1 Introduction and Definitions
To fulfil its mission, it is necessary for the Grid to protect its resources. This document presents the policy regulating those activities of Grid participants related to the security of Grid services and Grid resources.
The word Grid, when italicised in this document, means any project or operational infrastructure which uses grid technologies and decides to adopt this policy.
The other italicised words used in this document are defined as follows:
- Policy is interpreted to include rules, responsibilities and procedures specified in this document together with all those in other documents which are required to exist by stipulations in this document.
- Aparticipant is any entity providing, using, managing, operating, supporting or coordinating one or more Grid service(s).
- Aservice is any computing or software system, based on grid technologies, which provides access to, information about or controls resources.
- A resource is the equipment and software required to run a service on theGrid, and any data
held on the service.
- Included in the definition of equipment are processors and associated disks, tapes and other peripherals, storage systems and storage media, networking components and interconnecting media.
- Included in the definition ofsoftware are operating systems, utilities, compilers and other general purpose applications, any software required to operate any equipment, software and middleware released and/or distributed by the Grid and any software required to support any application associated with Virtual Organisations or other authorized users.
- Included in the definition of data are data required to operate any equipment defined as a resource, data required to operate any service, data intended to be processed or produced by any software defined as a resource, and any application data.
- Management is the collection of the various boards, committees, groups and individuals mandated to oversee and control the Grid.
- A user is an individual who has been given authority to access and use Grid resources.
- A Virtual Organisation (or VO) is a grouping of users and optionally resources, often not bound to a single institution, who, by reason of their common membership and in sharing a common goal, are given authority to use a set of resources.
- Included in the definition of a VO are cases where Grid resources are offered to individual users who are not members of a formal VO. These users are, however, often associated with an applicationcommunity, and these communities, or even a single user, are treated in this document as though they are a VO.
- VO management is the collection of various individuals and groups mandated to oversee and control a VO.
- A site is an entity having administrative control of resources provided to the Grid. This may be at one physical location or spread across multiple physical locations.
- Site management is the collection of various individuals and groups mandated to oversee and control a site.
- A resource administrator is the person responsible for installing, operating, maintaining and supporting one or more resource(s) at a site.
This policy gives authority for actions which may be carried out by certain individuals and bodies and places responsibilities on all participants.
This policyapplies to all participants.
Every site participating in the Grid autonomously owns and follows their own local security policies with respect to the system administration and networking of all the resources they own, including resources which are part of the Grid. This policy augments local policies by setting out additional Grid-specific requirements.
1.4 Additional Policy Documents
Appendix 1 defines additional policy documents which must exist for a proper implementation of this policy. These documents are referred to in section 2.
An accompanying document for each Grid adopting this policy must define the Grid-specific locations and version numbers of their approved and adopted additional policy documents.
1.5 Ownership and Maintenance
This policy is prepared and maintained by the Security Policy Group, approved by management and thereby endorsed and adopted by the Grid as a whole.
This policy will be revised by the Security Policy Group as required and resubmitted for formal approval and adoption whenever significant changes are needed.
The most recently approved version of this document is available at https://documents.egi.eu/document/86
2 Roles and Responsibilities
This section defines the roles and responsibilities of participants.
2.1 Grid Management
The management provides, through the adoption of this policy and through its representations on the various approving bodies of the Grid, the overall authority for the decisions and actions resulting from this policy including procedures for the resolution of disputes.
2.2 Grid Security Officer and Grid Security Operations
Themanagement must appoint a Grid Security Officer who leads and/or coordinates the team providing the operational security capability, known as Grid Security Operations.
The Grid Security Officer may, in consultation with Grid Security Operations, management and other appropriate persons, require actions by participants as are deemed necessary to protect resources from or contain the spread of grid security incidents.
The responsibilities of Grid Security Operations include:
- The maintenance of contact details of security personnel at each participating site and the facilitation of Grid-related communications between them.
- Handling of operational security problems as they arise.
- Providing incident response teams who will act according to the Security Incident Response Policy .
- Handling requests for exceptions to this policy as described in section 5.
2.3 Virtual Organisation Management
The responsibilities of the VO management include:
2.3.1 VO Security Policies
VOs are required to abide by the Virtual Organisation Operations Policy  and the Virtual Organisation Registration Security Policy . They must have a VO Acceptable Use Policy (AUP) and ensure that only individuals who have agreed to abide by the Grid AUP  and the VO AUP are registered as members of the VO.
2.3.2 User Registration and VO Membership Service
The user registration procedure of the VO is required to be consistent with the Virtual Organisation Membership Management Policy . Approval to join the VO must be restricted to individuals who are recognised as having legitimate rights to membership and who agree to be bound by the AUPs. A VO membership service must be provided with appropriate interfaces to generate authentication, authorization and other identity mapping data for the services running on the sites. VOs are required to maintain the accuracy of the information held and published about their members, and to promptly remove individuals who lose their right to such membership.
2.3.3 VO-specific Resources
VOs are responsible for ensuring that their software does not pose security threats, that access to their databases is secure and is sufficiently monitored, that their stored data are compliant with legal requirements, and that VO-specific services are properly monitored and do not compromise sites or resources.
