Why dynamic mapping is changing network troubleshooting for the better

Effective network troubleshooting requires experience and a detailed understanding of a network’s design. And while many great network engineers possess both qualities, they still face the daunting challenge of manual data collection and analysis.The storage and backup industries have long been automated, yet, for the most part, automation has alluded the network, forcing engineering teams to troubleshoot and map networks manually. Estimates from a NetBrain poll indicate that network engineers spend 80% of their troubleshooting time collecting data and only 20% analyzing it. With the cost of downtime only getting more expensive, an opportunity to significantly reduce the time spent collecting data is critical.To read this article in full or to leave a comment, please click here

How to use blockchain: Following an asset through its lifecycle to learn more

This contributed piece has been edited and approved by Network World editorsPossession is nine-tenths of the law, right?  But thanks to blockchain, this old adage may no longer be a viable way to settle property disputes.Artists and enterprises alike have long struggled to prove ownership of their work after it has been disseminated, especially when it is uploaded online. What if there was a way to use technology to reliably track asset provenance with absolute certainty, from creation to marketplace and beyond?  The reality is that this is already possible with the help of blockchain, and the benefits to the enterprise are many.To read this article in full or to leave a comment, please click here

12 ways to improve run-time container security

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.There still really aren’t many enterprise run-time security tools for containers available, which has skewed the conversation toward establishing defensive barriers prior to run-time – during the build, integration, and deployment stage.Of course, with rapidly evolving technology like containers, it can be all too easy to overlook the most basic security concerns, so, really, any focus at all is welcome. Efforts pointing out the security advantages of digitally signing container images at build time, and scanning them before they are pushed to the registry, should indeed be heard. The OS should be hardened and attack surfaces should be trimmed where possible. Solutions like Seccomp and AppArmor that introduce security profiles between containers and the host kernel ought to be implemented.To read this article in full or to leave a comment, please click here

6 Tips for Protecting Against Ransomware

The Internet Society has been closely monitoring the ransomware cyber-attacks that have been occurring over the last couple of days. The malware, which has gone by multiple names, including WannaCry, WannaDecryptor, and WannaCrypt, exploits a flaw in Microsoft Windows that was first reportedly discovered by the National Security Agency (NSA). A group of hackers leaked the code for exploiting this vulnerability earlier this year, and a fix or patch was available as far back as March 2017. Since Friday, 200,000 computers in 150 countries have been compromised using this exploit. The numbers are expected to grow exponentially as people settle back into their work routines and regular use of computer systems this week.

Security-as-a-service supplier Alert Logic started with IDS and blossomed from there

Gray Hall, CEO of Alert Logic, cut his teeth delivering enterprise-class services when he started VeriCenter, one of the earliest managed hosting companies.  Hall eventually sold that company to SunGard Data Systems in 2007, and in 2009 joined Alert Logic where he has since driven revenue growth 12x.  Network World Editor in Chief John Dix recently caught up with Hall to learn more about Alert Logic and the security-as-a-service movement.Lets start with a brief background on the company.Alert Logic was founded in 2002 -- the founders are still with us today in very key roles – and the original vision was to bring together SaaS and managed security services, starting with Intrusion Detection Systems (IDS). Sourcefire had been around for a long time, they were the gorilla in the space (now owned by Cisco), but Sourcefire is a very advanced product and most of our customers would say it’s expensive, complex, and you need a lot of expertise to make it work.  It’s only as good as the content you feed it and once you reconfigure your network, you have to do it all over again … tuning, configuration, etc.To read this article in full Continue reading

After revolutionizing the music industry, the MP3 is officially dead

The MP3 file format, the one that helped the iPod become a mainstream and iconic device, is now officially dead.According to a new report via NPR, the Fraunhofer Institute for Integrated Circuits has stopped providing licenses for MP3 technology, noting that more superior audio formats have rendered the MP3 obsolete. Speaking to NPR, the Fraunhofer Institute said AAC has since become the "de facto standard for music download and videos on mobile phones."A statement on the matter reads: We thank all of our licensees for their great support in making mp3 the de facto audio codec in the world, during the past two decades.To read this article in full or to leave a comment, please click here

Building Linux-powered devices, part 1: Making my Linux-only world a reality

Sometimes, if you want something badly enough, you need to get off your lazy tuchus and make it happen yourself. For years now, I've been hoping and pining (and often complaining and whining) about how much I want Linux-powered... everything. Not Android. Not ChromeOS. Real Linux. The kind of Linux you have full control over—the sort you'd install on your desktop PC. And when I say "everything," I mean everything. The set-top box connected to my TV. My game consoles (including handheld game consoles). Tablets. PDAs. Home server. The works. All of it. Running Linux and free software. To read this article in full or to leave a comment, please click here

How to make Fully Homomorphic Encryption “practical and usable”

Fully Homomorphic Encryption (FHE) for years has been a promising approach to protecting data while it’s being computed on, but making it fast enough and easy enough to use has been a challenge.The Intelligence Advanced Research Projects Activity, which has been leading the Department of Defense’s examination of this topic, recently awarded research and development firm Galois a $1M contract to explore ways to bring FHE to programmers. The goal, says Galois Principal Investigator Dr. David Archer, is making FHE “practical and usable,” and his outfit is working with researchers at the New Jersey Institute of Technology on this front via the Rapid Machine-learning Processing Applications and Reconfigurable Targeting of Security (RAMPARTS) initiative. To read this article in full or to leave a comment, please click here
