’ve probably heard of but you still don’t know much about, is “Renaming WordPress Database Prefix in the matter of security”.
I’m also going to answer the following questions:
- What is the WordPress Database Prefix?
- Is renaming the WordPress Database Prefix good security practice?
- Will Shield support renaming the WordPress Database Prefix?
- Does changing WordPress Database Prefix increase your security?
- Does Shield modify core WordPress files? Is that a good practice?
[0:26] – What Is The WordPress Database Prefix?
What I’m referring to is, there is the setting within the WordPress config file referring to the prefix that the database tables should use when WordPress creates tables. There are a lot of reasons for having this, but basically, all WordPress tables in the WordPress Database are prefixed with this set of letters.
This helps separate those tables as belonging to a particular WordPress installation.
There has been a lot of talk, for a long time, about renaming the prefix from the default which is wp_ as a security measure.
[1:00] – Is Renaming The Prefix Good Security Practice?
There are still plugins, and many people who like to think that renaming the db prefix is good security practice. But, there’s nothing secure about renaming the WordPress prefix. Nothing.
Because, if someone’s already attacked your website and gained the access, a very simple SQL query will that tell them what your Prefix is.
Once they’re inside, they’ll know what the prefix is. So, there’s no point changing it.
The point is:
Changing your WordPress Database Prefix does nothing to secure your website whatsoever.
[1:31] – Will Shield Support Renaming The WordPress Database Prefix?
Shield will not be including renaming the WordPress database Prefix functionality because there’s absolutely no reason to do so.
But isn’t it a little bit like “security through obscurity”?
Yes, but that’s not really security.
“Security through obscurity” helps to slow things down and just makes things a little bit more frustrating for the attacker.
It doesn’t secure your website and should not be relied upon as a security mechanism.
Does changing WordPress Database Prefix increase your security?
No, it doesn’t.
In fact, it’ll likely cause you problems, especially if it’s done via a WordPress plugin because the plugin needs the WordPress to load.
If the WordPress plugin is, in a given page load,
- attempting to rename the prefix
- change your WordPress config file
- rename on your tables
and it runs into any sort of trouble whatsoever, your website is likely going to be “toasted” (unless you know what you’re doing to revert it).
That gets me back to another point.
[2:23] – Does Shield Modify Core WordPress Files? Is That A Good Practice?
From the moment we’ve released Shield Security, our main principle was to never modify any core files, or any core WordPress hosting files. That includes the .htaccess and wp-config files.
Because, as I said, for WordPress plugins to change those, they require a valid WordPress load to work.
If there’re changes in the .htaccess or in the wp-config file that breaks your WordPress, the security plugin, can’t then revert those changes itself. It can’t fix any mistakes that are made, because WordPress itself can’t load.
Shield does not modify any WordPress core files and it certainly does not add or modify the php.ini files, which some security plugins do.
Generally, there are far too many WordPress plugins, especially security plugins, that leave their crap lying around your website when you uninstall and remove the plugin.
Shield doesn’t do any of that.
So, back to the point:
Be careful when you hear what people’re say is good security practice.
Just because 1 plugin does 1 thing, it doesn’t mean that:
a) it’s good security practice; and
b) that all other security plugins (including Shield) should have to do that to make it a good security plugin.
We choose our functionality very carefully.
