What is the most important goal Of CIA in context to Communication??
What is the impact of Integrity and availability on an organization, Military and bank??

I don't think one is more important than the other, but security personnel often forget about the availability when implementing security practices and can often time, through overly zealous, but well-intentioned actions, hinder availability.

For organizations that require near real-time information that is accurate and trusted, Integrity and Availability are key to success, and sometimes means the difference between life and death.
