Worth Reading: DNS Hijacking is Real

Over the years hackers have hijacked many domain names by manipulating their DNS records to redirect visitors to malicious servers. While there’s no perfect solution to prevent such security breaches, there are actions that domain owners can take to limit the impact of these attacks on their Web services and users. —Lucisn Constantin @ The New Stack

Cybersecurity is the Top Internet Policy Concern in the Asia-Pacific Region

This month at the Asia-Pacific Regional IGF in Bangkok we will release the fourth annual Internet Society Survey Report on Internet Policy Issues in Asia-Pacific.

Findings from this year’s report show that cybersecurity, access, data protection, connectivity and privacy are the top five concerns for Internet users. These issues have more or less remained constant since 2014, however, not surprisingly this year cybersecurity has become the top issue.

Other issues that respondents expressed concern for relate to fake news, increasing digital surveillance that violates privacy rights, and more frequent instances of censorship and site-blocking that impact freedom of expression.

The History of The Wireless Field Day AirCheck

Mobility Field Day 2 just wrapped up in San Jose. It’s always a little bittersweet to see the end of a successful event. However, one thing that does bring a bit of joy to the end of the week is the knowledge that one of the best and longest running traditions at the event continues. That tradition? The Wireless/Mobility Field Day AirCheck.

The Gift That Keeps Giving

The Wireless Field Day AirCheck story starts where all stories start. The beginning. At Wireless Field Day 1 in March of 2011, I was a delegate and fresh off my first Tech Field Day event just a month before. I knew some wireless stuff and was ready to learn a lot more about site surveys and other great things. Little did I know that I was about to get something completely awesome and unexpected.

As outlined in this post, Fluke Networks held a drawing at the end of their presentation for a first-generation AirCheck handheld wireless troubleshooting tool. I was thrilled to be the winner of this tool. I took it home and immediately put it to work around my office. I found it easy to use and it provided great information Continue reading

Google finally gains traction in cloud services

Google has long run a distant third behind Amazon and Microsoft in the cloud services business, but it finally seems to be catching some momentum, if the most recent quarter is an indicator of future trajectory. During an earnings call with Wall Street analysts, Google CEO Sundar Pichai said that Google Cloud Platform continues to experience “impressive growth across products, sectors and geographies and increasingly with large enterprise customers in regulated sectors.” To be more specific, Pichai said Google closed three times as many $500,000-plus deals in the most recent quarter as it did in the same time period last year. Of course, that is kind of pointless without knowing the exact number. And given Alphabet, Google’s parent company, reported overall revenue of $25.8 billion for the quarter, it’s likely a few drops in the bucket. To read this article in full or to leave a comment, please click here

Worth Reading: IPv6 flags and DNS configuration

One of the several capabilities provided by IPv6 is that hosts are provided two options to configure their IPv6 addressles) and other parameters like the Recursive DNS Server(RDNSS) information [2]; that is either by using the stateless address autoconfiguration [3] or by obtaining the information from aDHCPv6server(4]. IPv6 hosts are advised as for the environment options by some specific flags included in the Router Advertisement (RAI messages sent by the local router(s). —ENRW (PDF)

Unix: Dealing with signals

On Unix systems, there are several ways to send signals to processes—with a kill command, with a keyboard sequence (like control-C), or through your own program (e.g., using a kill command in C). Signals are also generated by hardware exceptions such as segmentation faults and illegal instructions, timers and child process termination.But how do you know what signals a process will react to? After all, what a process is programmed to do and able to ignore is another issue.Fortunately, the /proc file system makes information about how processes handle signals (and which they block or ignore) accessible with commands like the one shown below. In this command, we’re looking at information related to the login shell for the current user, the "$$" representing the current process.To read this article in full or to leave a comment, please click here
