  • 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
slide6
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
