What methods increase wireless network security?

Wireless network security can be increased through encryption, secure passwords, network firewalls, and regular software updates.

Encryption is a key method to increase wireless network security. It involves converting data into a code to prevent unauthorised access. The most common encryption protocols are WEP, WPA, and WPA2, with WPA3 being the latest and most secure. However, WPA2 is still widely used and provides a good level of security. Encryption works by scrambling the data transmitted over the network, making it unreadable to anyone without the correct decryption key.

Secure passwords are another crucial aspect of wireless network security. A strong password should be long, complex, and unique. It should include a mix of uppercase and lowercase letters, numbers, and special characters. The use of a password manager can help to generate and store such passwords. Additionally, changing the default username and password of your router can prevent unauthorised access.

Network firewalls provide a further layer of security. A firewall monitors and controls incoming and outgoing network traffic based on predetermined security rules. It establishes a barrier between a trusted internal network and untrusted external networks. Most routers have a built-in firewall that can be configured to enhance security. It's also advisable to install a software firewall on individual devices for an extra layer of protection.

Regular software updates are also essential for wireless network security. Updates often include patches for security vulnerabilities that have been discovered since the last version of the software was released. Keeping your router's firmware, your devices' operating systems, and your security software up to date ensures you are protected against the latest known threats.

Lastly, disabling remote management of your router, changing the network's SSID (Service Set Identifier), and enabling network filtering are additional steps that can be taken to increase wireless network security. Remote management can be exploited by hackers to gain control of your network. Changing the SSID makes your network less visible to casual hackers, and network filtering allows you to control which devices can connect to your network.
