The Week in Internet News: WhatsApp Looks to Combat the Spread of Fake News

Fake messaging: WhatsApp, the popular messaging tool, will pay researchers up to $50,000 to study the spread of fake news through its platform, notes Mashable.com. The announcement came after reports of mob lynchings in India fueled by false information spread on WhatsApp, reports the Washington Post. India’s government asked the app maker to take immediate action to stop the spread of fake news.

Defining fake news: While we’re still on the topic of fake news, Cambodia’s recent crackdown on false information is raising concerns about press freedom in the country, reports The Guardian. A new directive aimed at fake news on websites and social media allows for violators to be jailed for two years and fined US$1,000, but civil rights groups said the new rules could give “authorities the power to silence individuals at the click of a button.”

Fired by a computer: A Los Angeles worker was recently shown the door by an automated process that seemed to assume he was let go after his original manager was laid off, the BBC reports. The case could raise questions about artificial intelligence processes, but the real fix would be a more intelligent machine, The Conversation says.

Goodbye, content.ipspace.net

It turns out that while I cannot bring myself to writing or creating other content during the summer break, it feels perfectly fine to be a janitor and fix small things on the web site.

One of the long-outstanding items: get rid of the free content web site that never went where I wanted it to go… one can do only so much in 24 hours. All the features available on content.ipspace.net are now part of the main ipSpace.net web site including pointers to free content and list of free presentations.

During the summer break, I’m publishing blog posts about the projects I’m working on. Regular blog posts will return in autumn.

Backup vs. archive: Why it’s important to know the difference

If you want to make a backup person apoplectic, call an old backup an archive.It’s just shy of saying that data on a RAID array doesn’t need to be backed up. The good news is that the differences between backup and archive are quite stark and easy to understand.[ Check out AI boosts data-center availability, efficiency. Also learn what hyperconvergence is and whether you’re ready for hyperconverged storage. | For regularly scheduled insights sign up for Network World newsletters. ] What is backup? Backup is a copy of data created to restore said data in case of damage or loss. The original data is not deleted after a backup is made.To read this article in full, please click here

Using JUNOS Firewall Filters for Troubleshooting & Verification | QFX5110

The Junos firewall filter feature can be a really useful tool for troubleshooting and verification scenarios. I was recently troubleshooting a packet loss fault and I was fairly sure it was an asymmetrical routing issue but I needed a quick way of verifying. And then a colleague said, “hey, how about a firewall filter?”. Of course, assuming IP traffic, we can use a Junos firewall filter to capture specific traffic flows.

Overview

In this scenario, we have a pair of Juniper QFX5110 switches that are both connected to an upstream IP transit provider. They are also connected to a local network via a VMware NSX edge. We’re going to use a firewall filter on QFX1 and QFX2 to identify which QFX is being used for egress traffic and which QFX is being used for ingress traffic. More specifically, the flow is an ICMP flow between a host on 212.134.79.62 and Cloudflare’s DNS service.

Topology

 

Firewall Filter

So we’re essentially going to create a firewall filter to count specific egress traffic and apply as an import filter on both QFX switches. We’re also going to create another firewall filter to count the return traffic and apply Continue reading

End of term

It’s time to take my regular summer break from writing The Morning Paper – normal service will resume again on Monday 6th August. I’ll be topping up my paper backlog and scouting out interesting research during the break. If you’ve seen any great papers I haven’t already covered and that you think ‘The Morning Paper’ readers would enjoy, please do send them my way.

In the meantime, here are a few picks from papers we’ve covered this term in case you missed any of them. (In order of publication on the blog)

• Darwin – hardware/software co-design FTW.
• NetChain – blazingly fast in-network coordination service
• Beamer – rethinking the load balancer
• Semantics and complexity of GraphQL
• Measuring the tendency of CNNs to learn surface statistical irregularities
• zkLedger privacy preserving ledgers with full support for independent auditing
• DeepTest – testing tactics for DNNs (in this case, in the context of autonomous driving)
• Deep code search – joint embeddings enabling natural language queries return code snippet results
• EnclaveDB – protecting data in-memory, not just in-transit and at-rest.

