Fight firewall sprawl with AlgoSec, Tufin, Skybox suites

New and innovative security tools seem to be emerging all the time, but the frontline defense for just about every network in operation today remains the trusty firewall. They aren’t perfect, but if configured correctly and working as intended, firewalls can do a solid job of blocking threats from entering a network, while restricting unauthorized traffic from leaving.To read this article in full or to leave a comment, please click here(Insider Story)

AI player AlphaGo to play Chinese Go champion

DeepMind’s AlphaGo program will test its artificial intelligence capabilities in May against top Go player Ke Jie.The match of three games in Wuzhen, China between AlphaGo and the Chinese player comes about a year after the computer program beat by 4-1 a key player, the South Korean Lee Se-dol, in a game that is regarded as involving more complex strategy than even chess.During the game, players take turns to place black or white pieces, called “stones,” on the 19-by-19 line grid. The aim is to capture the opponent's stones by surrounding them and encircling more empty space as territory. AlphaGo has been seen as a major contender because of its ability to learn from its experience, sometimes resulting in far-from-human but nevertheless successful moves.To read this article in full or to leave a comment, please click here

Linux Mint 18.1: Mostly smooth, but some sharp edges

We’ve been fond of Linux Mint for its ability to present a friendly interface to the average end user, while having a stable foundation of Debian and Ubuntu underneath. In this review, we looked at LinuxMint 18.1, dubbed Serena. We found a solid operating system that can run into problems in edge case scenarios.To read this article in full or to leave a comment, please click here(Insider Story)

Angry Shadow Brokers release password for suspected NSA hacking tools

Annoyed with the U.S. missile strike last week on an airfield in Syria, among other things, hacker group Shadow Brokers resurfaced on Saturday and released what they said was the password to files containing suspected National Security Agency tools they had earlier tried to sell.“Is appearing you are abandoning ‘your base’, ‘the movement’, and the peoples who getting you elected,” the group wrote in broken English in a letter to U.S. President Donald Trump posted online on Saturday.The hacker group, believed by some security experts to have Russian links, released in January an arsenal of tools that appeared designed to spy on Windows systems, after trying to to sell these and other supposedly Windows and Unix hacking tools for bitcoin.To read this article in full or to leave a comment, please click here

IETF 98 Report

The IETF meetings are relatively packed events lasting over a week, and it’s just not possible to attend every session. Inevitably each attendee follows their own interests and participates in Working Group sessions that are relevant and interesting to them. I do much the same when I attend IETF meetings. The IETF met for IETF 98 in Chicago at the end of March, and from the various sessions I attended here are a few personal impressions that I would like to share.

Arista gets important win over Cisco in patent battle

In yet another twist to the ongoing patent and copyright infringement case between Cisco and Arista, Arista has landed a significant win that will let it once again import redesigned products to the US that have been under import embargo since January.Specifically, according to a post on Arista’s site, on “April 7, 2017, U.S. Customs and Border Protection (“CBP”) completed its review and once again ruled that Arista’s redesigned products do not infringe the ’592, ’145, or ’537 patents that were the subject of a limited exclusion order and cease and desist order issued by the United States International Trade Commission (ITC) in Investigation No. 337-TA-944 and that Arista may resume importing its redesigned products into the United States.”To read this article in full or to leave a comment, please click here

Dallas blames hacker for setting off all 156 emergency warning sirens

Imagine it being nearly midnight and the emergency warning sirens start wailing and continue to scream for about an hour and a half. That’s what happened in Dallas on Friday; at 11:42 p.m., the city’s 156 emergency sirens blasted out warnings and continued to wail until 1:17 a.m. on Saturday. Dallas officials claim the siren warning system was hacked and it was one of the largest breaches of an emergency siren system.At first, a city spokesperson blamed the blaring sirens on a “system malfunction.” The 1.6 million people in the city were asked to stop calling 911 because there was no emergency. The normal wait time for a 911 call in Dallas is reportedly 10 seconds, but at one point the 911 system was so clogged with calls that the wait time stretched to six minutes.To read this article in full or to leave a comment, please click here

Site News: RSS Feed Update

Do to ongoing problems with RSS feed hosting from Feedblitz, I am migrating the RSS feed to a new provider on Wednesday, 12 Apr 2017.

This may cause previously ‘read’ articles in your RSS feed to show as new. Its depends on how your RSS Reader the articles as “new” and what criteria they use to detect new/read.

Apologies in advance for the inconvenience but cannot continue with the unpredictable service, poor support and low quality website that Feedblitz has delivered over the last six months.

The RSS subscription is URL is unchanged http://feeds.etherealmind.com/etherealmind which should require no changes on your part.

iPhone 8 price may be cheaper than you think

Apple's upcoming iPhone 8 is poised to be a complete game-changer. After years of keeping the iPhone form factor more or less unchanged, the iPhone 8 will likely feature an edgeless OLED display with a Touch ID sensor embedded into the screen itself. Additionally, it's widely believed that the iPhone 8 will offer up improved water resistance, faster internals, wireless charging, facial recognition software and much more.While nothing is ever a guarantee until Apple makes it official, there's good reason to believe that the iPhone 8 will represent one of the biggest leap forwards in iPhone technology we've seen in years. Having said that, there have been a number of interesting rumors regarding the iPhone 8's retail price over the past few weeks.To read this article in full or to leave a comment, please click here

Converge your network with explicit congestion notification

Every now and again, we like to highlight a piece of technology or solution featured in Cumulus Linux that we find especially useful. Priority Flow Control (PFC) and Explicit Congestion Notification (ECN) are exactly such things. In short, these technologies allow you to converge networks and save money. By supporting lossless or near lossless Ethernet, you can now run applications such as RDMA over Converged Ethernet (RoCE) or RoCEv2 over your current data center infrastructure. In this post, we’ll concentrate on the end-to-end solution for RoCEv2 – ECN and how it can help you optimize your network. We will cover PFC in a future post.

What is explicit congestion notification?

ECN is a mechanism supported by Cumulus Linux that helps provide end-to-end lossless communication between two endpoints over an IP routed network. Normally, protocols like TCP use dropped packets to indicate congestion, which then tells the sender to “slow down’. Explicit congestion notification uses this same concept, but instead of dropping packets after the queues are completely full, it notifies the receiving host that there was some congestion before the queues are completely full, thereby avoiding dropping traffic. It uses the IP layer (ECN bits in the IP TOS header) Continue reading
