NEW QUESTION # 21
Which of the following is the PRIMARY risk associated with cybercriminals eavesdropping on unencrypted network traffic?

A. Data deletion
B. Data exfiltration
C. Data notification
D. Data exposure

Answer: D

Explanation:
Theprimary riskassociated with cybercriminalseavesdropping on unencrypted network trafficisdata exposurebecause:
* Interception of Sensitive Data:Unencrypted traffic can be easily captured using tools likeWiresharkor tcpdump.
* Loss of Confidentiality:Attackers can viewclear-text data, includingpasswords, personal information, or financial details.
* Common Attack Techniques:Includespacket sniffingandMan-in-the-Middle (MitM)attacks.
* Mitigation:Encrypt data in transit using protocols likeHTTPS, SSL/TLS, or VPNs.
Other options analysis:
* A. Data notification:Not relevant in the context of eavesdropping.
* B. Data exfiltration:Usually involves transferring data out of the network, not just observing it.
* D. Data deletion:Unrelated to passive eavesdropping.
CCOA Official Review Manual, 1st Edition References:
* Chapter 4: Network Security Operations:Highlights the risks of unencrypted traffic.
* Chapter 8: Threat Detection and Monitoring:Discusses eavesdropping techniques and mitigation.

NEW QUESTION # 22
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 presence of additional onsite staff during the implementation removes the need for a rollback plan.
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 remediation should be canceled if post-implementation issues are anticipated.

Answer: B

Explanation:
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.

NEW QUESTION # 24
The user of the Accounting workstation reported thattheir calculator repeatedly opens without their input.
The following credentials are used for thisquestion.
Username:Accounting
Password:1x-4cc0unt1NG-x1
Using the provided credentials, SSH to the Accountingworkstation and generate a SHA256 checksum of the filethat triggered RuleName Suspicious PowerShell usingeither certutil or Get-FileHash of the file causing theissue. Copy the hash and paste it below.

Answer:

Explanation:
See the solution in Explanation.
Explanation:
To generate theSHA256 checksumof the file that triggeredRuleName: Suspicious PowerShellon the Accounting workstation, follow these detailed steps:
Step 1: Establish an SSH Connection
* Open a terminal on your system.
* Use the provided credentials to connect to theAccounting workstation:
ssh Accounting@<Accounting_PC_IP>
* Replace <Accounting_PC_IP> with the actual IP address of the workstation.
* Enter the password when prompted:
1x-4cc0unt1NG-x1
Step 2: Locate the Malicious File
* Navigate to the typical directory where suspicious scripts are stored:
cd C:UsersAccountingAppDataRoaming
* List the contents to identify the suspicious file:
dir
* Look for a file related toPowerShell(e.g., calc.ps1), as the issue involved thecalculator opening repeatedly.
Step 3: Verify the Malicious File
* To ensure it is the problematic file, check for recent modifications:
powershell
Get-ChildItem -Path "C:UsersAccountingAppDataRoaming" -Recurse | Where-Object { $_.LastWriteTime
-ge (Get-Date).AddDays(-1) }
* This will list files modified within the last 24 hours.
* Check file properties:
powershell
Get-Item "C:UsersAccountingAppDataRoamingcalc.ps1" | Format-List *
* Confirm it matches the file flagged byRuleName: Suspicious PowerShell.
Step 4: Generate the SHA256 Checksum
Method 1: Using PowerShell (Recommended)
* Run the following command to generate the hash:
powershell
Get-FileHash "C:UsersAccountingAppDataRoamingcalc.ps1" -Algorithm SHA256
* Output Example:
mathematica
Algorithm Hash Path
--------- ---- ----
SHA256 d2c7e4d9a4a8e9fbd43747ebf3fa8d9a4e1d3b8b8658c7c82e1dff9f5e3b2b4d C:
UsersAccountingAppDataRoamingcalc.ps1
Method 2: Using certutil (Alternative)
* Run the following command:
cmd
certutil -hashfile "C:UsersAccountingAppDataRoamingcalc.ps1" SHA256
* Example Output:
SHA256 hash of calc.ps1:
d2c7e4d9a4a8e9fbd43747ebf3fa8d9a4e1d3b8b8658c7c82e1dff9f5e3b2b4d
