Availability ensures that authorized users can access the required information at all times. It includes measures to ensure business continuity and minimize downtime so that important data and services are always available. This is achieved through disaster recovery plans, redundant systems and regular availability testing.
ISO 27001 and BSI Grundschutz emphasize availability as crucial for maintaining business processes. Both standards recommend the implementation of emergency plans and regular checks of system availability to ensure that authorized users can access the information they need at all times. This contributes to the stability and reliability of the IT infrastructure.
