Introducing Desktop Grids and integration with Service Grids such as EGEE

Introducing Desktop Grids and integration with Service Grids such as EGEE (90 mins)
Ad Emmen, Peter Kacsuk

Grids? Clouds? Computer infrastructure on-demand! Computers grow older while you watch them Each second you do not use your computer is a second lost forever. You cannot "save" hard disk space for later if you do not use it. A computer at home or in the office, costs money and uses energy.

On the other hand - do not have enough computer power or disk space - when you need it, can be just as bad. Suppose you are a small company and you just did introduce a
new computer based service that does extremely well beyond all expectations and you get thousands of new customers all accessing your system that is too small to handle
it. By the time you ordered and installed new computers, your customers are already gone, disappointed with your service.

But advanced computing techniques, with exotic names as Grid computing and Cloud computing now enable a computer infrastructure on-demand. This can be applied in science and industry.

This tutorial focuses on Desktop Grid computing put in context of computer infrastructure on-demand. The concepts and most important software projects will be described, including BOINC, XtremWeb and EDGeS. Comparisons with commercial Desktop Grid software, such as GridMP, LSF Desktop, will be made.

It will be shown how Desktop Grids works and how a BOINC Grid and an XtremWeb Grid can be set up.

Desktop Grids will be compared to Service Grids, such as EGEE, and an introduction will be given into the EDGeS Grid infrastructure that connects both types of Grids with Bridges. The tutorial will explain what to do if you want to extend an EGEE VO with volunteer or local Desktop Grids or you want to connect your Desktop Grid to EGEE in order to get resources from EGEE.

Target Audience:
Persons considering setting up a Desktop Grid, or using it for applications. Grid experts that are new to Desktop Grids. Representatives of EGEE VO communities that would like to extend their EGEE resources with connected Desktop Grids. Representatives of Desktop Grids who would like to connect their Desktop Grid to EGEE via the EDGeS infrastructure.

Usage Control for Next Generation Grids

Usage Control for Next Generation Grids (1/2) (90 mins)
Alvaro Arenas (STFC RAL, UK); Lorenzo Blasi (HP, Italy); Giovanni Cortese (Interplay, Italy); Bruno Crispo (VUA, Netherlands, and Univ. Trento, Italy); Fabio Martinelli (CNR, Italy); Philippe Massonet

Usage control is an authorisation framework that extends traditional access control by controlling data access as well as usage. This tutorial presents how to model and implement usage control for Grids. The tutorial comprises five parts: an introduction to the usage control model; an OGSA-based architecture for usage control; usage control policies in XACML; an alternative policy language for usage control in Grids; and two case studies showing the application of usage control in Grid systems
The “Usage Control for Next Generation Grids” tutorial consists of the following six talks:

Usage Control for Grids.
The usage control model (UCON) is a new access control paradigm proposed by Park and Sandhu that encompasses and extends different existing models. Its main novelty, in addition to the unification view, is based on continuity of usage monitoring and mutability of attributes. This talk introduces the usage control model and highlights the challenges in controlling resource usage in Grid systems.

An Architecture for Usage Control in Grids.
This talk describes an OGSA-based architecture for implementing usage control for Grids. The architecture has been developed in the EU GridTrust project, extending the current Grid Security Infrastructure (GSI) to deal with usage control.

Usage Control Policies in XACML.
XACML is the standard language for access control in distributed systems. This talk presents how XACML has been extended and used for the specific purpose of expressing and supporting usage control in Grid applications. Particular emphasis will be given to performance and scalability issues. Furthermore, the talk will address the issue of the interaction of scheduling with access control.

Usage Control in Action: Controlling Service Usage in a Grid-Based Content Management System.
This talk presents a case study of the application of usage control based on XACML. The case study is a grid-based content management system that supports a distributed organization in the execution of collaborative projects, aiming at the production of a complex ‘digital’ product. The production process is structured along a workflow such as a software production process or a web / content publishing process.

