Overview of NGINX Access Control

NGINX Access Control is a feature in the server. It manages who can view certain content on your site.

NGINX access control works through the ngx_http_access_module. It evaluates allow and deny orders to block HTTP requests. You can:

• Block traffic based on user IP

• Set up http basic authentication

• Use allow and deny orders to manage traffic flow.

This protects data and applies strong security measures. Using CloudPanel, you do not need to edit every file. This makes it easier to install proper access without risking a setup error.

CloudPanel allows you to host many websites on a single server. Every site has its setup. This helps avoid issues and simplifies management. It also works well with proxy rules and upstream servers. It supports various platforms, such as:

• WordPress

• Joomla

• Node.js

• Laravel

• Magento

Why NGINX Access Control Matters for CloudPanel Users?

1. Enhanced Security

CloudPanel comes with built-in tools like IP blocking, firewall settings, and site isolation. These keep admin panels and other private areas safe. You can allow only trusted IP addresses to access. These reduce brute-force attacks with NGINX.

They also manage unwanted traffic. This prevents damage before it can happen. You have full control over who gets in.

2. Simplified Management

There’s no need to dig through config files. CloudPanel offers a simple dashboard. You can manage access rules in a few steps. You can block traffic, add IP rules, or set up HTTP authentication.

This cuts your setup time from hours to minutes. It’s simple enough for beginners but powerful enough for experienced users. Everything you need is in one place.

3. Resource Protection

When you send too many requests to your server, it can slow down. CloudPanel allows you to set limits and block heavy traffic to specific paths. It keeps your server operating without issues, even during peak times or under attack.

If one site has a problem, the others stay protected. Each site functions on its own, which allows for uninterrupted functionality.

4. Compliance and Auditability

CloudPanel helps websites follow strict privacy laws, such as GDPR and HIPAA. It limits access by IP address, region through GeoIP, or password. CloudPanel does not handle user roles in a direct manner. It saves access attempts in NGINX logs.

5. Partnering with MGT.io for Enhanced Management

5 Steps to Configure IP and Authentication Access Control in CloudPanel

Step 1: Access the Security Section

• Start by logging into your CloudPanel Dashboard.

• On the left-hand menu, navigate to Admin > Security to open access settings.

Step 2: Block or Allow IP Addresses

• In the CloudPanel Dashboard, navigate to Security > Firewall.

• Click the "Add IP" button.

• Enter the IP address in IPv4 or IPv6 format. For instance:

  1. `8.8.8.8`

  2. `2400:6180: 100 :d0::99b:5001`

• Select whether to block/allow the IP address.

• Click Save.

• CloudPanel creates an NGINX to permit a trusted IP for a specific site.

• It's in the site’s configuration file in `/etc/nginx/sites-available/`):

  location / {

  allow 8.8.8.8;

  deny all;

  }

• For sensitive facilities, such as SSH or CloudPanel, add allow rules. This is for trusted IPs in the Firewall section.

Step 3: Configure Firewall Rules (Optional)

• Go to Security Menu > Firewall section.

• Click Add Rule.

• Choose the protocol—usually TCP.

• Enter the port number, like:

  1. 22 for SSH

  2. 8443 for CloudPanel

• Add the IP addresses you want to permit.

• Set default policy to deny.

Step 4: Enable Basic Authentication

• Navigate to Security > Basic Auth.

• Turn on the switch to enable Basic Authentication for the desired site or path.

• Add a username and a strong password.

• Click Save.

• This configures NGINX to protect the specified area.

  location / {

  auth_basic "Restricted Area";

  auth_basic_user_file /etc/nginx/.htpasswd;

  }

• You can create this file with:

  htpasswd -c /etc/nginx/.htpasswd your_username

Step 5: Enable Basic Authentication

• Connect to your server via SSH.

• Run this command to enable Basic Authentication:

  sudo clpctl cloudpanel:enable:basic-auth --userName='yourusername' --password='yourpassword'

• This adds this NGINX code to your site’s configuration.

• Find it in /etc/nginx/sites-available/:

  location / {

  auth_basic "Restricted Area";
  
  auth_basic_user_file /etc/nginx/.htpasswd;
  

  }

• The .htpasswd file stores the credentials.

• To disable Basic Authentication, run:

  sudo clpctl cloudpanel:disable:basic-auth

• This is important for automation or remote management.

11 NGINX Access Control Best Practices to Protect Your Server

1. Restrict Access

Restrict access to sensitive areas. Only trusted IPs have permission. In CloudPanel’s Vhost Editor, add:

location /admin {

allow 192.168.1.0/24;

deny all;

}

This lets only the 192.168.1.0/24 network access the area.

2. Install Password Protection (Basic Authentication)

Protect pages or folders with a login prompt using Basic Authentication. In CloudPanel’s Security > Basic Auth. Set it up to add:

location /protected {

auth_basic "Secure Area";

auth_basic_user_file /etc/nginx/.htpasswd;

}

3. Integrate IP Whitelisting and Authentication

You do not have to choose one or the other. Use both for stronger protection. It allows you to choose:

• An approved IP address

• A password

• Both

This is a smart way to protect tools like dashboards or APIs. Integrate IP whitelisting and authentication for stronger protection. This allows you to require both an approved IP address and a password.

