Arista BGP EVPN – Overview and Concepts
Introduction Traditionally, Data Centers used lots of Layer 2 links that spanned entire racks, rows, cages, floors, for as far as the eye could see. These large L2 domains were not ideal for a data center, due to the slow convergence, unnecessary broadcasts, and difficulty in administering. To optimize the data center network, we needed […]

The Lavelle Networks SD-WAN software appliance sits within an NFV container in a Microsoft Windows environment for greater control and enhanced network management.
Reaction: Centralization Wins
Warning: in this post, I am going to cross a little into philosophy, governance, and other odd subjects. Here there be dragons. Let me begin by setting the stage:
And the very helpful diagram which accompanies the quote—
The point Todd Hoff, the author makes, is that five years ago he believed the decentralized model would win, in terms of the way the Internet is structured. However, today he doesn’t believe this; centralization is winning. Two points worth considering before jumping into a more general discussion.
First, the decentralized model is almost always the most efficient in almost every respect. It is the model with the lowest signal-to-noise ratio, and the model with the highest gain. The simplest way to explain this is to note the primary costs in a network is the cost of connectivity, and the primary gain is the amount of support connections provide. The distributed model offers the best balance of these two.
Second, what we are generally talking about here Continue reading

Not Like in Hollywood
When we think of hacking, we often picture a grim fellow opening a laptop, typing really fast and bam! he’s infiltrated the Pentagon. Watching those films when you know one or two things about system and network security is a hilarious experience! If you have been following the Certified Ethical Hacker series, you would know better by now. Hacking is not for the faint-hearted, not just because of the technical difficulty (indeed there are several needed skills to be developed), but because of the resilience needed. I’m talking about the fact that a successful hack comes after many failed attempts in most scenarios.
Because hacking into systems as an outsider is so difficult there’s a key toolkit that every hacker needs to master as much as they master sniffing, session hijacking, application hacking, or any other technical specialty- I’m talking about Social Engineering.
It’s a Dark World
A highly empathetic person might have a hard time with the concept of Social Engineering. It’s pretty Continue reading

Watch the Experts Session on Encryption from Canberra
Internet Australia and the Internet Society are pleased to invite you to watch the recording of an Experts Session on Encryption on 20 August 2018 at Parliament House, Canberra, Australia.
Encryption technologies enable Internet users to protect the integrity and the confidentiality of their data and communications. From limiting the impact of data breaches, to securing financial transactions, to keeping messages private, encryption is an essential tool for digital security. As a technical foundation for trust on the Internet, encryption promotes commerce, privacy, and user trust, and helps protect data and communications from bad actors.
During the session, international and local experts from across the field discussed the technical aspects of encryption and digital security. They explained how encryption is used to secure communications and data, and explored its role in the Australian digital economy. Experts also discussed the risks associated with attempting to provide exceptional access to encrypted systems.

The Week in Internet News: U.S. DOJ Pressures Facebook to Break Messenger Encryption
Encryption wars, part 2,403: The U.S. Department of Justice is pressuring Facebook to break the encryption in its Messenger app so that investigators can access communications by suspected Ms-13 gang members. The DOJ has asked a judge to force Facebook to allow the agency to tap into Messenger, with the outcome potentially affecting other tech companies, Fortune reports.
Hacking the Apple: An infamous North Korean hacking group has created their first macOS malware as a way to compromise a cryptocurrency exchange, Bleeping Computer reports. The hackers who created the so-called AppleJeus malware are going to great lengths to make it work – even creating a fake company and software product to deliver it.
AI loves TV: As researchers explore ways to give Artificial Intelligence systems curiosity, AIs will sometimes choose to watch TV all day, QZ.com says. AIs playing video games will sometimes die on purchase to see the game-over screen or fixate on a fake TV and remote and flip through channels to find something new.

Does Establishing More IXPs Keep Data Local? Brazil and Mexico Might Offer Answers
Much like air travel, the internet has certain hubs that play important relay functions in the delivery of information. Just as Heathrow Airport serves as a hub for passengers traveling to or from Europe, AMS-IX (Amsterdam Internet Exchange) is a key hub for information getting in or out of Europe. Instead of airline companies gathering in one place to drop off or pick up passengers, it’s internet service providers coming together to swap data – lots and lots of data.
Where the world’s largest internet exchange points (IXPs) reside are mostly where you would expect to find them: advanced economies with sophisticated internet infrastructure. As internet access reached new populations around the world, however, growth in IXPs lagged and traffic tended to make some roundabout, and seemingly irrational, trips to the more established IXPs.
For example, users connected to a server just a few miles away may be surprised to discover that data will cross an entire ocean, turn 180 degrees, and cross that ocean again to arrive at its destination. This occurrence, known as the “boomeranging” or “hair-pinning” (or “trombone effect” due to the path’s shape), is especially true for emerging markets, where local ISPs are less interconnected and Continue reading
Adaptive Micro-segmentation – Built-in Application Security from the Network to the Workload
A zero trust or least-privileged, security model has long been held as the best way to secure applications and data. At its core, a zero trust security model is based on having a whitelist of known good behaviors for an environment and enforcing this whitelist. This model is preferable to one that depends on identifying attacks in progress because attack methods are always changing, giving attackers the upper hand and leaving defenders a step behind.
The problem for IT and InfoSec teams has always been effectively operationalizing a zero trust model. As applications become increasingly distributed across hybrid environments and new application frameworks allow for constant change, a lack of comprehensive application visibility and consistent security control points is exacerbated for IT and InfoSec, making achieving a zero trust model even harder.
A modern application is not a piece of software running on a single machine — it’s a distributed system. Different pieces of software running on different workloads, networked together. And we have thousands of them, all commingled on a common infrastructure or, more lately, spanning multiple data centers and clouds. Our internal networks have evolved to be relatively flat — a decision designed to facilitate organic growth. But Continue reading
