Tipos de amenazas en los Sistemas Informáticos

Podemos agrupar en cuatro tipos generales las amenazas o ataques a los sistemas informáticos:

  1. Ataque de interrupción: Este se considera un ataque a la disponibilidad. Un recurso del sistema es destruido o deja de estar disponible.
  2. Ataque de intercepción: Este es un ataque contra la confidencialidad. Una entidad no autorizada consigue acceso a un recurso, un ejemplo es laescucha de una línea para interceptar la información privada que fluye por la misma.
  3. Ataque de modificación: Es un ataque contra la integridad. Una entidad no autorizada no solo consigue acceder a un recurso, sino que es capaz de modificarlo.
  4. Ataque de fabricación: Se produce cuando una entidad no autorizada inserta objetos falsificados en el sistema. Se considera un ataque contra el ‘no repudio‘.
