Securing Your Home Wi-Fi Network

Why Wi-Fi Security Matters

An unsecured Wi-Fi network is an open door for attackers to:

• Steal your personal and financial information
• Hijack your internet connection for illegal activities
• Infect devices on your network with malware
• Access shared files and networked devices

Basic Router Security

Start with these essential router settings:

1. Change default credentials: Admin username and password
2. Update firmware: Check for and install the latest updates
3. Disable WPS: Wi-Fi Protected Setup is vulnerable to brute force attacks
4. Enable firewall: Most routers have built-in firewall protection

Wi-Fi Encryption Standards

Use the strongest available encryption:

• WPA3: Current gold standard (if your devices support it)
• WPA2: Still secure if using AES encryption (avoid TKIP)
• Avoid: WEP and WPA (both are easily cracked)

Secure Network Configuration

Additional network hardening measures:

• Change default SSID (network name) - don't reveal personal information
• Create a strong Wi-Fi password (12+ characters, random)
• Disable remote administration
• Enable MAC address filtering for additional control (though not foolproof)
• Consider setting up a separate guest network

Smart Home Device Security

IoT devices often have weak security:

1. Place IoT devices on a separate network if possible
2. Change default passwords on all smart devices
3. Disable features you don't use (remote access, cloud services)
4. Regularly check for and install firmware updates

Ongoing Maintenance

Keep your network secure over time:

• Periodically check connected devices for anything unfamiliar
• Change Wi-Fi password every 6-12 months
• Monitor router logs for suspicious activity
• Consider upgrading older routers that no longer receive security updates