4. Limit Allowed HTTP Methods

Only let in the types of requests your site needs. For most pages, GET and HEAD are enough—block everything else. This helps reduce the risk of misuse through rare or unsafe request types.

5. Use Geographic Restrictions

If your support only targets certain regions, block traffic from the rest. With GeoIP, you can filter access based on country.

6. Enforce Secure SSL/TLS

Redirect HTTP traffic to HTTPS. This protects login information and other data. Secure your TLS settings. Encrypted traffic should be the default on every site you run.

7. Apply Rate Limiting

Limit the rate at which users can send requests to your server to prevent spam or overload. You can make up to 10 requests per second from a single IP address. Also, you can queue 20 more requests. This keeps your server stable.

8. Keep NGINX and Dependencies Updated

Outdated software leaves your server at risk. Ensure that NGINX and your packages are up to date. Patching known issues prevents problems.

9. Disable Unnecessary Information Disclosure

Turn off server_tokens to hide version details from responses. The less attackers know your setup, the harder it is for them to attack. It's a quick win for improving security.

10. Review and Audit Access Logs

Set aside time to review your logs. Watch for failed login attempts or unusual traffic patterns. Your logs are often the first place where trouble shows up.

11. Test Access Rules

Check your access control rules in a staging environment. You can confirm their correct functionality. It blocks unauthorized access while allowing traffic.

Use CloudPanel’s Vhost Editor to simulate different IP addresses or authentication scenarios.

8 Steps to Secure a Web Application with NGINX in CloudPanel

Step 1: Restrict Access with IP

• Limit access to sensitive facilities.

• In CloudPanel’s Security > Firewall section.

• Add rules to allow only specific IPs, such as office or VPN addresses

• For SSH, configure the server’s firewall.

• UFW or iptables to allow only VPN IPs:

  ufw allow from 192.168.1.0/24 to any port 22

Step 2: Enable Basic Authentication for Development

• Protect development and staging sites with a login prompt.

• In CloudPanel’s Security > Basic Auth.

• Enable authentication and set credentials.

• It adds to the NGINX configuration:

  location / {

  auth_basic "Staging Area";

  auth_basic_user_file /etc/nginx/.htpasswd;

  }

• Create the .htpasswd file:

  htpasswd -c /etc/nginx/.htpasswd dev_user

Step 3: Enhance Security

• Add 2FA to admin panels. It includes WordPress and Joomla. This is for stronger login security.

• In CloudPanel, install 2FA plugins:

  1. For WordPress:

• Go to Plugins > Add New.

• Search for Two-Factor

• Install and activate.

  2. For Joomla:

• Go to Extensions > Manage > Install.

• Add Google Authenticator.

• In the application’s user settings, enable 2FA.

• Scan the QR code with an authenticator app.

• For extra protection, configure NGINX Authentication.

• Go to CloudPanel’s Security > Basic Auth:

  location /wp-admin {

  auth_basic "Admin Login";

  auth_basic_user_file /etc/nginx/.htpasswd;

  }

• Create the .htpasswd file:

  htpasswd -c /etc/nginx/.htpasswd admin_user

• NGINX enforces a password prompt.

Step 4: Block Malicious IPs

• Use CloudPanel’s Security > Firewall to block IPs. For instance, block an IP after too many failed logins:

  location / {

  deny 203.0.113.10;
  

  }

• CloudPanel can integrate with tools like Fail2Ban. It can block IPs after failed login attempts. Install Fail2Ban:

  apt-get install fail2ban

• Configure it to monitor NGINX logs.

Step 5: Secure APIs

• Protect API endpoints by limiting requests.

• In CloudPanel’s Vhost Editor (Admin > Sites > Edit Site), add:

  limit_req_zone $binary_remote_addr zone=api_limit:10m rate=5r/s;

  location /api {

  limit_req zone=api_limit burst=10;
  

  }

• This limits APIs to 5 requests per second per IP. It comes with a queue for up to 10 extra requests.

Step 6: Enforce HTTPS with SSL Certificates

• Encrypts all traffic to protect sensitive data.

• In CloudPanel’s Security > SSL.

• Enable Let’s Encrypt for all sites. This adds to the NGINX configuration:

  server {

  listen 443 ssl;
  
  ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
  
  ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
  

  }

• Redirect HTTP to HTTPS:
  server {
  listen 80;
  return 301 https://$host$request_uri;
  }

Step 7: Monitor Access with NGINX Logging

• Track access attempts to identify security issues.

• In CloudPanel’s Vhost Editor, enable detailed logging:

  log_format main '$remote_addr - $ remote _ user [$ time _ local] "$request" $status';

  access_log /var/log/nginx/access.log main;

• Check logs for unauthorized attempts:

  grep "401" /var/log/nginx/access.log

• Store logs in a secure location.

Step 8: Maintain Security

• Update CloudPanel, NGINX, and hosted apps. It fixes vulnerabilities that may bypass access controls and weaken security.

• In CloudPanel, use the Updates section for new versions.

• Disable unused facilities in NGINX:

  server {

  listen 80;
  
  server_name unused.example.com;
  
  return 444;
  

  }

• Enforce strong passwords for all users via CloudPanel’s user management. It strengthens authentication-based access controls.
