A city's online permit portal is taken offline by a volumetric attack the week tax payments are due. Which security pillar is primarily at risk for residents who cannot file?
Select an answer to reveal the explanation.
Short Explanation
When the permit site is knocked offline right before tax day, residents are locked out of a service they need — like a bridge closed during rush hour. The data may still be fine; people just cannot reach it. That is availability under fire.
Full Explanation
Availability ensures authorized users can access systems and data when needed with acceptable reliability. A volumetric denial-of-service attack that takes a permit and tax portal offline during a filing deadline primarily impairs that access. Confidentiality and integrity concerns may arise in other attack patterns, but the scenario centers on service denial for legitimate users.
