Tech Companies Endorse MANRS Routing Security Actions

A coalition of more than 40 companies focused on protecting online users has endorsed a global community initiative, coordinated by the Internet Society, to improve the security of the Internet’s routing system.

The Cybersecurity Tech Accord, whose members include Facebook, Microsoft, Oracle, and Hewlett Packard Enterprise, will support the Mutually Agreed Norms for Routing Security (MANRS) initiative.

The goal of MANRS is to ensure a secure and resilient Internet by protecting its routing infrastructure. In 2017 alone, more than 14,000 routing outages or attacks – such as hijacking, leaks, or spoofing – resulted in stolen data, lost revenue, and reputational damage.

“The new endorsement is a good first step,” said Salam Yamout, Internet Society Lead for the MANRS initiative.

“It is not enough to talk about routing security; it is time for action,” Yamout added. “Because the Internet’s routing system was built on the principles of collaboration and shared responsibility, this endorsement from the Cybersecurity Tech Accord and our new partnership is a major step forward. It clearly reflects the will of industry to be proactive in implementing safe routing practices.”

MANRS focuses on four defensive actions that can reduce the most common routing threats:

The rise of next-generation network packet brokers

Network packet brokers (NPB) have played a key role in helping organizations manage their management and security tools. The tool space has exploded, and there is literally a tool for almost everything. Cybersecurity, probes, network performance management, forensics, application performance, and other tools have become highly specialized, causing companies to experience something called “tool sprawl” where connecting a large number of tools into the infrastructure creates a big complex mesh of connections.Ideally, every tool would receive information from every network device, enabling it to have a complete view of what’s happening, who is accessing what, where they are coming in from, and when events occurred.To read this article in full, please click here

Optimising Caching on Pwned Passwords (with Workers)

Optimising Caching on Pwned Passwords (with Workers)

In February, Troy Hunt unveiled Pwned Passwords v2. Containing over half a billion real world leaked passwords, this database provides a vital tool for correcting the course of how the industry combats modern threats against password security.

In supporting this project; I built a k-Anonymity model to add a layer of security to performed queries. This model allows for enhanced caching by mapping multiple leaked password hashes to a single hash prefix and additionally being performed in a deterministic HTTP-friendly way (which allows caching whereas other implementations of Private Set Intersection require a degree of randomness).

Since launch, PwnedPasswords, using this anonymity model and delivered by Cloudflare, has been implemented in a widespread way across a wide variety of platforms - from site like EVE Online and Kogan to tools like 1Password and Okta's PassProtect. The anonymity model is also used by Firefox Monitor when checking if an email is in a data breach.

Since it has been adopted, Troy has tweeted out about the high cache hit ratio; and people have been asking me about my "secret ways" of gaining such a high cache hit ratio. Over time I touched various pieces of Cloudflare's caching systems; in late 2016 Continue reading

Building Connectivity Across 27,000 Square Miles

In November 2017, the Internet Society hosted the inaugural Indigenous Connectivity Summit in Santa Fe, New Mexico. The event brought together community network operators, Internet service providers, community members, researchers, policy makers, and Indigenous leadership to work together to bridge the connectivity gap in indigenous communities in North America. One of the participants shared her story.

The Navajo Nation spans over 27,000 square miles across three states, making it the largest indigenous nation in the United States, in both geographic area and population. With such a sizable landmass, network building can face significant challenges.

“Infrastructure and coverage are tricky because of the way that the Navajo Nation is surrounded by highways and railways but none really cross through,” says Sylvia Jordan, Principal IT for the Navajo Nation Division of Community Development. “We are trying to bridge middle mile to last/first mile,” says Jordan, “while maintaining affordability for communities requesting access.”

The unique geographic features of the area can dictate connection quality in many areas on the Navajo Nation. Jordan explains that the ridge around Black Mesa, which is more than 8,000 feet high, is large enough that service can trickle down to some rural communities in the southern part of the Continue reading

How to query your Linux system kernel

How much can your Linux system tell you about the kernel it's running and what commands are available to help you ask? Let's run through some of them.uname The simplest and most straight-forward command for providing information on your kernel is the uname -r command. It provides a succinct answer to your question but in a format that also includes a number of fields each which provides a particular piece of information.$ uname -r 4.15.0-30-generic ^ ^ ^ ^ ^ | | | | | | | | | | | | | | +-- the distribution-specific string | | | +------- the latest bug fix | | +---------- the minor revision | +------------ the major revision +--------------- the kernel version Add an "s" and your output will include the kernel's name:To read this article in full, please click here

iNNOVO Cloud
iNNOVO Cloud truly blew us away with one of the most energy efficient data centers in the world. They decided to run everything as an L3/IP fabric and not have large layer 2 domains (music to our ears). Partnering with OpenStack and Kubernetes, iNNOVO built an environment that brings efficiency and scale to their cloud and blockchain services. In fact, they reduced the time to configure switches by 83%. How’s that for increased efficiency? The best part is that their data center is all about sustainability and they’ve gone above and beyond your average infrastructure. Here’s a hint: think shipping Continue reading
