Wireless security combines encryption, authentication, access control, device security, and intrusion detection to create a multi-layered defense against unauthorized access and ensure network security.
First, adopt advanced wireless network encryption methods (such as WPA2 or WPA3) to disrupt data transmission. Encrypted data cannot be read by unauthorized personnel, even if intercepted. Second, users or devices seeking to connect to the network are prompted to verify their identity, typically using a password, to confirm the legitimacy of the connection request. Access control rules then specify which users or devices are allowed access to the network and the level of access granted to them based on user roles, device types, and explicit access rights. Network devices are further protected by maintaining antivirus software, updating operating systems, and restricting the use of administrator credentials to prevent unwanted access. Finally, integrated intrusion detection and prevention systems (IDPS) and other tools monitor the network for any unusual activity or security breaches. These systems detect and respond to unauthorized access attempts, malware infections, and other threats in real time, providing proactive protection. Data encryption: Converts data into something readable only by authorized users with the appropriate key.
Authenticating users and devices: Determines the identity of individuals and devices connecting to the wireless network.
Applying access control rules: Limits the content accessible to users and devices.
Secure and trusted devices: Hardware-based identity verification, behavior control, data protection, and risk traceability.
Intrusion detection and prevention tools: Detect and prevent suspicious activity and security breaches within the network.

WEP, WPA, WPA2, and WPA3 are four wireless network security protocols, each offering increasing security. WEP is an outdated Wi-Fi security protocol and should be avoided. WPA is an enhanced replacement for WEP. While WPA2, which uses AES encryption, is a commonly used protocol, WPA3 offers additional security features, such as stronger encryption and attack protection. These protocols determine the access levels of users and devices. Regardless of the protocol used, strong security measures are essential to protect your wireless network and sensitive data.

When using personal wireless devices, you should also take care to protect your data. First, we recommend updating to the latest encryption protocols to maximize network security and prevent potential threats and data leaks. Secondly, consider increasing the difficulty of cracking by avoiding personal information such as your last name in the SSID. Using uncommon information makes it more difficult for hackers to attack your network using techniques like "evil twin" attacks. Hiding the SSID also reduces the risk of rogue access points and unauthorized access, thereby improving the overall security of your wireless network.

For business users, in addition to preventing wireless network attacks, ensuring regulatory compliance and customer trust is crucial. Regarding password management, share passwords only with relevant personnel and change them regularly to ensure security. To protect your company's sensitive data, direct visitor and non-business activities to separate networks, regularly verify and remove unauthorized devices, and consider partnering with a network security vendor for a comprehensive wireless network security solution.
