We have set out how our organisation classifies the information we process, and how users should handle that information, in section 1 of our Information Security Policy. The Information Security Policy is the primary policy we use to communicate our requirements for the secure use of devices, workspaces, and information to all users of our information systems and assets. However, when data is first collected or created, it may not be immediately clear how the data should be classified, or who the owner of the data may be. This may result in information being inadvertently shared, or even deleted where it should be retained, which is of particular concern when processing personal data.
To minimise the risk of inappropriate collection or sharing, accidental loss or destruction, or unauthorised access in these types of scenarios, our organisation has set out best practice principles to help guide our users in the protection of information throughout its lifecycle.
This document applies to all information that we process as part of our work-related activities. Where there is overlap between the data classification and handling requirements set out in the Information Security Policy and this document, the Information Security Policy shall take precedence.
All employees, contractors, and other relevant third-parties shall understand and follow this document when determining how data should be collected, handled, and retained. For the purposes of this document, instructions directed at employees shall also apply to contractors, and other relevant third-parties, and shall be collectively referred to as “users”. Where discussing the classification and handling of information, users with overall responsibility for the data shall be referred to as the “data owner”.
These Data Handling & Retention Guidelines shall be communicated to all employees and agency staff as part of our employee induction programme, and periodically following any changes to the available guidance and compliance requirements. All contractors and other relevant third-parties shall be provided with a copy of this document as part of the process for contracting services, and shall be re-issued with updated versions periodically following any changes to the guidelines.
It is understood that this document and the guidance set out in it may not cover every scenario that arises, or be applicable to every type of data that we handle. However, employees, contractors, or other relevant third-parties performing activities which clearly disregard the guidelines set out in this document shall be subject to the disciplinary process documented in the Company Manual, or the applicable service contract.
Management are committed to the continual improvement of our Data Handling & Retention Guidelines, and shall review this document on an annual basis, or whenever an independent review reveals a change in legal and/or regulatory requirements. The Management Review shall determine if this policy continues to meet the requirements of our organisation.
Management also endeavours to plan our business operations so that our information is not misused, either intentionally or unintentionally. This is done by identifying and assigning separate duties throughout our critical business activities to guard against misuses such as illegal transfers, or other errors in data processing activities, etc. Where a user identifies potential conflicts or misuse of information due to improper planning and assignment of duties, users should raise their concern immediately with their line manager, or the ISMS Manager.
To ensure that the data we process is handled and protected appropriately, it is important for all users and data owners to know and understand best practice principles for data processing. Our organisation uses the data privacy principles set out in the General Data Protection Regulation (GDPR) as the core principles for the handling of all information we process, regardless of data type or classification. This section sets out these core principles, and how our organisation expects users and data owners to adhere to them in their day-to-day activities.
1.1 Limit Use of the Data
This principle is frequently referred to as “purpose limitation”. Information is usually collected for a purpose, and understanding that purpose will assist in identifying the correct controls for handling and retaining it, such as who should have access to it, where it should be stored, how long it should be kept for, etc. Where information is taken and used for a different purpose than what it was collected for, users could expose the data to risks such as unauthorised access, misuse, or non-compliance with legal or regulatory considerations.
For personal data, the data can only be used for a different purpose when permitted by law. For example, where customer contact data has been collected for the purpose of providing product support, it would not be compatible or lawful for that contact data to be used in a digital marketing campaign unless the customer provided their explicit consent to do so.
Users and data owners should always consult with the ISMS Manager and/or Data Protection Lead when considering using data for a purpose other than what it was originally collected for.
1.2 Have a Genuine Reason
Processing information when there is no defined business case for it can expose our organisation to unnecessary data breaches, or legal and regulatory penalties. Where information is collected simply because it seems like it may be useful at the time, it may result in a lack of defined controls or ownership of the data, and an increased level of risk due to inappropriate storage and/or protection.
For personal data, processing without an appropriate legal basis is unlawful. For example, an employer would have no legal basis for sharing employee data with a private research organisation studying workforce demographics, even though the data would be legitimately interesting to the private research organisation, and the employer may receive payment for sharing the data. This is because employees would likely have no knowledge of the private research organisation’s activities, and the employer would have no lawful reason to share the employee data for the purposes of private research. The employees’ information could only be processed lawfully by the private research organisation where the organisation has received explicit consent directly from the employees, or where the employer sufficiently anonymises the data so that it is no longer considered personal data.
The GDPR currently sets out the following legal bases for the processing of personal data:
In addition to the above, there are situations in which lawful processing may take place on the following bases:
When initiating and developing projects that involve the collection of information, data owners should always consult with the ISMS Manager and/or Data Protection Lead to ensure there is a valid legal basis or business case for processing the information.
1.3 Use Data Fairly
Even where information has been collected and processed for a genuine reason, the processing activity may produce unfair results, or unfairly or negatively impact individuals. This could expose our organisation to potential reputational damage, or loss of trust, and being legally correct in this instance may not be beneficial.
Data owners should always consider the needs and expectations of all interested parties when considering how to use information. In particular, when working on projects that involve the collection and processing of personal data, data owners shall always ensure that:
1.4 Be Open & Honest
Unless required to maintain strict confidentiality for certain information processing activities, transparency about why and how we use information creates trust and confidence in our colleagues, customers, business partners, employees, suppliers, and other interested parties. A data owner or user who is not open and honest about what data they are collecting and how they are using it may expose the organisation to unnecessary data breach, legal and regulatory penalties, or even cause harm to individuals. Whether being honest about the applications used, where data is stored, or who it is shared with, data owners and users should ensure they clearly communicate this information to line managers and/or relevant team members so that the data can be appropriately handled and protected.