PolPA: A Usage Control Policy Language for Grids.
Policies languages as XACML cannot express the full potentiality of usage control models such as UCON. This talk shows an alternative policy language, PolPA, that has been designed specifically for expressing usage control policies and has been tailored for dealing with Grids. Since it is based on Process Algebras, PolPA is very expressive and allows to encode all the core models that have been defined by Park and Sandhu. This talk also describes a reference architecture to enforce PolPA in Grid systems.

Usage Control in Action: Controlling Resource Usage in a Grid-Based Supply Chain.
This talk presents a case study of the application of usage control based on PolPA. The case study is a transportation supply chain which exploits Grid services for optimizing both the delivery and cost of each customer order. Each transporter uses a Grid-based computing service to re-optimize the routes of its vehicles’ fleet after the addition of each new transportation task. Transporters submit their routing jobs to a Grid portal supported by their association. Local usage control policies allow computational service providers to protect their resources and other transporters’ data.

Vulnerability Assessment and Secure Coding Practices for Middleware Tutorial

Vulnerability Assessment and Secure Coding Practices for Middleware Tutorial (1/2) (90 mins)
James A. Kupsch and Prof. Barton P. Miller

Security is crucial in the software that we develop and use. This tutorial is relevant to anyone wanting to learn about assessing software for security flaws and for developers wishing to minimize security flaws in software they develop.

We share our experience in vulnerability assessment of real-world grid middleware. You will learn skills critical for developers and analysts concerned about software security, and the importance of independent vulnerability assessment.

The tutorial covers a process to actively discover vulnerabilities. We show how to gather information about a system which is used to direct the search for vulnerabilities, and how to integrate vulnerability assessment and discovery into the development cycle.

Next, we examine coding practices to prevent vulnerabilities by describing more than 20 types of vulnerabilities with examples of how they commonly arise, and techniques to prevent them. Most examples are in C, C++, Perl, and the standard C and POSIX APIs.

This tutorial teaches critical assessment and coding skills. In addition, it discusses policy issues relating to independent auditing, vulnerability reporting, and integrating security fixes into the software release cycle.
The security of software is becoming increasingly important to anyone who uses or develops it. This tutorial teaches developers and assessors how to proactively reduce the number of vulnerabilities in their software. Just as independent QA testing is essential for assessing software reliability, testing for security is essential for assuring software security. Even projects that architect their software with security in mind still need independent vulnerability assessment to detect design flaws or coding problems that can arise in any project. Testing for security is an essential part of the development process and a unique skill that requires training.

This tutorial is an outgrowth of our experience in performing vulnerability assessment of a variety of grid middleware, which includes Condor from the University of Wisconsin, the Storage Resource Broker from the San Diego Supercomputer Center, MyProxy from the National Center for Supercomputer Applications, and EGEE's glexec. The tutorial teaches the processes and skills that we developed and used in these activities.

This tutorial is relevant to anyone who wants to learn about analyzing software for security flaws and for developers wishing to minimize security flaws in software that they develop. It covers the two sides of security: the offensive--how to find problems through the use of proactive vulnerability assessment; and the defensive--how to prevent problems by showing many types of vulnerabilities that occur in code and what techniques can be used to prevent them.

The target audience for this tutorial is anyone involved with the development of software, wishing to assess the security of software, or managing the software development process. To gain maximum benefit from this tutorial, attendees should be familiar with the process of developing software and the C programming language, along with a basic knowledge of the standard C library and the POSIX API.

This tutorial does not assume any prior knowledge of security assessment or vulnerabilities. Some of the examples include less common APIs, or are in a programming language other than the C programming language. In these instances, enough explanation is given so the attendee unfamiliar with the topic should be able to understand the concepts.

The first part of this tutorial explains how to perform a vulnerability assessment. Our process is based on a deep assessment of the software, done by one who is working in cooperation with the development team and has access to source code, internal documents and developers. We emphasize understanding of the process of vulnerability assessment and developing the skills needed to conduct such an assessment.

