-
Use Strong Encryption Protocols
-
Implement WPA3 (Wi-Fi Protected Access 3) or at least WPA2 for encrypting data.
-
Avoid using outdated protocols like WEP, which are easily cracked.
-
-
Enable Network Authentication
-
Use password-based authentication to prevent unauthorized access.
-
Consider 802.1X authentication for enterprise environments with centralized access control.
-
-
Change Default Settings
-
Change default SSID (network name) and administrative passwords on routers and access points.
-
Disable broadcasting SSID if extra obscurity is desired (though not a strong security measure).
-
-
Use MAC Address Filtering
- Restrict network access to specific devices by allowing only known MAC addresses.
-
Enable Firewall and Intrusion Detection
-
Use built-in router firewalls or dedicated security appliances.
-
Monitor for unusual activity or unauthorized connection attempts.
-
-
Regularly Update Firmware and Software
- Keep wireless devices’ firmware and software up to date to patch vulnerabilities.
-
Disable Unused Services
- Turn off WPS (Wi-Fi Protected Setup) and other unnecessary features that may introduce security risks.
-
Implement Network Segmentation
- Separate guest networks from private networks to limit access scope.
-
Use VPNs for Sensitive Communication
- Encrypt data traffic over wireless networks by using Virtual Private Networks (VPNs).
-
Physical Security
- Secure the physical access points to prevent tampering or unauthorized access.
