The WPScan Vulnerability Database finds out that more than 70% vulnerabilities happen due to out-of-date software. The most vulnerable versions of WordPress are all way back in WordPress version 3.X.

Lockdown WordPress in Case of an Emergency
Sometimes it’s a good idea to lockdown WordPress. When you know you are in a high risk of getting hacked, our WordPress Pros suggest that you should lockdown WordPress for a while.
One of the worst security vulnerabilities is backdoors. Backdoor vulnerabilities give hackers the ability to bypass security to obtain access to WordPress websites. Backdoor vulnerabilities can be exploited using – SFTP, FTP, wp-admin etc. According to Sucuri, 71% malware were backdoors out of all the hacking attempts in 2017.

wp-config.php file and add the following line after the opening
define( 'DISALLOW_FILE_EDIT', true);
2. Use Latest PHP Version
The most crucial WordPress site security factor is PHP. PHP is the spine of your WordPress site. It is vital and absolutely crucial that you use the latest version of PHP on your server. PHP 7.3 is the latest PHP version as of writing the article and we recommend using the latest PHP version always.
However, according to WordPress Stats, only a mere 0.3% users are using the latest version of PHP.
Every PHP version is usually supported for two years after its release. As of right now, PHP versions below 5.6 has no security support and are vulnerable to security threats. However, the stats show that more than 34% of people are still using PHP 5.2, which is kind of sad.

3. Check Existing Users in Your WordPress Dashboard
If you suspect that hackers have already logged into your WordPress system, go to Users>>All Users.
From the list, try finding if there’s any unknown users registered on your system. If you find out that are unfamiliar to you, delete those users ASAP.
Make sure there are no unfamiliar users on that list.
4. Use A Strong Password
One of the common WordPress security tips that you will find in every blog is using a strong and clever password. It’s okay if you use a memorable password on your social and email accounts but when you are managing your own website with Administrator privilege (Companion read: WordPress User Permissions, Explained), make sure you use a strong password.
Do not use a common password like “123456”, as revealed by Fortune’s most common passwords. Do not use “iloveyou” because that’s a common password too.
- You can use services like LastPass, Bitwarden (an open source alternative to LastPass), 1Password to generate a strong password with numerics, capital letter, small letter, and symbols. These password managers can also save your password behind a master password for your convenience.

“the one problem I (and many others have) with the logitech brio which I would like to add is that every time you reset your camera/PC all your personal camera settings (gain,exposure/white balance) resets itself.
