Which principle is NOT a component of Information Assurance?

Transaction speed is not a component of Information Assurance because the primary focus of Information Assurance is to protect and manage information systems by ensuring the confidentiality, integrity, availability, authenticity, and non-repudiation of data. While transaction speed can be an important factor in system performance, it does not align with the core principles that address security and protection of information.

On the other hand, non-repudiation ensures that a sender cannot deny having sent a message and that a recipient cannot deny having received it, thus protecting the authenticity of transactions. Integrity involves maintaining the accuracy and completeness of data, ensuring it is not altered in unauthorized ways. Confidentiality is about keeping sensitive information secret from unauthorized access, ensuring that only those who are authorized to see the information can access it. These principles are all integral to establishing a secure information environment, making transaction speed an irrelevant concern within the framework of Information Assurance.
