Consider a system that uses a 32-bit unique salt where users have a 4-digit number as a password (e.g. 6813). Eve wants to crack

Alenkasestr [34]

Answer:

18000 seconds or 300 minutes.

Explanation:

In the example given in the question, it is stated that the system uses 32-bit unique salt which is equal to 4 bytes where every digit takes up 1 byte thus forming the 4 digit passwords.

Considering that the passwords are 4 digits, starting from 1000 and up to 9999, there are 9000 possible password combinations.

If Eve has to go through the whole range of possible password combinations and it takes her 1 second to guess 1 password. Then in the worst case scenario, it would take her 18000 seconds or 300 minutes to crack both accounts, assuming that it is possible for them to use the same passwords.

I hope this answer helps.

Ensure that the hardware are compatible to IPv6 and/or IPv4 and adjust the settings of the network as required

5) Other IP related IP issue

An IP issue can lead to not being able to successfully connect to a network which can be resolved releasing the IP and flushing the DNS cache.
