GPUs are vulnerable to side-channel attacks

Computer scientists at the University of California at Riverside have found that GPUs are vulnerable to side-channel attacks, the same kinds of exploits that have impacted Intel and AMD CPUs.Two professors and two students, one a computer science doctoral student and a post-doctoral researcher, reverse-engineered a Nvidia GPU to demonstrate three attacks on both graphics and computational stacks, as well as across them. The researchers believe these are the first reported side-channel attacks on GPUs.[ Read also: What are the Meltdown and Spectre exploits? | Get regularly scheduled insights: Sign up for Network World newsletters ] A side-channel attack is one where the attacker uses how a technology operates, in this case a GPU, rather than a bug or flaw in the code. It takes advantage of how the processor is designed and exploits it in ways the designers hadn’t thought of.To read this article in full, please click here

Android does not support DHCPv6 and Google ‘Won’t Fix’ that

Android does not support DHCPv6 and Google 'Won't Fix' that

Since 2012 there has been a ticket open on Google's public 'Issue Tracker' requesting Android support DHCPv6. On 6th November the status of the issue was changed to 'Won't Fix (Intended Behavior)'.

The fact that Android does not support DHCPv6 may come as something of a surprise to those network engineers more familiar with IPv4. DHCP is a keystone of IP networks, one piece of network automation that has been widely adopted for years, and an important source of auditing by storing the IP and MAC address combination at the server.

Autoconfig baked-in

But hang on you 32-bit wranglers, we are talking v6 here and that protocol has host address generation baked in, in the form of Stateless Address Autoconfiguration, or SLAAC. In the v6 world, the local gateway acts as vital source of information for the attached end clients, issuing periodic Router Advertisements, or RAs. These advertisements can contain the local prefix, and if that is a /64 with the 'A' flag set, the end client can generate its own address; using the /64 as the network portion and making up the other 64 bits itself. Moreover, it allows clients to generate multiple, temporary prefixes to help prevent attacks Continue reading

We Won’t Save the Internet by Breaking It

On the anniversary of the armistice ending the First World War, more than 40 countries stood together for security online by signing the Paris Call for Trust and Security in Cyberspace. The call, which sets out a list of challenges the world needs to tackle, seems to be promising on paper. From hacking to harming the public core – all of this needs to be addressed. And it needs to be addressed urgently.

Others signed the call too. The Internet Society signed because we believe it is a continuation of calls we have made before. It maintains that solutions to Internet issues must be developed together with other Internet stakeholders – each performing its role, and all working collaboratively.

This approach is what allows the Internet to thrive and is key to the ultimate success of this call. Open, decentralized, and distributed. It’s not the traditional multilateral way of doing things, but it is the Internet way – the only one that can work.

There are real and pressing Internet security concerns. It’s critical that signatories to the call do not imagine they can address the concerns alone. The Internet depends, as a technical fact, on cooperative voluntary action, so Continue reading
