How to Secure Your Wireless Network: Wireless Security Best Practices
Learn how to protect your wireless network from potential threats.
- Use Strong Encryption
Choose the highest level of encryption available for your wireless network. Currently, Wi-Fi Protected Access 3 (WPA3) is the most secure encryption protocol. If your router doesn’t support WPA3, use WPA2 instead. Avoid using the outdated and vulnerable Wired Equivalent Privacy (WEP) encryption.
- Change the Default Router Login Credentials
Most routers come with default login credentials, which are often easy for hackers to find. Change the default username and password to protect your network from unauthorised access. Use strong, unique passwords that combine uppercase and lowercase letters, numbers, and special characters.
- Set Up a Secure Wi-Fi Password
Create a strong, unique password for your Wi-Fi network. Aim for at least 12 characters and include a mix of uppercase and lowercase letters, numbers, and special characters. Avoid using easily guessable information, such as names, birth dates, or common phrases.
- Update Router Firmware Regularly
Manufacturers release firmware updates to fix security vulnerabilities and improve performance. Keep your router’s firmware up to date to ensure optimal security. Consider enabling automatic updates if your router supports it.
- Disable Remote Administration
Some routers allow remote administration, which can be a security risk. Disable this feature to prevent unauthorised access to your router’s settings. If you need remote access, use a secure method like a Virtual Private Network (VPN).
- Enable Network Address Translation (NAT)
NAT acts as a firewall by hiding your devices’ IP addresses from the internet. Enable NAT on your router to improve security and protect your devices from potential attacks.
- Turn on the Router’s Firewall
Most routers have a built-in firewall that helps protect your network from external threats. Make sure the firewall is enabled and configured correctly. Consult with IT professionals for assistance with configuring your firewall.
- Use a Guest Network
Create a separate guest network for visitors, so they don’t have access to your primary network. This reduces the risk of unauthorised access to your devices and sensitive data.
- Disable Wi-Fi Protected Setup (WPS)
WPS simplifies the process of connecting devices to a Wi-Fi network but can be vulnerable to attacks. Disable WPS on your router to enhance security.
- Regularly Monitor Your Network
Monitor your network for unauthorised access and potential security threats. Use RMM tools to gain insights into your network’s performance and address any issues promptly.
- Position Your Router Strategically
Place your router in a central location to provide even coverage and reduce the risk of signal leakage. Keep the router away from windows and exterior walls to limit signal range outside your premises.
- Secure Your Devices
Ensure all devices connected to your wireless network have updated software, strong passwords, and up-to-date security measures. Read about remote work security tips for more information on securing your devices.
- Educate Your Staff
Train your employees on best practices for maintaining a secure wireless network. This includes using strong passwords, avoiding suspicious email attachments, and staying informed about the latest security threats.
- Consider a VPN
Using a VPN can add an extra layer of security to your wireless network by encrypting all data transmitted between your devices and the internet.
- Disable SSID Broadcasting
Disabling the SSID (Service Set Identifier) broadcasting feature on your router can make it more difficult for nearby users to find your network. While this is not a fool proof security measure, it can deter casual hackers from attempting to connect to your Wi-Fi.
- Use MAC Address Filtering
MAC address filtering allows you to control which devices can connect to your wireless network. Add the MAC addresses of your trusted devices to the allowed list, and block any unknown or suspicious devices.
- Schedule Regular Security Audits
Conduct regular security audits to evaluate the effectiveness of your wireless network security measures. Identify any vulnerabilities and implement necessary changes to ensure your network remains secure.
- Update Connected Devices
Regularly update the software and firmware of all devices connected to your wireless network. This includes smartphones, tablets, laptops, and IoT devices. Keeping your devices updated helps patch security vulnerabilities and improve overall network security.
- Monitor and Limit IoT Devices
IoT devices can pose a security risk if they are not properly secured. Monitor IoT devices connected to your network and limit their access to essential functions. Keep their software updated and use strong, unique passwords for each device.
- Consult with IT Security Professionals
Engage with IT security professionals for expert advice on securing your wireless network. These professionals can help you implement the best security practices and provide recommendations tailored to your unique needs. Consider leveraging comprehensive IT security solutions to protect your network and devices from potential threats.
