Electronic Signatures and Infrastructures (ESI) - General Policy Requirements for Trust Service Providers
The present document specifies general policy requirements relating to trust service providers (TSPs) that are
independent of the type of TSP. It defines policy requirements on the operation and management practices of TSPs.
Other specifications refine and extend these requirements as applicable to particular forms of TSP. The present
document does not specify how the requirements identified can be assessed by an independent party, including
requirements for information to be made available to such independent assessors, or requirements on such assessors.
NOTE: See ETSI EN 319 403 [i.6]: "Electronic Signatures and Infrastructures (ESI); Requirements for
conformity assessment bodies assessing Trust Service Providers".

Lack of trust, in particular because of a perceived lack of security, makes consumers, businesses and administrations hesitate to carry out transactions electronically and to adopt new services. Trust service providers are often an essential element to establish trust between parties transacting electronically, particularly in open public networks, and can be used, for example, to provide trusted identity information and help establish secure communications between transacting parties. Examples of such trust service providers are issuers of public key certificates, time-stamping service providers, providers of remote electronic signature generation or validation services. For participants of electronic commerce to have confidence in the security of these trust services they need to have confidence that the trust service providers (TSPs) have established a set of procedures, processes and security measures in order to minimize the operational and financial threats and risks associated. The present document specifies baseline policy requirements on the operation and management practices of TSP regardless the service they provide. Other standards, addressing particular type of trust service, can build on the present document to identify supplement requirements for particular type of trust service. SIST EN 319 401 V2.1.1:2016

ETSI ETSI EN 319 401 V2.1.1 (2016-02) 8 4 Overview Trust services may encompass but should not be limited to the issuance of public key certificates, provision of registration services, time-stamping services, long term preservation services, e-delivery services and/or signature validation services. These policy requirements are not meant to imply any restrictions on charging for TSP services. The requirements are indicated in terms of the security objectives followed by more specific requirements for controls to meet those objectives where considered necessary to provide the necessary confidence that those objectives will be met. When implementing controls of clause 7, ISO/IEC 27002:2013 [i.3] should be applied. NOTE: The details of controls required to meet an objective is a balance between achieving the necessary confidence whilst minimizing the restrictions on the techniques that a TSP can employ in providing services. 5 Risk Assesment The TSP shall carry out a risk assessment to identify, analyse and evaluate trust service risks taking into account business and technical issues.
The TSP shall select the appropriate risk treatment measures, taking account of the risk assessment results. The risk treatment measures shall ensure that the level of security is commensurate to the degree of risk. NOTE: See ISO/IEC 27005 [i.5] for guidance on information security risk management as part of an information security management system. The TSP shall determine all security requirements and operational procedures that are necessary to implement the risk treatment measures chosen, as documented in the information security policy and the trust service practice statement (see clause 6). The risk assessment shall be regularly reviewed and revised. The TSP management shall approve the risk assessment and accept the residual risk identified. 6 Policies and practices 6.1 Trust Service Practice statement The TSP shall specify the set of policies and practices appropriate for the trust services it is providing. These shall be approved by management, published and communicated to employees and external parties as relevant. The TSP shall have a statement of the practices and procedures for the trust service provided. NOTE: The present document makes no requirement as to the structure of the trust service practice statement. In particular: a) The TSP shall have a statement of the practices and procedures used to address all the requirements identified for the applicable TSP policy. b) The TSP's trust service practice statement shall identify the obligations of all external organizations supporting the TSP services including the applicable policies and practices. c) The TSP shall make available to subscribers and relying parties its practice statement, and other relevant documentation, as necessary to assess conformance to the service policy. d) The TSP shall have a management body with overall responsibility for the TSP with final authority for approving the TSP practice statement.

Terms and conditions shall be made available through a durable means of communication. This information shall be available in a readily understandable language. It may be transmitted electronically. 6.3 Information security policy The TSP shall define an information security policy which is approved by management and which sets out the organization's approach to managing its information security.

Building trust in the online environment is key to economic and social development. Lack of trust, in particular because
of a perceived lack of security, makes consumers, businesses and administrations hesitate to carry out transactions
electronically and to adopt new services. Trust service providers are often an essential element to establish trust
between parties transacting electronically, particularly in open public networks, and can be used, for example, to
provide trusted identity information and help establish secure communications between transacting parties. Examples of
such trust service providers are issuers of public key certificates, time-stamping service providers, providers of remote
electronic signature generation or validation services.
For participants of electronic commerce to have confidence in the security of these trust services they need to have
confidence that the trust service providers (TSPs) have established a set of procedures, processes and security measures
in order to minimize the operational and financial threats and risks associated.
The present document specifies baseline policy requirements on the operation and management practices of TSP

Introduction
Building trust in the online environment is key to economic and social development. Lack of trust, in particular because
of a perceived lack of security, makes consumers, businesses and administrations hesitate to carry out transactions
electronically and to adopt new services. Trust service providers are often an essential element to establish trust
between parties transacting electronically, particularly in open public networks, and can be used, for example, to
provide trusted identity information and help establish secure communications between transacting parties. Examples
of such trust service providers are issuers of public key certificates, time-stamping service providers, providers of
remote electronic signature generation or validation services.
For participants of electronic commerce to have confidence in the security of these trust services they need to have
confidence that the trust service providers (TSPs) have established a set of procedures, processes and security measures
in order to minimize the operational and financial threats and risks associated.
The present document specifies baseline policy requirements on the operation and management practices of TSP
regardless the service they provide. Other standards, addressing particular type of trust service, can build on this
standard to identify supplement requirements for particular type of trust service.
The present document is aiming to meet the general requirements of the international community to provide trust and
confidence in electronic transactions including, amongst others, applicable requirements from Regulation (EU)
No 910/2014 [i.2] and those from CA Browser Forum [i.4].

Other specifications refine and extend these requirements as applicable to particular forms of TSP. The present
