Singapore. Etihad. Wow. I always found it impressive when airlines were able to build a business and a brand without a significant domestic customer base to start off from. They instead focus on the global market, which is much more challenging. There is a competitive landscape of many players. There is the complexity of interconnecting a world of disparate lands and diverse customer cultures and preferences. An impressive feat.
The world of networking is becoming quite similar. From private, hybrid, and public cloud models, to increased use of SaaS, to the way SaaS and other apps are built using microservices architectures and containers, the landscape of islands to connect in an inherently secure and automated fashion is increasingly diverse and complex.
If the airline to networking analogy is lost on you, or you think it’s too much of a stretch, let me pull up the second reason I used planes in my symbolism. My brilliant colleague Yves Fauser built an app to demonstrate how NSX is connecting and securing this variety of new app frameworks, and it happens to be a “plane spotter” app. You may have already Continue reading
The Internet Society was recently approved as a Liaison Member of TF-CSIRT, the European Forum for Computer Security Incident Response Teams, and therefore took the opportunity to participate in the FIRST/TF-CSIRT Symposium that was held 5-7 February 2018 in Hamburg, Germany.
The Internet Society continues to support organisations and activities concerned with maintaining the safety, stability and security of the Internet, and our colleague Kevin Meynell is already known within the TF-CSIRT community having run the forum between 2008 and 2012 and overseen its transition from a grouping of primarily academic CSIRTs to a wider industry body encompassing more than 160 National, Government, Military and Commercial CSIRTs, as well as those in academia.
TF-CSIRT meets three times per year, but starting in 2008 the first meeting of the year has always been held jointly with FIRST, the global Forum of Incident Response and Security Teams. This provides an opportunity for the European CSIRTs to meet with their counterparts around the world to exchange information, and develop the networks of trust that are critical to effective cooperation in handling cyber incidents when they occur, but also in development of early warning and prevention techniques.
And a number of the presentations had particular Continue reading
More than half of all attacks resulted in financial damages of more than $500,000.
Got an interesting microsegmentation-focused email from one of my readers. He started with:
Since every SDDC vendor is bragging about need for microsegmentation in order to protect East West traffic and how their specific products are better compared to competition, I’d like to ask your opinion on a few quick questions.
First one: does it even make sense?
Read more ...NDSS 2018 is in full swing in San Diego this week and a couple of papers that really grabbed my attention were both in the same session on Network Security and Cellular Networks yesterday.
Samuel Jero, a PhD student at Purdue University and past IRTF Applied Networking Research Prize Winner, presented a fascinating paper on “Automated Attack Discovery in TCP Congestion Control Using a Model-guided Approach”. Of the many protocols and algorithms that are in daily use on the Internet, some are more fundamental and important than others and it doesn’t get much more fundamental and important than TCP congestion control.
TCP congestion control is what makes it possible for millions of autonomous devices and networks to seamlessly, and more-or-less fairly, share available bandwidth. Without it the network would literally collapse.
Attacks against congestion control to manipulate senders’ or receivers’ understanding of the state of the network have been known for some time. Jero and his co-authors Endadul Hoque, David Choffnes, Alan Mislove and Cristina Nita-Rotaru developed an approach using model-based testing to address the scalability challenges of previous work to automate the discovery of manipulation attacks against congestion control algorithms.
By building abstract models of several congestion Continue reading
In a previous post by my colleague, Stijn, discussed the new changes to how NSX for vSphere 6.4 handles Remote Desktop Session Host, RDSH, systems with the Identity-based Firewall and context-aware micro-segmentation.
RDSH is an underlying technology from Microsoft that many vendors take advantage of to provide overlay management and application deployment technologies for. In this post, we’re going to discuss how NSX 6.4 and the new changes to support RDSH hosts works with Citrix XenApp systems.
Citrix XenApp can provide multiple users the ability to connect to a single system to access their applications using the RDSH technology. These users can be of the same type, for example all HR users, or of multiple types, HR and Engineering users. NSX has supported User Identity based firewalling for Virtual Desktops since the 6.0 release, but it did not address RDSH in which multiple user sessions are connecting to the same host This meant less flexibility in controlling what users could access data center application servers without isolating one set of users to one RDSH server. This model created a very rigid architecture for XenApp customers to follow, which brought about the use of Continue reading
The new Trusted IoT Alliance looks at the intersection of IoT, security, and blockchain.
Network and Distributed Systems Security (NDSS) Symposium is in full swing for its 25th anniversary year. As usual the NDSS program includes a really impressive array of great content on a wide range of topics. Prior to the main event there were four one-day workshops on themes related to the topic of NDSS: Binary Analysis Research, DNS Privacy, Usable Security, and the workshop I’d like to delve into here, Distributed IoT Security and Standards (DISS).
