An SSID, or Service Set Identifier, is the name assigned to a wireless network. It is used to identify the network to devices that want to connect to it. When you scan for available Wi-Fi networks, the SSIDs of those networks are displayed, allowing users to select the one they wish to join.
### How to Know if a Network is Locked
You can often tell if a network is locked (i.e., secured with a password) by the presence of a padlock icon next to its SSID when scanning for Wi-Fi networks on your device. Additionally, if you attempt to connect to a secured network, you will be prompted to enter a password. In contrast, open networks will allow you to connect without any credentials.
### Drawback of “Hiding” Your SSID
Hiding your SSID can give a false sense of security. While it may reduce casual attempts to connect to your network, it does not provide actual protection against determined attackers. Skilled users can easily discover hidden networks using tools that scan for network traffic. Additionally, hiding the SSID can make it more inconvenient for legitimate users to connect, particularly if they don't know the network name.
### Broadcasting vs. Hiding Your SSID
In general, it is often considered a better choice to **broadcast your SSID** for a few key reasons:
1. **Convenience**: Broadcasting the SSID makes it easier for authorized users to find and connect to the network without needing specific instructions to enter the SSID manually.
2. **False Security**: Hiding the SSID does not provide true security. Network security should primarily rely on strong encryption methods (like WPA3) and complex, unique passwords rather than obscuring the SSID.
3. **User Experience**: When troubleshooting or assisting users in connecting, having a visible SSID simplifies that process, reducing confusion.
Therefore, broadcasting the SSID, combined with proper security measures like strong passwords and encryption, is usually the best approach to securing a wireless network.
