Wireless Security

    With a wireless network, your information is traveling through the airwaves, not physical wires, so anyone within range can "listen in" on your network. Below are some of the encryption standards used in wireless networks.

     

      Advantages Disadvantages
    No Encryption Easy to connect No Security
    Vulnerable to security hacks
    WEP (Wireless Equvalency Privacy) Available on all wireless network adapters
    Provides basic security through a single password
    Speed
    WPA (Wifi Protected-Access) Highest level of security using dynamic key encryption.
    Uses TKIP (Temporal Key Integrity Protocol) for encryption of data
    Not supported in older wireless network cards.
    WPA2 (Wifi Protected-Access) Second generation of WPA.
    Backwards compatible with WPA.
    Uses AES (Advanced Encrypted Standard) for encryption of data.
    Not supported in older wireless network cards.
