4.5. Summary
Following are key points from this chapter:
Unintentional threats are caused when a user's computer system connects and inadvertently affects the LAN.
Intentional threats are caused when a user knowingly and consciously tries to exploit the LAN.
It is extremely important to understand the actual threats that NAC can address and your company's vulnerabilities before selecting a NAC/NAP solution.
The actual exploits shown in this chapter can be used as ammunition to help justify a NAC/NAP solution.
The biggest threat to the LAN really isn't the outsider's laptop that happens to connect and infect the LAN. That can and does happen, but a user consciously exploiting the LAN is a graver threat.
LAN-based NAC alone will not provide adequate protection; Mobile NAC is also required.
Just as I hope this chapter was eye-opening, Chapter 5 should stop you from sleeping at night (unless you already have a Mobile NAC solution in place).
