Willem is a Hacker, Researcher and IT Specialist who is particularly well known around the world for finding cyber-security holes in popular solar inverters. <\/i><!--more--><\/p>\n<p><em>After getting an increasing number of emails from Australians who were concerned at the thought of having their solar power system exposed to the internet, I invited Willem to write a guide explaining what non-hackers like you and I can do make our inverters more secure. Over to you Willem:<\/em><\/p>\n<hr \/>\n<p>We all know that solar power is great. It helps the environment, it saves you money and is a great investment for most Australian home owners.<\/p>\n<p>But did you know that the solar inverter on your wall may pose a serious cyber security risk? Not just for your own network and data, but also for the stability of power grids as a whole!<\/p>\n<p>Following a lot of research, I was so concerned by the lack of cyber security in PV installations that I contacted several government agencies and following a responsible disclosure period, created a website called <a href=\"https:\/\/horusscenario.com\" target=\"_blank\" rel=\"noopener\">The Horus Scenario<\/a> that explains how:<\/p>\n<ul>\n<li>A malicious hacker could target the electrical grid by focusing on web connected solar inverters.<\/li>\n<li>If successful, the hacker could cause large scale (nation-wide or even continental) power outages.<\/li>\n<li>If this attack is ever truly executed in the wild, I expect it to cost billions of dollars and have a direct and severe impact on everybody\u2019s lives.<\/li>\n<\/ul>\n<p>Since this discovery, government agencies, solar inverter manufacturers, energy suppliers and some local installers are taking measures to improve the overall cyber security of inverters.<\/p>\n<p>The question now is: What can you do to protect <strong>your <\/strong>PV installation?<\/p>\n<p>Let\u2019s just start by saying that there is quite a lot you can (and should!) do.<\/p>\n<p><strong>Should you simply disconnect your solar inverter from the internet? <\/strong><\/p>\n<p>Nowadays almost all solar inverters have an internet connection via Wi-Fi or cable. The main benefit of this connection is that you can monitor the device from anywhere. The downside is that your inverter becomes a target for hackers. In some cases, your solar inverter will present itself directly as an internet facing device. In other cases, a hacker will first need to acquire access to your home\u2019s network or Wi-Fi (which is far easier than you might think, based on my experience as an ethical hacker).<\/p>\n<p><strong>Tip #1 Don\u2019t connect it to the internet if you don\u2019t have to. <\/strong><\/p>\n<p>The first tip for cybersecurity starts right there: If you don\u2019t use these applications or online portals and the device doesn\u2019t require an internet connection to function, simply do not attach it to the internet. Some solar inverters offer local monitoring via Bluetooth, USB, or by simply tapping on the touchscreen of the inverter.<\/p>\n<blockquote><p><em><strong>Editor note:<\/strong> Some inverter manufacturers require an inverter to be internet-connected under conditions of warranty.<\/em><\/p><\/blockquote>\n<p>As an alternative, you could also setup the monitoring interface to only be reachable from your local network (and for example your work Wi-Fi IP address) by <a href=\"https:\/\/www.lifewire.com\/how-to-enable-your-wireless-routers-built-in-firewall-2487668\" target=\"_blank\" rel=\"noopener\">setting up proper firewall rules<\/a>.<\/p>\n<p>When your solar inverter is not attached to the internet, an attacker needs to be physically close to try anything. The chances of a hacker physically coming to your house in order to hack your specific PV installation is tiny.<\/p>\n<p><strong>Tip #2 If you must keep it connected &#8211; follow the manufacturer\u2019s security guidelines <\/strong><\/p>\n<p>Now let\u2019s assume that you want to keep the inverter internet connected whilst still keeping it secure. There are several actions that you can take. In the rest of this guide I\u2019ll describe setting up your cyber security in the same manner a king would secure his castle.<\/p>\n<p>Any good king needs advice of trusted people. In solar this advice comes from the manufacturer\u2019s instructions!<\/p>\n<p>Reputable solar inverter manufacturers should provide detailed guidelines for setting their devices up properly. You may have to hunt around to find them, but there are usually great tips in these documents.

