a) The first option is correct because the intruder can use denial-of-service attack and by flooding the site with traffic to get the voter server unavailable. Then he can direct the voters to a fraud vote server.
b) The second options correctly applies too because the thief also buys the pass codes from the people who want to sell their right to vote and this way the thief can purchase multiple pass code and cast multiple votes.
c) The hackers can set up fake vote servers and then direct the voters to these servers or websites in order to collect pass codes of voters. These pass codes can then be misused by the thief to cast multiple votes in an online election.
d) Social engineering techniques can also be used to get pass codes from certain voters. By manipulating the targeted voters psychologically they can get their pass codes to cast multiple votes illegally.
A flag is a piece of fabric (most often rectangular or quadrilateral) with a distinctive design and colours. It is used as a symbol, a signalling device, or for decoration.8086 has 16-bit flag register, and there are 9 valid flag bits.The FLAGS register is the status register in Intel x86 microprocessors that contains the current state of the processor. This register is 16 bits wide. Its successors, the EFLAGS and RFLAGS registers, are 32 bits and 64 bits wide, respectively. The wider registers retain compatibility with their smaller predecessors.
