How long must the Log of Dissemination of Information be kept for?

The correct duration for retaining the Log of Dissemination of Information is one year. This timeframe is significant because it aligns with records management policies and legal requirements that dictate how long certain types of information must be kept for accountability and auditing purposes. Retaining the log for one year ensures that there is an appropriate period for reviewing and analyzing the data if needed, while also allowing for the disposal of older records to manage data retention effectively.

In contrast, the other options suggest either excessively short or undefined periods for record retention, which would not be practical for maintaining comprehensive oversight of disseminated information and could hinder investigative processes if historical data were unavailable.
