IC Security Threat Grows As More Devices Are Connected

/in


Designing for security is beginning to gain traction across a wider swath of chips and systems as more of them are connected to the Internet and to each other, sometimes in safety- and mission-critical markets where the impact of a cyber attack can be devastating.

But it’s also becoming more difficult to design security into these systems. Unlike in the past, connectivity is now considered essential to functionality. And rather than a single chip, many of these devices are now multi-chip implementations with multiple layers of connectivity used for updates and communication within a system or between systems. Identifying security holes is becoming much harder, and plugging them sometimes requires the cooperation of multiple vendors.

“We’re connected now with everything,” said Dana Neustadter, DesignWare security IP product marketing manager at Synopsys. “Even a sensor could be connected through the Internet, and then it can open yet another attack surface. And we’ve been talking about AI for all the good reasons, but AI can also be used to more efficiently break the system. As technology evolves, data becomes more important, and we see more attacks. It’s a continuum, and security has been part of that for a while. But in the past, security was at the end of the chip design process. That was okay then, but not today. The pressure is much higher, and the risks are much more serious.”

Those concerns are echoing across the semiconductor supply chain these days as the number of connected devices continues to explode.

“What’s different is the number of IoT devices,” said Andreas Kuehlmann, CEO at Tortuga Logic. “IoT devices are traditionally not the most expensive devices. The margins on these devices are very low, and as a result security is treated like as an option, if it’s there at all. The problem with security fundamentally comes down to the weakest link. Hackers string vulnerabilities together. They just need to find one — maybe on a chip, maybe in software, another one maybe on the chip, maybe in software, and so on. Then they can string an attack together.”

Most people are aware when an IoT device is connected to the Internet. What they…

Cybercriminals get bolder as impact from SolarWinds and ransomware grows

/in


In 2006, then-U.S. Senator Barack Obama published a book, “The Audacity of Hope,” on his way to winning the White House in 2008. If the cybersecurity community were to write a similar treatise today, the appropriate title would most likely be “The Audacity of Hacks.”

FireEye Inc. held a series of sessions this month to offer a “state of cybersecurity” picture timed with the release of its Mandiant M-Trends 2021 report. One conclusion from the sessions and the report’s findings is that nation states and cybercriminals have become increasingly emboldened over the past year. Hacking has morphed from annoyance and inconvenience into extortion and social disruption on a global scale.

FireEye itself received confirmation of the perilous state of cybersecurity in December when the firm realized that hackers managed to steal its closely guarded Red Team assessment tools used to test customer security. The company’s analysis of how a portion of its crown jewels could be breached led to the discovery of what is now known as the SolarWinds exploit, a sophisticated malware campaign which allowed hackers to infiltrate systems involving at least 100 private companies and multiple U.S. government agencies.

The breach, which reflected extraordinary tradecraft and sophistication according to FireEye, is believed to have been led by the Russian government. The audacious hack has captured the attention of security analysts and government officials around the world, and it has set the stage for what may well be a rocky year ahead.

“What’s different now is the audacity that nation states are using, against a backdrop of a global pandemic,” Sandra Joyce, executive vice president and head of global intelligence at FireEye Mandiant, said during one of the company’s sessions this month. “For everything we see nation states do, the cybercriminals are carefully watching.”

Dwell times decrease

This year’s Mandiant report offered a mix of good news and bad. On the positive side, 59% of security incident investigations by the firm were initially detected by its customers, a 12% increase over the previous year.

In addition, global median dwell time or the duration…
