What can have an impact on the availability of information?

The option related to performance degradation is indeed a valid factor affecting the availability of information. Availability is one of the core principles of information security, defined by the ISO/IEC 27001 standard, and it refers to the timely and reliable access to data by authorized users.

Performance degradation can lead to slow response times, increased latency, or even system crashes, which disrupt access to information. For instance, if the network is congested or if server performance deteriorates, users may find it difficult to retrieve the necessary data when they need it. This directly impacts business operations and the ability of employees to perform their tasks effectively, thus compromising the overall availability of information systems.

In contrast, while incorrect results or deliberate changes to information may affect data integrity, and insufficient storage capacity can prevent data from being saved or accessed properly, the specific emphasis on performance degradation directly addresses how system efficiency and reliability can hinder access to data, underscoring its importance in the context of information availability.
