Hardware Firewall On a USB Key 203

Posted by kdawson
from the bad-packets-stop-here dept.
An anonymous reader writes "An Israeli startup has squeezed a complete hardware firewall into a USB key. The 'Yoggie Pico' from Yoggie Systems runs Linux 2.6 along with 13 security applications on a 520MHz PXA270, an Intel processor typically used in high-end smartphones. The Pico works in conjunction with Windows XP or Vista drivers that hijack traffic at network layers 2-3, below the TCP/IP stack, and route it to USB, where the Yoggie analyzes and filters traffic at close-to-100Mbps wireline speeds. The device will hit big-box retailers in the US this month at a price of $180." Linux and Mac drivers are planned, according to the article.

    A true hardware firewall wouldn't have to hijack traffic via a driver. It would have it's own ethernet port and would inspect data before it even touches the network stack on the host OS.

    A bit hyped up if you ask me.

        It might not offer better protection than a software firewall, but it will offload the work to it's own processor freeing up cycles on your computer. If you are pushing your machine this could be a fairly inexpensive way to squeeze a little more life out of an older /underpowered box.

            I think that is exactly the point the grandparent was trying to make. If it had an actual ethernet interface you would only have to transfer the packets over the USB interface once, thus you'd reduce the load on the machine. You'd also get better security since the machine would no longer be connected to the network without going through the firewall. You'd avoid hacking the network stack, and the result would be something working on more systems without the need for special drivers. And you'd free up the ethernet port on the machine, so it could also be used in situations where the machine did not have exactly as many ethernet connections as you'd want. Basically adding a real ethernet interface to this gadget would have increased its value by at least a factor of two.

It sits in the same place as a software firewall, but offloads the calculations and filtering to the dongle's cpu.

      A hardware firewall is a firewall that runs on separate hardware from the hosts that it protects. In other words, it's a software firewall on a dedicated machine, which may or may not have specialized packet-filtering hardware. The "hardware/software" distinction made by marketeers isn't really important; more significant is the distinction between "network firewalls" and "host firewalls". Network firewalls are separate devices that are capable of filtering all traffic entering or leaving a network of multiple computers; host firewalls are limited to the traffic entering or leaving a single host, and are normally tightly integrated with that host's operating system.

      This gimmick consists of a coprocessor and some low level operating system drivers, and appears to be primarily designed as a host firewall. It might be useful in a network firewall, it the operating system components could be ported to an operating system adequate to the task.

Anyway, I thought this device would only be any good if: 1) it had a wifi chip in the device and 2) connected via ethernet port as a mini and compact external network element that 3) would do encryption for SMB non-VPN customers 4) in unencrypted hotspots. 5) to prevent snort wifi sniffer attacks But it doesn't. Still, from what I understood they're trialling at some large enterprise IT departments who think it's super, so maybe I missed something. Nic

  • Uhm... USB 2.0 bandwidth is 54 mbps. In order to filter traffic going through it, you'd have to use the bus twice - once to send a packet to it, and once to get the packet (provided it was permitted) back from it.

    I'm sure *internally* it'd handle it at wirespeed, but... otherwise, I can't see how even 50% of wirespeed is possible. Possibly closer to 20%, which, incidentally, is still faster than most home user's bandwidth.

    And yes, this gadget's a total gimmick.

      As far as I know, the USB 2.0 fast transfer rate is 480Mbps. A rough 25% overhead rule of thumb yields a rate of 384Mbps, or 48MBps, easily enough to handle a 100Mbps ethernet connection.

      Also, you don't necessarily have to send each packet over the USB twice, if you are not doing any packet shaping, or address translation. A 1-bit response to each packet (pass / fail) is enough for a simple packet filter. The software drivers that intercepted the packet in the first place would then send the original pa

      I should get one of these. It would be great. I have this 486DX-133 playing ogg vorbis audio files and it isn't fast enough for the highest quality music. It does have a PCI USB 2.0 card in it, it would just be awesome having a 520MHz USB key doing the decoding. It would just be so backward nobody would believe me having the USB key being the CPU and the computer being storage and I/O. Goofy.

        Better idea: Just rescue a Pentium-class machine from the curb and be done with it. I know it's so obvious that it hurts, but *come on*, man.

        And then, if you still need/want extra points, remove as many of the critical moving parts from the box as you can to enhance reliability. Think undervolting, big heatsinks, and solid-state storage.

        But $180 is too much to spend just for geek cred alone.

        If that's your whole goal, then look not toward needless complication. Far better (and cheaper) results would come

    There is a niche for this thing... a very small one, but it is there.

    I, for one, might look into owning one of these. After all, I spend a shitload of time working on client machines trying to isolate and diagnose problems. Being able to plug in a USB key to emulate the hardware firewall the client *should* have would be helpful. Notice, I said emulate, not duplicate.

