WordPress.org

What does this thing actually do?

Lots of stuff - here's the list:

• Detect, intecept, and log suspicious-looking parameters — and prevent them compromising WordPress.
• Also protect most WordPress plugins from the same attacks.
• Optionally configure as the first plugin to load for maximum security.
• Respond with an innocuous-looking 404, or a home page redirect.
• Optionally send an email to you with a useful dump of information upon blocking a potential attack.
• Turn on or off directory traversal attack detection.
• Turn on or off SQL injection attack detection.
• Turn on or off WordPress-specific SQL injection attack detection.
• Turn on or off blocking executable file uploads.
• Turn on or off remote arbitrary code injection detection.
• Add whitelisted IPs.
• Add additional whitelisted pages and/or fields within such pages to allow above to get through when desirable.
