During a storm, the city's 911 CAD system goes down even though no records were stolen. Which CIA objective was primarily violated?
Select an answer to reveal the explanation.
Short Explanation
If the fire truck radio works but the dispatch screen is dark, you have an availability problem — people who should use the system cannot. No leak required. CIA is three separate dials, not one blob.
Full Explanation
Availability ensures authorized users can access systems and data when needed with acceptable reliability. An outage of computer-aided dispatch during a storm is an availability failure even when confidentiality and integrity are intact. Security+ candidates must recognize that CIA violations can occur independently; a breach is not required for an availability impact. Non-repudiation is a related but distinct concept about denying authorship of actions.
