Question

What is the relationship between Bluetooth and Wi-Fi? What security challenges do Wi-Fi and Bluetooth technology present for a company?

Answer 1

`Hey,

Note: Brother if you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

Bluetooth and WiFi are different standards for wireless communication.

Bluetooth technology is useful when transferring information between two or more devices that are near each other when speed is not an issue, such as telephones, printers, modems and headsets. It is best suited to low-bandwidth applications like transferring sound data with telephones (i.e. with a Bluetooth headset) or byte data with hand-held computers (transferring files) or keyboard and mice.

Wi-Fi is better suited for operating full-scale networks because it enables a faster connection, better range from the base station, and better wireless security (if configured properly) than Bluetooth.

Cracking Attacks

Just like anything else using Passwords, there are desires and ways to crack those passwords to gain access. Without password attacks, there would be no Have I Been Pwned and other similar sites. Very much like other password attacks, there are the simplistic attacks (brute force) and the complex attacks. While brute force will eventually work, there are methods to minimize the impact if compromised.

Denial of Service

A Denial of Service (DoS) attack is more of a nuisance than a true technical attack. Think of it as an extreme brute force attack that overwhelms something, in this case, a Wi-Fi network or assets/nodes on it. My broad over generalization of it being a nuisance vice technical is an exaggeration; sometimes the vectors of attack for a DoS are very technical. Many technologies, namely web servers and websites, have DoS protective measures, as the internet can connect to them if they are public facing.

Malicious attackers can crash your devices, block them from receiving phone calls and drain your battery.

Bluetooth range is greater than you think

Bluetooth is designed to be a “personal area network.” That is to say: devices that are more than a few feet away should not be accessible via Bluetooth.

However, you’re not safe if you simply ensure there’s distance between you and a potential attacker; hackers have been known to use directional, high-gain antennas to communicate over much greater distances successfully.

Kindly revert for any queries
