SSHCure: SSH Intrusion Detection Using NetFlow and IPFIX

Luuk Hendriks — Jun 05, 2014 11:30 AM

SSHCure: SSH Intrusion Detection Using NetFlow and IPFIX 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.

Changes to the Distribution Model for RIPE Atlas Probes

Fatemah Mafi — Jun 03, 2014 01:55 PM

Changes to the Distribution Model for RIPE Atlas Probes As the RIPE Atlas network continues to grow, we have taken another look at our distribution model and made some adjustments to ensure wider topological and geographical probe coverage. Community feedback at RIPE 68, notably regarding RIPE Atlas probe coverage, encouraged the RIPE NCC to audit probe distribution in a stricter manner.

ReFlow: Reports on Internet Flows

Martijn Hoogesteger — Jun 03, 2014 10:15 AM

ReFlow: Reports on Internet Flows The fact that HTTP is the most used application protocol in the Internet is well known. However, statements like this are seldom supported with clear evidence. At the Design and Analysis of Communications Systems (DACS) group, of the University of Twente, we have created ReFlow: a public website containing statistics about general Internet traffic. The main goal of ReFlow is to maintain historical traffic data, allowing for comparisons and analysis of trends on Internet traffic. This way, basic facts on the Internet can be supported with evidence.

Better Crypto - Applied Cryptography Hardening

Aaron Kaplan — May 22, 2014 11:35 AM

Better Crypto - Applied Cryptography Hardening 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.

Survey on Mitigation and Response of Network Attacks

Jessica Steinberger — May 21, 2014 11:40 AM

Survey on Mitigation and Response of Network Attacks 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.

Suggestions for Improving Abuse Contact Management

Denis Walker — May 05, 2014 04:25 PM

The aim of the policy Abuse Contact Management in the RIPE Database (RIPE document ripe-563), was to make available an abuse contact for all resources maintained by the RIPE NCC. The RIPE NCC proposed an implementation plan that was accepted. During the deployment there has been some feedback on the practicalities of the implementation. At RIPE 67 the RIPE NCC agreed to think about this feedback and present some further options.

RIPE Atlas: Latest Results API and Parsing Library

Suzanne Taylor Muzzin — Apr 29, 2014 01:30 PM

RIPE Atlas: Latest Results API and Parsing Library You can now get the latest results from any of your user-defined measurements with a new API created specifically for this purpose. In addition, we've developed a parsing library that can be used in combination with the new API to make it an even more useful tool.

Sending and Receiving Emails over IPv6

Mirjam Kühne — Apr 10, 2014 11:15 AM

Sending and Receiving Emails over IPv6 The change to IPv6 creates new challenges to keep spam out of email. Because of the sheer size of the IPv6 space, it seems more efficient to build a domain-blocking and reputation system rather than an IP-blocking system. But how do we ensure emails over IPv6 have an authenticated domain?
