IPv6 Security Frequently Asked Questions (FAQ)

The Internet Society recognises that global deployment of the IPv6 protocol is paramount to accommodating the growth of the Internet. Given the scale at which IPv6 must be deployed, it is also important that the possible security implications of IPv6 are well understood and considered during the design and deployment of IPv6 networks, rather than as an afterthought.

We are therefore publishing our IPv6 Security Frequently Asked Questions (FAQ), which highlights and provides answers to the most important aspects of IPv6 security.

Nvidia grabs Mellanox out from under Intel’s nose

After months of speculation, Mellanox found a suitor -- and it was a surprise, to say the least. GPU leader Nvidia snatched up the networking vendor for $6.9 billion, topping a rumored previous offer of $6 billion from Nvidia’s nemesis, Intel.The acquisition ends months of rumors of a suitor for Mellanox. Intel, Microsoft, and Xilinix were all reportedly bidding for the Israeli company, which specializes in high-speed networking. [ Read also: How to plan a software-defined data-center network ] Mellanox Technology was formed in 1999 by a former Intel executive and was a pioneer in the early adoption of InfiniBand interconnect technology, which along with its high-speed Ethernet products is now used in over half of the world’s fastest supercomputers and in many leading hyperscale data centers.To read this article in full, please click here

Connecting The Dots On Why Nvidia Is Buying Mellanox

The related but distinct HPC and AI markets gave Nvidia a taste for building systems, and it looks like the company wants to control more of the hardware and systems software stack than it currently does given that it is willing to shell out $6.9 billion – just about all of the cash it has on hand – to acquire high-end networking equipment provider and long-time partner Mellanox Technologies. …

Software-defined perimeter brings trusted access to multi-cloud applications, network resources

Many companies today have a hybrid approach to their networking and IT infrastructure. Some elements remain in an on-premise data center, while other portions have gone to the cloud and even to multi-cloud. As a result, the network perimeter is permeable and elastic. This complicates access requirements at a time when it’s more important than ever to enable accessibility while preventing unauthorized access to applications and data.To reduce risk, some organizations are applying a zero-trust strategy of “verification before trust” by incorporating stronger, stateful user and device authentication; granular access control; and enhanced segmentation no matter where the applications and resources reside.To read this article in full, please click here

Research: Practical Challenge-Response for DNS

Because the speed of DNS is so important to the performance of any connection on the ‘net, a lot of thought goes into making DNS servers fast, including optimized software that can respond to queries in milliseconds, and connecting DNS servers to the ‘net through high bandwidth links. To set the stage for massive DDoS attacks based in the DNS system, add a third point: DNS responses tend to be much larger than DNS queries. In fact, a carefully DNS response can be many times larger than the query.

To use a DNS server as an amplifier in a DDoS attack, then, the attacker sends a query to some number of publicly accessible DNS servers. The source of this query is the address of the system to be attacked. If the DNS query is carefully crafted, the attacker can send small packets that cause a number of DNS servers to send large responses to a single IP address, causing large amounts of traffic to the system under attack.
