Confidentiality, Integrity and Availability (CIA). Those are all part of information security. This is actually quite interesting, since it is a bit like CAP theorem. When you increase confidentiality and integrity, you might be affecting availability in a negative way. Take Dropbox as an example. Since they don't have efficient end-to-end encryption offering, they can offer you password resets (=availability of data is good). Add in secure end-to-end encryption and password resets won't be enough, you need to have in addition good backups for the encryption keys to ensure access to the data.
