SD-WAN: What it is and why you’ll use it one day

Managing the Wide Area Network (WAN) for Redmond Inc., a supplier of industrial and commercial products – from salt that’s used to protect winter roadways to organic dairy products and health items – is an easier job today for the company’s technical project manager Aaron Gabrielson than it was a year ago.Redmond manages a phone system, point of sale and fax centrally out of headquarters in Heber City, Utah, which means each of Redmond’s 10 branch sites across the Midwest need a reliable connection back to headquarters in Utah. That’s easier for some sites, like those in Salt Lake City, than others, such as rural areas where there may only be a handful of workers on a farm.To read this article in full or to leave a comment, please click here

So, You Want To Be A Manager

And so it was as a young man that I aspired to be a manager. Management looked like control to me. After all, I thought that as I acquired technical expertise in operating systems, security, and networking, I should be the one holding the reins. That’s logical, perhaps. But it’s naive.

Bill filed in Congress would ban encryption backdoors

Four Congressmen are proposing that states be forbidden to ask manufacturers to install encryption backdoors on their products outfitted with the technology. U.S. Rep.

Blake Farenthold (R-Texas), Suzan DelBene (D-Wash.) and Mike Bishop (R-Mich.).To read this article in full or to leave a comment, please click here

U.S. intelligence chief touts IoT as a spying opportunity

In a brief aside during a Senate testimony on overall national security this week, U.S. director of national intelligence James Clapper justified the privacy and security advocates who have warned of the implications of the Internet of Things (IoT) since before it was a buzzword."In the future, intelligence services might use the [Internet of Things] for identification, surveillance, monitoring, location tracking, and targeting for recruitment, or to gain access to networks or user credentials," Clapper said, according to The Guardian.To read this article in full or to leave a comment, please click here

Underhanded C contest winner’s code fools nuke inspectors into destroying fake nukes

What if Alice and Bob represented countries that agreed to a nuclear disarmament treaty, but neither trusted the other enough to scan a warhead and observe the test results because the scans revealed sensitive information about their nuclear program? In the end, the countries agree to build a fissile material detector that would output only a “yes” or “no” as to if each country dismantled real warheads and not fakes.In essence, that was the scenario for the annual Underhanded C Contest which tasked programmers with solving “a simple data processing problem by writing innocent-looking C code, while covertly implementing a malicious function. This type of malicious program, in the real world, could let states take credit for disarmament without actually disarming.”To read this article in full or to leave a comment, please click here

IDG Contributor Network: Drugs, guns, and hitmen more common on dark web than religious extremism

What many of us likely suspected, but possibly hadn't gone to the trouble—or had the inclination—of finding out for ourselves is that the dark web is full of illegal and dubious stuff, researchers have found. The researchers, who have been studying and writing about encryption policy, sniffed around with a Tor browser and found 1,547 out of 5,205 total websites live on the dark web engaging in illegal activity. Those illicit destinations, uncovered in early 2015, covered subjects relating to illegal drugs, money laundering, and "illegitimate" pornography, the Kings College London scientists write in their Cryptopolitik and the Darknet paper abstracted in Survival: Global Policy and Strategy, a journal.To read this article in full or to leave a comment, please click here

SAP slaps patch on leaky factory software

SAP's February round of critical software updates includes one for SAP Manufacturing Integration and Intelligence (xMII) that may be of interest to hackers and spies. The software is widely used in manufacturing industry, where it connects factory-floor systems to business applications for performance monitoring -- but a flaw in it meant that restrictions on who could see what were not enforced. The patch for xMII fixes a directory traversal vulnerability, SAP reported Tuesday in security note 2230978. The vulnerability could have allowed attackers to access arbitrary files and directories on an SAP fileserver, including application source code, configuration and system files and other critical technical and business-related information, security researchers at ERPScan said Wednesday.To read this article in full or to leave a comment, please click here
