Now that we ’ ve covered all the topics of the CCNA Security
exam, it ’ s time to do one fi nal practice exercise. This exercise
will cover many of the topics of the previous chapters, but they
will be part of what could be considered a real - world scenario. In this scenario, a corporation
with headquarters in Chicago is connected to a remote offi ce located in San Francisco.
The remote offi ce also has an Internet connection, rather than going back to headquarters
for this service. The San Francisco remote offi ce also has a business partner in Oakland
that will come into play later in the exercise.
Many of the topics that we have studied will be applicable to this exercise:
■ Layer 2 security
■ IOS firewall
■ IOS intrusion prevention system (IPS)
■ Authentication, authorization, and accounting (AAA)
■ Securing the router
■ Virtual private networks (VPNs)
Let ’ s take a look at the network diagram that we will be working with in this exercise,
