Securing Wireless Networks
This playbook outlines the steps necessary to secure a wireless network. It includes measures to protect against eavesdropping and unauthorized access, ensuring a safe and private wireless communication environment.
Step 1: Change Defaults
Modify the default admin username and password of the wireless router to prevent unauthorized access.
Step 2: Enable Encryption
Enable the highest level of encryption available (e.g., WPA3) on the wireless network to protect the data being transmitted over the air.
Step 3: SSID Management
Change the Service Set Identifier (SSID) to a unique name that does not reveal the brand or model of the router, and disable SSID broadcasting to make the network less visible.
Step 4: Filter MAC Addresses
Implement a MAC address filtering system to allow only recognized devices to connect to the wireless network.
Step 5: Update Firmware
Regularly check and update the router's firmware to patch known vulnerabilities and improve security features.
Step 6: Disable WPS
Turn off Wi-Fi Protected Setup (WPS) as it can be a security vulnerability due to certain flaws in its design.
Step 7: Disable Remote Access
Disable remote access to the router's settings to ensure that configuration changes can only be made from a connection to the network itself, not from the internet at large.
Step 8: Regular Audits
Conduct regular security audits to check for any unauthorized devices on the network and to ensure security features remain properly configured.
General Notes
Network Security
Securing a wireless network requires ongoing vigilance as new vulnerabilities can emerge. Regular updates and revisiting these security practices is recommended.
Backup Settings
Before making changes to the router settings, ensure you backup the current configuration to expedite recovery in case of any misconfiguration.