For personal data, individuals have the legal right to be informed about the use of their personal data. Data owners shall consult with the Data Protection Lead to ensure that information about the use of personal data is clearly and appropriately communicated to individuals in line with applicable data protection law.
1.5 Only Use What’s Necessary
This principle is known as “data minimisation”, and supports the principle of data protection by design and by default. Where we don’t absolutely need the data to carry out a required task or meet a business objective, then we shouldn’t collect it, as limiting what we process automatically minimises our organisation’s exposure to data breach, misuse of data, and legal and regulatory penalties. Quite simply, if we don’t have it, then we can’t lose or expose it.
For personal data, our organisation is legally obligated to collect only what is absolutely necessary to achieve the objective of the processing activity. For example, where a web-service provider needs only a verified email address and username to authorise a user’s access to their application, it would be unnecessary to ask a user for information about their gender, location, address, or age for the purposes of authenticating their account. The additional identity data would not only be irrelevant, with no genuine reason to collect and retain it, but in the event of a data breach, a malicious attacker would have a lot more information about users. This information could then allow a malicious attacker to more effectively target a user for scams, fraud, or possible identity theft.
When initiating and developing projects that involve the collection and processing of data, data owners should ensure they only collect and use what they need.
1.6 Keep Data Accurate
Whether using data for research and analysis, or maintaining customer or employee records, data that is inaccurate or out of date can negatively impact business decisions and operational activities, as well as our employees, customers, suppliers, and other interested parties. In the case of personal data, individuals have a legal right to expect their personal information to be kept accurate and available. This means that data owners should identify and document appropriate procedures for maintaining the accuracy and integrity of the information used, and ensure they are clearly communicated to users who may work with the data. Users should ensure they adhere to the procedures, and appropriately maintain the accuracy of the information they work with.
1.7 Don’t Store Data Longer Than Necessary
From having to convert data into formats suitable for archiving, to maintaining legacy equipment to be able to retrieve the information, storing data for long periods of time can not only introduce business costs and operational difficulties, but where data is kept for longer than necessary, it also exposes our organisation to increased risk of data breaches, and legal and regulatory penalties. For personal data, our organisation is legally obligated to securely dispose of the data once it has fulfilled its purpose.
Using the legal, regulatory, and contractual considerations identified in section 1 of the Information Security Policy and our Critical Asset Register, data owners shall identify appropriate retention periods for the data we process, record these periods to section 2 of this document for reference, and ensure appropriate procedures are implemented to delete information when retention periods are met. Where necessary, data owners should also document and communicate data removal procedures to users who may work with the data to ensure continuous compliance with retention requirements.
1.8 Keep Data Safe & Secure
Regardless of whether the information we collect or create has been classified or assigned a data owner, ensuring that it is protected by default will minimise the risk of unauthorised and potentially illegal access, loss, corruption, reproduction, illegal transfer, or destruction. As mentioned earlier in these guidelines, our Information Security Policy is the primary policy we use to communicate our requirements for the secure use of devices, workspaces, and information to all users of our information systems and assets. Data owners and users shall adhere to our Information Security Policy, and treat all information as confidential unless specifically labelled otherwise. This will ensure there is always a minimum level of protection applied to the information we process.
1.8.1 Technically masking data
In addition to the requirements for proper handling and use of information and information assets as set out in our Information Security Policy, our organisation may be obligated to comply with contractual, legal, or regulatory requirements to technically restrict access to data by using approved techniques to mask it. It may also be necessary to mask data due to the level of risk associated with the inappropriate use or access of the information. Some technical mechanisms that can be used to mask data may include, but are not limited to:
Data owners shall use the legal and regulatory considerations identified in section 1 of the Information Security Policy and the Critical Asset Register to identify any requirements to mask data, and work with administrators to ensure appropriate masking techniques are identified and implemented, taking into consideration the policies for access control, network protection, and cryptographic controls set out in the Information Systems Security Policy.
1.8.2 Preventing data leakage
Even where data owners and users adhere to the requirements set out in our Information Security Policy, the daily use, copying, sharing, and transmission of data may result in unintended loss, leakage, or even malicious exfiltration. Where working with sensitive information, it may be necessary to implement additional technical mechanisms to prevent unintended copying and sharing of information. Some technical mechanisms may include, but are not limited to:
Data owners shall determine the risks associated with the loss of the sensitive information, and work with administrators to ensure suitable mechanisms for preventing data leakage are identified and implemented, where appropriate.
1.9 Keep Track of Data
Necessary security controls and retention procedures cannot be applied to data that is not appropriately identified and tracked. For personal data, this is referred to as the principle of “accountability”, and depending on the size of the organisation and nature of the processing activities, may require the creation and maintenance of records of processing. Failure to keep track of the information we handle may expose our organisation to increased risk of data breaches, and legal and regulatory penalties.
Our organisation keeps track of the information that we handle by identifying, recording, and managing our information assets in line with our ISO 27001-aligned information security management system (ISMS), as documented in our ISMS Manual. The legal and regulatory requirements applicable to these information assets are recorded to our Critical Asset Register, and also used to maintain the legal and regulatory considerations documented in section 1 of our Information Security Policy. Data owners shall ensure the necessary retention periods set out in these legal and regulatory requirements are identified and recorded to section 2 of this document.
Where changes to existing information assets occur, or where new information assets are identified, data owners shall review and update the below section, as appropriate.
As mentioned in section 1.7 above, data that we collect and use must only be retained as long as necessary. Data retention requirements may be set out in laws and regulations, determined by our customers in contracts, or even set by data owners based on our organisation’s own business requirements.
Data owners shall use the applicable laws, regulations, contracts, and other considerations identified in our Critical Asset Register, and section 1 of our Information Security Policy, to identify expected retention periods for the information we process, and document these in the table below.