The first step of a vulnerability assessment is to gain an in-depth understanding of the system. Without an understanding of how it works, it is impossible to know what are the critical assets and what are the threats to these assets. To do this, the tutorial shows a process to gather and document this information by performing an architectural, resource and privilege analysis. These steps are completed by meeting with the developers, reviewing design documents and end-user documentation, using the system, and looking at the code.

The architectural analysis consists of discovering and documenting the high level structures of the system: functionality, hosts, configuration parameters, processes, user interaction, interactions between processes, interactions with external systems, other communication channels, resources controlled by processes, and trust between components.

The resource and privilege analysis is the process of discovering and documenting the objects that the system can manipulate, such as in-memory data structures, database records, files, CPU cycles, and physical devices controlled by the computer. It also documents what actions can be performed on the resources in the system. The privilege analysis documents the privilege model defined by the system itself, and the configuration of privileges in the underlying operating system and external applications, such as databases.

The tutorial then shows how to create data flow diagrams from the results of the prior analyses. These diagrams contain much of the information collected earlier in a succinct fashion that allows the analyst to easily comprehend the system.

The tutorial then covers the process of performing a component analysis, which is looking for vulnerabilities in components of the system. Since it is not realistic to completely verify the security of the system, the tutorial shows how to use the previous steps of the analysis to focus the search to find both those that are likely to be easily found by outside attackers, and also those vulnerabilities that can lead to higher value targets such as the compromise of the host operating system or a subversion of the privilege system. Information in the second part of the tutorial explains how to look for specific types of vulnerabilities.

The tutorial also describes how to integrate the results of the vulnerability assessment process into the software development process, including writing vulnerability reports, the vulnerability disclosure process, fixing vulnerabilities, and releasing security updates.

The second part of this tutorial focuses on vulnerabilities. It features several interactive secure coding quizzes where the audience is challenged to find as many vulnerabilities as they can in short code fragments. What the audience finds (and does not find) are then discussed.

This part also contains a discussion of the most common vulnerabilities and is valuable to both developers and security assessors. Descriptions of each vulnerability are presented with examples. It is shown how the vulnerability typically occurs within code, pointing out APIs or techniques that commonly result in the vulnerability, and also how the vulnerability can be mitigated or eliminated through the use of other techniques or APIs. The causes and types of vulnerabilities covered include:

• Lack of data validation
• Error Handling
• Buffer overflows
• Numeric parsing
• Integer vulnerabilities
• Race conditions
• Injection attacks
• Format string attack
• Command injection
• SQL injection
• Cross-site scripting (XSS)
• Directory traversals
• Memory management attacks
• Race conditions
• Denial of service
• Insecure permissions
• Not dropping privileges
• Information leaks

Genesis II (90 mins

Genesis II (90 mins)

Genesis II is the first integrated implementation of the standards and profiles coming out of the OGF Open Grid Services Architecture (OGSA) Working Group [2-4]. Genesis II is a complete set of Grid services for users and applications which not only follows our maxim – “by default the user should not have to think” – but is also a from-scratch implementation of the standards and profiles – not a wrapping of existing artifacts. Genesis II is open source under the Apache license.

Genesis II is open source under the Apache license.
Genesis II was created to address a number of needs and answer various questions about emerging Grid technology. These included
• the need for a production Grid system with which to provide compute and data Grid capabilities to various partner groups and research projects,
• the desire to have a fully functional Grid framework on which further Grid research could be performed,
• and the desire to “test drive” the various specifications making their way through various standardization organizations to both vet and better understand those specifications, both in isolation, and together as a whole.
Genesis II is fully operational in a production environment at the University of Virginia. It supports both data and compute Grid functionality. Users can interact with Genesis II via both a familiar command-line interface (based largely on common *NIX commands such as ls, cat, cp, etc.), through a Grid aware FTP daemon, via an IFS file system in Windows, and in Linux via a FUSE [5] file system driver that maps the Genesis namespace into the local file system namespace. Genesis II has OGSA-BES [1, 4] implementations for both Windows and Linux, as well as a simple job manager that implements a simple queue. To run jobs users can submit JSDL documents to a queue (described shortly) or run them directly on a BES resource.

