To enhance the security of your WordPress site and minimize the risk of attacks, you can set your file and directory permissions to be as restrictive as possible, only granting write permissions when necessary. Here’s how you can configure your WordPress folder structure to be secure:
Step-by-Step Guide
1.
Restrict File and Directory Permissions
Set the default permissions for files and directories to be read-only.
# Navigate to your WordPress directory
cd /path/to/wordpress
# Set file permissions to 644 (readable by everyone, writable by owner)
find . -type f -exec chmod 644 {} \;
# Set directory permissions to 755 (readable and executable by everyone, writable by owner)
find . -type d -exec chmod 755 {} \;
# Secure wp-config.php further
chmod 400 wp-config.php
2.
Set Proper Ownership
Ensure the web server can read files but not write to them by default.
# Change ownership to your user and the web server group (e.g., www-data for Apache)
chown -R youruser:www-data /path/to/wordpress
3.
Configure the `wp-content` Directory
Only `wp-content/uploads` should be writable by the web server for media uploads. The rest of the directories should remain read-only.
# Make wp-content/uploads writable by the web server
chmod 755 wp-content
chmod -R 755 wp-content/*
chmod -R 775 wp-content/uploads
4.
Automated Updates
For WordPress to update itself, plugins, or themes, you can temporarily set writable permissions when necessary and then revert them. Alternatively, you can handle updates manually via FTP/SFTP or command line.
Automation Script
You can create a script to automate the process of setting and resetting permissions for updates:
# Function to set permissions for updates
enable_updates() {
echo "Enabling writable permissions for updates..."
chmod -R 775 wp-content
}
# Function to set secure permissions after updates
secure_permissions() {
echo "Setting secure permissions..."
find . -type f -exec chmod 644 {} \;
find . -type d -exec chmod 755 {} \;
chmod 400 wp-config.php
chmod -R 755 wp-content
chmod -R 775 wp-content/uploads
}
case "$1" in
enable)
enable_updates
;;
secure)
secure_permissions
;;
*)
echo "Usage: $0 {enable|secure}"
exit 1
;;
esac
Using the Script
1.
Create the Script
Save the script as `manage_permissions.sh` and make it executable.
chmod +x manage_permissions.sh
2.
Enable Permissions for Updates
Run the script with the `enable` option before performing updates.
./manage_permissions.sh enable
3.
Secure Permissions After Updates
Run the script with the `secure` option after completing updates.
./manage_permissions.sh secure
Final Recommendations
Regular Backups: Ensure you have regular backups of your site and database.
Security Plugins: Use reputable security plugins such as Wordfence or Sucuri to monitor and protect your site.
Keep WordPress Updated: Regularly update WordPress, themes, and plugins to the latest versions.
File Integrity Monitoring: Implement file integrity monitoring to detect unauthorized changes to your files.
By following these steps, you can enhance the security of your WordPress site by minimizing write permissions and only allowing them when absolutely necessary.
