While there are a multitude of ways to hack into any given system, MEMS (micro electro-mechanical systems) and sensors are especially vulnerable to attack. The attributes that make them so cheap and powerful also make them difficult to secure: they are tiny, have limited processing power, and offer little physical room for memory or additional computing.
And they're ubiquitous. Mitre Corp.’s principal cyber security engineer Cynthia Wright explained, In homes and offices, we find MEMS and sensors in air-quality alert and fire-detection systems. In cars and trucks, they enable vehicle airbag-crash sensors, tire pressure monitoring systems, collision avoidance and a multitude of other safety functions. In medical wearables, they monitor blood glucose levels, heartrate and other biological functions. We use them for insulin delivery and for neural, cochlear and retinal implants. They are integral to prosthetic arms and limbs.
MEMS and sensors also play a role in critical infrastructure such as power plants and transportation systems,” said Wright, a retired military officer with over 25 years of experience in national security and cyber strategy and policy. She added that they are widely deployed in military applications such as battlefield robots and exoskeletons, bomb bots for defusing ordinance, and laser tuning for communications and satellites.
Although these MEMS- and sensors-enabled systems are incredibly diverse, they have one thing in common: their wireless connectivity — the conduit through which they become vulnerable. Despite these challenges of connectivity and capacity, the MEMS and sensors industry can improve the cybersecurity of connected electronics.
Carmelo Sansone, director, SEMI-MEMS & Sensors Industry Group (MSIG), sees this challenge as an opportunity for MEMS and sensors suppliers. Suppliers don’t need to reinvent themselves to secure wirelessly connected electronic products,” said Sansone. They do need to fearlessly explore potential vulnerabilities in order to address them, and they need to decide which types of devices warrant added security.”

Many of these mismatch problems were supposed to wither away with the introduction of the USB connector as a universal DC connector. That was a good idea, but you can’t stop progress and the need for ever-smaller, thinner connectors as well as higher-current connectors. So, USB now has its own wide family of incompatible connectors — just like the barrel family, Figure 3 and Reference .
It seems to me that the idea of a universal connector is based on wishful thinking. User and product needs change and advance, there are unexpected developments in technology, and stuff happens. Look at it this way: if you have a connector-interface problem, someone else has likely already had it and there’s (hopefully) a commercial adapter available.
Perhaps the best thing to do is be prepared with a stock of adapter connectors and cables, and also know a website or retail store that carries a comprehensive selection. With today’s connectors and wires, it’s not like back in the day” when connectors and their wires (including barrel types) were large enough that you could even take two cables with suitable connectors and hand-splice and solder them together — that’s generally not a practical option now.
What has been your most frustrating cable/connector mismatch problem? Did you have to improvise a solution on the spot, or go out and try to find (or order) the right adapter?