For example:<\/p>\n<ul>\n<li>You can implement a key lock code on the inverter, requiring physical access before any changes can be made.<\/li>\n<li>You can get access to your data via a USB stick, without allowing the inverter access to the internet.<\/li>\n<li>You can receive an SMS whenever your solar inverter shows specific errors, meaning you\u2019ll know when something is wrong, or when someone is attacking your inverter.<\/li>\n<\/ul>\n<p>Try and follow the manufacturer\u2019s guidelines to the best of your efforts. It is also possible to simply contact the help-desk and ask them to help setup your device with the correct security settings.<\/p>\n<p>If you are getting a new system installed &#8211; be there with the installer and ensure they go through any optional security settings.<\/p>\n<p><strong>Tip #3: Restrict what your solar inverter has access to. <\/strong><\/p>\n<p>Some devices simply have more privileges than others. This is normal. Your laptop needs full access to anything for usability, but your inverter really doesn\u2019t need access to Youtube, Netflix or your Xbox.<\/p>\n<p>If you\u2019re pretty good with computers and networks it is possible to set up a different network specifically for your inverter. From this network, you can allow network traffic to go from and to the solar inverter manufacturer&#8217;s servers and block everything else. Any attacker who tries to reach your inverter will never reach it because his network traffic isn\u2019t send to the device. You could even use this network for other web-connected devices. This way you can make sure that those devices and your PV installation only communicate in the way you want them to, while making sure you can still use your laptop to browse, play games and stream videos to your heart\u2019s content. <a href=\"https:\/\/www.bishopfox.com\/blog\/2016\/11\/a-guide-to-do-it-yourself-network-segmentation\/\" target=\"_blank\" rel=\"noopener\">This article shows you how to do this.<\/a><\/p>\n<p><strong>Tip #4: Get a router and configure it with a proper firewall <\/strong><\/p>\n<p>A device or a network of devices is only as strong as the weakest link in the chain. So, let\u2019s start by building a strong outer perimeter &#8211; you could consider it the &#8216;walls&#8217; to your castle.<\/p>\n<p>Set up a strong router and configure it with a proper firewall. Most mid-tier routers support this type of functionality out of the box. This firewall ensures that only the services that you want to, are exposed to the internet. Free firewall software as well as cheap consumer hardware exists that function as a firewall. Plenty of guides are available online. Here\u2019s a good \u2018for dummies\u2019 <a href=\"https:\/\/www.makeuseof.com\/tag\/configure-router-make-home-network-really-secure\/\">guide to setting up a Wireless-router securely<\/a>. And here&#8217;s a <a href=\"https:\/\/www.lifewire.com\/how-to-enable-your-wireless-routers-built-in-firewall-2487668\" target=\"_blank\" rel=\"noopener\">guide to setting up your home router&#8217;s firewall<\/a>.<\/p>\n<p>Another part of your &#8216;walls&#8217; is the Wi-Fi. Make sure your Wi-Fi device is up-to-date and keeps itself up-to-date. The recent <a href=\"https:\/\/www.krackattacks.com\/\" target=\"_blank\" rel=\"noopener\">KRACK attack<\/a>\u00a0shows that security vulnerabilities still exist in many modems and routers and installing security patches is critical. Also make sure your Wi-Fi uses a safe communication protocol and a long and complex password to keep any attackers in range of your Wi-Fi out of your network. The guide to setting up your wireless router linked to above, walks you through securing your Wi-Fi.<\/p>\n<p><strong>Tip #5: Ensure there is no \u2018backdoor\u2019 to your inverter &#8211; secure every device on your network. <\/strong><\/p>\n<p>As said before, any chain is only as strong as its weakest link. An infected device forms a direct threat to any of the devices in the same network. Every once in a while, an attacker may still sneak in to your network despite the strong firewall and outer perimeter you\u2019ve set up as per Tip #4.<\/p>\n<p>You could for example click on a dodgy e-mail or insert a friend\u2019s infected USB stick. Your now infected device can then be used to target any device in your network, including your solar inverter.<\/p>\n<p>In order to prevent the infection from spreading, you need to set up proper security on <strong>all <\/strong>your individual devices. Make sure you run updates regularly on every internet connected device in your house. Enable and set up your individual computers\u2019 firewalls, install antivirus\/antimalware software and don\u2019t install any &#8216;dubious&#8217; pieces of software. Where possible set your updates to run automatically, as doing them manually takes up a lot of time and effort.