Tunnelled IPv6 Attacks Bypass Network Intrusion Detection Systems

“The transition to internet protocol version 6 has opened up a whole new range of threat vectors that allow attackers to set up undetectable communications channels across networks, researchers have found.”
Slashdot reader Bismillah summarizes a report from IT News.

Researchers at NATO’s Cooperative Cyber Defence Centre of Excellence and Estonia’s University of Tallinn have worked out how to set up communications channels using IPv6 transition mechanisms, to exfiltrate data and for systems control over IPv4-only and dual-stack networks — without being spotted by network intrusion detection systems.

The article argues that “Since IPv6 implementations and security solutions are relatively new and untested, and systems engineers aren’t fully aware of them, the new protocol can become a network backdoor attackers can exploit undetected.” The researchers’ paper is titled “Hedgehog In The Fog.”

Intel’s Atom is underwhelming no more: New chip packs 16 cores

Intel’s Atom was mostly known as a low-end chip for mobile devices that underperformed. That may not be the case anymore.
The latest Atom C3000 chips announced on Tuesday have up to 16 cores and are more sophisticated than ever. The chips are made for storage arrays, networking equipment, and internet of things devices.[ Further reading: Intel looks to modernize data centers with new Xeon server chips ]

The new chips have features found mostly in server chips, including networking, virtualization, and error correction features.To read this article in full or to leave a comment, please click here

Switches coming out this year will drive open networking forward

Two moves by open networking vendors this week are likely to chip a little bit more off the monolith of proprietary, appliance-like equipment that still moves most packets around enterprise data centers.
On Thursday, network OS supplier Cumulus Networks introduced turnkey switches based on standard hardware from Edgecore Networks running Cumulus software. They’re designed to allow customers who are new to open networking to get started quickly and easily.
Earlier in the week, Barefoot Networks announced that Edgecore and another Taiwan-based manufacturer called WNC would start shipping switches that use the company’s fully programmable chips.To read this article in full or to leave a comment, please click here
