Sissejuhatus

So what's the answer? Paranoia and knowledge. First, never put too much faith in the tech. It's not enough, for example, for encryption to be an option -- you want encryption enforced so that unencrypted is not an option. Second, learn how things work. Learn why SSL works the way it does, why it's POP3S and not POP3, and why "certificate warnings" are a thing. The more important security is to you, the more conservative your paranoia and the more extensive your knowledge should become.

Infoturve

Infoturve tegeleb andmete ja infosüsteemide kaitsmisega. Infoturve abil luuakse reeglid nende kasutamiseks, juurdepääsuks ja modifitseerimiseks. Infoturbes on kesksel kohal järgnevad mõisted: käideldavus, konfidentsiaalsus, terviklikkus. Infoturve peab tagama andmete käideldavuse, konfidentsiaalsuse ja terviklikkuse.

Käideldavus (Availability) - “Andmete käideldavus on eelnevalt kokkulepitud vajalikul/nõutaval tööajal kasutamiskõlblike andmete õigeaegne ja hõlbus kättesaadavus (st vajalikul/nõutaval ajahetkel ja vajaliku/nõutava aja jooksul) selleks volitatud tarbijaile (isikutele või tehnilistele vahenditele).” https://www.ria.ee/iske-kkk/

Konfidentsiaalsus (Confidentiality) - info ja andmete omadus, mis takistab kolmandatel osapoolte juurdepääsu. Juurdepääs andmetele või infole on ainult volitatud inimestel.

Terviklikkus (Integrity) - omadus, mis tagab selle, et andmed on õiged, täielikud ja autentsed.
