- A
Restrict access to the file using operating system permissions.
Correct. Restricting access via OS permissions is a standard, platform-independent best practice that does not rely on deprecated Java features.
- B
Define a Java security policy file with FilePermission for the configuration file.
Why wrong: Incorrect. In Java 17, the Security Manager is deprecated for removal, so using a Java policy file is no longer a best practice.
- C
Make the file read-only at the OS level.
Why wrong: Incorrect. Making a file read-only does not prevent unauthorized users from reading it; proper access control requires restricting who can read the file.
- D
Store credentials in the source code and use encryption.
Why wrong: Incorrect. Storing credentials in source code is a major security risk, even with encryption, as encryption keys are often stored alongside the code.
1Z0-829 Security Manager Deprecation Practice Question
This 1Z0-829 practice question tests your understanding of java i/o api and securing applications. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. A key principle to apply: security Manager Deprecation. 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.

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Restrict access to the file using operating system permissions.
Option A is correct because restricting access to sensitive files using operating system permissions is a fundamental security practice that applies regardless of the Java version. In Java 17, the Security Manager is deprecated for removal (JEP 411), so relying on a Java security policy file (Option B) is no longer considered a best practice. OS-level permissions provide a robust, platform-native access control that does not depend on deprecated features. Options C and D are insufficient: making a file read-only does not prevent unauthorized access, and storing credentials in source code is highly insecure.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Candidates may think that using Java's Security Manager with a policy file is the best practice, but in Java 17 it is deprecated. The correct modern approach is to rely on OS-level permissions.
Detailed technical explanation
How to think about this question
The Java security manager uses a stack inspection algorithm to check each calling method's protection domain against the granted permissions in the policy file. FilePermission is evaluated with actions like 'read', 'write', 'delete', and 'execute', and the policy file is typically loaded at JVM startup via the `-Djava.security.policy` flag. In real-world scenarios, this is critical for applet containers or enterprise applications where the JVM must enforce access controls even when the OS user has broad privileges.
