docker vpn server raspberry pi

The next big one was the half name attack on Microsoft Exchange. I've just followed this on my rpi3 The input chain default policy is set to drop with input chain rules to allow connections on the BlastShield interface and to allow the related and established connection state. Docker is now widely used by software engineers and DevOps teams because it speeds up software development and simplifies the packaging and distribution of applications. So we know we are continuing to invest in this technology. So most of what you described isn't particularly sophisticated, but I haven't met anyone yet that said, they fell victim to an unsophisticated attack. If you are in need of your own VPN server, the easiest way is to create one with OpenVPN and docker. Now they want to poke around. Thanks so much for taking time to speak with me and to shed some light on blast play. And so while it's a great attempt, these are really complicated, prone to human error. In the case of SolarWinds, if we look at that real quickly, SolarWinds was a perfect example of that. To connect to the VPN server, the ovpn file that was created in the previous step is required by the vpn clients. First of all, malicious actors perform reconnaissance or recon try to scan and see what assets and vulnerabilities exist. Yesterday, a colleague of mine, Paul Gracie put out an article. You can also change some of your preferences. Since these providers may collect personal data like your IP address we allow you to block them here. So thank you for your time. If you find you have more questions on this area then read and/or watch some of them below! This inhibits the ability for, let's say an actor pretending to be one of your remote users that connected into your network to now poke around because they can't see other systems, unless they're granted a specific access to this. They had identified through surveillance and reconnaissance, a system that was vulnerable inside the SolarWinds build servers. You can sign-up for a free account, Docker should be installed on the Raspberry Pi. And that's 20 doors of entry for a malicious actor. They perform lateral movement to do recon within the network, deploy a payload, establish a backdoor, etc. Starting with the solar winds attack, which was the supply chain attack, state actors perform reconnaissance on the solar winds network. From there, they try to gain access to the network through the weakest link. And so if we think about that, it makes sense. So it's usually a combination of three technologies in the wide area network. From there, that instance replicated itself up to other systems and then created a command and control channel back home, using the security technologies that we spent 20 some odd billion dollars on this year or not using them effectively bypassing them. This method works equally well on cloud server infrastructure to combine cloud instances on the same network as the Raspberry Pi. A year ago, TECHBASE released an updated version of the ModBerry M500 industrial IoT computer, replacing the aging Raspberry Pi 3 with a 3B+, giving it better performance. I recommend using something like Docker Compose to store all of the configuration and then ensuring that docker-compose script runs on restart. ModBerry devices are compatible with Raspberry Pi accessories, supported by Raspberry Pi Foundation. And so you can envision a scenario where in the event that maybe somebody walked through the door and dropped a piece of code onto a server. That Yeah, and then the next last week, the colonial pipeline attack was really bad. Additionally, you can reach us at www.blastwave.io, and we would love to have communication with you. First, this again is the link to Paul's article that he wrote. In recent years, they tried to put together these SD LAN products Software Defined wide area networks in response to the dilemma. And what we mean by that is that the devices that sit down here that perform the authentication process are largely unaware of what policies for access you might be granted or not granted. Your submission has been received! Yeah, well, really, there's no magic to this, whether it's carried out in applications data, mechanical industrial systems, attacks really only come through two sources, either physical or through the network. I think the second though, is there's this blurring of lines between cyber criminal groups and state actors to conduct political espionage or cyber warfare. It also allows multiple applications to co-exist with each other. Copyright BlastWave, Inc. All Rights Reserved. Once installed on the Raspberry Pi, the Agent will encrypt connections between the Raspberry Pi and authorized remote users. In fact, there's an entire framework that describes is called the cyber Kill Chain. This will reduce the time it takes to set up remote access, reduce the risk of credential theft, and make it easy to share access with a defined group of remote users.

