The Saudi Arabia Vision 2030 stated SMEs (Small-Medium Size Enterprises) struggles to access adequate funding from financial institutions. Offer two recommendations specific to how this struggle should be effectively addressed and be in alignment with Saudi Vision 2030.
How many entries would be needed in a “rainbow table” that included all possible salt values and all possible salted hash values?
In the PHP function password_hash , the default algorithm is brcypt which produces a text string derived from a 16-byte “salt” value and a 24-byte salted hash of the supplied password. How many entries would be needed in a “rainbow table” that included all possible salt values and all possible salted hash values? Show your calculations.
State the number of authentication factors used in this scenario, and for each factor state the type of factor and briefly describe the data corresponding to that factor
A well known authentication technology requires users to enter a user ID and 10-digit code to log in. The first 4 digits of the code were chosen by the user when setting up the account, and the last 6 digits are shown on a physical token given to the user by an administrator. State the number of authentication factors used in this scenario, and for each factor state the type of factor and briefly describe the data corresponding to that factor
