According to https://wpwhitesecurity.com, a survey of 40,000+ WordPress websites in the Alexa Top 1Million, more than 70% of WordPress installations are vulnerable to hacker attacks.
One of the quickest ways to protect your WordPress installation with StackPath is to restrict the wp-admin URL through a custom Path or IP address filter. A simple Edge Rule will accomplish this.
Blocking wp-admin access through your StackPath CDN URL
Use this section of the article if you are caching static assets. Please note that this will not block access to the wp-admin using your root domain.
- Log into the StackPath Control Panel
- Select Sites and then select Manage next to the site you wish to create the edge rule with
- Select CDN and choose EdgeRules
- Select Add New Rule and then + New Rule
- Match the Criteria and Features to this image
- Status Code = 403
- Conditional = "$request_uri = RegEx (Case Insensitive) = \/(wp-admin)\/.*
To test this Edge Rule please use the following two Curl examples. The results should match the examples below. Please replace "cdn.domain.com" with your WordPress installation url.