Agenda:
The proposed tutorial will focus on installing and using Genesis II. The tutorial will begin with an overview of Genesis II, how the standards fit into Genesis II, and the driving architectural theme – a single shared directory system that maps human paths to EPR’s. We will then install Genesis II on participant laptops (if they have them and are willing), demonstrate how to mount and use the FUSE and Windows IFS interfaces to Genesis II, how to run jobs, run sets of jobs, and share data with other users.

Porting applications to the Grid using the EDGeS Application Development Methodology

Porting applications to the Grid using the EDGeS Application Development Methodology (90 mins)
Tamas Kiss, Ad Emmen

Abstract:
A Grid can be a powerful number crunching machine bringing the power of thousands of processors to an application developer's finger tips. Although current Grid infrastructures offer significant amount of resources to run computation and data intensive applications, some scenarios still overgrow the capabilities of existing
Grids. Unfortunately, the two main types of Grids infrastructures, Service and Desktop Grid systems, were not interoperable until recently. The European EDGeS
project is currently developing a bi-directional bridge connecting this diverse collection of resources.

Programming an application for a Grid is not easy. Current Grid application development efforts very often use ad-hoc approaches only when porting the applications. Developers do not follow any suggested methodology and this may result
is poorly documented systems that do not fulfill user expectations. In order to avoid this trap, support application developers and provide guidelines when porting
an application to the EDGeS Grid platform, the EDGeS Application Development Methodology (EADM) has been specified.

This tutorial introduces the EDGeS Grid platform (EGEE extended with BOINC and XtremWeb Desktop Grids) and the EDGeS Application
Development Methodology. So far 12 applications from fields of bio-science, chemistry, physics, engineering, e-market, etc. have been ported to EDGeS. Case studies of tools that make the application development easier and examples for applications that have been ported to EDGeS using the EADM
are presented.
Target Audience:
Application developers that want to port an application to Desktop Grids. Representatives of EGEE user communities who want to port existing EGEE applications to the EDGeS infrastructure.

Usage Control for Next Generation Grids

Usage Control for Next Generation Grids (1/2) (90 mins)
Alvaro Arenas (STFC RAL, UK); Lorenzo Blasi (HP, Italy); Giovanni Cortese (Interplay, Italy); Bruno Crispo (VUA, Netherlands, and Univ. Trento, Italy); Fabio Martinelli (CNR, Italy); Philippe Massonet

Usage control is an authorisation framework that extends traditional access control by controlling data access as well as usage. This tutorial presents how to model and implement usage control for Grids. The tutorial comprises five parts: an introduction to the usage control model; an OGSA-based architecture for usage control; usage control policies in XACML; an alternative policy language for usage control in Grids; and two case studies showing the application of usage control in Grid systems
The “Usage Control for Next Generation Grids” tutorial consists of the following six talks:

Usage Control for Grids.
The usage control model (UCON) is a new access control paradigm proposed by Park and Sandhu that encompasses and extends different existing models. Its main novelty, in addition to the unification view, is based on continuity of usage monitoring and mutability of attributes. This talk introduces the usage control model and highlights the challenges in controlling resource usage in Grid systems.

An Architecture for Usage Control in Grids.
This talk describes an OGSA-based architecture for implementing usage control for Grids. The architecture has been developed in the EU GridTrust project, extending the current Grid Security Infrastructure (GSI) to deal with usage control.

