“If you think any of these systems are going to work as expected in wartime, you’re fooling yourself.”
That was Bruce’s response at a conference hosted by U.S. Transportation Command in 2017, after learning that their computerized logistical systems were mostly unclassified and on the internet. That may be necessary to keep in touch with civilian companies like FedEx in peacetime or when fighting terrorists or insurgents. But in a new era facing off with China or Russia, it is dangerously complacent.
Any 21st century war will include cyber operations. Weapons and support systems will be successfully attacked. Rifles and pistols won’t work properly. Drones will be hijacked midair. Boats won’t sail, or will be misdirected. Hospitals won’t function. Equipment and supplies will arrive late or not at all.
Our military systems are vulnerable. We need to face that reality by halting the purchase of insecure weapons and support systems and by incorporating the realities of offensive cyberattacks into our military planning.
Over the past decade, militaries have established cyber commands and developed cyberwar doctrine. However, much of the current discussion is about offense. Increasing our offensive capabilities without being able to secure them is like having all the best guns in the world, and then storing them in an unlocked, unguarded armory. They just won’t be stolen; they’ll be subverted.
During that same period, we’ve seen increasingly brazen cyberattacks by everyone from criminals to governments. Everything is now a computer, and those computers are vulnerable. Cars, medical devices, power plants, and fuel pipelines have all been targets. Military computers, whether they’re embedded inside weapons systems or on desktops managing the logistics of those weapons systems, are similarly vulnerable. We could see effects as stodgy as making a tank impossible to start up, or sophisticated as retargeting a missile midair.
Military software is unlikely to be any more secure than commercial software. Although sensitive military systems rely on domestically manufactured chips as part of the Trusted Foundry program, many military systems contain the same foreign chips and code that commercial systems do: just like everyone around the world uses the same mobile phones, networking equipment, and computer operating systems. For example, there has been serious concern over Chinese-made 5G networking equipment that might be used by China to install “back doors” that would allow the equipment to be controlled. This is just one of many risks to our normal civilian computer supply chains. And since military software is vulnerable to the same cyberattacks as commercial software, military supply chains have many of the same risks.
This is not speculative. A 2018 GAO report expressed concern regarding the lack of secure and patchable U.S. weapons systems. The report observed that “in operational testing, the [Department of Defense] routinely found mission-critical cyber vulnerabilities in systems that were under development, yet program officials GAO met with believed their systems were secure and discounted some test results as unrealistic.” It’s a similar attitude to corporate executives who believe that they can’t be hacked — and equally naive.
An updated GAO report from earlier this year found some improvements, but the basic problem remained: “DOD is still learning how to contract for cybersecurity in weapon systems, and selected programs we reviewed have struggled to incorporate systems’ cybersecurity requirements into contracts.” While DOD now appears aware of the issue of lack of cybersecurity requirements, they’re still not sure yet how to fix it, and in three of the five cases GAO reviewed, DOD simply chose to not include the requirements at all.
Militaries around the world are now exploiting these vulnerabilities in weapons systems to carry out operations. When Israel in 2007 bombed a Syrian nuclear reactor, the raid was preceded by what is believed to have been a cyber attack on Syrian air defenses that resulted in radar screens showing no threat as bombers zoomed overhead. In 2018, a 29-country NATO exercise, Trident Juncture, that included cyberweapons was disrupted by Russian GPS jamming. NATO does try to test cyberweapons outside such exercises, but has limited scope in doing so. In May, Jens Stoltenberg, the NATO secretary-general, said that “NATO computer systems are facing almost daily cyberattacks.”
The war of the future will not only be about explosions, but will also be about disabling the systems that make armies run. It’s not (solely) that bases will get blown up; it’s that some bases will lose power, data, and communications. It’s not that self-driving trucks will suddenly go mad and begin rolling over friendly soldiers; it’s that they’ll casually roll off roads or into water where they sit, rusting, and in need of repair. It’s not that targeting systems on guns will be retargeted to 1600 Pennsylvania Avenue; it’s that many of them could simply turn off and not turn back on again.
So, how do we prepare for this next war? First, militaries need to introduce a little anarchy into their planning. Let’s have wargames where essential systems malfunction or are subvertednot all of the time, but randomly. To help combat siloed military thinking, include some civilians as well. Allow their ideas into the room when predicting potential enemy action. And militaries need to have well-developed backup plans, for when systems are subverted. In Joe Haldeman’s 1975 science-fiction novel The Forever War, he postulated a “stasis field” that forced his space marines to rely on nothing more than Roman military technologies, like javelins. We should be thinking in the same direction.
NATO isn’t yet allowing civilians not employed by NATO or associated military contractors access to their training cyber ranges where vulnerabilities could be discovered and remediated before battlefield deployment. Last year, one of us (Tarah) was listening to a NATO briefing after the end of the 2020 Cyber Coalition exercises, and asked how she and other information security researchers could volunteer to test cyber ranges used to train its cyber incident response force. She was told that including civilians would be a “welcome thought experiment in the tabletop exercises,” but including them in reality wasn’t considered. There is a rich opportunity for improvement here, providing transparency into where improvements could be made.
Second, it’s time to take cybersecurity seriously in military procurement, from weapons systems to logistics and communications contracts. In the three year span from the original 2018 GAO report to this year’s report, cybersecurity audit compliance went from 0% to 40% (those 2 of 5 programs mentioned earlier). We need to get much better. DOD requires that its contractors and suppliers follow the Cybersecurity Maturity Model Certification process; it should abide by the same standards. Making those standards both more rigorous and mandatory would be an obvious second step.
Gone are the days when we can pretend that our technologies will work in the face of a military cyberattack. Securing our systems will make everything we buy more expensive — maybe a lot more expensive. But the alternative is no longer viable.
The future of war is cyberwar. If your weapons and systems aren’t secure, don’t even bother bringing them onto the battlefield.
