The acronym SSID is usually found in environments that have a Wi-Fi connection. See below, what is the SSID of the network and understand how it works. There are interesting ways to use the network function when setting up a wireless connection. Usage ranges from preventing access to sensitive business information to preventing connections to an unknown network.
The SSID — Service Set Identifier — of a Wi-Fi network is the technical term for its network name. For example, if there is a sign saying to connect to a network with an SSID of “Airport WiFi”, you just need to open the list of nearby wireless networks and join the network with the same name.
In a standard wireless network, a “set of services” refers to a collection of wireless devices with the same parameters. Therefore, the SSID is the identifier (name) that tells which set of services (or network) to join.
SSIDs are designed to be a unique name and differentiate multiple Wi-Fi networks in the same area so you can connect to the correct network. They are used by all types of Wi-Fi hotspots, including public Wi-Fi networks and home networks.
Router manufacturers usually provide a default SSID like “Linksys” or “Netgear”, but you can change it to whatever you want — having administrative access to the Wi-Fi network.
Usage tips for SSIDs
Security for business
Users can assign more than one SSID to an access point. Using multiple SSIDs allows users to access different networks, each with different policies and roles, increasing infrastructure flexibility and efficiency.
A good example is a restaurant owner setting up a network for customers and a network for employees. The two networks could use the same physical infrastructure but would have two different SSIDs, which would help prevent customers from being able to access sensitive information contained on the restaurant’s servers, such as billing sheets, vendors, etc.
Protection of home networks
- If a network doesn’t have wireless security options enabled — particularly password — anyone can connect to it knowing only the SSID;
- Using a default SSID increases the possibility that another network nearby has the same name, confusing wireless devices. When it discovers two networks with the same name, it can automatically connect to the one with a stronger signal, which can be an unsafe choice;
- The SSID chosen for a home network should only contain generic information. Some names unnecessarily trick hackers into attacking some networks at the expense of others.
