Question 1:
Which of the following would be used to prevent a firmware downgrade?

A. A. TPM
B. B. HSM
C. C. SED
D. D. Efuse

Correct Answer: D

Explanation
OBJ-4.2: eFUSE is an Intel-designed mechanism to allow software instructions to blow a transistor in the hardware chip. One use of this is to prevent firmware downgrades, implemented on some game consoles
and smartphones. Each time the firmware is upgraded, the updater blows an eFUSE. When there is a firmware update, the updater checks that the number of blown eFUSEs is not less than the firmware version
number. A self-encrypting drive (SED) uses cryptographic operations performed by the drive controller to encrypt a storage device’s contents. A trusted platform module (TPM) is a specification for hardware-based storage of digital certificates, cryptographic keys, hashed passwords, and other user and platform identification information. The TPM is implemented either as part of the chipset or as an embedded
function of the CPU. A hardware security module (HSM) is an appliance for generating and storing cryptographic keys. An HSM solution may be less susceptible to tampering and insider threats than
software-based storage.

Question 2
After 9 months of C++ programming, the team at Whammiedyne systems has released their new software application. Within just 2 weeks of release, though, the security team discovered multiple
serious vulnerabilities in the application that must be corrected. To retrofit the source code to include the required security controls will take 2 months of labor and will cost $100,000. Which
development framework should Whammiedyne use in the future to prevent this situation from occurring in other projects?

A. A. Agile Model
B. B. DevOps
C. C. Waterfall Model
D. D. DevSecOps

Correct Answer: D

Explanation
OBJ-3.4: DevSecOps is a combination of software development, security operations, and systems operations and refers to the practice of integrating each discipline with the others. DevSecOps approaches
are generally better postured to prevent problems like this because security is built-in during the development instead of retrofitting the program afterward. The DevOps development model incorporates
IT staff but does not include security personnel. The agile software development model focuses on iterative and incremental development to account for evolving requirements and expectations. The waterfall
software development model cascades the phases of the SDLC so that each phase will start only when all of the tasks identified in the previous phase are complete. A team of developers can make secure software using either the waterfall or agile model. Therefore, they are not the right answers to solve this issue.

Question 3:
Which of the following secure coding best practices ensures a character like < is translated into the &lt string when writing to an HTML page?

A. A. Output encoding
B. B. Error handling
C. C. Session management
D. D. Input validation

Correct Answer: A

Explanation
OBJ-2.2: Output encoding involves translating special characters into some different but equivalent form that is no longer dangerous in the target interpreter, for example, translating the < character into the &lt;
string when writing to an HTML page. Input validation is performed to ensure only properly formed data is entering the workflow in an information system, preventing malformed data from persisting in the database and triggering the malfunction of various downstream components. Improper error handling can introduce various security problems where detailed internal error messages such as stack traces, database dumps, and error codes are displayed to an attacker. The session management implementation defines the exchange mechanism that will be used between the user and the web application to share and continuously exchange the session ID.

Question 4
Which of the following tools is useful for capturing Windows memory data for forensic analysis?

A. A. dd
B. B. Memdump
C. C. Wireshark
D. D. Nessus

Correct Answer: B

Explanation
OBJ-4.4: The Memdump, Volatility framework, DumpIt, and EnCase are examples of Windows memory capture tools for forensic use. The dd tool is used to conduct forensic disk images. Wireshark is used for
packet capture and analysis. Nessus is a commonly used vulnerability scanner.

Question 5
Hilda needs a cost-effective backup solution that would allow for the restoration of data within a 24 hour RPO. The disaster recovery plan requires that backups occur during a specific timeframe each
week, and then the backups should be transported to an off-site facility for storage. What strategy should Hilda choose to BEST meet these requirements?

A. A. Create a daily incremental backup to tape
B. B. Create disk-to-disk snapshots of the server every hour
C. C. Conduct full backups daily to tape
D. D. Configure replication of the data to a set of servers located at a hot site


Correct Answer: A

Explanation
OBJ-5.2: Since the RPO must be within 24 hours, daily or hourly backups must be conducted. Since the requirement is for backups to be conducted at a specific time each week, hourly snapshots would not meet this requirement and are not easily transported since they are being conducted as a disk-to-disk backup. Replication to a hot site environment also doesn’t allow for transportation of the data to an off-site facility for storage, and replication would continuously occur throughout the day. Therefore, a daily incremental backup should be conducted since it will require the least amount of time to conduct. The tapes could be easily transported for storage and restored incrementally from tape since the last full backup was conducted.
