NEW QUESTION # 49
An enterprise is deploying APIs that utilize a private key and a public key to ensure the connection string is protected. To connect to the API, customers must use the private key.
Which of the following would BEST secure the REST API connection to the database while preventing the use of a hard-coded string in the request string?
- A. Sign the key with DSA.
- B. Deploy MFA for the service accounts.
- C. Implement a VPN for all APIs.
- D. Utilize HMAC for the keys.
Answer: D
Explanation:
Explanation
Utilizing HMAC (hash-based message authentication code) for the keys is the best option for securing the REST API connection to the database while preventing the use of a hard-coded string in the request string.
HMAC is a technique that uses a secret key and a hash function to generate a code that can verify the authenticity and integrity of a message, preventing unauthorized modifications or tampering. Utilizing HMAC for the keys can prevent the use of a hard-coded string in the request string, as it can dynamically generate a unique code for each request based on the secret key and the message content, making it difficult to forge or replay. Implementing a VPN (virtual private network) for all APIs is not a good option for securing the REST API connection to the database, as it could introduce latency or performance issues for API requests, as well as not prevent the use of a hard-coded string in the request string. Signing the key with DSA (Digital Signature Algorithm) is not a good option for securing the REST API connection to the database, as it could be vulnerable to attacks or forgery if the key is compromised or weak, as well as not prevent the use of a hard-coded string in the request string. Deploying MFA (multi-factor authentication) for the service accounts is not a good option for securing the REST API connection to the database, as it could affect the usability or functionality of API requests, as well as not prevent the use of a hard-coded string in the request string.

NEW QUESTION # 50
Which of the following is the reason why security engineers often cannot upgrade the security of embedded facility automation systems?
- A. They lack EEPROM.
- B. They are constrained by available compute.
- C. They lack X86-64 processors.
- D. They are not logic-bearing devices.
Answer: B
Explanation:
Embedded facility automation systems are often difficult to upgrade because they are constrained by available compute. These systems typically have limited processing power, memory, and storage, which restricts the ability to implement modern security measures, such as encryption, software updates, or advanced security controls. Security engineers may be unable to apply patches or updates without exceeding the system's capacity. CASP+ discusses the challenges posed by resource-constrained devices, particularly in embedded systems and IoT environments, where upgrading security can be difficult due to hardware limitations.

NEW QUESTION # 52
An application engineer is using the Swagger framework to leverage REST APIs to authenticate endpoints. The engineer is receiving HTTP 403 responses. Which of the following should the engineer do to correct this issue? (Choose two.)
- A. Leverage OAuth for authentication.
- B. Leverage LDAP for authentication.
- C. Obtain a public key.
- D. Leverage Kerberos for authentication
- E. Obtain a hash value.
- F. Obtain a security token.
Answer: A,F
Explanation:
The HTTP 403 error indicates that the engineer does not have the appropriate permissions to access the endpoint. To correct this, the engineer should obtain a security token and leverage OAuth for authentication. OAuth is a widely used authorization framework for securing API endpoints, and obtaining a security token is a key step in authenticating API requests. These two steps will ensure the correct authentication process is followed, allowing access to the required API resources.

NEW QUESTION # 55
A security administrator wants to detect a potential forged sender claim in tt-e envelope of an email. Which of the following should the security administrator implement? (Select TWO).
- A. DMARC
- B. TLS
- C. MX record
- D. SPF
- E. DNSSEC
- F. S/MIME
Answer: A,D
Explanation:
DMARC (Domain-based Message Authentication, Reporting and Conformance) and SPF (Sender Policy Framework) are two mechanisms that can help detect and prevent email spoofing, which is the creation of email messages with a forged sender address. DMARC allows a domain owner to publish a policy that specifies how receivers should handle messages that fail authentication tests, such as SPF or DKIM (DomainKeys Identified Mail). SPF allows a domain owner to specify which mail servers are authorized to send email on behalf of their domain. By checking the DMARC and SPF records of the sender's domain, a receiver can verify if the email is from a legitimate source or not. Verified Reference:

NEW QUESTION # 56
An analyst is working to address a potential compromise of a corporate endpoint and discovers the attacker accessed a user's credentials. However, it is unclear if the system baseline was modified to achieve persistence. Which of the following would most likely support forensic activities in this scenario?
- A. Bit-level disk duplication
- B. SCAP scanner
- C. Side-channel analysis
- D. Software composition analysis
Answer: A
Explanation:
Bit-level disk duplication creates an exact copy of the storage device, preserving the system's state for in- depth forensic analysis. This helps identify any unauthorized changes to the baseline or other artifacts of compromise. This aligns with CASP+ objective 5.2, which emphasizes conducting forensic activities and ensuring evidence integrity during investigations.

NEW QUESTION # 57
A company moved its on-premises services to the cloud. Although a recent audit verified that data throughout the cloud service is properly classified and documented, other systems are unable to act or filter based on this information. Which of the following should the company deploy to allow other cloud-based systems to consume this information?
- A. Log scraping
- B. Data mapping
- C. Data labeling
- D. Resource tagging
Answer: C
Explanation:
Step by Step
Data labeling enables metadata tagging for data classification, which allows systems to filter, act, and enforce policies based on the labels.
Data mapping is used for understanding data flows but does not support automation.
Log scraping and resource tagging are unrelated to enabling system actions based on data classification.
NEW QUESTION # 58

NEW QUESTION # 59
A security architect works for a manufacturing organization that has many different branch offices. The architect is looking for a way to reduce traffic and ensure the branch offices receive the latest copy of revoked certificates issued by the CA at the organization's headquarters location. The solution must also have the lowest power requirement on the CA.
Which of the following is the BEST solution?
- A. Send the new CRLs by using GPO.
- B. Deploy an RA on each branch office.
- C. Configure clients to use OCSP.
- D. Use Delta CRLs at the branches.
Answer: C
Explanation:
Reference:
OCSP (Online Certificate Status Protocol) is a protocol that allows clients to check the revocation status of certificates in real time by querying an OCSP responder server. This would enable the organization to determine whether it is vulnerable to the active campaign utilizing a specific vulnerability, as it would show if any certificates have been compromised or revoked. Deploying an RA (registration authority) on each branch office may not help with checking the revocation status of certificates, as an RA is responsible for verifying the identity of certificate applicants, not issuing or revoking certificates. Using Delta CRLs (certificate revocation lists) at the branches may not provide timely or accurate information on certificate revocation status, as CRLs are updated periodically and may not reflect the latest changes. Implementing an inbound BGP (Border Gateway Protocol) prefix list may not help with checking the revocation status of certificates, as BGP is a protocol for routing network traffic between autonomous systems, not verifying certificates.
