Imagine you are an Information Systems Security Officer for a medium-sized financial services firm that has operations in four (4) states (Virginia, Florida, Arizona, and California). Due to the highly sensitive data created, stored, and transported by your organization, the CIO is concerned with implementing proper security controls for the LAN-to-WAN domain. Specifically, the CIO is concerned with the following areas:
Protecting data privacy across the WAN
Filtering undesirable network traffic from the Internet
Filtering the traffic to the Internet that does not adhere to the organizational acceptable use policy (AUP) for the Web
Having a zone that allows access for anonymous users but aggressively controls information exchange with internal resources
Having an area designed to trap attackers in order to monitor attacker activities
Allowing a means to monitor network traffic in real time as a means to identify and block unusual activity
Hiding internal IP addresses
Allowing operating system and application patch management
The CIO has tasked you with proposing a series of hardware and software controls designed to provide security for the LAN-to-WAN domain. The CIO anticipates receiving both a written report and diagram(s) to support your recommendations.
