The correct choice is to use a secrets management service. Hardcoded database credentials in legacy application code are a critical vulnerability because they are exposed in version control, logs, and static analysis, making them a prime target during cloud migration. A secrets management service, such as AWS Secrets Manager or HashiCorp Vault, stores credentials securely, enables automatic rotation, and provides runtime access via API calls, eliminating the need to embed secrets in code and aligning with the principle of least privilege. On the CCSP exam, this question tests your understanding of secure development practices within the Software Development Security domain, often appearing as a trap where candidates mistakenly choose encryption of the code or environment variables alone—neither of which removes the embedded secret. Remember the mnemonic “Secrets Never Stay in Source” to recall that secrets management, not obfuscation, is the proper solution for hardcoded credentials.
CCSP Cloud Application Security Practice Question
This CCSP practice question tests your understanding of cloud application security. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is migrating a legacy application to the cloud. The application uses hardcoded database credentials. Which secure development practice should be implemented to address this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a secrets management service
Hardcoded database credentials in application code create a severe security risk because they are exposed in version control, logs, and static analysis. Using a secrets management service (e.g., AWS Secrets Manager, HashiCorp Vault, Azure Key Vault) allows credentials to be stored securely, rotated automatically, and accessed at runtime via API calls, eliminating the need to embed secrets in code. This aligns with the principle of least privilege and secure credential management in cloud application security.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use code signing for all deployments
Why it's wrong here
Code signing ensures code integrity, not secret management.
✗
Implement input validation on all user inputs
Why it's wrong here
Input validation prevents injection attacks, not credential exposure.
✗
Enable encryption at rest for the database
Why it's wrong here
Encryption at rest protects data at rest, not credentials in code.
✓
Use a secrets management service
Why this is correct
Secrets management securely stores and rotates credentials, eliminating hardcoding.

Common exam traps
Common exam trap: answer the scenario, not the keyword
ISC2 often tests the distinction between 'protecting data at rest' (encryption) and 'protecting access credentials' (secrets management), leading candidates to mistakenly choose encryption at rest when the real issue is credential exposure in code.
Detailed technical explanation
How to think about this question
Secrets management services typically use a combination of envelope encryption (e.g., AWS KMS with a master key) and access control policies (e.g., IAM roles) to secure secrets at rest and in transit. At runtime, the application authenticates to the secrets manager using a short-lived token (e.g., via AWS STS or a JWT), retrieves the credential, and caches it in memory—never writing it to disk or logs. A real-world scenario is a microservice that rotates its database password every 90 minutes; without a secrets manager, each instance would need to be redeployed with the new password, causing downtime.

Real-world example
How this comes up in practice
A developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
