Secure Software Distribution in an Adversarial WorldDiogo Mónica
Secure software distribution is a hard problem. The thousands of different software update systems in use today, most of which are vulnerable to a myriad of attacks that leave the end users potentially vulnerable to compromise, are a testament to this fact.
With the explosion in popularity of package managers and distributors such as RubyGems, PyPI and npm, more and more of our applications are dependent on small, reusable, modules, developed by thousands of different developers, and distributed by infrastructures outside of our control. Given that distributed systems are only as secure as their weakest link, it only takes compromising one of these modules to be able to compromise the entire infrastructure.
It is time for software developers and publishers to start operating under an attack model that considers the distribution infrastructure itself as being actively malicious, and to start following best practices concerning role responsibility separation, offline storage of signing keys, and routine rotation of signing keys.

The landscape of open source malware analysis tools improves every day. A malware analysis lab can be thought of as a set of entry points into a tool chain. The main entry points are a file, a URL, a network traffic capture, and a memory image. This talk is an examination of the major open source tools that satisfy the analysis requirements for each of these entry points. Each tool’s output can potentially feed into another tool for further analysis. The linking of one tool to the next in a tool chain allows one to build a comprehensive automated malware analysis lab using open source software.
For file analysis, the three major versions of Cuckoo Sandbox will be examined. To analyze a potentially malicious URL, the low-interaction honeyclient, Thug, will be covered. Next, if one has a network capture (PCAP) to analyze, the Bro Network Security Monitor is a great option, and will be covered. Finally, if the analysis target is a memory image, the Volatility Framework will be examined. Each of the inputs and outputs of the tools will be reviewed to expose ways that they can be chained together for the purpose of automation.

Abstract
Pretty Good Privacy (PGP) is a package for securing emails, files communications. It is an open-source
package, which is available online for users. PGP provides some of the most important security services like
Authentication, Confidentiality, and Integrity. PGP Also applies compression techniques for compressing
messages and reducing their size. Also it uses Radix-64 encoding/decoding scheme for email compatibility.
The classic PGP has been formed by independent components and uses a hierarchal structure in which each
component is responsible for providing one of the services or features in PGP. This hierarchal structure forces
all the components, even the independent ones to be executed in a linear way. Because of this structure, each
component waits idle for long a time. As a result, the classic PGP has low performance and high execution time.
By studying this structure, we find out that we can redesign the architecture by using Multi-Agent systems to
eliminate bottlenecks. With this new design, we can achieve higher performance and faster execution time than
the classic PGP. In the proposed scheme, each Agent handles one of the PGP's components and in the
implementation semaphores will be used to handle each agent. By using this technique, we will have
concurrency between the agents and as a result the idle time will decrease and the proposed scheme will get
higher performance and lower execution time than the classic PGP. The experimental results show that our
scheme runs 30% faster than the classic PGP with different configurations of computer hardware.

Software Security Assurance for DevOps - Hewlett Packard Enterprise + Black DuckBlack Duck by Synopsys
Presented August 11, 2016 by Michael Right, Senior Product Manager, HPE Security Fortify; Mike Pittenger, VP of Security Strategy, Black Duck.
Open source software is an integral part of today’s technology ecosystem, powering everything from enterprise and mobile applications to cloud computing, containers and the Internet of Things.
While open source offers attractive economic and productivity benefits for application development, it also presents organizations with significant security challenges. Every year, thousands of new open source security vulnerabilities – such as Heartbleed, Venom and Shellshock – are reported. Unfortunately, many organizations lack visibility into and control of their open source. Addressing this challenge is vital for ensuring security in applications and containers.
Whether you’re building software for customers or for internal use, the majority of the code is likely open source and securing it is no easy task. In this session, you’ll learn about:
• The evolving DevOps and software security assurance lifecycle in the age of open source
• The software security considerations CISOs, security, and development teams must address when using open source
• An automated approach to identifying vulnerabilities and managing software security assurance for custom and open source code.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.
How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.
