After this weeks readings and your own research, describe and discuss ways, if any, we can safely share security data.Are there precautions we can take, technical solutions we can use, e.g., like using the CIA triad, or should we just not share these kinds of data? Feel free to argue for and against, just make sure to back up your statements with scholarly support.
Please make your initial post at least 500 to 600 words. Please add APA 7 format and intext citations and mention all the references used in the paper with indent hanging format.
At least one scholarly source should be used in the initial discussion thread. Be sure to use information from your readings and other sources from the UC Library. Use proper citations and references in your post.
