* 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.
NEW QUESTION # 92
Which of the following should occur FIRST during the vulnerability identification phase?
- A. Determine the categories of vulnerabilities possible for the type of asset being tested.
- B. Run vulnerability scans of all in-scope assets.
- C. Assess the risks associated with the vulnerabilities Identified.
- D. Inform relevant stakeholders that vulnerability scanning will be taking place.
Answer: D
Explanation:
During thevulnerability identification phase, thefirst stepis toinform relevant stakeholdersabout the upcoming scanning activities:
* Minimizing Disruptions:Prevents stakeholders from mistaking scanning activities for an attack.
* Change Management:Ensures that scanning aligns with operational schedules to minimize downtime.
* Stakeholder Awareness:Helps IT and security teams prepare for the scanning process and manage alerts.
* Authorization:Confirms that all involved parties are aware and have approved the scanning.
Incorrect Options:
* B. Run vulnerability scans:Should only be done after proper notification.
* C. Determine vulnerability categories:Done as part of planning, not the initial step.
* D. Assess risks of identified vulnerabilities:Occurs after the scan results are obtained.