Many thanks to all of you that follow along and support the blog – the accountability keeps me sticking at it when I’m snowed under, and Continue reading

Redirecting DNS Requests to Umbrella with FTD

A few days ago I shared an article that described redirecting DNS requests with ASA. A good use case for this might be if an organization is using Cisco Umbrella but there is no way to get every host is pointed toward the correct DNS server(s) in a timely manner. In that case, a configuration of destination NAT in the ASA can force those misconfigured clients to use one of the OpenDNS addresses.

This article is very similar, but we will share a method for doing this with Firepower Threat Defence. The concept is the same but all configuration is done in Firepower Management Console. Before starting on the NAT configuration, it is important to configure the following network objects (Objects, Object Management, Network).

• obj_any – 0.0.0.0/0
• Umbrella1 – 208.67.220.220
• Umbrella2 – 208.67.222.222

It is also important to confirm the existence of two port objects (Objects, Object Management, Network).

• DNS_over_TCP  –  TCP Port 53
• DNS_over_UDP –  UDP Port 53

Most of the configuration will be done on the NAT policy for the device we are managing (Device, NAT, select edit for the appropriate NAT policy).

We will need four rules that Continue reading

Our security analysis of the mobile communication standard LTE ( Long-Term Evolution, also know as 4G) on the data link layer (so called layer two) has uncovered three novel attack vectors that enable different attacks against the protocol. —David Rupprecht, Katharina Kohls, Thorsten Holz, and Christina Pöpper

To be fair, the tech sector has been the United States’ economic pride and joy in recent decades, a seemingly endless wellspring of innovation. The speed and power of Google’s search engine is breathtaking, putting extraordinary knowledge at our fingertips. Internet telephony allows friends, relatives, and co-workers to interact face to face from halfway around the world, at very modest cost. Yet, despite all this innovation, the pace of productivity growth in the broader economy remains lackluster. —Kenneth Rogoth @MarketWatch

The world of scholarly communication is broken. Giant, corporate publishers with racketeering business practices and profit margins that exceed Apple’s treat life-saving research as a private commodity to be sold at exorbitant profits. Only around 25 per cent of the global corpus of research knowledge is ‘open access’, or accessible to the public for free and without subscription, which is a real impediment to resolving major problems, such as the United Nations’ Sustainable Continue reading

Kernel of Truth episode 03 — Linux: the kernel, the community & beyond

Listen, you can’t name an open networking podcast “Kernel of Truth,” and NOT have an episode dedicated to the Linux kernel! So we got two of the brightest, most enthusiastic Linux experts we know into the recording booth and let them wax poetic about the language of the data center. As I soon found out, it’s harder to get Linux fans to STOP talking about Linux that it is to get them going — but hey, that just makes my job as host a lot easier! There’s nothing like listening to knowledgeable people discuss something they’re passionate about, and that’s what we’ve got in store for you.

In this episode, I’m joined by Roopa Prabhu, leader of the kernel team at Cumulus Networks, and Shrijeet Mukherjee, Cumulus’ former VP of Engineering. Specifically, our discussion revolves around the Linux kernel and Linux community. We get into some pretty interesting questions: why Linux in the data center? What has Cumulus contributed to the kernel? How has the prolific Linux community evolved? What the heck is a “boffin”?? I’m not a fan of spoilers, (thanks for ruining Avengers: Infinity War for me, Twitter!) so I’ll let you guys tune in and find Continue reading

NetQ is now a 2018 “New Product” Award Winner!

Cumulus NetQ is on FIRE!!

Just one year ago, Cumulus launched a new product that fundamentally changes the way organizations validate and troubleshoot not just their network, but the entire Linux ecosystem as a whole. The product was named NetQ (think Network Query). It provides deep insight on the connectivity of all network devices either now or in the past — including all switches, Linux hosts, inside Linux hosts (Containers, direct interaction with container orchestration tools like Kubernetes, VMs, Openstack environment) and any other devices running a Linux-based operating system connected to the network. No more manual box-by-box troubleshooting, no more wondering what happened last night, no more pulling cables to find where the issue was stemming from, no more finger pointing, no more human-led misconfigurations and no more frustration of not having sight past the edge of the network.

Instead, Cumulus NetQ, the agent-based technology that runs on anything Linux, changes all that. NetQ brings the efficiencies of web-scale to network operations with an algorithmic, preventive, centralized telemetry system built for the modern automated cloud network. NetQ aggregates and maintains data from across all Linux nodes in the data center in a time-series database, making the fabric-wide events, Continue reading