The DISS workshop received 29 submissions and accepted 12 papers. In an interesting twist on the usual scientific workshop format, the presented papers were all still in draft form and will now be revised based on the Q&A and offline discussions that took place as a result of the workshop. Revised papers will be published by the Internet Society in due course.
Introducing proceedings, co-chair Dirk Kutscher explained that it has become evident that the success of the Internet of Things (IoT) depends on sound and usable security and privacy. Device constraints, intermittent network connectivity, the scale of deployments, economic issues all combine to create an interesting and challenging environment for the research community to address.
A decentralised approach to IoT security Continue reading
APRICOT 2018 is underway in in Kathmandu, Nepal, and as usual the Internet Society is an active participant in many areas of Asia Pacific’s largest international Internet conference. The workshops are taking place this week, with the conference happening next week. Here are some of the conference activities where we’ll be.
On Sunday, 25 February, from 18:00 to 19:00 (UTC +05:45), Aftab Siddiqui and Andrei Robachevsky will moderate a Birds of a Feather (BoF) session on routing security. From the abstract, the session will provide a space where “…operators can share their approach in securing their own infrastructure and keeping the internet routing table clean as well. Also, this will provide a platform to review and highlight various BCOP documents to address routing security.” The Mutually Agreed Norms for Routing Security (MANRS) initiative is a key piece of the routing security puzzle.
On Monday, 26 February, from 13:00 to 14:00 (UTC +05:45), Salam Yamout will be speaking at the Tech Girls Social. This session provides a space for APRICOT participants to talk and network in an open, friendly environment. The event is open to ANYONE who is interested and is not restricted to Continue reading
The digital transformation driving the adoption of multi-cloud networks requires an equivalent security transformation.
The rise of 5G and IoT devices means the threat landscape is larger than ever.
You’ve undoubtedly heard about all sorts of Internet security vulnerabilities and incidents causing harm around the world, but the flip side of all that doom and gloom is all the promising efforts underway to create a more secure, private, and trusted Internet. Starting today and going through Wednesday (18-21 February), the Network and Distributed Systems Security (NDSS) Symposium takes place to present groundbreaking research in the world of Internet security.
This year marks the 25th anniversary of NDSS, and the Internet Society is proud to have been associated with it for over 20 years now. A key focus of the Internet Society has long been improving trust in the global open Internet. In order to promote this trust, we need new and innovative ideas and research on the security and privacy of our connected devices and the Internet that brings them together. NDSS is a top tier forum for highlighting this research.
NDSS 2018 is four full days featuring:
Blockchain merges with IoT? Could Blockchain technology help the Internet of Things become more resilient? IBM thinks so. The company is exploring ways to use Blockchain to build trust between devices and to accelerate transactions on the IoT. EETimes explores the issue.
Grand Theft IoT: Someone involved in the online community for the video game, “Grand Theft Auto: San Andreas” has spun up a new botnet made up of IoT devices, according to security firm Radware. For the price of $20, the botnet can supposedly launch a 300gbps Distributed Denial of Service attack, reports Motherboard.
AI on the rise: Nearly after of all CIOs have plans to implement artificial intelligence in the future, according to a recent Gartner survey. The IT research firm recommends that companies rolling out AI projects aim low to start, and focus augmenting workers instead of replacing them, according to a story on TechRepublic.
Where the jobs are: For a time, it appeared that actual deployments of Blockchain seemed to be lagging behind the buzz. But that appears to be changing, with Blockchain developers now in high demand, TechCrunch reports. Blockchain jobs are the second fastest growing category in the labor market, with 14 job openings Continue reading
To everyone in Cloudflare, account security is one of our most important tasks. We recognize that to every customer on our platform, we are critical infrastructure. We also know that the simplest attacks often lead to the most devastating of outcomes. Most people think that if they are going to get hacked it will be by some clever ”zero day”. The reality couldn’t be farther from the truth.
Attackers are smart and they have realized that even in 2018, the human is still the weakest link in the chain. The 2017 Verizon breach report identified that 81% of hacking related breaches occurred as a result of weak credentials or credential theft, an increase from the 63% reported in 2016’s breach report.

Your credentials are as important as your house or car keys. If someone copies or steals them, the repercussions can be catastrophic. If you suspect someone has access to your house keys you change your locks. If you aren’t fast enough, someone might break in.
Likewise if you realize that someone might have access to your password, the remedy is to change it. Too often, as with house keys, we are slow to Continue reading
