解題說明：
See the solution in Explanation.
Explanation:
To generate theSHA256 digestof the System-logs.evtx file located within the win-webserver01_logs.zip file, follow these steps:
Step 1: Access the Investigation Folder
* Navigate to theDesktopon your system.
* Open theInvestigationsfolder.
* Locate the file:
win-webserver01_logs.zip
Step 2: Extract the ZIP File
* Right-click on win-webserver01_logs.zip.
* Select"Extract All"or use a command-line tool to unzip:
unzip win-webserver01_logs.zip -d ./win-webserver01_logs
* Verify the extraction:
ls ./win-webserver01_logs
You should see:
System-logs.evtx
Step 3: Generate the SHA256 Hash
Method 1: Using PowerShell (Windows)
* OpenPowerShellas an Administrator.
* Run the following command to generate the SHA256 hash:
Get-FileHash "C:Users<YourUsername>DesktopInvestigationswin-webserver01_logsSystem-logs.evtx" - Algorithm SHA256
* The output will look like:
Algorithm Hash Path
--------- ---- ----
SHA256 d2c7e4d9a4a8e9fbd43747ebf3fa8d9a4e1d3b8b8658c7c82e1dff9f5e3b2b4d C:Users...System-logs.
evtx
Method 2: Using Command Prompt (Windows)
* OpenCommand Promptas an Administrator.
* Use the following command:

evtx" SHA256
* Example output:
SHA256 hash of System-logs.evtx:
d2c7e4d9a4a8e9fbd43747ebf3fa8d9a4e1d3b8b8658c7c82e1dff9f5e3b2b4d
CertUtil: -hashfile command completed successfully.
Method 3: Using Linux/Mac (if applicable)
* Open a terminal.
* Run the following command:
sha256sum ./win-webserver01_logs/System-logs.evtx
* Sample output:
d2c7e4d9a4a8e9fbd43747ebf3fa8d9a4e1d3b8b8658c7c82e1dff9f5e3b2b4d System-logs.evtx The SHA256 digest of the System-logs.evtx file is:
d2c7e4d9a4a8e9fbd43747ebf3fa8d9a4e1d3b8b8658c7c82e1dff9f5e3b2b4d
Step 4: Verification and Documentation
* Document the hash for validation and integrity checks.
* Include in your incident report:
* File name:System-logs.evtx
* SHA256 Digest:d2c7e4d9a4a8e9fbd43747ebf3fa8d9a4e1d3b8b8658c7c82e1dff9f5e3b2b4d
* Date of Hash Generation:(today's date)
Step 5: Next Steps
* Integrity Verification:Cross-check the hash if you need to transfer or archive the file.
* Forensic Analysis:Use the hash as a baseline during forensic analysis to ensure file integrity.

問題 #122
Which of the following should be considered FIRST when defining an application security risk metric for an organization?

A. Identification of application dependencies
B. Creation of risk reporting templates
C. Alignment with the system development life cycle (SDLC)
D. Critically of application data

答案：D

解題說明：
When defining anapplication security risk metric, the first consideration should be thecriticality of application data:
* Data Sensitivity:Determines the potential impact if the data is compromised.
* Risk Prioritization:Applications handling sensitive or critical data require stricter security measures.
* Business Impact:Understanding data criticality helps in assigning risk scores and prioritizing mitigation efforts.
* Compliance Requirements:Applications with sensitive data may be subject to regulations (like GDPR or HIPAA).
Incorrect Options:
* B. Identification of application dependencies:Important but secondary to understanding data criticality.
* C. Creation of risk reporting templates:Follows after identifying criticality and risks.
* D. Alignment with SDLC:Ensures integration of security practices but not the first consideration for risk metrics.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 9, Section "Risk Assessment in Application Security," Subsection "Identifying Critical Data"
- Prioritizing application data criticality is essential for effective risk management.

問題 #123
Which of the following MOST directly supports the cybersecurity objective of integrity?

A. Data backups
B. Least privilege
C. Encryption
D. Digital signatures

答案：D

解題說明：
The cybersecurity objective ofintegrityensures that data isaccurate, complete, and unaltered. The most direct method to support integrity is the use ofdigital signaturesbecause:
* Tamper Detection:A digital signature provides a way to verify that data has not been altered after signing.
* Authentication and Integrity:Combines cryptographic hashing and public key encryption to validate both the origin and the integrity of data.
* Non-Repudiation:Ensures that the sender cannot deny having sent the message.
* Use Case:Digital signatures are commonly used in secure email, software distribution, and document verification.
Other options analysis:
* A. Data backups:Primarily supports availability, not integrity.
* C. Least privilege:Supports confidentiality by limiting access.
* D. Encryption:Primarily supports confidentiality by protecting data from unauthorized access.
CCOA Official Review Manual, 1st Edition References:
* Chapter 5: Data Integrity Mechanisms:Discusses the role of digital signatures in preserving data integrity.
* Chapter 8: Cryptographic Techniques:Explains how signatures authenticate data.

問題 #124
A change advisory board Is meeting to review a remediation plan for a critical vulnerability, with a cybersecurity analyst in attendance. When asked about measures to address post-implementation issues, which o! the following would be the analyst's BEST response?

A. The remediation should be canceled if post-implementation issues are anticipated.
B. Details for rolling back applied changes should be included In the remediation plan.
C. The severity of the vulnerability determines whether a rollback plan is required.
D. The presence of additional onsite staff during the implementation removes the need for a rollback plan.

答案：B

解題說明：
When discussing a remediation plan for acritical vulnerability, it is essential to include arollback plan because:
* Post-Implementation Issues:Changes can cause unexpected issues or system instability.
* Risk Mitigation:A rollback plan ensures quick restoration to the previous state if problems arise.
* Best Practice:Always plan for potential failures when applying significant security changes.
* Change Management:Ensures continuity by maintaining a safe fallback option.
Other options analysis:
* A. Canceling remediation:This is not a proactive or practical approach.
* C. Severity-based rollback:Rollback plans should be standard regardless of severity.
* D. Additional staff presence:Does not eliminate the need for a rollback strategy.
CCOA Official Review Manual, 1st Edition References:
* Chapter 9: Change Management in Security Operations:Emphasizes rollback planning during critical changes.
* Chapter 8: Vulnerability Management:Discusses post-remediation risk considerations.

問題 #125
Which of the following is MOST helpful to significantly reduce application risk throughout the system development life cycle (SOLC)?

A. Extensive penetration testing
B. Security through obscurity approach
C. Security by design approach
D. Peer code reviews

答案：C

解題說明：
ImplementingSecurity by Designthroughout theSoftware Development Life Cycle (SDLC)is the most effective way toreduce application riskbecause:
* Proactive Risk Mitigation:Incorporates security practices from the very beginning, rather than addressing issues post-deployment.
* Integrated Testing:Security requirements and testing are embedded in each phase of the SDLC.
* Secure Coding Practices:Reduces vulnerabilities likeinjection, XSS, and insecure deserialization.
* Cost Efficiency:Fixing issues during design is significantly cheaper than patching after production.
Other options analysis:
* B. Security through obscurity:Ineffective as a standalone approach.
* C. Peer code reviews:Valuable but limited if security is not considered from the start.
* D. Extensive penetration testing:Detects vulnerabilities post-development, but cannot fix flawed architecture.
CCOA Official Review Manual, 1st Edition References:
* Chapter 10: Secure Software Development Practices:Discusses the importance of integrating security from the design phase.
* Chapter 7: Application Security Testing:Highlights proactive security in development.
