Wi-Fi Network Security

This playbook describes the steps necessary to secure a wireless network. It includes actions to prevent unauthorized access and protect against various security threats.

Step 1: Access Control

Change the default username and password for the wireless router&#x27;s administrative interface to prevent unauthorized access to the router settings.

Step 2: Update Firmware

Regularly check for and install firmware updates for your router to ensure you have the latest security patches and features.

Step 3: Encrypt Traffic

Enable WPA2 or WPA3 encryption to secure the communication between connected devices and the router.

Step 4: Firewall Setup

Ensure that the router&#x27;s built-in firewall is enabled and properly configured to protect the network from external threats.

Step 5: Disable WPS

Turn off Wi-Fi Protected Setup (WPS) if it&#x27;s not needed, as it can be a security vulnerability.

Step 6: SSID Management

Change the default Service Set Identifier (SSID) and disable SSID broadcasting to make the network less visible to outsiders.

Step 7: MAC Filtering

Implement MAC address filtering to restrict network access to only known devices.

Step 8: Disable Remote Access

Turn off any remote management features on the router to prevent access from external networks.

Step 9: Secure Wi-Fi Guests

Create a separate guest network with its own password and restrict access to internal network resources.

Step 10: Physical Security

Place the router in a secure location where it is less likely to be tampered with by unauthorized individuals.


General Notes

Regular Audits

Conduct regular security audits of the network and connected devices to identify and fix vulnerabilities.

Education

Regularly educate users connected to the network about good security practices to prevent inadvertent compromises.
