Problem
The LAN-to-WAN Domain is where the IT infrastructure links to a wide area network (WAN) and the Internet. A WAN is a network that covers a large area, often connecting multiple LANs. The LAN-to-WAN Domain includes the physical pieces and logical design of security appliances, for example.
The WAN Domain connects remote locations. It includes the equipment and activities outside of the LAN and beyond the LAN-to-WAN Domain.
Discuss the following questions:
1) What types of vulnerabilities affect the LAN-to-WAN Domain?
2) What types of vulnerabilities affect the WAN Domain?
3) Which of the two domains, LAN-to-WAN or WAN, is more at risk in terms of vulnerability?
4) What are common methods for managing vulnerabilities?
