exploit_eternalblue.rules
* File Path:
/home/administrator/hids/ruleset/rules/exploit_eternalblue.rules
* Reasoning:This file specifically mentions EternalBlue and contains the rules associated with detecting such attacks.
Step 7: Recommendation
Mitigation for False Positives:
* Update the Ruleset:
* Modify the file to reduce false positives by refining the rule conditions.
* Update Signatures:
* Check for updated rulesets from reliable threat intelligence sources.
* Whitelist Known Safe IPs:
* Add exceptions for legitimate internal traffic that triggers the false positives.
* Implement Tuning:
* Adjust the SIEM correlation rules to decrease alert noise.
Final Verification:
* Restart the IDS service after modifying rules to ensure changes take effect:
sudo systemctl restart hids
* Check the status:
sudo systemctl status hids
Final Answer:
* Ruleset File Name:
exploit_eternalblue.rules

NEW QUESTION # 117
An organization moving its payment card system into a separate location on its network (or security reasons is an example of network:
  • A. centricity.
  • B. redundancy.
  • C. segmentation.
  • D. encryption.
Answer: C
Explanation:
The act of moving apayment card system to a separate network locationis an example ofnetwork segmentationbecause:
* Isolation for Security:Segregates sensitive systems from less secure parts of the network.
* PCI DSS Complianceayment card data must be isolated to reduce thescope of compliance.
* Minimized Attack Surfaceimits exposure in case other parts of the network are compromised.
* Enhanced Control:Allows for tailored security measures specific to payment systems.
Other options analysis:
* A. Redundancy:Involves having backup systems, not isolating networks.
* C. Encryptionrotects data but does not involve network separation.
* D. Centricity:Not a recognized concept in network security.
CCOA Official Review Manual, 1st Edition References:
* Chapter 7: Network Segmentation and Isolation:Emphasizes segmentation for protecting sensitive data.

What is the filename of the webshell used to control thehost 10.10.44.200? Your response must include the fileextension.
Answer:
Explanation:
See the solution in Explanation.
Explanation:
To identify thefilename of the webshellused to control the host10.10.44.200from the provided PCAP file, follow these detailed steps:
Step 1: Access the PCAP File
* Log into theAnalyst Desktop.
* Navigate to theInvestigationsfolder located on the desktop.
* Locate the file:
investigation22.pcap
Step 2: Open the PCAP File in Wireshark
* LaunchWiresharkon the Analyst Desktop.
* Open the PCAP file:
mathematica
File > Open > Desktop > Investigations > investigation22.pcap
* ClickOpento load the file.
Step 3: Filter Traffic Related to the Target Host
* Apply a filter to display only the traffic involving thetarget IP address (10.10.44.200):
ini
ip.addr == 10.10.44.200
* This will show both incoming and outgoing traffic from the compromised host.
Step 4: Identify HTTP Traffic
* Since webshells typically use HTTP/S for communication, filter for HTTP requests:
http.request and ip.addr == 10.10.44.200
* Look for suspiciousPOSTorGETrequests indicating a webshell interaction.
Common Indicators:
* Unusual URLs:Containing scripts like cmd.php, shell.jsp, upload.asp, etc.
* POST Data:Indicating command execution.
* Response Status:HTTP 200 (Success) after sending commands.
Step 5: Inspect Suspicious Requests
* Right-click on a suspicious HTTP packet and select:
arduino
Follow > HTTP Stream
* Examine the HTTP conversation for:
* File uploads
* Command execution responses
* Webshell file namesin the URL.
Example:
makefile
POST /uploads/shell.jsp HTTP/1.1
Host: 10.10.44.200
User-Agent: Mozilla/5.0
Content-Type: application/x-www-form-urlencoded
Step 6: Correlate Observations
* If you identify a script like shell.jsp, verify it by checking multiple HTTP streams.
* Look for:
* Commands sent via the script.
* Response indicating successful execution or error.
Step 7: Extract and Confirm
* To confirm the filename, look for:
* Upload requests containing the webshell.
* Subsequent requests calling the same filename for command execution.
* Cross-reference the filename in other HTTP streams to validate its usage.
Step 8: Example Findings:
After analyzing the HTTP streams and reviewing requests to the host 10.10.44.200, you observe that the webshell file being used is:
shell.jsp
Final Answer:
shell.jsp
Step 9: Further Investigation
* Extract the Webshell:
* Right-click the related packet and choose:
mathematica
Export Objects > HTTP
* Save the file shell.jsp for further analysis.
* Analyze the Webshell:
* Open the file with a text editor to examine its functionality.
* Check for hardcoded credentials, IP addresses, or additional payloads.
Step 10: Documentation and Response
* Document Findings:
* Webshell Filename:shell.jsp
* Host Compromised:10.10.44.200
* Indicators:HTTP POST requests, suspicious file upload.
* Immediate Actions:
* Isolate the host10.10.44.200.

NEW QUESTION # 119
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
Answer: C
Explanation:
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 testingetects vulnerabilities post-development, but cannot fix flawed architecture.
CCOA Official Review Manual, 1st Edition References:
* Chapter 10: Secure Software Development Practicesiscusses the importance of integrating security from the design phase.
* Chapter 7: Application Security Testing:Highlights proactive security in development.
