NEW QUESTION # 77
An attacker has compromised a number of systems on an organization'snetwork andisexfiltrationdata Usingthe Domain Name System (DNS) queries. Whichof the following is the BEST mitigation strategy to prevent data exfiltration using this technique?
mitigation strategy to prevent data exfiltration using this technique?

A. Install a host-based Intrusion detection system (HIDS) on all systems in the network.
B. Implement Secure Sockets Layer (SSL) encryption on the DNS server.
C. Implement a DNS sinkhole to redirect alt DNS traffic to a dedicated server.
D. Block all outbound DNS traffic from the network.

Answer: C

Explanation:
ADNS sinkholeis a network security mechanism thatintercepts DNS queriesand redirects them to a controlled server.
* Functionality:Instead of allowing the exfiltration traffic to reach its intended destination, the sinkhole captures and analyzes the data.
* Detection and Prevention:Identifies and mitigates DNS-based data exfiltration attempts.
* Monitoring:Enables security teams to detect compromised systems attempting to exfiltrate data.
Incorrect Options:
* A. Implement SSL encryption on DNS server:Does not address data exfiltration through DNS queries.
* B. Host-based IDS (HIDS):Detects anomalies but cannot block DNS-based exfiltration.
* C. Block all outbound DNS traffic:Impractical as DNS is essential for network communication.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 8, Section "DNS Exfiltration Techniques," Subsection "Mitigation Strategies" - DNS sinkholes are effective for capturing and analyzing malicious DNS queries.

C. authorized consent is obtained.
D. the timeframe has been determined.

Answer: C

Explanation:
Before conducting apenetration test, themost crucial stepis to obtainauthorized consentfrom the client:
* Legal Compliance:Ensures the testing is lawful and authorized, preventing legal consequences.
* Clearance:Confirms that the client understands and agrees to the testing scope and objectives.
* Documentation:Signed agreements protect both the tester and client in case of issues during testing.
* Ethical Consideration:Performing tests without consent violates ethical hacking principles.
Incorrect Options:
* B. Determining timeframe:Important but secondary to legal consent.
* C. Defining scope:Necessary, but only after authorization.
* D. Estimating price:Relevant for contracts but not the primary security concern.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 8, Section "Ethical Hacking and Legal Considerations," Subsection "Authorization and Consent" - Proper authorization is mandatory before any penetration testing.

NEW QUESTION # 79

B. Track only those vulnerabilities that have been publicly disclosed.
C. Walt for external security researchers to report vulnerabilities
D. Implement regular vulnerability scanning and assessments.

Answer: D

Explanation:
Themost effective approach to tracking vulnerabilitiesis to regularly performvulnerability scans and assessmentsbecause:
* Proactive Identification:Regular scanning detects newly introduced vulnerabilities from software updates or configuration changes.
* Automated Monitoring:Modern scanning tools (like Nessus or OpenVAS) can automatically identify vulnerabilities in systems and applications.
* Assessment Reports:Provide prioritized lists of discovered vulnerabilities, helping IT teams address the most critical issues first.
* Compliance and Risk Management:Routine scans are essential for maintaining security baselines and compliance with standards (like PCI-DSS or ISO 27001).
Other options analysis:
* A. Wait for external reports:Reactive and risky, as vulnerabilities might remain unpatched.
* B. Rely on employee reporting:Inconsistent and unlikely to cover all vulnerabilities.
* D. Track only public vulnerabilities:Ignores zero-day and privately disclosed issues.

The CISO has received a bulletin from law enforcementauthorities warning that the enterprise may be at risk ofattack from a specific threat actor. Review the bulletin named CCOA Threat Bulletin.pdf on the Desktop.
Which of the following domain name(s) from the CCOAThreat Bulletin.pdf was contacted between 12:10 AMto 12:12 AM (Absolute) on August 17, 2024?

