2. Schedule Regular Scans and Monitor Core Files

Keeping your WordPress site secure requires regular security scans and monitoring of your core files. This helps detect and prevent potential threats.

Scheduling Scans

Use plugins like Wordfence or MalCare to schedule regular security scans. These plugins can:

Detect malicious activities like SQL injections and cross-site scripting (XSS) attacks
Block these threats
Provide detailed reports on any security issues found

This allows you to take prompt action to resolve any issues.

Monitoring Core Files

It’s crucial to monitor your WordPress core files for unauthorized changes. Plugins like Wordfence can:

3. Set Up Real-Time Blocking and Notifications

Protecting your WordPress site requires real-time monitoring and alerts. Here’s how to configure real-time blocking and notification settings:

Real-Time Blocking

Real-time blocking stops malicious traffic as it happens. Set up your firewall to:

Detect and block known attack patterns like SQL injections and cross-site scripting (XSS)
Block traffic from suspicious IP addresses or locations

Plugins like Wordfence and NinjaFirewall offer real-time blocking features.

Notification Settings

Stay informed about potential threats by setting up notifications. Configure your firewall to notify you when:

4. Optimize Firewall Sensitivity Settings

Adjusting your firewall’s sensitivity settings is key to ensuring it effectively blocks malicious traffic without interfering with legitimate requests. Here are some important considerations:

Firewall Block Response

Set up your firewall to respond appropriately when it detects malicious data. This includes specifying how to handle blocked traffic, such as:

Displaying a custom error message
Redirecting users to a safe page

Firewall White Listing and Ignore Options

Use white listing and ignore options sparingly to bypass firewall checks for specific factors. However, be cautious when doing so, as this can create security vulnerabilities if not done correctly.

Firewall Blocking Options

Customize your firewall’s blocking options to suit your website’s needs. This includes configuring settings for:

Blocking Option	Description
Directory Traversals	Prevent unauthorized access to files and directories.
SQL Queries	Block potential SQL injection attacks.

5. Whitelist and Blacklist IP Addresses

Managing IP addresses is crucial for controlling who can access your WordPress site. Whitelisting allows trusted IP addresses to interact with your site without restrictions, while blacklisting blocks malicious IP addresses from accessing your site.

IP Address Management

To whitelist an IP address, you can use a plugin like MalCare or edit your .htaccess file. Here’s how to whitelist an IP address in .htaccess:

order deny,allow
deny from all
allow from YOUR_IP_ADDRESS

Replace YOUR_IP_ADDRESS with the IP address you want to whitelist. Separate multiple IP addresses with a space.

To blacklist an IP address, you can use a plugin or edit your .htaccess file. Here’s how to blacklist an IP address in .htaccess:

order deny,allow
deny from IP_ADDRESS_TO_BLOCK
allow from all

Replace IP_ADDRESS_TO_BLOCK with the IP address you want to block.

Action	Description
Whitelist IP	Allow trusted IP addresses to access your site without restrictions.
Blacklist IP	Block malicious IP addresses from accessing your site.

Whitelisting and blacklisting IP addresses help you control access to your WordPress site, enhancing its security.

6. Utilize Country Blocking for Enhanced Security

Country blocking allows you to restrict access to your website based on geographical location. This feature is useful for preventing malicious traffic from countries known for cybercrime activities.

Configuring Country Blocking

To set up country blocking, access your WordPress firewall plugin’s settings. The process may vary depending on the plugin you’re using. For example, with MalCare, you can:

Go to the Sites screen
Select the site you want to modify
Click the Globe Icon to open the GeoBlocking screen
Select the countries you want to block

Benefits of Country Blocking

Country blocking offers several advantages:

Improved security: By blocking traffic from countries associated with cybercrime, you reduce the risk of unauthorized access and malicious activities on your website.
Better performance: Blocking unwanted traffic can reduce server load and improve your website’s overall performance.
Compliance: Country blocking can help you comply with regulations that require restricting access based on geographical location.
