Encryption Is Key to Safety of Journalists

At a time when we notice increasing and alarming threats to media freedom around the world, World Press Freedom Day (WPFD) is more pertinent today than ever before. We therefore can’t afford to celebrate this important day without both considering the damage done to the free press over the past year and intensifying our efforts to protect journalists and the future of journalism around the world.

To ensure that we can continue to celebrate the media’s vital role in democracies in the future, we must tackle the increasing number of Internet shutdowns around the world and find better ways to secure the safety of journalists.

Let’s start with the latter. The surveillance of journalists, in particular, has profound implications for democratic institutions, including freedom of the press. It threatens journalists’ ability to confidently and confidentially work with sources and to unlock information about controversial issues. It therefore hinders their ability to play their roles as watchdogs in democratic or undemocratic, developed or developing societies alike. But reports indicate that more and more journalists are at risk of facing state or societal surveillance.

Encryption offers a vital and relatively simple defense for such intrusions. Building on last year’s Continue reading

Call for Contributions to Northern Public Affairs: Internet Connectivity in Indigenous and Northern Communities

Northern Public Affairs, in collaboration with the Internet Society, is pleased to release a call for contributions to the Fall 2018 special issue of NPA Magazine focusing on emerging developments in community networks among Indigenous peoples in North America.

Internet connectivity for Indigenous Peoples in Canada and the United States has long been difficult to implement due to many environmental and socioeconomic factors such as remoteness of communities, difficulty gaining first mile access, reliable networks, slow speeds, expensive equipment, and high data costs. Community networks are communications infrastructure deployed and operated by local people, offering Indigenous communities a way to access the Internet to meet their own needs. For many, affordable, high-quality Internet access means community sustainability. Community networks encourage policymakers and regulators to examine new ways and means to fill local digital divides, like supporting local content in the appropriate language(s).

In this special edition issue of NPA Magazine the goal is to assemble diverse voices to explore the impact of access in the areas of education, healthcare, digital literacy, cultural/language promotion and preservation, as well as any negative impacts. We will seek existing Indigenous Community Networks and developing ones, highlighting successful and promising initiatives bringing Internet connectivity Continue reading

Custom Page Selection for Cloudflare Apps

Custom Page Selection for Cloudflare Apps

In July 2016, Cloudflare integrated with Eager - an apps platform. During this integration, several decisions were made to ensure an optimal experience installing apps. We wanted to make sure site owners on Cloudflare could customize and install an app with the minimal number of clicks possible. Customizability often adds complexity and clicks for the user. We’ve been tinkering to find the right balance of user control and simplicity since.

When installing an app, a site owner must select where - what URLs on their site - they want what apps installed. Our original plan for selecting the URLs an app would be installed on took a few twists and turns. Our end decision was to utilize our Always Online crawler to pre-populate a tree of the user’s site. Always Online is a feature that crawls Cloudflare sites and serves pages from our cache if the site goes down.

The benefits to this original setup are:
1. Only valid pages appear
An app only allows installations on html pages. For example, since injecting Javascript into a JPEG image isn’t possible, we would prevent the installer from trying it by not showing that path. Preventing the user from that type of Continue reading

Cisco to MikroTik – MPLS

About the Cisco to MikroTik series

One of the hardest things to do quickly in network engineering, is learn a new syntax for a NOS. Especially if you have a tight deadline and need to stand up equipment you’ve never worked with before. The command structure for RouterOS can be cumbersome if you are used to the Cisco CLI.

If you’ve been in networking for a while, you probably started with learning the Cisco CLI. Therefore, it is helpful to compare the commands if you want to implement a network with a MikroTik and Cisco routers.

This is the third post in a series that creates a Rosetta stone between IOS and RouterOS. We plan to tackle  other command comparisons like VLANs, QoS and basic operations to make it easier for network engineers trained in Cisco IOS to successfully implement Mikrotik / RouterOS devices.

While many commands have almost the exact same information, others are as close as possible. Since there isn’t always an exact match, sometimes you may have to run Continue reading

IDG Contributor Network: Get a better angle on your network monitoring with application management

With any new network monitoring and management software, the first step is to assess your existing inventory. Do this by allowing the software to discover all your devices. Your new software may alert you to things you didn’t know you had. Network monitoring and management tooling may be smart enough to propose ways to improve your system: it might suggest new configurations or highlight bottlenecks. Your last step is to let the Simple Network Management Protocol (SNMP) traps flow and inform you about day-to-day network usage.One blessing of the OSI model is that it has enabled innovation at the individual layers. These layers are abstracted from one another, which prevents accidentally injecting dependencies into other layers. The curse of the OSI model is that it has socially separated the people who work at the individual layers from one another—someone working at one layer may never think of someone else working at a different layer. It’s a recurring problem in network monitoring and management, in general.To read this article in full, please click here

Internet Society, LACNIC, and LAC-IX Partner to Strengthen IXPs in Latin America

Wednesday, 2 May 2018, the Internet Society signed a Memorandum of Understanding with the Association of Internet Exchange Points (LAC-IX) and the Latin American Registry for Internet Numbers (LACNIC) to create and strengthen Internet Exchange Points (IXPs) for a stable, secure, and open Internet and to maximise the impact of our activities across Latin America and the Caribbean.

Internet Society’s work on interconnection, traffic exchange, and IXPs not only improves local Internet service in developed regions, but also engages with the local communities that are instrumental in advancing the Internet Society’s mission. The IXP program helps develop Internet technical communities and network operators across the globe.

The Internet Society cooperates with regional organisations that lead IXP work in the field, supporting their work, promoting new IXPs where needed, and helping spread Internet Society work that is valuable to their communities.

LAC-IX and LACNIC have a unique role in promoting new IXPs, supporting existing communities, and, through them, providing the messages that contribute to a stable and scalable Internet.

This Memorandum of Understanding establishes a reference framework for cooperation mechanisms between the Parties. Plans include supporting capacity-building events, disseminating common initiatives and projects, and promoting good routing practices at traffic exchange Continue reading
