IDG Contributor Network: A patchwork quilt of IoT security

The Internet of Things (IoT) presents a security threat. A key point of my last article is that manufacturers do not have the right incentives. But all is not lost. With a little ingenuity, we can make a quilt of independent pieces that can nevertheless turn out to offer good security coverage.The term “patchwork quilt” is often used pejoratively to describe something that is made up of an assortment of other parts. Yet it is worth remembering that a well-made quilt is still functional, durable and beautiful. And quilts are often made collaboratively in quilting bees. We need this sort of approach to network security.To read this article in full or to leave a comment, please click here

Why 2017 will be the worst year ever for security

Sony. Anthem. The Office of Personnel Management. Target. Yahoo. The past two years have seen one mega-breach after another—and 2017 promises to be the most catastrophic year yet.Security experts have long warned that most organizations don’t even know they’ve been breached. Attackers rely on stealth to learn about the network, find valuable information and systems, and steal what they want. Only recently have organizations improved their detection efforts and started investing the time, capital, and people needed to uncover vulnerabilities. When they do, the results are often alarming.[ 18 surprising tips for security pros. | Discover how to secure your systems with InfoWorld's Security Report newsletter. ] “I think we are going to find more, not less, breaches in 2017,” says Ray Rothrock, CEO of RedSeal, a security analytics firm.To read this article in full or to leave a comment, please click here

WhatsApp reduces spam, despite end-to-end encryption

Can a spam filter work even without reading the content of your messages?WhatsApp thinks so. Since last April, the messenger app has been successfully fighting spam abuse, even as it’s been using end-to-end encryption.That encryption means that no one -- not even WhatsApp -- can read the content of your messages, except for the recipient.More privacy, however, can raise issues about spam detection. If WhatsApp can’t scan your messages for suspicious content, say for advertisements peddling cheap Viagra, then how can it effectively filter them out?To read this article in full or to leave a comment, please click here

In treason case, Russia alleges security experts aided US

Two officers of the Russian Federal Security Service (FSB) and a cybercrime investigator from Kaspersky Lab have reportedly been charged with treason for helping U.S. intelligence services. The arrests of Ruslan Stoyanov, the head of the computer incidents investigation team at Kaspersky, and Sergei Mikhailov, the deputy head of the Information Security Center at the FSB, happened in early December and were reported in the Russian media last week. Since then, the arrest of a third FSB officer named Dmitry Dokuchayev, who also worked for the agency's Information Security Center, came to light, and the investigation is said to have targeted even more people.To read this article in full or to leave a comment, please click here

How Facebook and Google are battling internet terrorism

WASHINGTON -- Social media heavyweights like Facebook and YouTube have been working with the U.S. government and other international partners as they look to take a more active role in combating terrorist propaganda and other extremist messages that have gained traction online.Officials from the popular social network and YouTube parent Google addressed the issue here at a recent tech policy conference, where they described efforts to go beyond simply removing extremist content, and actually engaging in counter-messaging programs to present alternative narratives to those advanced by groups like ISIS."We're really focused on utilizing the strength that comes out of YouTube to push back on these messages," said Alexandria Walden, Google's counsel on free expression and human rights. "We know the power of our platform, and so we know that the best way to counter messages of hate and violence is to promote messages that push back against that, that push back against the hate and extremism and xenophobia around the world."To read this article in full or to leave a comment, please click here

Mobile security firm offers cash to hackers for their old exploits

Mobile security firm Zimperium has launched an exploit acquisition program that aims to bring undisclosed attack code for already patched vulnerabilities out in the open.Paying for old exploits might seem like a waste of money, but there are technical and business arguments to justify such an acquisition system and they ultimately have to do with the difference between exploits and vulnerabilities.A vulnerability is a software defect with potential security implications, while an exploit is the actual code that takes advantage of that bug to achieve a specific malicious goal, often by bypassing other security barriers along the way.In practice, many vulnerabilities that get reported to vendors are not accompanied by working exploits. Showing that a programming error can lead to memory corruption is typically enough for the vendor to understand its potential implications -- for example, arbitrary code execution.To read this article in full or to leave a comment, please click here

Are Apple-specific threats on the rise?

Macs are really no more secure than a PC, but for many years there just weren’t as many out there because of the expense of the hardware and other issues. They've historically been a much less popular choice among both consumers, enterprises, and hackers alike.The PC attack surface is much wider; therefore, criminals develop malware that works on PCs because the payout is much higher. James Plouffe, lead solutions architect at mobile-security company MobileIron, said there are, however, a couple of oft-overlooked things that also protect Macs.First, Plouffe said, "MacOS is actually BSD Unix derivative. Granted, it's heavily customized but this meant that, unlike Windows (which had a long tail of viruses reaching back to the days of MS-DOS), bad actors had a lot more heavy lifting to do to be able to attack macOS."To read this article in full or to leave a comment, please click here

What IT security pros are earning in 2017

Continued high demand following a record year of breachesImage by ThinkstockLast year was a record one for data breaches, with some 1,093 breaches reported. That represented a 40 percent increase over the prior year, according to the Identity Theft Resource Center. It is no wonder that information security remains one of the most top-of-mind issues for CIOs, CISOs, and CEOs. The result is continued high demand for IT security pros. “The market for IT security professionals is poised for another strong year,” notes CompTIA Senior Vice President Tim Herbert. “The security job category was one of the faster growing IT occupations during 2016. During the last 90 days, U.S. employers posted nearly 25,000 job openings for security positions.”To read this article in full or to leave a comment, please click here(Insider Story)

5 things DevOps needs to do to secure containers

Can’t we all get alongImage by PixabayDo deepening adoption and broader deployment of container technologies (from the likes of Docker, CoreOS and others) threaten to escalate into the latest skirmish between operations, developers and information security? Certainly, the potential exists to widen the rift, but in fact there is far more common ground than would initially suggest. Containerization introduces new infrastructure that operates dynamically and is open in nature, with more potential for cross-container activity. Containerization presents an almost unprecedented opportunity to embed security into the software delivery pipeline – rather than graft on security checks, container monitoring and policy for access controls as an afterthought.To read this article in full or to leave a comment, please click here

AI isn’t just for the good guys anymore

Last summer at the Black Hat cybersecurity conference, the DARPA Cyber Grand Challenge pitted automated systems against one another, trying to find weaknesses in the others' code and exploit them."This is a great example of how easily machines can find and exploit new vulnerabilities, something we'll likely see increase and become more sophisticated over time," said David Gibson, vice president of strategy and market development at Varonis Systems.His company hasn't seen any examples of hackers leveraging artificial intelligence technology or machine learning, but nobody adopts new technologies faster than the sin and hacking industries, he said.To read this article in full or to leave a comment, please click here

How to make PC security alerts better? Make them twirl, jiggle

Have you ever ignored a security alert on your PC? You’re not the only one.The warnings are designed to save us from malware infections and hacking risks, but often times we’ll neglect them. It could be because we’re too busy or we’ve seen them too many times, and we've become conditioned to dismiss them -- even the most serious ones, according to Anthony Vance, a professor at Brigham Young University.Vance has been studying the problem and he’s found that introducing certain small, but noticeable changes, can make the alerts more useful and harder to ignore.  "Our security UI (user interface) needs to be designed to be compatible with the way our brains work," he said at the USENIX Enigma 2017 conference on Tuesday. "Not against it."To read this article in full or to leave a comment, please click here