    Just because it is on the front page of /. does not mean it is supposed to save the world.

      Boot Knoppix. It's up, and working? The diagnosis is a blown Windows install.

      While in Knoppix, grab the Documents and Settings folder and copy to a USB drive.

      Reformat HD, reload windows, copy over Document and Settings.

  • that is really quite cool but it is clearly not a 'complete hardware firewall' as it lacks the key component of a hardware firewall.... physically separate hardware.

    Because if we had, then we might have noticed that this little device incorporates anti-virus software. Why do you care? I'll tell you why: because that eliminates one of the biggest annoyances for windows users since Clippy.

    Anti-virus software always slows down your PC. No matter what. It has to because it scans each and every file as its accessed (assuming resident scanner operations).

    This little gem allows me to not bother with installing any anti-virus software and just offload that function to a li
  • I'd rather see a device like this that is a tap based IDS or IPS system.

    You can buy taps and redirect copies of network traffic into a snort or other IDS, but I'd rather have a small all encompassing device I could take on the road.

    Wouldn't work for wireless, but I'd rather hop on a wired connection at a hotel anyways. Half the time wireless is shotty or the signal is weak.

    If I just plug the ethernet into one port and then plug my laptop into the other that would be great. It could then block traffic on non

    Dear All, Yes, I am from Yoggie and its a pleasure and honor for me to provide some "internal" information: Some of you mentioned that you need 2 network ports to make a "real" Firewall. True, please refer to our web site: www.yoggie.com and find the Yoggie Gatekeeper. This product released few months ago comes with two network ports running same processor, same memory, OS and 13 application. Some of you, view Yoggie as a Firewall and compare it to Routers and access points: Please note that Yoggie is by far more than just a Firewall and in fact its like a set of enterprise security appliances packed in a miniature computer. Lets see what's in there: 1. FireWall, NAT, DHCP Server and client 2. Full snort implementation including IPS on top. VRT updates will come soon. 3. 4 transparent proxies: 2 for web: HTTP, FTP and 2 for email: SMTP and POP3 4. True File-Type detection agent so file type are detected by content analysis and not based on MIME or file extension! Compressed file - are uncompressed in real time before scanning!!! 5. Anti Virus agent - Kasperski! 6. Anti Spyware agent - both signature based and behavior based! 7. Anti Phishing - since it sees the web and email traffic - it can "close the phissing loop" and verify content/url. 8. anti SPAM - based on Mailshell engine. 9. URL CAT and parental control - based on SurfControl. 10. Layer 8 agent - performs content scanning to "above layer 7" applications, AJAX, VBS, JS, etc. to detect new and unknown virus (not based on signature). 11. MLA - Multi Layer Security agent - a new invention - event correlation in REAL TIME for all event from all other modules - to drastically reduce false positive of IPS and Layer 8 agent. 12. VPN Client. These applications take 35% - 45% of PC Windows CPU. More, one cannot find a commercial implementation of all these applications in one security appliance, even when it comes to a 1U, 2U or 4U appliance. Simply, no one yet managed to integrate layer 2/3 security with layer 7 and above layer 7 content analysis. Yoggie is a unique combination of 7-8 commercial different security appliances. Why did we come with the Yoggie PICO? and why after Gatekeeper: First, we wanted to provide the experts with a 2 network ports solution: we launched the Yoggie Gatekeeper. After we came with this great invention that one can implement an *almost* identical solution using *s-route driver* at the lowest level that still NAT (yes, this is the first NAT and DHCP service inside a protected driver and in between network layers) IP address so external IP address is different from IP addresses Windows application gets. This unique implementation is the only one capable stopping attacks such as "ARP cache poisoning" - something only hardware based firewalls can do. (will go via software firewalls). We absolutely agree that Yoggie Gatekeeper using two network interfaces provides the ultimate separation and isolation but we also know that Yoggie PICO unique "S-Route driver" is by far better than software firewall. Why we didn't add network port to PICO ? - we let this choice with the Gatekeeper (for people that absolutely requires two ports) and made an alternative with almost same security level but with a much smaller form factor (easy to carry)and using the existing network port in the laptop. Your comments and suggestions are welcome. SST.
  • Hello,

    What I would like to know is how Yoggie [yoggie.com]'s devices compare to Zyxel [zyxel.com]'s ZyWALL P1 [zyxel.com]. Zyxel's device is larger at about 5×3×0.75" (assuming I'm doing the metric conversion properly) but it is a standalone device with two 10/100 Ethernet ports. Zyxel's web site says anti-virus, IDP and anti-spam will be available in the future, but since that was two years ago with no update to the web site since then, I'm guessing they will never be added, so the device only acts as a firewall with SPI
