Do you need a firewalls to configure a safe and secure wireless? The short answer is "Yes." Firewalls are commonly used to protect private networks that are connected to the internet. Without a firewall, hacker's, malware, and other unauthorized traffic can just come in a steal your personal information right off your computer. Professor Messer has great videos explaining the importance of a firewall and how it works in the link below. Are bluetooth connections more or less secure then wireless? Eavesdropping on bluetooth is definitely possible but also difficult because it implements authentication and key derivation with custom algorithms based on the SAFER+ block cipher, and it uses the E0 stream cipher for encrypting packets. If you understood any of that, it just means bluetooth communication is encrypted. Bluetooth was developed with built in security and is one of the most secure protocols for mobile device communication but is still vulnerable to attacks. Common attacks on bluetooth are Bluejacking, Bluesnarfing and bluebugging. To protect a prevent attacks just simply disable your bluetooth or turn off discovery mode if bluetooth is used on a mobile device. I attached some fact sheet below about wireless attack facts. RFID is almost everywhere. It can be in an access badges, store inventory, pets or anything that needs to be tracked. RFID chips are very small so its easy to put wherever we need it. Unlike bluetooth, some RFID do not have a power source and receives it power from radio signals while others do have a dedicated power source. Technology that was built on RFID is Near Field Communication which allow short range communication within 2 inches of a devices. Compared to bluetooth RFID and NFC are very slow but consume much less power than bluetooth.
