  • Formula for calculating RTO; using turnover

    I am not new in this world of standrads, but have difficulty explaining to people how they should calculate their acceptable losses (due to RTO). People waiting to get some kind of formula, though I believe that such a formula does not exist. I'm trying to relate it to turnover (percentage of it) but I´m not sure what is the best practice in that, which percentage is usually preferred. I know that there are many other dependencies too.
  • Information Security Risk Assessment

    Hello there i am in the process of performing risk assessment for all departments of the company.  i followed that approach for identification and evaluation of the asset value: 1- interviewed each head of department. identified information assets (started with electronic data). for each information asset (electronic data) - for example customer information, payroll information, etc. identified the asset containers (where such assets are stored (for example - Navision application, MS-sql database, user's PC, company file servers, backup tapes, etc.).  2- Interviewed each head of department in relation to information asset value (which is based to a predefined BIA matrix). for example what could be the impact in case the confidentiality of the information asset is compromise. i used values low - moderate - high. and i repeated that for each asset. 3- based to that information i put the value of information asset containers to max of the asset values that store (for example if NAVISION has customer information (moderate) and payroll information (high) - then i put the value of confidentiality for NAVISION to high. 4- during interviews I identified around 50 information assets (electronic data) and i mapped them to 5 information assets (navision and its related infrastructure (ms-sql and windows), file server, User PCs and backup tapes). all of them were rating as high (using the above mentioned logic). 5- after that i identified threats/vulnerabiltiies for each of these 5 assets. 6- i calculated risks using formula = propability * impact (which is evaluated in point 3). please let me know if this correct.. or i am missing something. thanks
