The Chief Information Security Officer (CISO) is asking for ways to protect against zero-day exploits. The CISO is concerned that an unrecognized threat could compromise corporate data and result in regulatory fines as well as poor corporate publicity. The network is mostly flat, with split staff/guest wireless functionality. Which of the following equipment MUST be deployed to guard against unknown threats?
A. Cloud-based antivirus solution, running as local admin, with push technology for definition updates.
B. Implementation of an offsite data center hosting all company data, as well as deployment of VDI for all client computing needs.
C. Host based heuristic IPS, segregated on a management VLAN, with direct control of the perimeter firewall ACLs.
D. Behavior based IPS with a communication link to a cloud based vulnerability and threat feed.

A university Chief Information Security Officer is analyzing various solutions for a new project involving the upgrade of the network infrastructure within the campus. The campus has several dorms (two-four person rooms) and administrative buildings. The network is currently setup to provide only two network ports in each dorm room and ten network ports per classroom. Only administrative buildings provide 2.4 GHz wireless coverage.
The following three goals must be met after the new implementation:
1. Provide all users (including students in their dorms) connections to the Internet.
2. Provide IT department with the ability to make changes to the network environment to improve performance.
3. Provide high speed connections wherever possible all throughout campus including sporting event areas.
Which of the following risk responses would MOST likely be used to reduce the risk of network outages and financial expenditures while still meeting each of the goals stated above?
A. Avoid any risk of network outages by providing additional wired connections to each user and increasing the number of data ports throughout the campus.
B. Transfer the risk of network outages by hiring a third party to survey, implement and manage a 5.0 GHz wireless network.
C. Accept the risk of possible network outages and implement a WLAN solution to provide complete 5.0 GHz coverage in each building that can be managed centrally on campus.
D. Mitigate the risk of network outages by implementing SOHO WiFi coverage throughout the dorms and upgrading only the administrative buildings to 5.0 GHz coverage using a one for one AP replacement.
