This Control states that the rules for the acceptable use and procedures for handling information and other associated assets should be identified, documented and implemented. There must be a clear guidelines of how users should behave when working with information assets, to ensure confidentiality, integrity and availability of the organisation’s information security assets.Acceptable use of information and other associated assets means using information assets in ways that do not put at risk the availability, reliability, or integrity of data, services or resources. It also means using them in ways that do not violate laws or the organisation’s policies The Acceptable Use of Information Assets applies to all members of an organisation and assets owned or operated by the organisation. It applies to all uses of Information Assets for any purpose, including commercial. The following are examples of Information Assets:
- Hardware: computers, mobile devices, phones and fax machines.
- Software: operating systems, applications (including Web-based apps), utilities, firmware and programming languages.
- Data: structured data in relational databases, flat files and No SQL data; unstructured data such as text documents, spreadsheets, images, video and audio files; records in any format.
- Networks: wired and wireless networks; telecommunications systems; voice over IP services.
- Services: cloud services, email accounts and other hosted services.
Rules for the acceptable use and procedures for handling information and other associated assets should be identified, documented and implemented.
To ensure information and other associated assets are appropriately protected, used and handled.
ISO 27002 Implementation Guidance
Personnel and external party users using or having access to the organization’s information and other associated assets should be made aware of the information security requirements for protecting and handling the organization’s information and other associated assets. They should be responsible for their use of any information processing facilities.
The organization should establish a topic-specific policy on the acceptable use of information and other associated assets and communicate it to anyone who uses or handles information and other associated assets. The topic-specific policy on acceptable use should provide clear direction on how individuals are expected to use information and other associated assets. The topic-specific policy should state:
- expected and unacceptable behaviors of individuals from an information security perspective;
- permitted and prohibited use of information and other associated assets;
- monitoring activities being performed by the organization.
Acceptable use procedures should be drawn up for the full information life cycle in accordance with its classification and determined risks. The following items should be considered:
- access restrictions supporting the protection requirements for each level of classification;
- maintenance of a record of the authorized users of information and other associated assets;c) protection of temporary or permanent copies of information to a level consistent with the protection of the original information;
- storage of assets associated with information in accordance with manufacturers’ specifications;
- clear marking of all copies of storage media (electronic or physical) for the attention of the authorized recipient ;
- authorization of disposal of information and other associated assets and supported deletion method.
It can be the case that the assets concerned do not directly belong to the organization, such as public cloud services. The use of such third-party assets and any assets of the organization associated with such external assets (e.g. information, software) should be identified as applicable and controlled, for example, through agreements with cloud service providers. Care should also be taken when a collaborative working environment is used.
After going through the asset inventory, categorization, and ownership identification, ensure there are documented policies regarding the acceptable use of assets. Define, and document, the rules that clarify the acceptable uses of assets associated with information and information processing facilities. It is important, once the rules are clarified, that appropriate controls are implemented and the security requirements are communicated. Target the communication of security requirements to employees and, if appropriate, third parties who may use these assets. Accountability is key. Asset owners should be responsible and accountable, even if the owner has delegated responsibility, for their use of facilities and resources. The Control was designed to ensure that policies, procedures and technical controls are in place to prevent users from inappropriately accessing, using or disclosing information assets.This control aims to provide a framework for organisations to ensure that information and other assets are appropriately protected, used and handled. This includes ensuring that the policies and procedures exist at all levels within the organisation, as well as ensuring that those policies and procedures are consistently enforced. You have put in place the various requirements related to how your company protects IT assets including:
- The protection of information in storage, processing and transit.
- The protection and appropriate use of IT equipment.
- The use of appropriate authentication services to control access to information systems.
- The processing of information within an organisation only by users with appropriate authorisation.
- The allocation of information-related responsibilities to specific individuals or roles.
- The education and training of users regarding their security responsibilities.
You will need to develop procedures for handling assets associated with your information and information processing facilities. It is important that your asset handling procedures respect and reflect how you classified it. Ensure that
- Information is handled and protected according to its classification. This includes sharing with external entities.
- There are procedures to control classified information. Clarify how yours, and perhaps others’, classifications should be interpreted.
- Information is stored, processed, transmitted and copied according to its classification. Copies should get the same protections.
- Access restrictions are designed for each level of classification. Restrictions must meet protection requirements.
- There is a formal record of the authorized recipients of the assets. Specify who the authorized recipient should be. Label media copies appropriately.
All of the above bullet points can be incorporated into one procedural access handling document. Remember, keep it simple so others will be able to understand and comply with the requirements. Hold a session with your information and physical asset owners so they can help you define the requirements. It’s important everyone feels ownership of this process.
