Wireless Best Practice

Wireless protocols such as Wi-Fi, Bluetooth, and NFC are susceptible to a number of weaknesses and vulnerabilities. One common weakness is the potential for interception of wireless signals by unauthorized parties. This can be done using various techniques such as packet sniffing, which involves using specialized software to monitor and analyze wireless traffic. This can allow attackers to gain access to sensitive information such as login credentials and other sensitive data.

Another weakness of wireless protocols is the potential for denial of service attacks, where an attacker floods a wireless network with traffic, effectively blocking legitimate users from accessing it. In some cases, this can be done using relatively simple tools, such as a powerful wireless antenna or a device that generates a large number of fake authentication requests.

Additionally, many wireless protocols are not designed with security as a primary concern, which can make them vulnerable to a wide range of attacks. For example, some older versions of the Wi-Fi protocol used relatively weak encryption algorithms, which made it relatively easy for attackers to intercept and decode wireless traffic.

Overall, while wireless protocols such as Wi-Fi, Bluetooth, and NFC are convenient and widely used, they do have significant weaknesses and vulnerabilities that need to be taken into account when considering their use. It is important to regularly update your wireless devices and to use strong, unique passwords to protect your network and keep your data safe.

If you don’t explicitly need it, or use it, turn it off!

Unfortunately NFC cannot be turned off on most smart devices today, because of design, and lack of software controls.
