As a matter of fact, Beatrice (as a man in the middle) passively eavesdrops on all the documents being sent by users to the printer. Describe a data structure for keeping track of all open TCP connections for a machine. The data structure should support e_ciently adding and deleting connections and searching by host, source port, and destination port. For the data structure, one needs to create a record for each connection of available TCP (transmission control protocol) connection and store all records in a double linked list Q. the double linked list ought to support insertions and deletions within constant time; assuming that a link to the record to be deleted/inserted is provided. In order to search competently for a TCP connection record by either using host or source port or destination port, create three search structures such as red-black trees or hash tables that store items of the type (x; y), in which x is the search key and y is a link to a connection record in Q. An intruder can get an upper hand by stealthily watching legitimate users for a week because by doing so he can determine what is normal and or accepted behaviors for each user (Shannon, p. 25-32). Consequently, he can try to mimic or imitate the noted behaviors of which minimize the probability of raising any intrusion alarms when he attacks the victim computer.

Describe a modi_cation to the random port scan, as described in the previous
