Wireless Router Hardening

Wireless router hardening is the process of securing a wireless router to protect a network and its connected devices from unauthorized access and various cyber threats. This involves configuring the router’s settings and features to enhance security. Here are key steps and best practices for wireless router hardening:

1. Change Default Login Credentials

Admin Username and Password: Default usernames and passwords are easily guessable. Change them to strong, unique credentials.

2. Update Firmware Regularly

Firmware Updates: Router manufacturers release firmware updates that fix vulnerabilities and improve security. Ensure your router’s firmware is up-to-date.

3. Use Strong Encryption

Wi-Fi Encryption: Use the strongest available encryption for your Wi-Fi network, such as WPA3 or WPA2.
Disable WEP: Avoid outdated encryption methods like WEP, as they are easily hackable.

4. Secure Wi-Fi Network Name (SSID)

SSID Name: Change the default SSID to something unique that doesn’t give away personal or location information.
Disable SSID Broadcasting: Consider disabling SSID broadcasting to make your network less visible.

5. Enable Network Firewall

Firewall Protection: Most routers have built-in firewall features. Ensure they are enabled and properly configured.

6. Disable Remote Management

Remote Access: Turn off remote management features to prevent access to the router’s settings from outside your local network.

7. Use MAC Address Filtering

MAC Filtering: Restrict network access to known devices by allowing only specific MAC addresses.

8. Disable Features Not in Use

WPS (Wi-Fi Protected Setup): Disable WPS, as it can be a security risk.
UPnP (Universal Plug and Play): Disable UPnP unless it’s necessary for specific applications.

9. Separate Networks

Guest Network: Set up a separate network for guests with limited access to local network resources.
Segmentation: Consider segmenting your network to separate IoT devices from computers and smartphones.

10. Monitor Connected Devices

Device Monitoring: Regularly check for unknown devices connected to your network.

11. Secure Physical Access

Physical Security: Place the router in a secure location to prevent unauthorized physical access.

12. VPN (Virtual Private Network)

VPN Use: Consider using a VPN for secure remote access to your network.

13. Regular Security Audits

Audit and Update: Periodically review and update your security settings to ensure ongoing protection.

Wireless router hardening is an ongoing process, not a one-time setup. Regularly reviewing and updating security settings in response to new threats and vulnerabilities is crucial for maintaining a secure network.
