Cloud security still a work in progress

A few years ago, ESG (and other) research indicated that security concerns posed the biggest impediment for more pervasive use of cloud computing. What happened next?  Business executives and CIOs found that cloud agility, flexibility and potential cost savings were too good to pass up, creating a “cloud or bust” mentality. Naturally, CISOs had to do their best and go along for the ride whether they were ready or not.+ Also on Network World: The top 12 cloud security threats + So, how’s cloud security going at this point? ESG research indicates it is still a work in progress. As part of a recent survey, cybersecurity professionals were presented with a series of statements about cloud security and asked whether they agreed or disagreed with each one. Here are some of the results:To read this article in full or to leave a comment, please click here

IDG Contributor Network: Blockchain the perfect data protection tool for banks using mainframes

Technophobic thrillers in popular media are always trying to convince us hackers are just a few malicious keystrokes away from crashing the world economy. And while doing such a thing is more complicated than just “deleting all the money,” one could certainly do a great deal of damage by changing what a computer thinks is true.Wouldn’t it be great if there were software that could guarantee which data was and was not correct, backed up by the most powerful computer processors available? I give you blockchain, which more and more fiscal institutions are using to protect their data, backed up by the undeniable power of mainframes.RELATED: Inside Bank of America's IT transformation Blockchain first entered the public’s (OK, the techie public’s) awareness in the orbit of Bitcoin, as a means of securing that controversial digital currency’s code against someone who decided to break into the right server and add a couple zeroes to their account. But Bitcoin haters need not close this tab in disgust just yet, as blockchain has come into its own as a reliable security measure for more than just black market storefronts.To read this article in full or to leave a comment, please Continue reading

US bans electronics larger than smartphones in cabins on certain flights

The U.S. Department of Homeland Security has ordered that passengers on flights departing for the U.S from 10 airports in the Middle East and Africa will have to carry personal electronics larger than a smartphone as checked baggage, citing increased terror threats.Giving the approximate size of a commonly available smartphone as a guideline for passengers, the DHS said that laptops, tablets, e-readers, cameras, portable DVD players, electronic game units larger than smartphones, and travel printers or scanners were the kind of personal electronics that would not be allowed in the cabin and would have to be carried as checked baggage.Approved medical devices may be brought into the cabin after additional screening. The size of smartphones is well understood by most passengers who fly internationally, according to the DHS, which in any case asked passengers to check with their airline if they are unsure whether their smartphone is impacted.To read this article in full or to leave a comment, please click here

Can you imagine Mars with Saturn-like rings?

It’s hard to fathom and may be even harder for it to happen but a couple NASA-funded scientists say Mars might have had Saturn-like rings around it in the past and may have them again sometime in the distant future.NASA’s Jet Propulsion Lab said Purdue University scientists David Minton and Andrew Hesselbrock developed a model that suggests debris that was pushed into space from an asteroid or other body slamming into Mars around 4.3 billion years ago alternates between becoming a planetary ring and clumping together to form a moon.More on Network World: Elon Musk’s next great adventure: Colonizing Mars+To read this article in full or to leave a comment, please click here

Russia will strike US elections again, FBI warns

Future U.S. elections may very well face more Russian attempts to interfere with the outcome, the FBI and the National Security Agency warned on Monday.“They’ll be back,” said FBI director James Comey. “They’ll be back in 2020. They may be back in 2018.”Comey made the comment during a congressional hearing on Russia’s suspected efforts to meddle with last year’s presidential election.

Pwn2Own hacking contest ends with two virtual machine escapes

Two teams of researchers managed to win the biggest bounties at this year's Pwn2Own hacking contest by escaping from the VMware Workstation virtual machine and executing code on the host operating system.Virtual machines are in used in many scenarios to create throw-away environments that pose no threat to the main operating system in case of compromise. For example, many malware researchers execute malicious code or visit compromise websites inside virtual machines to observe their behavior and contain their impact.One of the main goals of hypervisors like VMware Workstation is to create a barrier between the guest operating system that runs inside the virtual machine and the host OS where the hypervisor runs. That's why VM escape exploits are highly prized, more so than browser or OS exploits.To read this article in full or to leave a comment, please click here

Pwn2Own 2017: Your stuff as mincemeat

They came from miles around to carry out a hallowed, decade-long mission: To eat your lunch. The security researchers assembled at the Pwn2Own 2017 hacking competition, sponsored by Trend Micro, and occasionally grouped together, then performed essentially zero-day exploits (at least by the rules, heretofore unknown) on your favorite stuff, such as Windows, MacOS and Linux. Smoldering pits in the screen were left, as teams collected cash prizes and creds. RELATED: How San Diego fights off 500,000 cyberattacks a day For giggles and grins, a Type 2 Hypervisor, VMWare Workstation was also left for shrapnel, one of the first times a hypervisor has been penetrated by a virtual machine in this way. It wasn’t a cascade effect, but rather a shot across the bow. I suspect there are more ways to penetrate a foundational hypervisor, too, but they haven’t been seen in captivity to my knowledge. To read this article in full or to leave a comment, please click here

FBI looks into Russian hack of US election, possible Trump involvement

The FBI is actively investigating Russia's attempts to influence the 2016 U.S. presidential election and possible cooperation from President Donald Trump's campaign, agency director James Comey confirmed. The existence of an investigation isn't a surprise, but Comey's announcement Monday is the first time the FBI has acknowledged an active case. The FBI typically does not comment on active investigations, but the Russian actions targeting the U.S. election represents an "unusual" case, he told members of the House of Representatives Intelligence Committee. Comey told lawmakers he couldn't comment more on the investigation, but he said the FBI is looking into possible contacts and cooperation between the Trump campaign and the Russian government. The FBI is looking into "the nature of any links" between the Trump campaign and the Russian government, he said.To read this article in full or to leave a comment, please click here

Possibly the worst mass invasion of internet privacy ever

In January, a bank in Edina, Minnesota, received a request for a $28,500 wire transfer from someone claiming to be local resident Douglas Junker. Though bolstered with a faked picture of a passport, the request later turned out to be fraudulent, and local cops were reportedly stymied on how to catch the thief. Until, that is, they came up with a novel idea: Hoping to find out how the fraudster got the picture, Edina Police Detective David Lindman applied for a search warrant to obtain the names, email addresses, account information and IP addresses of everyone in the entire town of 50,000 who had searched for any variation of the victim’s name between Dec. 1, 2016, and Jan. 7, 2017. To read this article in full or to leave a comment, please click here

6 of the most effective social engineering techniques

Social engineering is the strongest method of attack against the enterprise’s weakest vulnerability, its people. Criminal hackers recognize this fact. In 2015, social engineering became the No. 1 method of attack, according to Proofpoint’s 2016 Human Factor Report.These successful social engineering methods often use phishing and malware. But deceptive information assailants have more tools and approaches to draw on than these.That’s why CSO covers six of the most effective social engineering techniques that attackers use both on and off the internet, providing insights into how each one works, what it accomplishes, and the technologies, methods, and policies for detecting and responding to social saboteurs and keeping them at bay.To read this article in full or to leave a comment, please click here(Insider Story)
