Lab 1 Part A List of Risks, Threats, and Vulnerabilities

Lab 1 Part B Assessment Questions
1. We chose the ‘User inserts CDs and USB hard drives with personal photos, music, and videos on organization owned computers’ because, the USB device may contain malware allowing unauthorized access to the infected system.
2. User Domain: 2
Workstation Domain: 3
LAN Domain: 5
LAN-to-WAN Domain: 1
WAN Domain: 5
Remote Access Domain: 3
System/Application Domain: 1
3. The LAN and the WAN Domain had the greatest number of risks, threats, and vulnerabilities.
4.
