Measures and protocols designed to protect wireless networks from unauthorized access and threats.
Description
Wi-Fi Network Security refers to the various methods and protocols used to secure wireless local area networks (WLANs) from unauthorized access, data breaches, and cyberattacks. The importance of Wi-Fi security has grown significantly as more devices connect to the internet wirelessly, increasing the potential for security vulnerabilities. Key security protocols include WPA2 (Wi-Fi Protected Access 2) and the more recent WPA3, which use strong encryption to protect data transmitted over the air. Other measures involve setting strong passwords, using firewalls, and regularly updating router firmware to patch vulnerabilities. Implementing network segmentation and guest networks can also enhance security by limiting access to sensitive information. Businesses, in particular, must prioritize Wi-Fi security as breaches can lead to loss of customer trust and financial repercussions. Public Wi-Fi networks, such as those in cafes and airports, are especially at risk, making it essential for users to take extra precautions when connecting to these networks.
Examples
- WPA3 is the latest security protocol offering improved protection against brute force attacks, making it harder for hackers to guess passwords.
- A coffee shop using a separate guest network for customers can help protect its internal network from potential cyber threats.
Additional Information
- Regularly changing the Wi-Fi password can prevent unauthorized access to the network.
- Using a VPN (Virtual Private Network) while on public Wi-Fi adds an extra layer of encryption for sensitive data.
