Describe a modification to the random port scan, as described in the previous exercise, so that it still uses a randomly generated sequence of port numbers but will now have exactly the same number of attempted TCP connections as a sequential port scan

What will be an ideal response?


The modification needed for the random port scan is to perform a sequence of
port scans that forms a random permutation of the numbers from 1 to 65535. This can be
done, for example, by having the random port scanner store the port numbers of ports it
has already probed and then not reissue TCP connection attempts for those ports.
