Trailrunner7 writes with news of the continuing poor state of security for industrial control systems. From the article: "Never underestimate what you can do with a healthy list of advanced operator search terms and a beer budget. That's mostly what comprises the arsenal of two critical infrastructure protection specialists who have spent close to nine months trying to paint a picture of the number of Internet-facing devices linked to critical infrastructure in the United States. It's not a pretty picture. The duo ... have with some help from the Department of Homeland Security (PDF) pared down an initial list of 500,000 devices to 7,200, many of which contain online login interfaces with little more than a default password standing between an attacker and potential havoc. DHS has done outreach to the affected asset owners, yet these tides turn slowly and progress has been slow in remedying many of those weaknesses. ...The pair found not only devices used for critical infrastructure such as energy, water and other utilities, but also SCADA devices for HVAC systems, building automation control systems, large mining trucks, traffic control systems, red-light cameras and even crematoriums."

      Part of the problem is the engineers designing them. They don't understand the sandbox they're playing in. It isn't in their culture and they don't know that they should secure them much less how to. I'm starting to see organizations hire product security engineers now to try and institute this stuff into the products but they seem way behind the curve IMHO.

        The thing with security is... outside of the curve, there's outside-the-box thinking, comprehension and competence that are involved. You're trying to outsmart potentional attackers, not follow a white paper that they have access to. "Behind the curve" is false because there is no curve, there's just secure and insecure practices. The exploit will either work, or it won't. This only applies at the application level btw.

        Two factors have caused this - one, the assumption that those with the knowledge to cause havok have better things to do with their time, and two, the assumption by manufacturers that factory floor equipment will be physically seperated from the public (and by implication, the Internet).

        All the changes that have resulted in this situation or probably very recent (10 years), and are in situations where legacy networks and equipment have been bolstered by or re-connected with new stuff by young IT-types, not engineers, who probably had no idea all the industrial stuff wasn't secured!

        Don't blame me, I'm just the guy that wrote the specification and the software.

        - Management told me to remove security. Too much effort (what's a linter? Stop using it. Shorter passwords. Private network? Can't we just use a cable modem? "Fuzzing" ? Takes too long... turn it off)
        - Management told me to remove encryption. Too hard to read and debug over-the-wire for the field tech, who might have to run a program and click a button to decode traffic. Or worse, move a jumper to "debug".
        - Management had me source the cheapest possible components, and try to use software to recover from their faster and bizarre failures.
        - Management had me install DHCP support into the SCADA devices, so it could be hooked onto the easiest possible network.
        - Management had me unlock the cellular modem so it would connect to any tower.
        - Management had me use public DNS in my SCADA system, because running our own would have cost an afternoon.
        - Management had me write a 4 digit backdoor PIN into all hardware, that could not be turned off.
        - Management had me specify, design, and write a remote firmware flash interface supporting and utilizing most of the above.
        - Management had me write a remote reverse serial console proxy available by pointing your web browser at the right URL.
        - Management had me use public rdate servers rather than pay for an accurate internal clock.

        Look, I'm just a software engineer. I know a bit of hardware. I let people know when things are dangerous. I quote them times and estimates and costs.

        I quote them expected failure rates.

        They settle on the cheapest most disease-ridden stray cat they can find starving in a ditch and sell it as a liger. And your engineers somehow buy it.

        As a SCADA/Integration guy, I can say that most controls engineers cringe at the thought of their networks being open to the internet. It's usually managers and bean counters who demand real-time global data reporting who drive this lunacy. It's not as simple as it appears.

        • by tzanger (1575)

          I've lived in the industrial controls world for quite a while before striking it out on my own... "real-time global data reporting" doesn't require a world-accessible control interface, or even an open internet connection. It's much simpler than you're making it out to be. Hell a basic VPN connection back to HQ that puts the remote sites on the corp LAN (where all the data aggregation can take place and be accessed for "dashboards" and whatnot) would be a major step up.

