SISP policy

System Interconnect Security Policy (“SISP”)

1.      Overview

 

UKCloud provides an infrastructure to enable clients to host data and applications in a secure and resilient manner. The UKCloud platforms are designed to host data within environments suitable for both OFFICIAL and OFFICIAL SENSITIVE data (as per the Government Security Classification Policy) and will meet the accreditation and assurance requirements associated with data at these levels.

 

The nature of cloud services is such that there are distinct separations of ownership of the overall environment. Essentially, UKCloud provides and owns the infrastructure that supports the applications and data, whilst the clients themselves own and have responsibility for their individual applications, system configurations and their associated data.

 

This separation of ownership also includes a separation of security ownership, accountability and responsibility. The UKCloud environment will meet the specifications of the Baseline Control Set (BCS) and the recommendations of the current Security Policy Framework (SPF) as well as achieving applicable accreditations, certifications and supporting assurance validations. To meet these criteria, it is necessary to identify the overall security requirement and then to agree the ownership, accountability and responsibility boundaries between UKCloud and its clients.

 

This System Interconnect Security Policy (“SISP”) is the formal top-level security document that identifies those aspects that are within the remit of the UKCloud Security Officer and those that are within the remit of the data-owning client’s Security Officer or SIRO. More specific information can be found within the SyOPs sections of the appropriate RMADS issued for each individual UKCloud service.

 

Acceptance of this SISP is agreement to and compliance with the separation of security requirements and responsibilities.

2.      Security Policy

 

2.1        The SISP, while being the overarching security policy for the UKCloud environment, does not address individual security requirements in detail. UKCloud shall provide corresponding security documentation for the infrastructure and the client shall provide similar documentation for their individual applications and data.  

 

2.2        UKCloud has communicated the detailed security requirements of its IT services within the RMADS documentation of each service. The RMADS documentation is made available to the client prior to their deployment and consumption of the UKCloud service, and the client remains at all times responsible for full compliance with the requirements of the SyOPs contained within the corresponding RMADS documentation.  

 

2.3        Each party (UKCloud and the end client) shall make the other party aware of any salient   aspects of their own security policy.

 

2.4        The SISP and UKCloud Security Policy shall be reviewed annually as a minimum, and in the event of any security incident. Changes, if required, shall be informed to the client. It is expected that the client shall also review their security policy at least annually and any relevant changes will be informed to UKCloud promptly.  

3.      Organisation of Information Security

 

3.1        UKCloud shall have designated Risk Owners and Security Officers with an overall Responsible Individual designated to own the security regime of each. The client shall have their own designated personnel in the relevant roles to own and co-ordinate their own security activities.

 

3.2        Formal processes shall exist between UKCloud and its partners to co-ordinate their          security activities. The client shall ensure that relevant co-ordination exists with their areas of        responsibility. Liaison and co-ordination between the client and UKCloud shall be agreed as       part of the formal contract using this System Interconnect Security Policy.

 

3.3        The initial configuration and composition of the overall system shall be agreed between UKCloud and the client. Any subsequent changes or additions to the system will be addressed through a formal Change Management Process and agreed with the applicable accreditation authority, as applicable. UKCloud shall not make any changes to technology that it has responsibility for other than those that are known, approved and scheduled, or those considered necessary to complete emergency maintenance or address a serious security incident. The client shall ensure that any changes to their existing applications or data processing arrangements will be subject to the documented requirements of their own approved change management process.  

 

3.4        The protective monitoring of the UKCloud Management Platform environments shall be implemented to identify and manage security incidents. UKCloud shall contact the relevant authorities (e.g. GovCERT, Information Commissioner’s Office) in the event of any such incident as well as invoking the defined Incident Management Process. Clients shall be informed in the event of any such incidents in accordance with the agreed Incident Management Process, and using the client contacts notified within the Security Incident Reporting Matrix (UKC-GEN-56).

 

3.5        The client shall be responsible for complying with all applicable reporting requirements with respect          to their applications and data.  

 

3.6        The client shall promptly inform UKCloud when they detect any Security Incidents in accordance with the Incident Management Process. This shall include proactive notifications of current ongoing security incidents, and reactive notifications for previous security incidents.

 

3.7        UKCloud and the client shall agree with the relevant accreditation and certification bodies the frequency of review of any accreditation or certification status (if applicable).

 

3.8        UKCloud services have been assessed for risk using HMG IS1 and an asset-based risk methodology which supports its ISO27001:2013 certification. Risk assessments shall be reviewed annually to ensure that the risk situation is current and valid. There shall be additional assessments in the event of any major security incident. Any changes to the risk profile shall be informed to the client. The client shall conduct their own IS1/ISO27001 risk assessments and shall review these at least annually, informing UKCloud of any identified changes to their own risk profile.  

 

3.9        UKCloud has responsibility for ensuring that the cloud infrastructure provides the relevant level of security, including protective monitoring (for the UKCloud Management Platform) and Incident Management. UKCloud shall also ensure that all personnel who have access to the infrastructure have obtained and retain the relevant levels of security clearance.

 

3.10      The client shall have responsibility for ensuring that their applications and data are provided with the relevant level of security and that access to those applications and their data is restricted to those who require such access and who have the relevant security clearance.

4.      Asset Management

 

4.1        The UKCloud infrastructure comprises a number of separate environments, each designed for different sectors and employing different security controls. All elements of each environment shall be inventoried and classified to meet the stated requirements of the sector and data classification. All environments shall be assessed for security control effectiveness in relation to data Confidentiality, Integrity and Availability.  

 

4.2        The client shall identify all of their assets to be used within and to access the UKCloud environment and will assess them to ensure their suitability with regards to data Confidentiality, Integrity and Availability.  

 

4.3        UKCloud shall label and handle all management information assets that they have control of        and responsibility for, in accordance with the sensitivity and/or protective marking of each          asset.  

 

4.4        The client shall have sole responsibility for the labelling and handling of their information assets, and any other assets associated with their applications, and for the formal communication of protective marking and/or data classification information to UKCloud. The client shall also be responsible for assessing and complying with their own data aggregation requirements, and for advising UKCloud if this aggregation affects their defined security levels.  

 

4.5        UKCloud shall be responsible for assessing the overall implications of aggregation of data across its cloud infrastructure.

5.      Physical & Environmental Security
