A small retail company recently deployed a new point of sale (POS) system to all 67 stores. The core of the POS is an extranet site, accessible only from retail stores and the corporate office over a split-tunnel VPN. An additional split-tunnel VPN provides bi-directional connectivity back to the main office, which provides voice connectivity for store VoIP phones. Each store offers guest wireless functionality, as well as employee wireless. Only the staff wireless network has access to the POS VPN. Recently, stores are reporting poor response times when accessing the POS application from store computers as well as degraded voice quality when making phone calls. Upon investigation, it is determined that three store PCs are hosting malware, which is generating excessive network traffic. After malware removal, the information security department is asked to review the configuration and suggest changes to prevent this from happening again. Which of the following denotes the BEST way to mitigate future malware risk?
A. Deploy new perimeter firewalls at all stores with UTM functionality.
B. Change antivirus vendors at the store and the corporate office.
C. Move to a VDI solution that runs offsite from the same data center that hosts the new POS solution.
D. Deploy a proxy server with content filtering at the corporate office and route all traffic through it.

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.
