Question
There are two separate networks in the Action Forensics’ facility. The first network, shown here, is the administrative network used by the president, secretary, and network technician. Each device or computer has its own UPS for power backup.
The second network, shown here, is the forensic network used by the eight forensic investigators, evidence custodian, and the network technician. Each device or computer has its own UPS for power backup. The only information allowed on the dedicated Internet connection is backup data from the SAN to the offsite data backup facility.
Every computer on both networks runs Windows 7. The eight forensic workstation computers are all dual boot and run Ubuntu Linux as well. All Windows systems have the current version of Microsoft Office.
Only the network technician has administrator rights on all computers on both networks.
Use the information provided here, both from the description and the two network diagrams, to fill in the spreadsheet to your best ability.
This question asks that the above spreedsheet be filled out. Code and/or a written paragraph is not needed or wanted for this answer. Thank you.