Answer:

Explanation:
See the solution in Explanation.
Explanation:
Step 1: Understand the Objective
Objective:
* Identify thedomain name(s)that werecontactedbetween:
12:10 AM to 12:12 AM on August 17, 2024
* Source of information:
CCOA Threat Bulletin.pdf
* File location:
~/Desktop/CCOA Threat Bulletin.pdf
Step 2: Prepare for Investigation
2.1: Ensure Access to the File
* Check if the PDF exists:
ls ~/Desktop | grep "CCOA Threat Bulletin.pdf"
* Open the file to inspect:
xdg-open ~/Desktop/CCOA Threat Bulletin.pdf
* Alternatively, convert to plain text for easier analysis:
pdftotext ~/Desktop/CCOA Threat Bulletin.pdf ~/Desktop/threat_bulletin.txt cat ~/Desktop/threat_bulletin.txt
2.2: Analyze the Content
* Look for domain names listed in the bulletin.
* Make note ofany domainsorURLsmentioned as IoCs (Indicators of Compromise).
* Example:
suspicious-domain.com
malicious-actor.net
threat-site.xyz
Step 3: Locate Network Logs
3.1: Find the Logs Directory
* The logs could be located in one of the following directories:
/var/log/
/home/administrator/hids/logs/
/var/log/httpd/
/var/log/nginx/
* Navigate to the likely directory:
cd /var/log/
ls -l
* Identify relevant network or DNS logs:
ls -l | grep -E "dns|network|http|nginx"
Step 4: Search Logs for Domain Contacts
4.1: Use the Grep Command to Filter Relevant Timeframe
* Since we are looking for connections between12:10 AM to 12:12 AMonAugust 17, 2024:
grep "2024-08-17 00:1[0-2]" /var/log/dns.log
* Explanation:
* grep "2024-08-17 00:1[0-2]": Matches timestamps between00:10and00:12.
* Replace dns.log with the actual log file name, if different.
4.2: Further Filter for Domain Names
* To specifically filter out the domains listed in the bulletin:
grep -E "(suspicious-domain.com|malicious-actor.net|threat-site.xyz)" /var/log/dns.log
* If the logs are in another file, adjust the file path:
grep -E "(suspicious-domain.com|malicious-actor.net|threat-site.xyz)" /var/log/nginx/access.log Step 5: Correlate Domains and Timeframe
5.1: Extract and Format Relevant Results
* Combine the commands to get time-specific domain hits:
grep "2024-08-17 00:1[0-2]" /var/log/dns.log | grep -E "(suspicious-domain.com|malicious-actor.net|threat- site.xyz)"
* Sample Output:
2024-08-17 00:11:32 suspicious-domain.com accessed by 192.168.1.50
2024-08-17 00:12:01 malicious-actor.net accessed by 192.168.1.75
* Interpretation:
* The command revealswhich domain(s)were contacted during the specified time.
Step 6: Verification and Documentation
6.1: Verify Domain Matches
* Cross-check the domains in the log output against those listed in theCCOA Threat Bulletin.pdf.
* Ensure that the time matches the specified range.
6.2: Save the Results for Reporting
* Save the output to a file:
grep "2024-08-17 00:1[0-2]" /var/log/dns.log | grep -E "(suspicious-domain.com|malicious-actor.net|threat- site.xyz)" > ~/Desktop/domain_hits.txt
* Review the saved file:
cat ~/Desktop/domain_hits.txt
Step 7: Report the Findings
Final Answer:
* Domain(s) Contacted:
* suspicious-domain.com
* malicious-actor.net
* Time of Contact:
* Between 12:10 AM to 12:12 AM on August 17, 2024
* Reasoning:
* Matched thelog timestampsanddomain nameswith the threat bulletin.
Step 8: Recommendations:
* Immediate Block:
* Add the identified domains to theblockliston firewalls and intrusion detection systems.
* Monitor for Further Activity:
* Keep monitoring logs for any further connection attempts to the same domains.
* Perform IOC Scanning:
* Check hosts that communicated with these domains for possible compromise.
* Incident Report:
* Document the findings and mitigation actions in theincident response log.