<\/p>\n<p>For solar inverters specifically, this usually means connecting them to the internet, setting them up to receive automatic updates, and following the proper security guidelines from the manufacturer. In most cases, (for example with most newer SMA inverters) setting the device up to receive updates, is a simple as changing a setting to: \u201cupdate automatically\u201d and configure your firewall to allow traffic from the device to the SMA update servers and back.<\/p>\n<p>Some older inverter models or PV-related hardware however, cannot be updated over the air as they are too old to have an internet connection. For these unconnected devices, you should check at least annually if updates are available and then manually install new firmware according to the vendor\u2019s instructions.<\/p>\n<p>If you have internet-connected legacy devices that are unsupported (e.g. SMA Sunny WebBox) you will never receive updates. Treat these devices as hazardous devices, as any security vulnerabilities that may exist in them, will never be solved (old windows 2000 and XP devices are a great example of this!). Where possible, I recommend replacing these devices, as better and more secure alternatives are usually available. If you cannot replace them, make sure you place the device in a separate network segment (a sort of quarantine space), to which only specific whitelisted network traffic is allowed.<\/p>\n<p><strong>Tip #6: Change the password for every configured user of the inverter <\/strong><\/p>\n<p>Most inverters come with default users and corresponding passwords. These default users and passwords should be changed by you as soon as possible. Make sure <strong>you <\/strong>determine the password yourself for <strong>ALL <\/strong>users. Local installers often have one password for all their clients. That\u2019s not very secure, so make sure you change the password for all users of the inverter. SMA solar inverters for example, come with a user login (default password 0000) and installer login (default password 1111) for which the passwords can be changed by you. You, as owner of the device, should be the only one who has access to both the user password and the installer password of the device. Whenever an installer has to adjust the settings of the device he can simply ask you for the password.<\/p>\n<p>Also make sure to use different (not your personal default) passwords for all these accounts. Solar inverters can use very weak encryption on passwords, allowing eavesdropping attackers to decrypt the password. If you use the same password on your inverter as you\u2019ve used on your banking account or e-mail, an attacker who compromises your inverter might get far more than \u201cjust\u201d your inverter password.<\/p>\n<p>I strongly recommend using a password-safe and setting up true random passwords with a 16 char+ (or as long and complex as possible if the device\/service doesn\u2019t allow 16+ characters) length on all the services and devices you use. This improves your overall security enormously, and password safes nowadays are very easy to use.<\/p>\n<p><strong>Tip #7: Two factor authentication <\/strong><\/p>\n<p>This step involves using two factor authentication where possible. No solar inverters that I know of support this right now, but newer models or online login portals may do so in the future. Two factor authentication usually involves getting a code from your mobile phone and using it as an additional \u201cpassword\u201d.<\/p>\n<p>What this effectively does, is make sure that an attacker not only needs to know your password, but would also need access to your mobile phone. Odds are, that an attacker doesn\u2019t have this access. Even better, when an attempted sign-in is made, the &#8216;guards of your castle&#8217; notify you that someone is trying to get in using your password. You can then simply deny them access and change the password as you are now aware that someone else knows your password.<\/p>\n<p><strong>Phew! Your solar inverter is now secure <\/strong><\/p>\n<p>With everything in place not only is your solar inverter secure, but all your devices and accounts are. The thing with cybersecurity, is that it is never about a single device (in this case the inverter). Keeping up a high level of cyber security requires discipline and effort on all your devices. To complicate matters, it doesn\u2019t just require effort and discipline on your side, but also on the installer\u2019s and the manufacturer\u2019s side. You can only set up your web connected solar power system as securely as possible and hope that others will follow your example.<\/p>\n<p>There\u2019s always a chance that an advanced attacker with a lot of dedication might still slip in and hack your device, but with a castle set up like this, the ordinary script-kiddie or web-bot will have no chance against your mighty defenses.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Note from Finn: Please welcome\u00a0Willem Westerhof to the\u00a0SolarQuotes\u00ae Blog.
