Mutually Agreed Norms for Routing Security (MANRS): an analysis of uptake in the EU - March 2022
No full textThe actions proposed by the Mutually Agreed Norms for Routing Security (MANRS) initiative aim to strengthen the security of the global Internet routing system, thus improving the interoperability, scalability, stability, and security of the Internet. This report provides an overview of the current level of adoption of routing standards, including MANRS actions, in Q1 2022 across EU Member States, as well as globally. The analysis of the level of uptake of routing standards has been carried out using publicly available data.JRC.E.3 - Cyber and Digital Citizens' Securit
Domain Name System Security Extensions (DNSSEC) standards: an analysis of uptake in the EU - March 2022
No full textA high level of adoption of Domain Name System Security Extensions (DNSSEC) is essential to protect the integrity of the Domain Name System (DNS) Internet infrastructure to ensure the interoperability and security of the global cyberspace. This report provides an analysis of the level of adoption of DNSSEC in Q1 2022 across EU Member States and globally, using data publicly available as well as from measurements conducted by the European Commission’s Joint Research Centre. The report also presents an analysis of the following additional standards designed to protect the confidentiality of DNS communications, namely DNS over TLS (DoT), DNS over HTTPS (DoH) and DNS over QUIC (DoQ).JRC.E.3 - Cyber and Digital Citizens' Securit
Der griechische Gelehrte Georgios Zachariadis und sein Beitrag zum slawischen Schrifttum im 19. Jahrhundert
No full textAmong the Greek scholars who lived during the 19th century in the north-eastern Balkans, and also in Central Europe, and by their work contributed to the spiritual development of the Balkan Slavs, pride of place must be given to Georgios Zachariadis. Unfortunately, however, no detailed monograph on Zachariadis exists. On this account the problems that arise concerning the life and activities of this Greek scholar are still many and varied. In his study the author tries to fill one part of this lacuna. At the beginning of the work the following are examined, on the basis of new historical evidence: the date and place of Georgios Zachariadis’ birth, his studies and tenure as teacher in the Greek school at Zemun, the Serbian school at Šabac, and the Greek school in Vienna. The author continues his study by analyzing the various works of Zachariadis, which are written on Old Church^Slavonic, and the translations this Greek scholar made from Greek into Old Church Slavonic. Finally, the extent of Georgios Zachariadis’ contribution to Slavonic letters is made clear

Internet Standards: Mutually Agreed Norms for Routing Security (MANRS) - an analysis of uptake in the EU
No full textThe actions proposed by the Mutually Agreed Norms for Routing Security (MANRS) initiative aim to strengthen the security of the global Internet routing system, thus improving the interoperability, scalability, stability, and security of the Internet. This report provides an overview of the current level of adoption of routing standards, including MANRS actions, in Q1 2024 across EU Member States, as well as globally. The analysis of the level of uptake of routing standards has been carried out using publicly available data. In our results we observed a compliance rate of over 97% for compulsory actions for network operators.JRC.T.2 - Cybersecurity and Digital Technologie
Neither Denied nor Exposed: Fixing WebRTC Privacy Leaks
No full textTo establish peer-to-peer connections and achieve real-time web-based communication, the Web Real-Time Communication (WebRTC) framework requires address information of the communicating peers. This means that users behind, say, Network Address Translation (NAT) or firewalls normally rely on the Interactive Connectivity Establishment (ICE) framework for the sake of negotiating information about the connection and media transferring. This typically involves Session Traversal Utilities for NAT (STUN)/Traversal using Relays around NAT (TURN) servers, which assist the peers with discovering each other’s private and public IP:port, and relay traffic if direct connection fails. Nevertheless, these IP:port pieces of data can be easily captured by anyone who controls the corresponding STUN/TURN server, and even more become readily available to the JavaScript application running on the webpage. While this is acceptable for a user that deliberately initiates a WebRTC connection, it becomes a worrisome privacy issue for those being unaware that such a connection is attempted. Furthermore, the application acquires more information about the local network architecture compared to what is exposed in usual HTTP interactions, where only the public IP is visible. Even though this problem is well-known in the related literature, no practical solution has been proposed so far. To this end, and for the sake of detecting and preventing in real time the execution of STUN/TURN clandestine, privacy-invading requests, we introduce two different kinds of solutions: (a) a browser extension, and (b) an HTTP gateway, implemented in C++ as well as in Golang. Both solutions detect any WebRTC API call before it happens and inform accordingly the end-user about the webpage’s intentions. We meticulously evaluate the proposed schemes in terms of performance and demonstrate that, even in the worst case, the latency introduced is tolerable
Neither Good nor Bad: A Large-Scale Empirical Analysis of HTTP Security Response Headers
No full textHTTP response headers can be of great aid to web applications to-wards augmenting their overall security level. That is, if set at the server side, these headers define whether certain security countermeasures are in place for protecting end-users. By utilising the curated Tranco list, this work conducts a wide-scale internet measurement that provides timely answers to the following questions: (a) How the adoption of these headers is developing over time?, (b) What is the penetration ratio of each key header in the community?, (c) Are there
any differences in the support of these headers between different major browsers and platforms?, (d) Does the version of a browser (outdated vs. new) affects the support rate per key header?, and (e) Is the status of a header (active vs. dep-recated) reflected to its support rate by web servers? Setting aside the use of the more robust Tranco corpus, to our knowledge, with reference to literature,
the contributions regarding the fourth and fifth questions are novel. Our analysis shows that the support of headers is somewhat related to the browser version, the penetration ratio of the top favourable headers fluctuates between approximately 11.8 and 15.5% across all platforms, interestingly outdated browser versions may be better supported in terms of headers, and deprecated headers still enjoy wide
