Which of the following is occurring on the network?

Which of the following would be used in forensic analysis of a compromised Linux system? (Select THREE).

The latest independent research shows that cyber attacks involving SCADA systems grew an average of 15% per year in each of the last four years, but that this
year’s growth has slowed to around 7%. Over the same time period, the number of attacks against applications has decreased or stayed flat each year. At the start
of the measure period, the incidence of PC boot loader or BIOS based attacks was negligible. Starting two years ago, the growth in the number of PC boot loader
attacks has grown exponentially. Analysis of these trends would seem to suggest which of the following strategies should be employed?

An administrator has enabled salting for users’ passwords on a UNIX box. A penetration tester must attempt to retrieve password hashes. Which of the following
files must the penetration tester use to eventually obtain passwords on the system? (Select TWO).

A user is suspected of engaging in potentially illegal activities. Law enforcement has requested that the user continue to operate on the network as normal.
However, they would like to have a copy of any communications from the user involving certain key terms. Additionally, the law enforcement agency has requested
that the user’s ongoing communication be retained in the user’s account for future investigations. Which of the following will BEST meet the goals of law

enforcement?

A recently hired security administrator is advising developers about the secure integration of a legacy in-house application with a new cloud based processing
system. The systems must exchange large amounts of fixed format data such as names, addresses, and phone numbers, as well as occasional chunks of data in
unpredictable formats. The developers want to construct a new data format and create custom tools to parse and process the data. The security administrator
instead suggests that the developers:

A security analyst, Ann, states that she believes Internet facing file transfer servers are being attacked. Which of the following is evidence that would aid Ann in
making a case to management that action needs to be taken to safeguard these servers?

A pentester must attempt to crack passwords on a windows domain that enforces strong complex passwords. Which of the following would crack the MOST
passwords in the shortest time period?

ABC Company must achieve compliance for PCI and SOX. Which of the following would BEST allow the organization to achieve compliance and ensure security?
(Select THREE).

A security administrator has been asked to select a cryptographic algorithm to meet the criteria of a new application. The application utilizes streaming video that
can be viewed both on computers and mobile devices. The application designers have asked that the algorithm support the transport encryption with the lowest
possible performance overhead. Which of the following recommendations would BEST meet the needs of the application designers? (Select TWO).