The majority of VPN vendors also use the exact same SSL VPN stack, which makes it trivial for malicious actors to identify their products. And the past, we could just tack up VPN client server solutions, but those days are gone. This means that you can assign policies to containers based on the published port number, allowing remote access only to the port on that container. So we've got to break that cyber Kill Chain I talked about. When I reboot raspberry pi 3 with sudo reboot command after the installation of the configuration above, the connection will be lost. Here's a video showing how authentication works: Once authenticated, you can connect to the Raspberry Pi using your preferred connection method. You can't talk to it. However it's a custom image and I haven't got time to test. And they're a hacker performed, guess what reconnaissance to the plant to discover how best to gain remote access through the TeamViewer. Connect to your BlastShield network and open the Orchestrator in your web browser. And then there's a lot going on at the network level. Well, if you start with reconnaissance since this network and the assets that are protected behind it are invisible, then it makes it really difficult for reconnaissance to be performed because you can't identify those assets. Well, Let's take a look at the statistics. Yeah, now we're getting down to the most important part in terms of what do we do about it? This site uses cookies. 70 known vulnerabilities from companies who are the leaders in providing virtual, private networking technology. So what new approach Do we need to take now to defending these entry points to the network? And the last thing I would do is make the product very lightweight and software base so you could effectively run it anywhere. Today, I want to talk about persistent threats. And statistically speaking, most of it comes through the network. But as I said, it's a short article. Now, if we move over to the left and look at the remote user, I think we're, beginning to do a good job by applying multi-factor authentication. Hello So they're usually highly vulnerable to theft, but more importantly, they're not policy-aware. And then there's this complexity around provisioning, and setting control access and almost an infinite number of combinations of human to application human to machine, machine to machine and machine to application. Number four, make it easy to deploy, provision and configure. Step 4: Configure policy to allow access to the Agent. If we look at the leading vendors in this space, and we're not gonna mention any names, but you could see them. How to Setup PiVPN on the Raspberry Pi Tutorial, Maintainer post about where to properly place a VPN, Create your own VPN server with the Raspberry Pi, PiVPN - Create your own VPN for your home network. I think you can find a copy on https://github.com/lunderhage/docker-openvpn-rpi. You need to use something else on you raspberry pi to ensure that docker is started up. Hold on. Now you can reconnect to the Agent using the BlastShield secure access, using the BlastShield Mobile Authenticator app to authenticate. The security of our data and our customers data is our highest priority and we needed a secure platform to provide access to our hybrid data services, hosted both in the cloud and on-premise. Since we are running the container as a named instance (name openvpn), the name of the container can be used to start or stop the container. Over 10 million Raspberry Pis have been sold and the Raspberry Pi is likely to stay as a new standard in the industry. Usually it is well, not usually it is in fact, very prone to human error, more than 90% of all vulnerabilities and outages within networks today, come from human error. It called out some burning problems that we have in the cybersecurity space today. Because these cookies are strictly necessary to deliver the website, you cannot refuse them without impacting how our site functions. How to install OpenVPN with Docker on Raspberry Pi. Well, everything I just described to you are the pillars of our flagship product blast shield, so deploys over any packet based network. Number three, we need to ensure that the connection is truly edge to edge. Create a group for your user(s). It brought down 45% of the fuel supply on the east coast. In the case of the Hafnium attack, it was a very similar scenario. And again, actors were able to get inside the secure network most likely through compromised credit. But it is worth the try as docker allows us to re-create a new VPN server in no time without disturbing the host Operating System. The links below showcase some good write-ups and tutorials that use PiVPN. To be able to protect your client's identity, and then within your local area network, where your protected systems and applications lie, you attempt to protect those through access control and segmentation. It is. Then click on the red "Save and Download Invitation" button and choose the option for "Save and copy Linux/macOS installation command to the clipboard". Then they performed recon to identify the Exchange servers. And the reason that we use that model is it makes it immune to your common phishing exploits, but also reduces the risk of theft because of the requirement of multiple surfaces. And then finally since BlastShield effectively creates this air gap around these assets, it's effectively air-gapping the malware as well. This is a game of whack a mole that the industry stuck in. https://iot-industrial-devices.com/wp-content/uploads/2020/01/raspberry-pi-docker-vpn.png, https://iot-industrial-devices.com/wp-content/uploads/2019/11/iot-industrial-devices-1.png, Docker VPN-based Raspberry Pi Server tutorial, Copyright - IoT Industrial Devices 2019, Raspberry Pi based controller with Modbus, M-Bus & MQTT support, Linux Kernel 5.5 brings changes to ARM, RISC-V and MIPS, replacing the aging Raspberry Pi 3 with a 3B+, Smart Home global trend makes IoT more relevant than ever before, Industrial Edge Computing with Dual Compute Module 4 Cluster, Meter monitoring during pandemic with Wireless M-Bus, IoT is more relevant than ever thanks to the smart home trend, New Wi-Fi 6 802.11ax chip from NXP Semiconductors. And today, kids can learn how to hack into networks simply by watching YouTube videos, and downloading kits running these things from the dark web or internet. Note: I don't think you'd have to do anything with iptables as he shows. So the network itself, the BlastShield network and all protected systems are effectively invisible. But, there is a popular docker image named kylemanna/openvpn with more than 10 Million docker pull requests. BlastShield is a zero-trust access solution, so you must provision a policy to authorise access to the Agent on the Raspberry Pi before you can connect to it. But the real question is, is anyone really doing anything to attempt to create a line of defense against these attacks? In what ways do you now see security requirements getting so complex, that they're exceeding the capabilities of current protection solutions? And cyber criminals are almost like a well paid some subcontractor for these state actors. And it's all manageable from a single policy orchestrator. And at BlastWave, we would argue that for the most part, they're not. Oops! Command: sudo docker run -v openvpn_data:/etc/openvpn --rm evolvedm/openvpn-rpi ovpn_getclient CLIENT > CLIENT.ovpn Well said, Tom, I appreciate your time today. It was a little bit cheeky and effectively. When the process has completed you will see the following message in the terminal window: You can also verify the Agent status using systemctl. app. Well, I think we fundamentally need to rethink network security. Any clue why ? You will also need a BlastShield Orchestrator, which you'll need to register and connect to. At this time of writing, there is no official docker image available from OpenVPN. I'm not a real fan of giving your data security to other's containers, so if you want to compile your own image, you can use this repo: https://github.com/evolvedm/docker-openvpn-rpi/blob/dc6159c0738a67802444a3a16ecfe6cb4e508280/Dockerfile. So all of those hundred plus exploits we just saw today, it is immune to those. I used the, An ARM-compatible Docker image to run on the Raspberry Pi. And then lastly, you put the entire network provisioning and management console in an orchestrator that's hosted within the blashill network. https://github.com/lunderhage/docker-openvpn-rpi, https://docs.docker.com/engine/reference/commandline/run/#restart-policies---restart. Somebody made a configuration change that caused either an outage or a gap and created an opportunity. Thank you for your time. All went wel until the getclient. Use it with care! In what ways would you say our adversaries are upping their sophistication? Where do you see some of the current protection technologies most obviously failing? This website uses cookies to ensure you get the best experience. Really pleased to welcome to the studio Tom Sego is the founder and CEO of BlastWave Inc. Tom, thanks so much for taking time to speak with me. Well, that's exactly what I asked you about. Clone with Git or checkout with SVN using the repositorys web address. This shows connecting with Windows client. You can steal a single thing, and once you've stolen that single thing, a key fob, etcetera, then now they can take that and pretend to be you anywhere else in the world. Changes will take effect once you reload the page. Again, I'm Tom Field with Information security Media Group. Items on this page can be outdated, and they should be taken only as references. You can watch a 2 minute video on how to add a new Agent here: Step 2: Install the Agent on the Raspberry Pi. BlastShield is a software-defined private network overlay that can be deployed over any packet based network. With therecent launch of the Raspberry Pi 4, TECHBASE has yet again, announced another upgrade to theM500, which now packs the latest single-board computer. Access authorization is done by zero-trust with a default drop policy. While they all may look unique in their approach, they all use a very common pattern. BlastShield is built on a proprietary transport methodology that is immune to SSL, BP, and exploits. Yeah, well, I think there's three trends that are enabling that sophistication. We may request cookies to be set on your device. By now, I'm assuming that most of you have either heard about the recent persistent threat attacks - one being the sunburst attack on solar winds, secondarily the happening of attack on Microsoft exchange, or perhaps unfortunately your organization has been a part of those as a victim. Create a policy to link the user group to the Agent group in the direction you want. If we were to look at them and ask ourselves, well, how secure are these particular vendor solutions? And then more importantly, within that multi-factor authentication process, your users, access and visibility are bound to each other by policy. There's the VPN technology itself is 25 years old, and almost no innovations are occurring. In this blog, I will describe how to set up secure remote access to Docker workloads using a BlastShield Agent. So we've got to create that line of defense. Now, why do we care about this? Get secure remote access from anywhere via your own VPN based on Docker containers. Response: -bash: CLIENT.ovpn: Permission denied. Hey, welcome back. You could also create a service in the Orchestrator to define the port on which you publish a container and then add that service to your access policy. And so I want to walk through this and I'm going to use a combination of a PowerPoint and some information off the web to go through the disk. And we can see that right now, there are roughly 20 known vulnerabilities that range from pretty severe to maybe reasonably severe. networks in devices and factories used to be air gapped and immune from network borne malware. Now we all recognize we don't live in a perfect world. And guess how they started, they perform recon, they gained network access through compromised credentials or through a VPN exploit. Also, you can use the BlastShield Agent to access the container directly. I'm going to show you how to set this up. To securely share access to containers running on the Pi with other remote users, you can install a BlastShield Agent. Number five make it easy to use without requiring extensive training or changes to the network underlay. And so by that fact, that puts them in a position where this network is kind of a set of disparate parts. Along with that. If you want to speak to Paul live, this is a QR link to his LinkedIn profile. It's a very time consuming process for network engineers. So this is the QR link. $ sudo iptables -A INPUT -i blastshield -m conntrack --ctstate NEW,ESTABLISHED -j ACCEPT, $ sudo iptables -A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT, $ sudo iptables -I FORWARD 1 ! And if we take a look at these attacks, we can see that that's the case. Because, when I have an electricity problem(same as rebooting the raspberry pi3), I also lost the connection and the .ovpn file won't work anymore. Step 3: The Agent will auto-start and register with the Orchestrator. To stop the container, execute the command docker stop openvpn. Next, they perform internal reconnaissance to identify the high value asset servers and data within that land. Make sure these rules appear above any Docker rules, and always have a means to locally access your Raspberry Pi when making changes to iptables in case you make a mistake and lock yourself out. We also use different external services like Google Webfonts, Google Maps and external Video providers. To start the container, execute the command docker start openvpn in the terminal. And now you have public cloud hybrid cloud on prem, and even the employees home as part of that corporate network now. Effectively it delivers this encrypted edge to edge network that runs across the entirety from your edge user, into your application. And then from there deliver a piece of malicious payload onto that. So, we need to ask ourselves, why do we care about this? That may be a publicly known vulnerability as the list that we just went through a moment ago, or it might be a personal or a private vulnerability that they have discovered. From there, there was a publicly known vulnerability that bypass the authentication process. Then finally, if we look at number three, which is a very well-known name, and we look at theirs - 70. So number one, we have to stop both external and internal reconnaissance by making those networks invisible and unresponsive to network scanning.
