Deep Dive: Scoring ISPs and Hosts on Privacy and Security
In April 2019 the Internet Society’s Online Trust Alliance (OTA) released its 10th Annual Online Trust Audit & Honor Roll. The Audit looks at the security and privacy practices of over 1,000 of the top sites on the Internet from retailers to governments. In this post we will take a deeper dive into the ISP/Hosts sector of the Audit. This sector is comprised of the top ISPs and other hosting organizations in the U.S. It includes everything from organizations that provide network access to organizations that host email services.
In the Audit, privacy statements are scored across 30 variables. ISP/Hosts were a decidedly mixed bag compared to other sectors, which tended to do either relatively well or poorly across the board in their statements. (Though to clear, the vast majority of organizations in the Audit had poor privacy statements, it was the most common reason for failure across privacy and security scoring.)
ISP/Hosts fell somewhat short in the presentation of their statements. OTA advocates several best practices that deal with how the privacy statement is displayed to make it as easy as possible for users to understand.
The simplest practice OTA advocates is a link to the privacy Continue reading

It’s a fact: choosing your own hardware means lower TCO
An essential part of open networking is the ability to choose your own hardware. This allows for customization of your network to suit business needs, and it can also dramatically reduce your Total Cost of Ownership (TCO). On average, open networking with Cumulus helps customers reduce their capital expenditures (CapEx) by about 45% and operational expenditures (OpEx) in the range of approximately 50% to 75%.
Choosing the right hardware is a big part of these savings. If you compare bare-metal networking equipment with a similar product from a proprietary networking vendor, you’ll quickly find that bare-metal hardware is much less expensive. One reason for this is competition between hardware vendors in the open networking space.
Open networking is a multi-vendor ecosystem. More than 100 switches are certified to work with Cumulus Linux; they’re manufactured by vendors such as Dell, HPE, Mellanox, Supermicro, and others. Unlike with proprietary switches, there’s no vendor lock-in creating a monopoly situation. In the open networking space, vendors compete for sales, and this keeps costs down.
Another factor in lowering costs is the degree of customization available when you have many products to choose from. Choosing your own hardware means buying what you need—and only Continue reading

Public Cloud Cannot Change the Laws of Physics
Listening to public cloud evangelists and marketing departments of vendors selling over-the-cloud networking solutions or multi-cloud orchestration systems, you could start to believe that migrating your workload to a public cloud would solve all your problems… and if you’re gullible enough to listen to them, you’ll get the results you deserve.
Unfortunately, nothing can change the fundamental laws of physics, networking, or application architectures:

Hello my friend,
This year, besides Cisco championship started for me with an opportunity to speak at UKNOF event in London. UKNOF stands for United Kingdom’s Network Operators’ Forum, and per their webpage acts as an open forum for operational, technical and engineering information exchange related to networking technologies and practices. And here is my experience.
How do I get there?
Some time ago I was presenting at NetLdn event in a nice pub in London, and apparently there were some people from the UKNOF board (hey, Chris Russel).
I have an interesting discussion with NetLdn organizers some time ago, you can watch it on our YouTube channel.
They advised me to submit my talk to UKNOF, and if the committee voted for it, I’d have an opportunity to speak in front of quite a big audience at UKNOF 45 in London. I was positively surprised and took that opportunity to apply for a talk. After a month of waiting I finally got an invitation to talk at the 45th UKNOF meeting, which took place in London.
Despite I have an almost ready slide deck, I need to rework it a bit to comply with the event’s Continue reading

I recently purchased a Meraki MV 72 and wanted to share some of the logic behind why I did this. Having 4 other camera ecosystems in “production” at my home, this decision to add number 5 may defy logic for many. My thoughts around this particular investment were more about my personal learning than about function.
To provide a little background, I have a combination of various consumer and prosumer type cameras that vary in form and functionality. Every single brand (and ecosystem), while covering some functions very well, seem to leave a little to be desired. Hence the reason to buy a Meraki MV.
No–I do not expect the Meraki solution to be a perfect solution. Actually, since it is built around business use cases, it might not be as good at somethings that I find very useful. However, there is an API that I wanted to experiment with and solidify my knowledge of how I might build and extend my own ecosystem.
The deeper function of the Meraki MV API is included with MV Sense which is an add-on. Fortunately, every MV Sense organization with capable cameras comes with 10 free licenses. This requires the new generation of Continue reading

Broadband delays: KentuckyWired, an ambitious plan to bring broadband services to underserved, rural parts of the state, is about two years behind schedule, the Courier Journal reports. As a result, the promise of new high-tech jobs has not materialized. About 405,000 residents of Kentucky have no access to wired broadband.
Cities take the lead: Meanwhile, a handful of cities in Oregon are considering municipal broadband projects, KPTV reports. Hillsboro is about to join the ranks of cities offering city-funded connectivity.
Tweets against encryption: U.S. President Donald Trump has tweeted a demand for Apple to defeat encryption on iPhones owned by criminal suspects, CNet says. Administration officials have criticized Apple for not unlocking a phone used by a dead mass shooter.
Election hacking: A security researcher has found that an election server in the U.S. state of Georgia may have been hacked in 2014, before a tight 2018 race for governor, Politico reports. If hackers did manage to breach the server, they would have “almost total control” of it, including the abilities to modify files, delete data, and install malware,” election security expert Logan Lamb said.

GPON vs. Traditional Ethernet Architecture
GPON (Gigabit Passive Optical Network) is used to reduce the number of active switching nodes in the network design. Network Design Best practice in Campus networks and many Datacenter networks (Not Massively Scale Datacenters), is to use Three-Tier; Access, Distribution and Core network design. Although the design decision depends on the scalability requirements in the Campus and DC, two layer; Access and Collapsed Distribution/Core design can be used. Below figure depicts common three tier Access, Distribution and Core design.
This post was first published on “Service Provider Networks Design and Architecture by Orhan Ergun” book.
Figure – GPON vs. Traditional Ethernet Architecture, Source: cisco.com
In Three-tier Traditional campus networks, there are active Ethernet devices used in each tier. Active means, nodes require electricity. Active Ethernet switches forward traffic based on forwarding rules. If it’s a Layer 2 network, traffic is forwarded based on Layer 2 information, if it is a Layer 3 design, traffic is forwarded based on routing protocol information.
GPON in the campus network replaces traditional three-tier design with two-tier optical network, by removing the Active access and distribution layer Ethernet switches with the ONT, Splitter and OLT devices. Although ONT Continue reading
