Robust background checks provide protection against:
  • A. distributed dental of service (DDoS) attacks.
  • B. insider threats.
  • C. ransomware.
  • D. phishing.
Answer: B
Explanation:
Robust background checks help mitigateinsider threatsby ensuring that individuals withaccess to sensitive data or critical systemsdo not have a history of risky or malicious behavior.
* Screening:Identifies red flags like past criminal activity or suspicious financial behavior.
* Trustworthiness Assessment:Ensures that employees handling sensitive information have a proven history of integrity.
* Insider Threat Mitigation:Helps reduce the risk of data theft, sabotage, or unauthorized access.
* Periodic Rechecks:Maintain ongoing security by regularly updating background checks.
Incorrect Options:
* A. DDoS attacks:Typically external; background checks do not mitigate these.
* C. Phishing:An external social engineering attack, unrelated to employee background.
* D. Ransomware:Generally spread via malicious emails or compromised systems, not insider actions.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 4, Section "Insider Threat Management," Subsection "re-Employment Screening" - Background checks are vital in identifying potential insider threats before hiring.

NEW QUESTION # 26
Which of the following is MOST likely to result from a poorly enforced bring your own device (8YOD) policy?
  • A. Weak passwords
  • B. Unapproved social media posts
  • C. Network congestion
  • D. Shadow IT
Answer: D
Explanation:
A poorly enforcedBring Your Own Device (BYOD)policy can lead to the rise ofShadow IT, where employees use unauthorized devices, software, or cloud services without IT department approval. This often occurs because:
* Lack of Policy Clarity:Employees may not be aware of which devices or applications are approved.
* Absence of Monitoring:If the organization does not track personal device usage, employees may introduce unvetted apps or tools.
* Security Gapsersonal devices may not meet corporate security standards, leading to data leaks and vulnerabilities.
* Data Governance Issues:IT departments lose control over data accessed or stored on unauthorized devices, increasing the risk of data loss or exposure.
Other options analysis:
* A. Weak passwords:While BYOD policies might influence password practices, weak passwords are not directly caused by poor BYOD enforcement.
* B. Network congestion:Increased device usage might cause congestion, but this is more of a performance issue than a security risk.
* D. Unapproved social media posts:While possible, this issue is less directly related to poor BYOD policy enforcement.
CCOA Official Review Manual, 1st Edition References:
* Chapter 3: Asset and Device Managementiscusses risks associated with poorly managed BYOD policies.
* Chapter 7: Threat Monitoring and Detection:Highlights how Shadow IT can hinder threat detection.

NEW QUESTION # 27
The network team has provided a PCAP file withsuspicious activity located in the Investigations folderon the Desktop titled, investigation22.pcap.
What date was the webshell accessed? Enter the formatas YYYY-MM-DD.
Answer:
Explanation:
See the solution in Explanation.
Explanation:
To determine thedate the webshell was accessedfrom theinvestigation22.pcapfile, follow these detailed steps:
Step 1: Access the PCAP File
* Log into the Analyst Desktop.
* Navigate to theInvestigationsfolder on the desktop.
* Locate the file:
investigation22.pcap
Step 2: Open the PCAP File in Wireshark
* LaunchWireshark.
* Open the PCAP file:
mathematica
File > Open > Desktop > Investigations > investigation22.pcap
* ClickOpento load the file.
Step 3: Filter for Webshell Traffic
* Since webshells typically useHTTP/Sto communicate, apply a filter:
http.request or http.response
* Alternatively, if you know the IP of the compromised host (e.g.,10.10.44.200), use:
nginx
http and ip.addr == 10.10.44.200
* PressEnterto apply the filter.
Step 4: Identify Webshell Activity
* Look for HTTP requests that include:
* Common Webshell Filenames:shell.jsp, cmd.php, backdoor.aspx, etc.
* Suspicious HTTP Methods:MainlyPOSTorGET.
* Right-click a suspicious packet and choose:
arduino
Follow > HTTP Stream
* Inspect the HTTP headers and content to confirm the presence of a webshell.
Step 5: Extract the Access Date
* Look at theHTTP request/response header.
* Find theDatefield orTimestampof the packet:
* Wireshark displays timestamps on the left by default.
* Confirm theHTTP streamincludes commands or uploads to the webshell.
Example HTTP Stream:
POST /uploads/shell.jsp HTTP/1.1
Host: 10.10.44.200
User-Agent: Mozilla/5.0
Date: Mon, 2024-03-18 14:35:22 GMT
Step 6: Verify the Correct Date
* Double-check other HTTP requests or responses related to the webshell.
* Make sure thedate fieldis consistent across multiple requests to the same file.
2024-03-18
Step 7: Document the Finding
* Date of Access:2024-03-18
* Filename:shell.jsp (as identified earlier)
* Compromised Host:10.10.44.200
* Method of Access:HTTP POST
Step 8: Next Steps
* Isolate the Affected Host:
* Remove the compromised server from the network.
* Remove the Webshell:
rm /path/to/webshell/shell.jsp
* Analyze Web Server Logs:
* Correlate timestamps with access logs to identify the initial compromise.
* Implement WAF Rules:
* Block suspicious patterns related to file uploads and webshell execution.

NEW QUESTION # 29
An insecure continuous integration and continuous delivery (CI/CD) pipeline would MOST likely lead to:
  • A. security monitoring failures.
  • B. broken access control.
  • C. software Integrity failures.
  • D. browser compatibility Issues.
Answer: C
Explanation:
An insecure CI/CD pipeline can lead to software integrity failures primarily due to the risk of:
* Code Injection:Unauthenticated or poorly controlled access to the CI/CD pipeline can allow attackers to inject malicious code during build or deployment.
* Compromised Dependencies:Automated builds may incorporate malicious third-party libraries or components, compromising the final product.
* Insufficient Access Control:Without proper authentication and authorization mechanisms, unauthorized users might modify build configurations or artifacts.
* Pipeline Poisoning:Attackers can alter the pipeline to include vulnerabilities or backdoors.
Due to the above risks, software integrity can be compromised, resulting in the distribution of tampered or malicious software.
Incorrect Options:
* B. Broken access control:This is a more general web application security issue, not specific to CI/CD pipelines.
* C. Security monitoring failures:While possible, this is not the most direct consequence of CI/CD pipeline insecurities.
* D. Browser compatibility Issues:This is unrelated to CI/CD security concerns.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 6, Section "DevSecOps and CI/CD Security", Subsection "Risks and Vulnerabilities in CI
/CD Pipelines" - Insecure CI/CD pipelines can compromise software integrity due to code injection and dependency attacks.
