FAQ: What's so special about 802.11ad Wi-Fi?
Here are the broad strokes about 802.11ad, the wireless technology that’s just starting to hit the market.

2.5 and 5 Gigabit Ethernet Now Official Standards
In 2014, multiple groups started efforts to create new mid-tier Ethernet speeds with the NBASE-T Alliance starting in October 2014 and MGBASE-T Alliance getting started a few months later in December 2014. While those groups started out on different paths, the final 802.3bz standard represents a unified protocol that is interoperable across multiple vendors.
The promise of 2.5 and 5 Gbps Ethernet is that they can work over existing Cat5 cabling, which to date has only been able to support 1 Gbps. Now with the 802.3bz standard, organizations do not need to rip and replace cabling to get Ethernet that is up to five times faster.
"Now, the 1000BASE-T uplink from the wireless to wired network is no longer sufficient, and users are searching for ways to tap into higher data rates without having to overhaul the 70 billion meters of Cat5e / Cat6 wiring already sold," David Chalupsky, board of directors of the Ethernet Alliance and Intel principal engineer, said in a statement. "IEEE 802.3bz is an elegant solution that not only addresses the demand for faster access to rapidly rising data volumes, but also capitalizes on previous infrastructure investments, thereby extending their life and maximizing value."

A quick fix for stupid password reset questions
It didn’t take 500 million hacked Yahoo accounts to make me hate, hate, hate password reset questions (otherwise known as knowledge-based authentication or KBA). It didn't help when I heard that password reset questions and answers -- which are often identical, required, and reused on other websites -- were compromised in that massive hack, too.
Is there any security person or respected security guidance that likes them? They are so last century. What is your mother’s maiden name? What is your favorite color? What was your first pet’s name?

French hosting provider hit by DDoS close to 1TBps
A hosting provider in France has been hit by a distributed denial of service attack that went close to one terabyte per second.
Concurrent attacks against OVH clocked in at 990GBps.
The attack vector is said to be the same Internet-of-Things botnet of 152,464 devices that brought down the website of security expert Brian Krebs.
OVH chief technology officer Octave Klaba tweeted that the network was capable of attacks up to 1.5TBps.

Latest IoT DDoS Attack Dwarfs Krebs Takedown At Nearly 1Tbps Driven By 150K Devices
If you thought that the massive DDoS attack earlier this month on Brian Krebs’ security blog was record-breaking, take a look at what just happened to France-based hosting provider OVH. OVH was the victim of a wide-scale DDoS attack that was carried via network of over 152,000 IoT devices.
According to OVH founder and CTO Octave Klaba, the DDoS attack reached nearly 1 Tbps at its peak. Of those IoT devices participating in the DDoS attack, they were primarily comprised of CCTV cameras and DVRs. Many of these types devices' network settings are improperly configured, which leaves them ripe for the picking for hackers that would love to use them to carry our destructive attacks.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
