WordPress Forms Security Best Practices [Security Guide]

Secure Online Forms

WordPress forms security is probably the most essential component of any web application system. If an application cannot even secure the data it collects, everything else it does is pretty much useless anyway. Today we are going to talk about why security is essential in the context of web forms and how we can create highly secure online forms on a WordPress website.

You must have interacted with a lot of online forms by now. Whether it is for contact requests, registering for an event, or probably just signing up for a newsletter service. When working with any of these, you must have just entered your details and submitted the form. Right? But how you be really sure that your data on the site will remain secure? The problem of WordPress forms security is so widespread that Google took notice of it in 2017 and started displaying such forms as insecure to users, through its Chrome web browser.

 

WordPress Forms Security

WordPress, being the most popular platform for building websites, isn’t safe from this scourge. One such major vulnerability was detected in the Ninja Forms plugin in 2016. And Ninja Forms is currently installed on more than a million WordPress websites.

So, what can a WordPress site owner do to secure online forms and to keep user information safe from prying eyes? Well, the answer is RegistrationMagic. It is the fastest growing user registration plugin available for WordPress and offers exceptional WordPress forms security features to keep form submissions safe.

Here’s a quick look at the security features RegistrationMagic offers…

1. reCaptcha

RegistrationMagic provides seamless integration of its online forms with Google’s reCaptcha user authentication check. reCaptcha for RegistrationMagic forms can be activated from RegistrationMagic’s Global Security Settings.

All you need to do is enable the reCaptcha setting there and add your Site Key and Secret Key. Both of which can be obtained from Google’s reCaptcha Portal. Once activated, it’ll setup the reCaptcha authentication on all your RegistrationMagic forms.

2. Form Submission Limit for a Device

Hackers are increasing employing brute force techniques to find flaws in a form’s security and exploit it. However, this a trial and error method and requires plenty of failed attempts before any success is achieved.

RegistrationMagic halts such brute force attacks halfway by giving you the power to limit form submissions from a particular device. This means that if a hacker is trying to find security flaws in the website from the form, RegistrationMagic will stop any further submissions from his/her device. This will end the possibility of any further attacks from it.

3. Password Rules

Enabling password rules is a highly effective way to make sure users registering from your form aren’t putting in weak passwords. Weak passwords can easily be targeted by hackers to gain access to your website and then wreak havoc once inside. Always ensure that user accounts on your website have limited access and are not using weak passwords.

Following are the key rules that passwords should follow to be considered strong…

  1. At least one uppercase letter
  2. At least one number
  3. Contain at least one special character
  4. Minimum length (should be at least 7 letters long)
  5. Maximum length (15 is a good max limit but the more the better)

Password Rules

4. Ban IP Addresses

If you received a lot of redundant form submissions from a particular IP address, it is always a good idea to ban that IP address from accessing the form again. You never know if those redundant form submissions were spam or someone just trying to break into your website. In most cases, it is the latter.

5. Ban Email Addresses

Similar to banning IP addresses, you can also ban email addresses from accessing the form too. To make the form stronger in resisting any possible attacks, use both the bans simultaneously.

6. Blacklisted/Reserved Usernames

Common usernames are easy pickings for hackers. Before getting to the password of a user account, a hacker has to determine the username of the account first. However, if someone is using common usernames like ‘admin’ or ‘company’, that person has done half of the hacker’s work then and there. The hacker now only has to determine the password for the account as the username is already on their list to go for first. So, always reserve common usernames from being used on your website.

Make use of RegistrationMagic and follow these simple WordPress forms security rules to secure online forms and to keep hackers away from your web forms for good.
