The Boeing Company is pioneering a way to securely bring together business IT networks with what ordinarily are entirely separate networks for industrial-control systems (ICS) in order to gain efficiencies and benefits in information-sharing in manufacturing.

An experiment in which a Trend Micro researcher set up two instances of an Internet-based simulation of an industrial-control system (ICS) for a nonexistent water-pump facility in rural Missouri found the simulated system was targeted 17 times over about four months in ways that would have been catastrophic if it had been a real waterworks operation.

Google is working out any bugs in the latest update to the Android mobile operating system before releasing it broadly, and that's good news for Samsung Nexus S users.

If a cyberattack from a hostile foreign source ever hit a public electric or water utility, affecting its industrial control systems, causing America's critical infrastructures to fail, would we understand that had even happened? We have more doubts than ever, after every twist and turn in the saga that began with the Nov. 10 "Public Water District Cyber Intrusion" report from the Illinois Statewide Terrorism & Intelligence Center (STIC) that set off a media firestorm after the report was leaked to the media.

If nothing else, the now disputed "hacking" of an Illinois water utility has brought the spotlight back to shine on the vulnerability of our national infrastructure.

As new information about Duqu continues to come out, some experts are starting to question whether the danger posed by the trojan has been exaggerated.

Efforts to strengthen critical infrastructure targets continue to focus on front-end systems rather than on underlying industrial control systems where the real problems exist, security experts warned this week.

Files entrusted to cloud-storage provider Dropbox were susceptible to unauthorized access via three attacks devised by security researchers, but the provider has since closed the vulnerabilities.
