Requirements gathering for secure access and use of a generic grid
Currently we are seeking assistance to build a list of use-cases that will lead us towards a set of functional requirements for access management and security for a generic grid. (The 'generic grid' is a production grid, with production applications and a set of users with a wide variety of skills and interests.) We are trying to avoid any limitations with current technologies and to think clearly about requirements before considering technology. This is an early workpackage for the ESP-GRID project.

Use Cases
* use cases for a generic grid
Top-level requirements described below under:
- Grid AAA (A) requirements (authentication authorisation and accounting, and auditing)
- Grid protection of data requirements (privacy, confidentiality, integrity, digital rights management)
- Grid operational characteristics (trust, performance and scalability, manageability incl. architectural components, interoperability, assurance)
- Additional requirements which need a better home (single log-on, policy exchange)
Grid AAA requirements (authentication authorisation and accounting, and auditing) described under:
Authentication AuthN
Include Note
identity, anonymity, pseudonimity (secure anonymous communication), credential lifespan and renewal (short-term credentials), assurance levels (SEE ALSO Operational Characteristics), revocation, policies, documentation, usability, trust (SEE ALSO Operational Characteristics) and responsibility, secure roaming
Insert definition here and requirements follow...
Authorisation AuthZ
Include Note
identity, grouping users/roles, authorisation levels, revocation, attributes, policies, 'transparency', privacy, logging, credentials, fault tolerance, delegation, XXXXmore...
Insert definition here and requirements follow...
Accounting
Include Note
accurate billing and metering, (operational costs, service levels), monitoring or logging, resource and end entity - secure logging, scheduling and resource management. SEE ALSO Grid Auditing
Insert definition here and requirements follow...
Auditing
Include Note
'Accounting as a security component', monitoring or secure logging (resource access decisions, policies, policy changes, resource implication of policies), audit logs, intrusion detection, forensics, diagnostics, audit trail (AuthN and AuthZ). SEE ALSO GridAccounting
Insert definition here and requirements follow...
Grid protection of data requirements described under:
Include Note
.
Privacy
Include Note
use of data, (supported by confidentiality mechanisms including AuthZ), significant for health data etc.
Definition and requirements follow...
Confidentiality
Include Note
supported by access control within systems and encryption between and within systems, signalling policies, supports privacy, protects sensitive data
Definition and requirements follow...
Integrity
Include Note
provenance (i.e. maintaining integrity of chains/groups of related data), message integrity
Definition and requirements follow...
Digital rights management (DRM)
Include Note
XXXX
Definition and requirements follow...
Grid operational characteristics described under:
Include Note
.
Trust
Include Note
between collaborative organisations, policy framework, infrastructure
Definition and requirements follow...
Performance and scalability
Include Note
delegation(policies and trust frameworks, virtual grids)
Definition and requirements follow...
Manageability incl. architectural components
Include Note
policies, identity management, intrusion detection, anti-virus (i.e. architectural components - others include platform security, system level security design, firewall traversal).
Definition and requirements follow...
Interoperability
Include Note
between grid environments, policies
Definition and requirements follow...
Assurance
Include Note
(is this the same as we understand?), security assurance level
Definition and requirements follow...
- described under:
Other Requirements
Additional requirements which need a better home include:
.
Single log-on
Include Note
delegate an entity's rights subject to policy Defintion and requirements follow...
Policy exchange
Include Note
establish a negotiated security context
