Sikkerhetsmomenter

Sikkerhetsmomenter

  • Konfidensialitet

  • Integritet

  • Tilgjengelighet

  • Autentisering

  • Non-Repudiation (Uomtvistelig)

  • Sporbarhet


Ord og definisjoner

Ord og definisjoner

  • Risiko

  • Trussel

  • Sårbarhet

  • Tiltak (Sikring, Sikkerhetstiltak)

  • Eiendeler

  • Verdier

  • Beskyttelseskrav


Termer og definisjoner

Termer og definisjoner

  • Trussel: kilde eller situasjon som potensielt kan påføre organisasjonens eiendeler skade

  • Risiko: Sjansen for at noe skjer som kan ha påvirkning på ulike objekter, målt i sannsynlighet og konsekvens

  • Akseptabel risiko: Risiko redusert til et nivå som kan aksepteres av organisasjonen

Sikkerhetsmomenter

  • Exposure, likelihood (L) is specified from 1 to 3 where 1 is low (<30%), 2 is middle (30 –70%) and 3 is high (>70%)

    • Eksponering

  • Consequence (C) is specified when possible from 1 to 3 where 1 is low (of minor sighnificance), 2 is medium (impacts the result), and 3 is high (goal not achievable)

    • Konsekvens

  • Level of Threat ( T ) is Likelihood (L) ”multiplied” by Consequence (C).

    • Trusselnivå

  • Control Measures (M) specifies to which degree the measures described are considered effective. Low – Medium – High.

    • Kontrollmuligheter

  • The column for Risk Level (R) specifies the evaluation result as Low – Medium – High based on the scheme for Risk Assessment

    • Risikonivå
