Hardware Penetration Testing goes beyond traditional network penetration tests by directly examining physical hardware devices for vulnerabilities. It’s a more hands-on approach aimed at uncovering weaknesses that could be exploited in the physical world.
Only Software Penetration Testing isn't Enough
Modern infrastructure relies heavily on physical devices, and these devices present a surprisingly large attack surface that software testing often overlooks.
Modern devices have an ever-expanding attack surface which software often fails to recognize. Just for some examples:
- In an IoT system, whether it's the newest smart device, a medical device, or an industrial control device, a single vulnerability on any device in the system can comporomise the entire system and even devices outside the system that happen to connect at any point
- Many legacy systems are using outdated, although depending on the use case that doesn't necessarily mean it is a vulnerability risk. However, the only way to ascertain if one of these devices is a risk is to test them.
- Edge case devices are some of the devices that most frequently have security vulnerabilities, because they are developed for a single purpose with not many other considerations being taken. These vulnerabilities are often also the most limited, but it also heavily depends on the purpose of the device and what it has access to.
Adressing Problems Early
As the development of hardware devices gets closer to production ready, the amount of effort it takes to adress vulnerabilities becomes exponentially more expensive. Unlike software, which can be pretty easily modified after it has been released, the same hardware will be there for as long as the DUT is operational.
