We’d like to enable gzip compression on all of RIPE Atlas' measurement API calls — but thanks to the BREACH vulnerability, doing so could mean that some enterprising individual with an obscene amount of time on their hands might be able read the contents of the responses. This means measurement results as well as metadata for measurements — including the small number of measurements not marked as “public”. We believe the drawbacks are negligible, but we’re looking for community support.
In this post (originally published on the APNIC blog), Cengiz Alaettinoglou gives a brief overview and comparison of the IRR and SIDR security models and shares his thoughts about the chances for these models to succeed.
RPKI.me is a website collecting statistics and information about objects in the RPKI repositories. The web page shows some of the most problematic ROAs present and suggests possible fixes.
ENISA, the European Union Agency for Network & Information Security, is an independent body of expertise, set up by the European Union, to secure Europe’s information society. It was founded in 2004 to facilitate the exchange of information between EU institutions, the public and the private sector. The goal is to work together with operational communities to identify pragmatic solutions to current security issues. In this first article, we have asked ENISA to introduce themselves and highlight some of their activities that could be of interest to the RIPE community.
Microsoft ended support for Windows XP as of April 2014. We're about to change RIPE Atlas and RIPEstat to stop support for Internet Explorer 8 running on these systems.
This is a call for participation in a survey on Internet Routing Security. The survey runs until 9 January 2015 and will only take a few minutes.
Much has been said over the pasts year or so about various forms of cyber spying. The United States has accused the Chinese of cyber espionage and stealing industrial secrets. A former contractor to the United States' NSA, Edward Snowden, has accused various US intelligence agencies of systematic examination of activity on various popular social network services, through a program called “PRISM”. These days cloud services may be all the vogue, but there is also an emerging understanding that once your data heads off into one of these clouds, then it’s no longer necessarily entirely your data; it may have become somebody else's data too.
Yes, that's a cryptic topic, even for an article that addresses matters of the use of cryptographic algorithms, so congratulations for getting even this far! This is a report of an experiment conducted in September and October 2014 by the authors to measure the extent to which deployed DNSSEC-validating resolvers fully support the use of the Elliptic Curve Digital Signature Algorithm (ECDSA) with curve P-256.
It has been a very busy period in the domain of computer security. With "shellshock", "heartbleed" and NTP monlink adding to the background of open DNS resolvers, port 445 viral nasties, SYN attacks and other forms of vulnerability exploits, it's getting very hard to see the forest for the trees. We are spending large amounts of resources in reacting to various vulnerabilities and attempting to mitigate individual network attacks, but are we making overall progress? What activities would constitute "progress" anyway?
Last week we improved the security of our routing infrastructure by implementing RPKI (Resource Public Key Infrastructure), a technology that can be used to secure the Internet routing infrastructure. RPKI was the topic of my Master's thesis and in this article I am trying to convince you to use this important technology for a more secure Internet.
SSHCure is an Intrusion Detection System for SSH, developed at the University of Twente. It allows analysing large amounts of flow data and is the first IDS capable of identifying actual compromises. Being deployed in various networks, ranging from small Web-hosting companies to nation-wide backbone networks, SSHCure has proven to be a stable system in high-speed networks.
This project aims at creating a simple, copy & paste-able HOWTO for secure crypto settings of the most common services (webservers, mail, ssh, etc.). It was presented at the recent RIPE 68 Meeting in Warsaw. For those of you who couldn't attend the meeting, here is summary of the talk.
Network-based attacks pose a strong threat to the Internet landscape. In my PhD I am investigating different approaches on attack mitigation and response. Yet, a clear understanding of how mitigation and response is performed in commercial networks is missing. Hence, this survey aims at gaining insight in real-world processes, structures and capabilities of IT companies and the computer networks they run.
The Dutch Institute for Applied Scientific Research (TNO) and a number of Dutch security companies have recently published a report on IPv6 security test methodologies.
In this article Geoff Huston describes attacks that involve the Network Time Protocol (NTP) and what can be done to defend against them.
We wanted to find out what network security experts think about network anomalies. We created a short web survey in order to map opinions of network professionals. In this article we describe the results.
Before we decide to implement a stricter operational practices, we needed to find out how many routes with invalid origins are actually being used and how much traffic is exchanged using those routes. Please find the results below.
After the recent amplification attacks involving NTP servers, John Kristoff, a researcher with Team Cymru, kindly agreed to publish an analysis of the history and timeline leading up to the attacks. Please find his contribution below.
Network anomalies are not understood the same way among the network experts. However, establishing a unified view is important for the development of anomaly detection tools. The survey described below will help to develop such a unified view.
