IDG Contributor Network: Zero-trust: microsegmentation networking

The transformation to the digital age has introduced significant changes to the cloud and data center environments. This has compelled the organizations to innovate more quickly than ever before. This, however, brings with it both – the advantages and disadvantages.The network and security need to keep up with this rapid pace of change. If you cannot match with the speed of the digital age, then ultimately bad actors will become a hazard. Therefore, the organizations must move to a zero-trust environment: default deny, with least privilege access. In today’s evolving digital world this is the primary key to success.To read this article in full, please click here

Cognitive WiFi is Here

cognitive-campus-blog-ju-19

Last August, Arista made its first acquisition, Mojo Networks, to transform the future of WiFi and campus networks. Just as Arista disrupted the datacenter with important architectural and technology-based innovations, I believe this is a similar pioneering step for the campus. Over the past two decades, the industry has deployed a WiFi controller-based architecture. This stagnant “WLC” approach for wireless connectivity has not evolved to address costly operational dilemmas such as:

Automatic Clean-and-Updated Firewall Ruleset

This is a guest blog post by Andrea Dainese, senior network and security architect, and author of UNetLab (now EVE-NG) and  Route Reflector Labs. These days you’ll find him busy automating Cisco ACI deployments.

Following the Ivan’s post about Firewall Ruleset Automation, I decided to take a step forward: can we always have up-to-date and clean firewall policies without stale rules?

The problem

We usually configure and manage firewalls using a process like this:

5G: A deep dive into fast, new wireless

The next step in the evolution of wireless WAN communications - 5G networks - is about to hit the front pages, and for good reason: it will complete the evolution of cellular from wireline augmentation to wireline replacement, and strategically from mobile-first to mobile-only.To read this article in full, please click here(Insider Story)

What is 5G? How is it better than 4G?

5G wireless is an umbrella term to describe a set of standards and technologies for a radically faster wireless internet that ideally is up to 20 times faster with 120 times less latency than 4G, setting the stage for IoT networking advances and support for new high-bandwidth applications.What is 5G? Technology or buzzword? It will be years before the technology reaches its full potential worldwide, but meanwhile some 5G network services are being rolled out today. 5G is as much a marketing buzzword as a technical term, and not all services marketed as 5G are standard.To read this article in full, please click here

The Week in Internet News: U.S. Census Seeks Help with Fake News from Tech Giants

Fake news fears: The U.S. Census Bureau is seeking help from Google, Facebook, and Twitter to fight off fake news during its 2020 population count, Reuters reports. Some groups appear to be targeting the census as a way to redirect congressional representation and federal funding.

Broadband for all: The Vermont House has voted for a bill to add funding for broadband deployment, including community broadband projects, Vermont Public Radio reports. About 17,000 Vermont residents don’t have broadband available, and many others have slow Internet service.

Copyright rules divide: New copyright rules in the European Union may lead to a different Internet experience there, The Verge says. With the EU’s Copyright Directive, there’s now a European Internet that feels different that the U.S. Internet and the authoritarian Internet in some countries, the story says. Among other things, the new rules allow publishers to charge platforms like Google News for displaying snippets of stories.

Encryption rising: The use of encryption by large companies has hit an all-time high, Dark Reading notes. About 45 percent of enterprises have encryption plans in place.

Fake news fighters: Facebook has launched a fake-news fighting effort in India as the country heads toward elections, Time. Continue reading

Switzerland’s Leading Provider of Customized Financial Services for Dental Facilities Ensures the Safe Handling of Patient Records

The core business of Zahnärztekasse AG revolves around financial services for dentists and therefore secure patient records. The 33 employees look after the fee management of over 1,000 dental facilities in Switzerland. Recently, the company introduced a new level of security, because in the face of current threats and threats of cybercrime, sensitive data can fall into the wrong hands. The dental facilities often ask about the level of safety of the IT products and services offered. In addition, it is necessary to comply with the new federal law on data protection, the Swiss counterpart to GDPR. Therefore, IT security is very important. A digital transformation was necessary, because the systems in use were not completely protected against current threat scenarios. Furthermore, Zahnärztekasse was also striving for an ISO certification.

 

Interfaces and platforms already digitized

Digitalization is a major challenge for the conservative dental market. Zahnärztekasse has responded to this trend by digitizing its assets including interfaces, various platforms (www.debident.ch and www.zahngeld.ch) and the iOS app Crediflex, and is now considered to be a market leader and pioneer in the field. As early as 2010, Zahnärztekasse started virtualizing its systems and built on this trend Continue reading

Choose Simple Solutions

In my experience, simplicity is not valued enough in software development. Instead, there is a lot of emphasis placed on flexibility. —Felix

Replace “software” with “network,” and think about it. How often do network engineers select the chassis-based system that promises to “never need to be replaced?” How often do we build networks like they will be “in use” 20+ years from now? Now it does happen from time to time; I have heard of devices with many years of uptime, for instance. I have worked on AT&T Brouters in production—essentially a Cisco AGS+ rebranded and resold by AT&T—that were some ten or fifteen years old even back when I worked on them. These things certainly happen, and sometimes they even happen for good reasons.

But knowing such things happen and planning for such things to happen are two different mindsets. At least some of the complexity in networks comes from just this sort of “must make it permanent: thinking:

Many developers like to write code which handles any problem which might appear at any point in the future. In that regard, they are fortune tellers, trying to find a solution for eventual problems. This can work out very Continue reading
