Wireless network security definition
Wireless network security refers to the protection of wireless networks, devices, and data from unauthorized access, theft, or damage. Wireless networks transmit data through radio waves, making it more susceptible to interception by unauthorized users who are within range of the network. Hackers can use special software to intercept and decode the data sent over Wi-Fi to steal sensitive information. This poses a risk both for users’ private information (like credit card details, home addresses, Social Security numbers) and corporate data (financial information, customer lists, product designs).
Wireless network security methods
- Encryption. This involves encoding data transmitted over the network to prevent unauthorized access. The Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), and Wi-Fi Protected Access II (WPA2) protocols are all used to secure wireless networks.
- Authentication. Using passwords, usernames, and biometric authentication to ensure that only authorized users can access the network.
- Firewalls. Using a software or hardware-based security system to monitor and control incoming and outgoing network traffic.
- Physical security. Securing the physical components of the wireless network (routers, access points, and other devices), so that no one can access and tamper with them.
- Additional software. End users can use virtual private networks, like NordVPN, to secure their data traveling through the wireless network even further with an additional layer of encryption.
