CAS-004 PDF Questions, CAS-004 Test Quiz

ActualTestsIT regularly updates CompTIA Advanced Security Practitioner (CASP+) Exam (CAS-004) practice exam material to ensure that it keeps in line with the test. In the same way, ActualTestsIT provides a free demo before you purchase so that you may know the quality of the CAS-004 dumps. Similarly, the CompTIA CAS-004 practice test creates an actual exam scenario on each and every step so that you may be well prepared before your actual CAS-004 examination time. Hence, it saves you time and money. ActualTestsIT provides three months of free updates if you purchase the CompTIA CAS-004 questions and the content of the examination changes after that.

Why is the CompTIA CAS-004 certification difficult to write?

The CompTIA CAS-004 exam is difficult to write because it tests your knowledge of today's complex computer technologies not your knowledge of those technologies from 4 years ago. Many IT professionals have complained that the CompTIA CAS-004 Certification Exam doesn't adequately test your knowledge of today's complex computer technologies and as a result they end up having to retake the exam several times before they pass.

CompTIA Advanced Security Practitioner (CASP+) Exam Sample Questions (Q521-Q526):

NEW QUESTION # 521
A security engineer estimates the company's popular web application experiences 100 attempted breaches per day. In the past four years, the company's data has been breached two times.
Which of the following should the engineer report as the ARO for successful breaches?

A. 0.5
B. 0
C. 1
D. 36,500

Answer: A

NEW QUESTION # 522
A software company is developing an application in which data must be encrypted with a cipher that requires the following:
Initialization vector

Low latency

Suitable for streaming

Which of the following ciphers should the company use?

A. Cipher block chaining
B. Cipher block chaining message authentication code
C. Electronic codebook
D. Cipher feedback

Answer: D

Explanation:
CFB mode is converting a block cipher into a type of stream cipher. The encryption algorithm is used as a key-stream generator to produce key-stream that is placed in the bottom register. This key stream is then XORed with the plaintext as in case of stream cipher.

NEW QUESTION # 523
Due to adverse events, a medium-sized corporation suffered a major operational disruption that caused its servers to crash and experience a major power outage. Which of the following should be created to prevent this type of issue in the future?

A. BIA
B. BCM
C. BCP
D. SLA
E. RTO

Answer: C

Explanation:
A Business Continuity Plan (BCP) is a set of policies and procedures that outline how an organization should respond to and recover from disruptions [1]. It is designed to ensure that critical operations and services can be quickly restored and maintained, and should include steps to identify risks, develop plans to mitigate those risks, and detail the procedures to be followed in the event of a disruption.

NEW QUESTION # 524
During a software assurance assessment, an engineer notices the source code contains multiple instances of strcpy. which does not verify the buffer length. Which of the following solutions should be integrated into the SDLC process to reduce future risks?

A. Perform DAST/SAST scanning before handoff to another team.
B. Perform a penetration test before moving to the next step of the SDLC.
C. Update the company's secure coding policy to exclude insecure functions.
D. Require custom IDS/IPS detection signatures for each type of insecure function found.

Answer: C

Explanation:
The source code in this scenario uses insecure functions like strcpy which are known for not checking buffer sizes, leading to buffer overflow vulnerabilities. The most effective solution is to update the company's secure coding policy to prohibit the use of insecure functions and replace them with safer alternatives, such as strncpy, which enforces buffer length checks. Integrating this change into the Software Development Life Cycle (SDLC) ensures that future code adheres to secure practices, thereby reducing the risk of vulnerabilities being introduced into production systems. This approach aligns with CASP+ guidelines that emphasize secure coding practices and policies to prevent common security flaws in software development.

NEW QUESTION # 525
A software development company needs to mitigate third-party risks to its software supply chain. Which of the following techniques should the company use in the development environment to best meet this objective?

A. Implementing a robust unit and regression-testing scheme
B. Performing software composition analysis
C. Requiring multifactor authentication
D. Establishing coding standards and monitoring for compliance

Answer: B

Explanation:
Software composition analysis (SCA) is the most effective method to mitigate third-party risks in a software supply chain. SCA tools analyze the open-source and third-party components used in software development to identify known vulnerabilities, outdated dependencies, or licensing issues. By integrating SCA into the development environment, the company can proactively address risks related to external libraries or codebases that may introduce vulnerabilities into the software supply chain. CASP+ emphasizes the importance of securing the supply chain, particularly by identifying and addressing risks introduced by third-party software components.
