Wireless Security Settings
1. WPA3 (Wi-Fi Protected Access 3)
WPA3 is the latest security protocol for wireless networks, designed to provide stronger encryption and improved security compared to its predecessors, WPA2 and WPA. WPA3 uses the Simultaneous Authentication of Equals (SAE) protocol for enhanced protection against brute-force attacks.
Key Features:
- Enhanced Encryption: Uses 192-bit encryption for better security.
- Forward Secrecy: Ensures that even if a session key is compromised, past sessions remain secure.
- Improved Authentication: Provides stronger protection against dictionary attacks.
Example:
In a corporate environment, enabling WPA3 on your MikroTik wireless router ensures that sensitive business data transmitted over the Wi-Fi network is protected from unauthorized access and sophisticated hacking attempts.
2. MAC Filtering
MAC Filtering is a security feature that allows or denies access to the wireless network based on the Media Access Control (MAC) address of the device. Each network interface has a unique MAC address, making it a reliable method for controlling network access.
Key Features:
- Device-Specific Control: Allows only specified devices with known MAC addresses to connect to the network.
- Enhanced Security: Provides an additional layer of security by limiting access to trusted devices.
- Easy Configuration: Can be easily set up on MikroTik routers to create a whitelist or blacklist of MAC addresses.
Example:
In a university dormitory, enabling MAC Filtering on the MikroTik wireless router ensures that only authorized students' devices can connect to the Wi-Fi network, preventing unauthorized access and potential security breaches.
3. RADIUS Authentication
RADIUS (Remote Authentication Dial-In User Service) is a network protocol used for centralized authentication, authorization, and accounting (AAA) management. It allows for secure user authentication and access control to the wireless network.
Key Features:
- Centralized Management: Provides a centralized server for managing user credentials and access policies.
- Secure Authentication: Uses strong encryption methods to protect user credentials during transmission.
- Flexible Access Control: Allows for fine-grained control over user access to network resources.
Example:
In a large enterprise, implementing RADIUS authentication on MikroTik wireless routers ensures that only employees with valid credentials can access the corporate Wi-Fi network. This centralized management system enhances security and simplifies user access control.
