**Use a secure VPN Protocol** | Optional | [OpenVPN](https://en.wikipedia.org/wiki/OpenVPN) is widley used, and currently considered a secure [tunneling protocol](https://en.wikipedia.org/wiki/Tunneling_protocol), it's also open source, lightweight and effiecient. [L2TP](https://en.wikipedia.org/wiki/Layer_2_Tunneling_Protocol) can be good, but only when configured correctly, whereas it's much harder to go wrong with OpenVPN. Don't use [PPTP](https://en.wikipedia.org/wiki/Point-to-Point_Tunneling_Protocol), which is now legacy, and not considered secure, and avoid [SSTP](https://en.wikipedia.org/wiki/Secure_Socket_Tunneling_Protocol) (proprietary, owned by Microsoft and due to lack of transparency, could be vulnrable to exploits). [IKEv2](https://en.wikipedia.org/wiki/Internet_Key_Exchange) and [WireGuard](https://www.wireguard.com/) *(experimental)* are also good options. **Use a secure VPN Protocol** | Optional | [OpenVPN](https://en.wikipedia.org/wiki/OpenVPN) is widley used, and currently considered a secure [tunneling protocol](https://en.wikipedia.org/wiki/Tunneling_protocol), it's also open source, lightweight and effiecient.

**Avoid the free router from your ISP** | Optional | Typically theyre manufactured cheaply in bulk in China, and firmware updates which fix crucial security flaws arent released regularly. Consider an open source based router, such as [Turris MOX](https://www.turris.cz/en/mox/overview/) **Avoid the free router from your ISP** | Optional | Typically theyre manufactured cheaply in bulk in China, and firmware updates which fix crucial security flaws arent released regularly.

**Ideally hide your SSID** | Optional | An SSID (or Service Set Identifier) is simply your network name. If it is not visible, it is much less likely to be targeted. You can usually hide it after logging into your router admin panel, [see here for more details](https://www.lifewire.com/hide-your-wireless-network-from-your-internet-leeching-neighbors-2487655). **Ideally hide your SSID** | Optional | An SSID (or Service Set Identifier) is simply your network name.

**Whitelist MAC Addresses** | Optional | As well as a strong password, and hidden SSID, you can whitelist MAC addresses in your router settings, disallowing any unknown devices to connect to your network. A malicous actor can bipass this, by making their address appear the same as one of your trusted devices, but it will add an extra step for them. **Whitelist MAC Addresses** | Optional | As well as a strong password, and hidden SSID, you can whitelist MAC addresses in your router settings, disallowing any unknown devices to immediatley connect to your network, even if they know your credentials. A malicous actor can bipass this, by cloning their address to appear the same as one of your trusted devices, but it will add an extra step for them.
**Use the Tor Network** | Advanced | VPNs have their weaknesses, since the provider knows your real details, whereas Tor is anonymous. For optimum security, route all your internet traffic through tthe Tor network. On Linux you can use [TorSocks](https://gitweb.torproject.org/torsocks.git) and [Privoxy](https://www.privoxy.org/), for Windows you can use [Whonix](https://www.whonix.org/), and on OSX [follow thsese instructions](https://maymay.net/blog/2013/02/20/howto-use-tor-for-all-network-traffic-by-default-on-mac-os-x/). Finally, you can use [OnionPi](https://learn.adafruit.com/onion-pi/overview) to use Tor for all your connected devices, by [configuring a Raspberry Pi to be a Tor Hotspot](https://lifehacker.com/how-to-anonymize-your-browsing-with-a-tor-powered-raspb-1793869805) **Use the Tor Network** | Advanced | VPNs have their weaknesses, since the provider knows your real details, whereas Tor is anonymous.

**Kill unused process and services on your router** | Advanced | Services like Telnet and SSH (Secure Shell) that provide command-line access to devices should never be exposed to the internet and should also be disabled on the local network unless they're actually needed. In general, [any service thats not used should be disabled](https://www.securityevaluators.com/knowledge/case_studies/routers/soho_service_hacks.php) to reduce attack surface. **Kill unused process and services on your router** | Advanced | Services like Telnet and SSH (Secure Shell) that provide command-line access to devices should never be exposed to the internet and should also be disabled on the local network unless they're actually needed.

**Disable WiFi on all Devices** | Advanced | Connecting to even a secure WiFi network increases your attack surface. Disabling your home WiFi and connect each device via Ethernet, and turning off WiFi on your phone and using a USB-C/ Lightening to Ethernet cable will protect against WiFi exploits, as Edward Snowden [says here](https://twitter.com/snowden/status/1175431946958233600?lang=en).
