Digital Footprint: on-line course for children in the Czech Republic

In September this year, the Czech Safer Internet Centre (CZ.NIC), in cooperation with the National Cyber and Information Security Authority, presented an online course called Digital Footprint, intended primarily for children aged 10-13. This interactive game focuses on Internet privacy and associated socio-pathological phenomena such as personal data abuse, sexting, digital privacy or cyberbullying.

Open sesame!

Once upon a time, in a company far, far away, they build a bike shed. The actual bike shed. Surprisingly without any bike-shedding. But then they were wondering how to give access to all the cyclists to the yard bike shed was build on. It was not a highly secured area, but still, it was behind gates so no stray dogs or stray cars could enter. They already had a remote-controlled gate via special key fob. But those were expensive, required some tracking, it took quite some time to order a new one and in general there was quite some overhead managing them.

Mozilla is solving IoT issues using Turris Omnia

IoT

IoT or Internet of Things is a real hype nowadays. Everybody is talking about it and everybody is doing it. Especially companies producing various electronic devices like light bulbs, electric switches, thermometers, scales, CCTV and such. Everything can be smart – even your toilet. All you need to do is to measure something or replace the manual switch with electronic one and connect it to Bluetooth, Zigbee, ZWave or even WiFi and you have a smart device that people will pay a hefty price for. But there are some issues (apart from the obvious one that not all those devices make sense).

Error in DNSSEC implementation on F5 BIG-IP load balancers

During the development of the DNS Knot Resolver, CZ.NIC Labs have managed to reveal a security flaw that makes it possible to bypass DNSSEC security on F5 load balancers and cause denial of service. These products are being used, for example, in some internet banking applications, including those of Czech banks and public authorities. From the perspective of a user attempting to access an internet banking service, a successful attack exploiting this error would manifest in the browser suddenly reporting an “address not found” error and the service becoming unavailable.

We are not afraid to be offline together

The CZ.NIC Association joined the campaign – Family Offline Week with the subtitle “We are not afraid to be offline together“, which will be held this year from May 11 to May 19, 2019. The purpose of the 4th year of the campaign is not only to celebrate the International Family Day, on May 15, but above all to think about the excessive use of digital technology. The uncontrolled use of mobile phones, tablets and computers not only causes health problems but also worsens interpersonal relationships. Children from early age play with tablets and mobiles, often losing social contact with their peers.

A behind-the-scenes look at the production of Turris MOX cases

From the beginning of the development of the Turris MOX router, we have faced a difficult task –how to assemble the modular system so that it does not collapse during handling and, at the same time, make it as user friendly as possible when the user deciders to disassemble and reassemble it. You will be able to find out whether we have accomplished this task or not in the coming weeks when the first MOXes in cases arrive to their users. In the following article, I would like to introduce you to the development and production of the final case of our new product.
