Which of the following is NOT a goal of network security?

The goal of network security encompasses various objectives aimed at safeguarding information and systems from unauthorized access and threats. Protecting data integrity ensures that information remains accurate and unaltered during storage or transit. Ensuring confidentiality involves protecting sensitive information from being accessed by unauthorized individuals, thus maintaining privacy. Preventing unauthorized access is crucial as it directly relates to securing networks from attacks and misuse.

In contrast, increasing network bandwidth is not inherently a goal of network security. Bandwidth refers to the amount of data that can be transmitted over a network in a given time frame. While optimizing bandwidth can improve network performance, it does not directly relate to the protective measures taken to secure data and systems. Therefore, the option referring to increasing network bandwidth does not align with the fundamental objectives of network security.