      • by Anonymous Coward on Friday January 11, 2013 @12:01AM (#42554557)

        I worked as a Controls Engineer for 6 years designing, installing, and commissioning PLC / SCADA systems. The clients were anything from large steel mills, manufacturing plants, government, and even propulsion systems for naval vessels. My company was contracted to install these systems and sometimes train the customer's personnel to then handle problems or make additions to the control system if necessary.

        The personnel were more often than not your normal plant electricians and if we were lucky an actual engineer, but usually not one with much IT ability. Today's controls systems almost always have a normal Ethernet network sometimes utilizing commercial OTS network switches. This is a big change from 10-15 years ago when the communication media was mostly proprietary for control networks.

        When a problem arose I've seen these guys just unplug and plug in CAT5E Cale's wildly in the hopes of rectifying a problem that brought a process line or machine to a hault without much thought as to where the issue lies. Other times the plant manager will want to view the SCADA data from his office so he will instruct an employee to just bridge the control network to the business / office network.

        It's really not the fault of the people designing the systems. In the end the company that owns it takes the blame. The vast majority of customers will not pay extra to have their employees trained on these systems and I've never seen one concerned with security. My company sent me to Certified Ethical Hacking training in order to try and make our systems more secure, but in the end the systems integrator's hands are tied.

It's a problem, and it's being addressed, but as the submission states there's a huge lag time with huge companies, so it'll continue to be a problem for a while.

        Very insightful but the problem is worse than just the merging of mech/network engineering within a single company. There is a sea of dysfunction washing over the different companies, systems, processes, players and roles. There is a big mess to clean up and although it galls me to say so, I think some sort of legislation may be required both in terms of setting standards and of assigning accountability for poor systems. I won't hold my breath waiting for help on this side.

        Some stuff I know to be true:

        - CEOs & CFOs are motivated by share price and stock performance issues; they consider IT infrastructure to be an expense item to be minimized. Security devices are cheap but no in house expertise is fostered, and external advice may be poor or ignored if it leads to inconvenient costs. Truck drivers and drag-line operators are valued positions at a mining company because what they do generates income and income to cost is readily calculated; network designers and IT security admins are just an expense item to be minimized. They generate no obvious positive monetary benefit. More trucks/draglines/drivers/operaters = more income and more profit. More IT people = less profit.

        - Equipment vendors may be experts at their specific technology but the control programs are not part of their core knowledge. An example I have seen: although the vendor uses some robust logic controllers in the system, they all tie back to a custom control layer built originally by a summer co-op student for a lab demo. The control program does have login security but has never been through any sort of security audit. All system functionality funnels through this layer. It does have a beautiful presentation layer built by a contract software house. BTW, although the login has some protection, by default there is a network API that is always wide open and can not be shut off or everything crashes. No one knows why. If Production Company A buys production equipment from Vendor Company B, the security vulnerabilities are provided at no extra charge. None of the security issues are documented by B (they largely don't know they exist) and B has no good advice to offer on security issues in any case. The sales droids typically say security is not an issue and their track record speaks for itself. No serious events must mean the product is great.

        - Even if production security is seen to be an area of need, corp culture and politics keep anything meaningful from happening. The IT expertise that a company does have is usually focused on internal desktop and financial/HR security issues. They know nothing of the SCADA world which marries physical devices to the abstract world of networks and computing. Worse, the IT division (complete with VP or EVP) views any use of computers and networks outside of the corporate LAN to be a threat to the corporate well being. The IT division sees the production network as a threat to the corporate LAN (usually the threat is worse in the other direction!) so production must run outside the corporate firewalls. This is ok, but IT management actively undermines development of a production side IT division as that is a threat to the corp. power structure. Production networks are built and run by engineers who are smart and have a side interest in computing but whose areas of expertise are power control or chemical production or mechanical systems.

        - There is no widely accepted set of standards for production network design and deployment. Production network implementers invent the wheel again and a
