Adatintegritás

Az informatikában és a telekommunikációban, az adatintegritás kifejezés a következőket jelenti:

  1. Annak a feltételnek a megléte, hogy az adat helyes, és semmiféle művelet, mint például adatátvitel, tárolás, visszaállítás nem károsította meg az eredeti adatot.
  2. Az adat helyesen áll rendelkezésre a kezelés számára.
  3. Meghatározott műveletek szempontjából alapvető adat minőségi elvárás.

Más szempontok alapján az adat integritás biztosíték arra nézve, hogy az adathoz csak felhatalmazott, jogosult fér hozzá, vagy módosíthatja.

A kriptográfiánál és az informatikai biztonságnál az integritás az adat megbízhatóságára vonatkozik. Az integritás valójában azt jelenti, hogy az adat nem módosulhat két ok miatt:

  • Rosszindulat miatti módosulás:
    • Támadó általi
    • Helytelen kezelés miatt
  • Üzemzavar miatti módosulás:

A relációs adatbázisok esetében az adat integritás azt jelenti, hogy az adatbázis (és a benne tárolt adatok) megfelelőek a következő három szempont alapján:

  1. Naprakészség
  2. Megbízhatóság
  3. Érvényesség
