Securing Critical Infrastructure with MILS

By Paul Chen

On February 12, the White House released the Presidential Policy Directive 21 (PPD-21), Critical Infrastructure Security and Resilience. The DHS website describes PPD-21 as “advancing a national policy to strengthen and maintain secure, functioning, and resilient critical infrastructure.” Sixteen different critical infrastructure sectors are identified, including: Chemical, Communications, Energy, Financial Services, Healthcare and Public Health, Food and Agriculture, Nuclear Reactors, Transportation, and Water and Wastewater Systems.

On the same day PPD-21 was released, President Obama also signed Executive Order 13636 for “Improving Critical Infrastructure Cybersecurity.” The Executive Order directs NIST (National Institute of Standards and Technology) to develop a framework for “reducing cyber risks to critical infrastructure,” for which they have issued an RFI and plan a workshop in late May.

And on March 26, the BSI (Bundesamt für Sicherheit in der Informationstechnik, the German Federal Office for Information Security) published the Protection Profile for the Gateway of a Smart Metering System. Such devices will securely collect, process, and store information from smart meters, adding security to smart electricity distribution grids. The protection profile notes that the threat from a remote cyberattack is much higher than that from a local physical attack, since the attacker in network has the potential to compromise not just one, but many components of the infrastructure, or even the corresponding grid.

These developments highlight the focus on improving critical infrastructure security as attacks from cyber-terrorism have increased over the last decade and, alarmingly, in the past year on power, water, and nuclear systems. A recent report states that, indeed, most cyber-attacks now target critical infrastructure, moving “away from hacking and financially motivated crime” to attacks to “deny, disrupt, and destroy” service. For most of us, even the most destructive cyber-attacks like Stuxnet are fairly remote and don’t impact us; but if critical infrastructure services are denied, disrupted, or destroyed, cyber-attacks could become devastatingly personal.

Secure Mobility Message Resonates at MILCOM 2011

By Chip Downing

MILCOM 2011 last week in Baltimore, MD was not only educational, but it was a watershed event.   Last year, it was a “coming out” party for custom Android devices; this year however, was the year where many companies are now using COTS hardware and software to their fullest extent, along the entire supply chain, from core to edge and user devices.   I believe this COTS adoption is driven by two powerful forces – the exploding capabilities of commercial tablet devices, and global military budget pressures.

The vastly increasing power and capability of commercially available mobile communications devices is simply amazing. Just a few years ago, almost everything in this military communications space was purpose built, and most commercial products were simply inadequate to address the rugged and complex system demands of military communications systems.   As seen at MILCOM 2011, this has officially changed -- COTS end-to-end communications domains rule.

So if all of these MILCOM vendors are not making customized hardware and software, what are they doing?   Wind River had over 500 people visit its booth at MILCOM this year, and most of the discussions I had with both suppliers and end users at the show were about increasing device security and leveraging high volume COTS components in demanding deployment scenarios.

Improving Embedded Security: Proper Runtime Selection

By Bill Graham

Selection of secure components for an embedded system is key to a secure system. Leveraging a secure RTOS, middleware, virtualization and tools significantly reduces the effort and development costs. Moreover, there are additional benefits from using commercial-off-the-shelf (COTS) software components over Roll Your Own (RYO) code or self-ported and maintained open source code. Some of the COTS components worth considering include:

Exciting Times - Virtually!

By Chris Ault

It's an exciting time for embedded virtualization at Wind River!  We were recently named the embedded virtualization market leader by VDC Research Group.  In VDC’s 2011 ‘Virtualization for Mobile and Embedded Systems’ report, Wind River achieved the highest share of the market in 2010 with greater than 30 percent of total market revenue.

In addition to this significant recognition, today we announced updates to our embedded virtualization offering. We released updates to our guest operating systems – VxWorks and Wind River Linux, as well as updates to Wind River Hypervisor and Wind River Workbench tools.
