Freelab: a Free Experimentation Platform
FreeLab: A Free Experimentation Platform Matteo Varvello|; Diego Perino? |AT&T Labs – Research, ?Telefónica Research ABSTRACT In this work, we set out to build a free experimentation As researchers, we are aware of how hard it is to obtain access platform which can also be reliable and up-to-date. In classic to vantage points in the Internet. Experimentation platforms experimentation platforms applications run directly at vantage are useful tools, but they are also: 1) paid, either via a mem- points; we revert this rationale by proposing to use vantage bership fee or by resource sharing, 2) unreliable, nodes come points as traffic relays while running the application at theex- and go, 3) outdated, often still run on their original hardware perimenter’s machine(s). By leveraging free Internet relays as and OS. While one could build yet-another platform with vantage points, we can make such experimentation platform up-to-date and reliable hardware and software, it is hard to free. The drawback of this approach is the introduction of imagine one which is free. This is the goal of this paper: we extra errors (path inflation, header manipulation, bandwidth set out to build FreeLab, a free experimentation platform shrinkage) which need to be carefully corrected. which also aims to be reliable and up-to-date. The key idea This paper presents FreeLab, a free experimentation plat- behind FreeLab is that experiments run directly at its user form built atop of thousand of free HTTP(S) and SOCKS(5) machines, while traffic is relayed by free vantage points inthe Internet proxies [38]—to enable experiments based on TCP, Internet (web and SOCKS proxies, and DNS resolvers). -
Major Qualifying Project
Network Anomaly Detection Utilizing Robust Principal Component Analysis Major Qualifying Project Advisors: PROFESSORS LANE HARRISON,RANDY PAFFENROTH Written By: AURA VELARDE RAMIREZ ERIK SOLA PLEITEZ A Major Qualifying Project WORCESTER POLYTECHNIC INSTITUTE Submitted to the Faculty of the Worcester Polytechnic Institute in partial fulfillment of the requirements for the Degree of Bachelor of Science in Computer Science. AUGUST 24, 2017 - MARCH 2, 2018 ABSTRACT n this Major Qualifying Project, we focus on the development of a visualization-enabled anomaly detection system. We examine the 2011 VAST dataset challenge to efficiently Igenerate meaningful features and apply Robust Principal Component Analysis (RPCA) to detect any data points estimated to be anomalous. This is done through an infrastructure that promotes the closing of the loop from feature generation to anomaly detection through RPCA. We enable our user to choose subsets of the data through a web application and learn through visualization systems where problems are within their chosen local data slice. In this report, we explore both feature engineering techniques along with optimizing RPCA which ultimately lead to a generalized approach for detecting anomalies within a defined network architecture. i TABLE OF CONTENTS Page List of Tables v List of Figures vii 1 Introduction 1 1.1 Introduction .......................................... 1 2 VAST Dataset Challenge3 2.1 2011 VAST Dataset...................................... 3 2.2 Attacks in the VAST Dataset ................................ 6 2.3 Avoiding Data Snooping ................................... 7 2.4 Previous Work......................................... 8 3 Anomalies in Cyber Security9 3.1 Anomaly detection methods................................. 9 4 Feature Engineering 12 4.1 Feature Engineering Process ................................ 12 4.2 Feature Selection For a Dataset.............................. -

It is a midweight OS designed to combine an elegant and efficient desktop with simple configuration, high stability, solid performance and medium-sized footprint. Relying on the excellent upstream work by Linux and the open-source community, we deploy Xfce 4.12 as Desktop Environment on top of a Debian Stable base, drawing from the core antiX system. Ongoing backports and outside additions to our Repos serve to keep components current with developments.
