Starting Today: NDSS Highlights the Best in Internet Security Research

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:

The Week in Internet News: Can Blockchain Improve IoT?

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

Keeping our users safe

Keeping our users safe

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

Celebrating the 25th Anniversary of NDSS

This year we are celebrating the 25th anniversary of the Network and Distributed System Security Symposium (NDSS). NDSS is a premier academic research conference addressing a wide range of topics associated with improving trust in the Internet and its connected devices. 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 connects them together.

NDSS 2018 is about to get underway in San Diego, CA (18-21 February). It will be the biggest NDSS symposium yet, featuring 71 peer-reviewed papers, 20 posters, 4 workshops, 2 keynotes, and a co-located research group meeting. Record registration numbers are a key indicator that NDSS 2018 is featuring vital and timely topics. Below are some of the highlights expected in the coming week.

Workshops

This year’s program officially starts with four workshops on Sunday, 18 February. NDSS workshops are organized around a single topic and provide an opportunity for greater dialogue amongst researchers and practitioners in the area. Each of this year’s workshop have dynamic agendas.

The Workshop on Binary Continue reading

Workshop on Binary Analysis Research (BAR) 2018 at NDSS on 18 February

Binary analysis refers to the process where human analysts and/or automated systems scrutinize the underlying code in software to discover, exploit, and defend against malice and vulnerabilities, oftentimes without access to source code. Through protecting legacy software deployed in all types of devices and platforms in the modern world, binary analysis techniques are becoming more and more critical in making our everyday life and our society more secure.

A Workshop on Binary Analysis Research (BAR) will be co-located with the Network and Distributed System Security Symposium (NDSS), and held in San Diego, CA, USA, on February 18, 2018.

The Workshop aims to provide an interaction point for researchers doing work in binary program analysis, with half of the workshop dedicated to traditional paper sessions and the other half to a roundtable discussion among researchers, implementers, and end-users of binary analysis techniques. BAR has attracted attention of many researchers, especially tool and framework authors, who actively work to create cutting-edge techniques and build powerful tools. Here we are happy to announce that eight high-quality academic papers have been accepted to appear in the paper sessions of the workshop, with presenters from both academia and industry. Researchers and authors of several Continue reading

HTTPS or bust: Chrome’s plan to label sites as “Not Secure”

HTTPS or bust: Chrome’s plan to label sites as

Google just announced that beginning in July 2018, with the release of Chrome 68, web pages loaded without HTTPS will be marked as “not secure”.

More than half of web visitors will soon see this warning when browsing unencrypted HTTP sites, according to data from Cloudflare’s edge that shows 56.62% of desktop requests originate from Chrome. Users presented with this warning will be less likely to interact with these sites or trust their content, so it’s imperative that site operators not yet using HTTPS have a plan to do so by July.

HTTPS or bust: Chrome’s plan to label sites as

How did we get here (and why)?

To those who have followed the Chrome team’s public statements, this announcement comes as no surprise. Google has been gearing up for this change since 2014, as Chrome boss Parisa Tabriz tweeted and Chris Palmer memorialized in a widely distributed email. While this step is an important and potentially jarring one for users, it’s by no means the last step that Google will take to influence website administrator behavior for the better.

But why are they making this change (now)? Google’s primary motivation for driving HTTPS adoption is simple: a safe browsing experience is good for business. Users that feel Continue reading

Context-Aware Micro-segmentation – Remote Desktop Session Host Enhancements for VMware Horizon

In a previous post my colleague, Stijn, discussed the enhancements to how NSX for vSphere 6.4 handles Remote Desktop Session Host, RDSH, systems with the Identity-based Firewall and Context-Aware Micro-segmentation.

Remote Desktop Services 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 for vSphere 6.4 allows customers to run RDS hosts with granular security for VMware Horizon systems.

VMware Horizon 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.  In previous versions of NSX, it was not possible to individually secure user sessions and create Distributed Firewall (DFW) rule sets according to the user session logged into an RDSH server.  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 Horizon customers to follow.

Horizon allows customers Continue reading
