A home network can be wired (using Ethernet cables) or wireless (using Wi-Fi). It may also be a mixture of the two, with some devices connecting with Ethernet and others connecting wirelessly. Wireless is generally more convenient; however, you’ll need to think about wireless security. Below are some important security terms you’ll need to know.
SSID: A service set identifier, commonly called the SSID, is the name of a wireless network. You should change the default SSID to something unique that you’ll remember. You may not want to use your actual name, but you can use a hobby or other interest (like swimming1).
Encryption password: An encryption password is a series of characters that is used to control access to the network. For even greater security, some people use a passphrase, which is longer—and therefore more secure—than a password. You should choose a password or passphrase that’s easy for you to remember but difficult for others to guess.
Encryption: Encryption prevents unauthorized users from reading data that is transmitted over your wireless network. The data is coded into an unreadable form, and it can only be decoded by a computer that has the correct password or passphrase. The most common types of encryption for wireless networks are WPA (Wi-Fi protected access) and WPA2.
Although it’s possible to create a wireless network that doesn’t have a password, it is very risky. You should always create a password or passphrase to protect it from unauthorized access.
