The Information Security Officer (ISO) believes that the company has been targeted by cybercriminals and it is
under a cyber attack. Internal services that are normally available to the public via the Internet are inaccessible,
and employees in the office are unable to browse the Internet. The senior security engineer starts by reviewing
the bandwidth at the border router, and notices that the incoming bandwidth on the router’s external interface ismaxed out. The security engineer then inspects the following piece of log to try and determine the reason for
the downtime, focusing on the company’s external router’s IP which is 128.20.176.19:
11:16:22.110343 IP 90.237.31.27.19 > 128.20.176.19.19: UDP, length 1400
11:16:22.110351 IP 23.27.112.200.19 > 128.20.176.19.19: UDP, length 1400
11:16:22.110358 IP 192.200.132.213.19 > 128.20.176.19.19: UDP, length 1400
11:16:22.110402 IP 70.192.2.55.19 > 128.20.176.19.19: UDP, length 1400
11:16:22.110406 IP 112.201.7.39.19 > 128.20.176.19.19: UDP, length 1400
Which of the following describes the findings the senior security engineer should report to the ISO and the
BEST solution for service restoration?

Company XYZ has purchased and is now deploying a new HTML5 application. The company wants to hire a
penetration tester to evaluate the security of the client and server components of the proprietary web
application before launch. Which of the following is the penetration tester MOST likely to use while performing

A security firm is writing a response to an RFP from a customer that is building a new network based software
product. The firm’s expertise is in penetration testing corporate networks. The RFP explicitly calls for all
possible behaviors of the product to be tested, however, it does not specify any particular method to achieve
this goal. Which of the following should be used to ensure the security and functionality of the product? (Select
TWO).

There have been some failures of the company’s internal facing website. A security engineer has found the
WAF to be the root cause of the failures. System logs show that the WAF has been unavailable for 14 hours
over the past month, in four separate situations. One of these situations was a two hour scheduled
maintenance time, aimed at improving the stability of the WAF. Using the MTTR based on the last month’s
performance figures, which of the following calculations is the percentage of uptime assuming there were 722
hours in the month?
