Q17. - (Topic 4)
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.
Answer: C

A storage as a service company implements both encryption at rest as well as encryption in transit of customers’ data. The security administrator is concerned with the overall security of the encrypted customer data stored by the company servers and wants the development team to implement a solution that will strengthen the customer’s encryption key. Which of the following, if implemented, will MOST increase the time an offline password attack against the customers’ data would take?
A. key = NULL ; for (int i=0; i<5000; i++) { key = sha(key + password) }
B. password = NULL ; for (int i=0; i<10000; i++) { password = sha256(key) }
C. password = password + sha(password+salt) + aes256(password+salt)
D. key = aes128(sha256(password), password))
Answer: A
