Protecting all the devices on a home network from malware and lateral movement requires a multi-layered approach. Here are some tips:

1. Use a Firewall: A firewall helps to filter out unauthorized incoming and outgoing network traffic. Make sure that you have a firewall enabled on your home router.

2. Keep your operating system and applications up-to-date: Make sure that all your devices have the latest security updates and patches installed. This can help to close any known vulnerabilities that could be exploited by malware.

3. Use Anti-Malware Software: Install and regularly update anti-malware software on all your devices. This can help to detect and remove malware infections.

4. Enable Network-level Protection: Many home routers come with network-level protection that can detect and block known malicious websites, phishing attempts, and other threats.

5. Use strong passwords and two-factor authentication: Use strong, unique passwords for each device and account, and consider enabling two-factor authentication where possible.

6. Enable Encryption: Enable encryption on your Wi-Fi network, and use HTTPS wherever possible to protect your online communications from eavesdropping.

7. Regularly backup your important data: In the event of a malware infection, having a recent backup of your important data can help you to recover quickly without losing any valuable information.

By following these tips, you can help to protect all the devices on your home network from malware and lateral movement.
