Information security in the telecom industry
DDoS attacks using botnets are a headache for network operators. We discuss the most popular attack vectors: the "classic" flood, smurf attack and ping flood. We will also tell you how to prevent them.
Last year, information security experts discovered malware that attacked 400 routers. The targets were devices with the BroadCom UPnP function activated. Read the article about infection mechanisms: used ports and virus tools.
Cellular operators in the United States are implementing subscriber authentication technology - the SHAKEN / STIR standard. We describe the principles of the protocol - the article has a flowchart and code examples American telecom.
DDoS attacks are a threat to IoT and 5G. The material talks about two methods for protecting the networks of Internet providers and mobile operators: comprehensive traffic cleaning centers and a budget option with built-in security systems.
Network technologies
Temporospatial SDN is a system for deploying software-defined networks in orbit. It will manage the satellite infrastructure and balloons that distribute the Internet to remote corners of the planet. How the system works and what difficulties developers still have to solve - read in the material.
An international group of physicists managed to develop a quantum repeater capable (unlike analogs) of operating at room temperature. It could be the key to deploying global quantum networks. We tell what the innovation is and discuss other technologies that bring the creation of the quantum Internet closer - artificial diamonds for transmitting qubits and error correction algorithms.
Australian engineers have proposed to encode light in an optical fiber using the spin of a photon. In theory, the technology will increase network bandwidth by a hundred times. This could happen within the next two years. In the article - about the components of the system, the materials used (for example, antimony telluride) and the principles of operation.
For the first time, German researchers have achieved a data transfer rate of 500 Gb / s in the "field" conditions. To do this, they developed an algorithm for the probabilistic formation of a signal constellation (Probabilistic Constellation Shaping, or PCS). The material will tell about the principles of operation of probabilistic modulation and its analogue - geometric modulation.

Standards
We analyze the most popular questions that telecom operators have when switching to IPv6: about potential problems with hardware and client equipment.
This year, Compute Express Link is released - a standard that will provide high-speed data transfer between components of heterogeneous systems (CPU, FPGA and GPU). The article contains details of the specification, technical parameters and shortcomings of the standard, which are noted by IT industry experts. Let's talk about analogues - the CCIX and GenZ standards.
USB4-based devices will not appear until 2021. But some characteristics of the standard are already known: a bandwidth of 40 Gb / s, the ability to simultaneously charge and display an image. We discuss what could go wrong.
We compare Russian and foreign experience in implementing IPv6 in IoT networks and industry. We discuss approaches to migration and the experience of using this protocol by various organizations.
Legislation in IT
Fresh article that continues about Net Neutrality. We will talk about a new bill - the act "On saving the Internet", which will have to "roll back" the rules of net neutrality to the state of 2015. Here are the opinions of representatives of the authorities and the industry, we are talking about the prospects of the initiative.
The Japanese authorities are proposing to pass a bill that will prohibit users from downloading all files protected by copyright from the network. Read the article about the reaction of Japanese publishers, content makers, scientists and lawyers.
This is a practical guide about deploying hotspots in public places. We tell you what to pay attention to so as not to break the law. You will also find here recommendations for choosing equipment.
