let's hack your home network // FREE CCNA // EP 9

Summary by Krater

The host tests a home network for vulnerabilities using Nmap and vulnerability scanners, finding multiple open ports and potential attack vectors. He concludes by demonstrating six steps to secure and harden a home network, including using a VPN, disabling remote management, and segregating IoT devices.

Answers: How can I test my home network for vulnerabilities and secure my router?

• home network security
• network vulnerability scanning
• router hardening
• Nmap port scanning
• network segmentation and VLANs
• VPN usage

What it concludes

• Most home networks are not safe from external attacks and contain open ports and vulnerabilities.
• Using a VPN hides your public IP address from the internet, but all other devices on the home network still use your real public IP.
• Enabling the SPI firewall and disabling remote management on your router prevents external actors from accessing your administration portal.
• Port forwarding allows outside connections into your network and should be disabled unless strictly necessary.
• IoT devices should be placed on a separate VLAN using client isolation to prevent them from communicating with trusted devices or the wider network.
• Updating router firmware and using custom firmware like DD-WRT or enterprise hardware like Ubiquiti Unifi or Cisco ASA improves network security.
