12 excellent practices of wireless network security

There are many different steps you can take to protect your wireless network , But the following 12 Best practices can ensure that enterprise data and devices are protected from malicious attackers .

1. Enable dual authentication (2FA)

Two factor authentication adds an extra layer of security to the login process . It requires the user to enter a user name and password , And the code generated by the validator application . This makes it more difficult for some people to gain unauthorized access to the network .

If you need to enable two factor authentication , You can access the configuration page of the wireless router and enable this function . Make sure the user downloads a validator application , Such as Google authenticator or Authy, And use it at login .

Consider also using password less authentication ( Such as cloud radius) For greater protection . This is an important best practice , Because if someone manages to master someone's password , They will be able to access their network . By using cloud based solutions , It can ensure that only authorized users can access their network .

2. Use strong password

Using strong passwords is one of the most important best practices for wireless network security . Strong passwords must be at least eight characters long , Include upper and lower case letters 、 A mixture of numbers and symbols . Besides , Passwords should be changed regularly to ensure their security .

3. Encrypt data

Encrypting data is another important best practice for wireless network security . Data encryption encrypts data , It can only be decrypted and read by authorized users . This helps protect sensitive information from unauthorized personal access .

Users can implement encryption in many ways , Including through the use of encryption software 、 Hardware or services . Enterprises need to ensure that employees understand the importance of encrypting sensitive data , And make sure they know how to encrypt files correctly .

4. Ban SSID radio broadcast

In the activation of SSID After the broadcast , Anyone within the wireless network can see the network name . Users can access the configuration page of the wireless router , And disable SSID Broadcast function to disable SSID radio broadcast .

The goal is to make it more difficult for unauthorized individuals to connect to the network . If someone is in network range and uses a wireless network scanner , You can still see it SSID, But it's not that easy to access .

5. Use MAC Filter

MAC An address is a unique identifier assigned to a device connected to a network .

By allowing only certain MAC Address of the device connected to the network , Users can help prevent unauthorized access .MAC Filtering can be done by visiting the configuration page of the wireless router , And add... For devices that are allowed to connect to the network MAC Address to achieve .

6. Enable WPA3 Security

WPA3 Is the latest and most secure wireless security protocol . It provides more than WPA2 Stronger protection , Should be used whenever possible .

When choosing a router , Be sure to find a router that supports this latest security protocol . Early protocols are more vulnerable to attack , So make sure that WPA3 Very important .

7. Use VPN

VPN For equipment and VPN All traffic between servers is encrypted , Make it harder for others to eavesdrop on connections . This is using public Wi-Fi Network is especially important , Because they are usually less secure than private networks . Make sure that only... From trusted providers are used VPN, And ensure that employees understand the use of... When working remotely VPN Importance .

8. Disable Remote Administration

After enabling remote management , Anyone with the appropriate credentials can access the router's configuration page and make changes to the network . This could be a security risk , Because it allows unauthorized individuals to potentially access the network . To disable remote management , You need to access the configuration page of the wireless router and disable this function . This will help prevent unauthorized access to the network .

9. Change the default password

Many routers come with a default password that is easy to guess . This could be a security risk , Because it allows unauthorized individuals to potentially access the network .

To change the default password , You need to access the configuration page of the wireless router , And change the password to one that is more difficult to guess . Therefore, be sure to select a length of at least 8 Characters with upper and lower case letters 、 Strong passwords for numbers and symbols .

10. Use a firewall

Firewalls help protect the network by blocking unauthorized incoming traffic . This is particularly important to prevent attacks by malware and other malware .

To use firewalls , You can access the configuration page of the wireless router and enable this function . There are usually two types of firewalls ： Network based and host based . Network based firewalls are often used in business environments , Host based firewalls can be used for a single device .

11. Ban UPnP

Universal plug and play (UPnP) Is a protocol that allows devices to automatically discover and connect to each other . This could be a security risk , Because it allows unauthorized devices to potentially access the network . To disable UPnP, You can access the configuration page of the wireless router and disable this function , It can also be disabled on a single device by accessing the settings menu UPnP.

12. Disable unnecessary services

Users often find that the router has enabled many unnecessary services . These may be security risks , Because they can provide information about the network for potential attackers . To disable unnecessary services , You can access the configuration page of the wireless router and disable any unnecessary services . This will help reduce the attack surface of the network . Common unnecessary services include telnet、SSH and HTTP etc. .

Conclusion

To protect the network from potential attacks , It is important to implement these wireless network security best practices . By disabling unnecessary services 、 Change the default password and enable dual authentication , Can help make it harder for unauthorized individuals to access the network .

Besides , Use firewall and disable UPnP It also helps protect the network . By following these best practices , Can help ensure that its wireless network is secure .