Usage Control Policies in XACML.
XACML is the standard language for access control in distributed systems. This talk presents how XACML has been extended and used for the specific purpose of expressing and supporting usage control in Grid applications. Particular emphasis will be given to performance and scalability issues. Furthermore, the talk will address the issue of the interaction of scheduling with access control.

Usage Control in Action: Controlling Service Usage in a Grid-Based Content Management System.
This talk presents a case study of the application of usage control based on XACML. The case study is a grid-based content management system that supports a distributed organization in the execution of collaborative projects, aiming at the production of a complex ‘digital’ product. The production process is structured along a workflow such as a software production process or a web / content publishing process.

PolPA: A Usage Control Policy Language for Grids.
Policies languages as XACML cannot express the full potentiality of usage control models such as UCON. This talk shows an alternative policy language, PolPA, that has been designed specifically for expressing usage control policies and has been tailored for dealing with Grids. Since it is based on Process Algebras, PolPA is very expressive and allows to encode all the core models that have been defined by Park and Sandhu. This talk also describes a reference architecture to enforce PolPA in Grid systems.

Usage Control in Action: Controlling Resource Usage in a Grid-Based Supply Chain.
This talk presents a case study of the application of usage control based on PolPA. The case study is a transportation supply chain which exploits Grid services for optimizing both the delivery and cost of each customer order. Each transporter uses a Grid-based computing service to re-optimize the routes of its vehicles’ fleet after the addition of each new transportation task. Transporters submit their routing jobs to a Grid portal supported by their association. Local usage control policies allow computational service providers to protect their resources and other transporters’ data.

Vulnerability Assessment and Secure Coding Practices for Middleware Tutorial

Vulnerability Assessment and Secure Coding Practices for Middleware Tutorial (1/2) (90 mins)
James A. Kupsch and Prof. Barton P. Miller

Security is crucial in the software that we develop and use. This tutorial is relevant to anyone wanting to learn about assessing software for security flaws and for developers wishing to minimize security flaws in software they develop.

We share our experience in vulnerability assessment of real-world grid middleware. You will learn skills critical for developers and analysts concerned about software security, and the importance of independent vulnerability assessment.

The tutorial covers a process to actively discover vulnerabilities. We show how to gather information about a system which is used to direct the search for vulnerabilities, and how to integrate vulnerability assessment and discovery into the development cycle.

Next, we examine coding practices to prevent vulnerabilities by describing more than 20 types of vulnerabilities with examples of how they commonly arise, and techniques to prevent them. Most examples are in C, C++, Perl, and the standard C and POSIX APIs.

This tutorial teaches critical assessment and coding skills. In addition, it discusses policy issues relating to independent auditing, vulnerability reporting, and integrating security fixes into the software release cycle.
The security of software is becoming increasingly important to anyone who uses or develops it. This tutorial teaches developers and assessors how to proactively reduce the number of vulnerabilities in their software. Just as independent QA testing is essential for assessing software reliability, testing for security is essential for assuring software security. Even projects that architect their software with security in mind still need independent vulnerability assessment to detect design flaws or coding problems that can arise in any project. Testing for security is an essential part of the development process and a unique skill that requires training.

This tutorial is an outgrowth of our experience in performing vulnerability assessment of a variety of grid middleware, which includes Condor from the University of Wisconsin, the Storage Resource Broker from the San Diego Supercomputer Center, MyProxy from the National Center for Supercomputer Applications, and EGEE's glexec. The tutorial teaches the processes and skills that we developed and used in these activities.

This tutorial is relevant to anyone who wants to learn about analyzing software for security flaws and for developers wishing to minimize security flaws in software that they develop. It covers the two sides of security: the offensive--how to find problems through the use of proactive vulnerability assessment; and the defensive--how to prevent problems by showing many types of vulnerabilities that occur in code and what techniques can be used to prevent them.

The target audience for this tutorial is anyone involved with the development of software, wishing to assess the security of software, or managing the software development process. To gain maximum benefit from this tutorial, attendees should be familiar with the process of developing software and the C programming language, along with a basic knowledge of the standard C library and the POSIX API.

