Network Security Key is the password or code needed to access a local area network. Most of us are familiar with network security keys at home, you use one to join your personal Wi-Fi network. Network security keys allow users to establish a secure connection and prevent unauthorized access to the network.
For example, diners who wish to visit a website using a restaurant’s local network would likely have to connect using the security key of that particular network. This may include entering a specific password to access the key, which the users’ devices can remember each time they try to log in to that network. Network security key offers protection from a range of cyber threats like the following;
a. Piggybacking:-
It occurs when a user connects to an unprotected or a poorly protected wireless network in close range, such as a neighbor’s Wi-Fi network. That neighbor could have the ability to access and compromise the initial user’s information, or potentially attack the network itself.
b. Wardriving:-
It is a more targeted version of piggybacking in which hackers single out unprotected or poorly protected Wi-Fi networks in close range.
c. Evil Twin Attack:-
It entails a false network that closely resembles a legitimate one — for example, a Wi-Fi network similar to that of a coffee shop’s, which appears to have the same security protocols and that dupes users into believing that they have connected to the coffee shop’s actual network. Those users could then easily have their data compromised.
d. Wireless Sniffing and Unauthorized Computer Access:-
These occur when individuals seek out poorly or unprotected networks and are able to access and compromise sensitive data communicated through and within them, such as credit card numbers provided for online transactions or personal files on a digital device.
e. Shoulder Surfing:-
It is less sophisticated than other digital risks but just as dangerous. It occurs when an individual observes the information another user is inputting into a computer or mobile device. For the user at a coffee shop, a shoulder surfer could figure out a network password or personal information, such as a Social Security number or home address, simply by watching the information typed into the device.
