54 PRT GROUP /SUSTAINABILITY REPORT 2021 1. CONFIDENTIALITY 2. INTEGRITY 3. AVAILABILITY Offering confidentiality means ensuring that data and resources are preserved from possible use or access by unauthorized subjects. Confidentiality must be guaranteed during the whole life of data: from storage to use or transit along the connection network. Integrity is the ability to maintain the truthfulness of data and resources, and guarantee that they are not modified nor canceled, except by authorized subjects. Availability refers to the possibility for authorized subjects to access the resources they need for a fixed time and in a continuous way. This allows to prevent service interruptions and ensures that infrastructures are ready to provide resources in a correct way when requested.
