Setting up a secure wireless network is essential to protect users and devices from eavesdropping, unauthorized access, and cyberattacks. Below are the core configuration steps and technologies that enhance wireless security.
1. Changing the Service Set Identifier (SSID)
What is an SSID?
- The SSID (Service Set Identifier) is the public name assigned to a Wi-Fi network.
- It is broadcast by routers and access points so users and devices can find and connect to the network.
- SSIDs can be up to 32 characters long and usually appear in the list of available networks.
Security Risk of Default SSIDs
- Default SSIDs like “NETGEAR,” “Linksys,” or “TP-LINK” reveal the router’s brand and sometimes model.
- Attackers use this information to find known vulnerabilities or default credentials linked to those devices.
