Annualized Rate ntawm qhov tshwm sim (Kev txhais)

Qhov tshwm sim uas qhov kev pheej hmoo yuav tshwm sim hauv ib xyoos twg. Piv txwv li, yog tias cov ntaub ntawv pov hwm pom zoo tias hluav taws kub hnyav yuav tshwm sim ib zaug hauv 25 xyoo, ces qhov txhua xyoo tus nqi luas = 1/25 = 0.04. Saib Ntxiv: Txhua xyoo Loss Expectancy.

Tsuas yog li ntawd, koj yuav ua li cas xam tus nqi txhua xyoo ntawm qhov tshwm sim?

Txhua xyoo tus nqi ntawm qhov tshwm sim (ARO) tau piav raws li qhov kwv yees qhov zaus ntawm kev hem thawj tshwm sim hauv ib xyoos. ARO yog siv rau xam ALE ( ib xyoos ib zaug poob expectancy). ALE yog xam raws li nram no: ALE = SLE x ARO. ALE yog $15,000 ($30,000 x 0.5), thaum ARO kwv yees li 0.5 (ib zaug hauv ob xyoos).

Ib yam li ntawd, ob qhov txiaj ntsig dab tsi yuav tsum suav nrog kev poob txhua xyoo? Hauv xam txaus ntshai, muaj ob Cov qauv siv dav dav uas siv: SLE (ib leeg poob expectancy ) thiab ALE ( txhua xyoo poob expectancy ). SLE yog qhov pib los txiav txim siab ib leeg poob uas yuav tshwm sim yog hais tias ib yam khoom tshwm sim. Cov mis rau SLE yog: SLE = khoom vaj khoom tsev tus nqi × exposure factor.

Tsis tas li ntawd nug, yuav ua li cas poob kev cia siab ib xyoos twg?

Txhua xyoo Loss Expectancy (ALE) = Ib Loss Expectancy (SLE) X Txhua xyoo Tus nqi tshwm sim (ARO) Txhua xyoo Rate of Occurrence (ARO) yog tus lej uas sawv cev rau kwv yees zaus uas yuav tsum muaj kev hem thawj tshwm sim. Ib leeg Loss Expectancy (SLE) yog tus nqi hauv cov nyiaj uas tau muab rau ib qho kev tshwm sim.

ale xam yog dab tsi?

Lub xyoo poob expectancy ( ALE ) yog xam raws li cov khoom ntawm cov cuab tam tus nqi (AV) lub sij hawm qhov tshwm sim tshwm sim (EF) lub sij hawm tus nqi txhua xyoo ntawm qhov tshwm sim (ARO). Qhov no yog daim ntawv ntev ntawm lub formula ALE = SLE x ARO.