2.3.4 Applying Sanctions to Users
VOs are responsible for promptly investigating reports of users failing to comply with the AUPs and for taking appropriate action to ensure compliance in the future, as defined in section 6.
All users must be members of one of the registered VOs or application communities.
The responsibilities of users include:
2.4.1 Acceptable Use
Users must accept and agree to abide by the Grid Acceptable Use Policy  and the VO AUP when they register or renew their registration with a VO.
Users must be aware that their work may utilise shared resources and may therefore affect the work of others. They must show responsibility, consideration and respect towards other users in the demands they place on the Grid.
Users must have a suitable authentication credential issued as approved by the Grid. They must ensure that others cannot use their credentials to masquerade as them or usurp their access rights. Users may be held responsible for all actions taken using their credentials, whether carried out personally or not. No intentional sharing of credentials for Grid purposes is permitted.
Users must be aware that their jobs will often use resources owned by others. They must observe any restrictions on access to resources that they encounter and must not attempt to circumvent such restrictions.
Application software written or selected by users for execution on resources must be directed exclusively to the legitimate purposes of their VO. Such software must respect the autonomy and privacy of the host sites on whose resources it may run.
2.5 Site Management
The responsibilities of the Site management include:
2.5.1 Site Operations Policy
Sites hosting resources are required to provide reliable and well managed services and abide by the Grid Site Operations Policy . Sites must abide by the Site Registration Security Policy  and the Grid Security Traceability and Logging Policy .
2.5.2 Mitigating Risks
Sites acknowledge that participating in the Grid increases the risk from security incidents, to both
Grid and non-Grid hosts on each site. Sites are responsible for mitigating this risk.
2.5.3 Incident Response
Sites accept the duty to cooperate with Grid Security Operations and others in investigating and resolving security incidents, and to take responsible action as necessary to safeguard resources during an incident in accordance with the Security Incident Response Policy .
2.5.4 Access Control
Access to all resources is controlled by a common grid security infrastructure which includes both authentication and authorization components. The global components of this infrastructure, e.g. as specified in the Approval of Certification Authorities , must be deployed by all sites and resources. The deployment of additional local security measures is permitted should the local security policies of the site or resource administration require this.
2.5.5 Notification of Legal Compliance Issues
If exceptions or extensions to this policy are required because of local legislation, the site must inform the Grid Security Officer(see section 5).
2.6 Resource Administrators
In addition to their local site policy resource administrators must ensure their implementations of services comply with this policy.
The responsibilities of resource administrators include:
2.6.1 Notifying Site Personnel
Resource administrators are responsible for ensuring that their site is registered with the Grid and that all appropriate personnel concerned with security or system management at their site are notified of and accept the requirements of this policy before offering any services.
2.6.2 Resource Administration
The resource administrators are responsible for the installation and maintenance of resources assigned to them, including ongoing security, and subsequently for the quality of the operational service provided by those resources.
3 Physical Security
All the requirements for the physical security of resources are expected to be adequately covered by each site’s local security policies and practices. These should, as a minimum, reduce the risks from intruders, fire, flood, power failure, equipment failure and environmental hazards.
Stronger physical security may be required for equipment used to provide certain critical services such as VO membership services or credential repositories. The technical details of such additional requirements are contained in the procedures for operating and approving such services.
4 Network Security
All the requirements for the networking security of resources are expected to be adequately covered by each site’s local security policies and practices. These should, as a minimum, reduce the risks from intruders and failures of hardware or software by implementing appropriate firewall protection, by the timely application of all critical security-related software patches and updates, and by maintaining and observing clearly defined incident response procedures.
It is Grid policy to minimise the security risk exposed by applications which need to communicate across the Internet; even so, the peripheral firewall on every participating site may be required to permit the transit of inbound and outbound packets to/from certain port numbers between a number of external and internal hosts in order to run or reach services.
5 Limits to Compliance
Exceptions to compliance with this policy include, but are not limited to, the following:
Wherever possible, Grid policies and procedures are designed so that they may be applied uniformly across all sites andVOs. If this is not possible, for example due to legal or contractual obligations, exceptions may be made. Such exceptions must be justified in a document submitted to the Grid Security Officer for authorisation and, if required, approval at the appropriate level of management.
In exceptional circumstances it may be necessary for participants to take emergency action in response to some unforeseen situation which may violate some aspect of this policy for the greater good of pursuing or preserving legitimate Grid objectives. If such a policy violation is necessary, the exception should be minimised, documented, time-limited and authorised at the highest level of the management commensurate with taking the emergency action promptly, and the details notified to the Grid Security Officer at the earliest opportunity.
6 Sanctions, Liability, Disputes and Intellectual Property Rights
Sites or resource administrators who fail to comply with this policy in respect of a service they are operating may lose the right to have that service instance recognised by the Grid until compliance has been satisfactorily demonstrated again.
Users who fail to comply with this policy may lose their right of access to and/or collaboration with the Grid, and may have their activities reported to their home institute or, if those activities are thought to be illegal, to appropriate law enforcement agencies.
VOs which fail to comply with this policy,together with all the users whose rights with respect to the Grid derives from that VO, may lose their right of access to and/or collaboration with the Grid.
The issues of liability, dispute resolution and intellectual property rights, all of which may be Grid-specific, should be addressed in the additional policy documents.