This tutorial does not assume any prior knowledge of security assessment or vulnerabilities. Some of the examples include less common APIs, or are in a programming language other than the C programming language. In these instances, enough explanation is given so the attendee unfamiliar with the topic should be able to understand the concepts.

The first part of this tutorial explains how to perform a vulnerability assessment. Our process is based on a deep assessment of the software, done by one who is working in cooperation with the development team and has access to source code, internal documents and developers. We emphasize understanding of the process of vulnerability assessment and developing the skills needed to conduct such an assessment.

The first step of a vulnerability assessment is to gain an in-depth understanding of the system. Without an understanding of how it works, it is impossible to know what are the critical assets and what are the threats to these assets. To do this, the tutorial shows a process to gather and document this information by performing an architectural, resource and privilege analysis. These steps are completed by meeting with the developers, reviewing design documents and end-user documentation, using the system, and looking at the code.

The architectural analysis consists of discovering and documenting the high level structures of the system: functionality, hosts, configuration parameters, processes, user interaction, interactions between processes, interactions with external systems, other communication channels, resources controlled by processes, and trust between components.

The resource and privilege analysis is the process of discovering and documenting the objects that the system can manipulate, such as in-memory data structures, database records, files, CPU cycles, and physical devices controlled by the computer. It also documents what actions can be performed on the resources in the system. The privilege analysis documents the privilege model defined by the system itself, and the configuration of privileges in the underlying operating system and external applications, such as databases.

The tutorial then shows how to create data flow diagrams from the results of the prior analyses. These diagrams contain much of the information collected earlier in a succinct fashion that allows the analyst to easily comprehend the system.

The tutorial then covers the process of performing a component analysis, which is looking for vulnerabilities in components of the system. Since it is not realistic to completely verify the security of the system, the tutorial shows how to use the previous steps of the analysis to focus the search to find both those that are likely to be easily found by outside attackers, and also those vulnerabilities that can lead to higher value targets such as the compromise of the host operating system or a subversion of the privilege system. Information in the second part of the tutorial explains how to look for specific types of vulnerabilities.

The tutorial also describes how to integrate the results of the vulnerability assessment process into the software development process, including writing vulnerability reports, the vulnerability disclosure process, fixing vulnerabilities, and releasing security updates.

The second part of this tutorial focuses on vulnerabilities. It features several interactive secure coding quizzes where the audience is challenged to find as many vulnerabilities as they can in short code fragments. What the audience finds (and does not find) are then discussed.

This part also contains a discussion of the most common vulnerabilities and is valuable to both developers and security assessors. Descriptions of each vulnerability are presented with examples. It is shown how the vulnerability typically occurs within code, pointing out APIs or techniques that commonly result in the vulnerability, and also how the vulnerability can be mitigated or eliminated through the use of other techniques or APIs. The causes and types of vulnerabilities covered include:

• Lack of data validation
• Error Handling
• Buffer overflows
• Numeric parsing
• Integer vulnerabilities
• Race conditions
• Injection attacks
• Format string attack
• Command injection
• SQL injection
• Cross-site scripting (XSS)
• Directory traversals
• Memory management attacks
• Race conditions
• Denial of service
• Insecure permissions
• Not dropping privileges
• Information leaks

Data Management

Data Management is the most significant challenge to many user communities within EGEE. It also represents one of the main uses of e-infrastructure - the large scale computational analysis of large volumes of data. Many communities are having to develop new techniques and use new services to deal with the 'data deluge' coming from their research activities. Now that the e-infrastructure exists to store and analyse the data, the next challenge for many end-users is how to derive information and gain knowledge from the raw data to meet their research objectives.

The presentations cover two broad areas - the standards being used to provide consistent access to the data management services and the services that form the operational e-infrastructure. These presentations will include:
