Annex A 5.12 - Classification of Information
Description
Title of Control: Classification of Information
Introduction (what is it?): This control emphasizes the importance of classifying information based on its security needs. The classification takes into account factors such as confidentiality, integrity, availability, and the requirements of relevant interested parties. The purpose is to identify the protection needs of information and ensure that appropriate safeguards are applied according to its importance to the organization.
What is the purpose of it? The purpose of this control is to ensure that information is categorized and classified according to its security requirements. By classifying information based on its sensitivity and importance, organizations can effectively allocate protective measures and controls to safeguard the confidentiality, integrity, and availability of their data.
What are the benefits of meeting these requirements? Meeting these requirements offers several benefits:
Effective Protection: By classifying information, the organization can tailor protective measures to match the sensitivity of the data, ensuring that valuable assets are adequately safeguarded.
Risk Management: Classification helps identify the appropriate level of protection needed for each type of information, aiding in risk assessment and management.
Efficient Handling: Classification guides personnel in handling and protecting information consistently and appropriately, reducing the need for case-by-case decisions.
Compliance: Classification assists in aligning protective measures with legal and regulatory requirements related to information confidentiality, integrity, and availability.
How difficult is this control to meet? Establishing an information classification scheme is of moderate difficulty. It requires coordination between various stakeholders to define the classification levels, naming conventions, and criteria. However, once established, maintaining and applying the classification scheme becomes a standard practice.
What are the sub-requirements?
Establish a topic-specific policy on information classification and communicate it to relevant parties.
Develop a classification scheme that considers confidentiality, integrity, availability, and business needs.
Assign accountability for the classification of information to information owners.
Define conventions for classification and criteria for reviewing and updating classifications over time.
Align the classification scheme with the access control policy (5.1) and incorporate it into organization procedures.
Ensure consistency of the classification scheme across the organization and interpret classifications from external sources.
Customize the classification scheme to address the specific business needs of the organization.
Other information:
Information classification assists in determining the appropriate level of protection and control measures for each category of data.
Classification might be based on levels that indicate the impact of information compromise on the organization, such as minor or significant operational impacts.
The classification scheme can evolve over time to accommodate changes in the value, sensitivity, and criticality of information.
Over-classification can lead to unnecessary controls and expenses, while under-classification can result in inadequate protection.
In conclusion, the classification of information is essential for allocating appropriate protective measures and controls to safeguard organizational assets. By categorizing information based on confidentiality, integrity, availability, and relevant requirements, organizations can efficiently manage risks, comply with regulations, and ensure the consistent and appropriate handling of their data.
