ISACA Certified Cybersecurity Operations Analyst Sample Questions (Q112-Q117):

NEW QUESTION # 112
The enterprise is reviewing its security posture byreviewing unencrypted web traffic in the SIEM.
How many unique IPs have received well knownunencrypted web connections from the beginning of2022 to the end of 2023 (Absolute)?

Answer:

Explanation:
See the solution in Explanation.
Explanation:
Step 1: Understand the Objective
Objective:
* Identify thenumber of unique IP addressesthat have receivedunencrypted web connections(HTTP) during the period:
From: January 1, 2022
To: December 31, 2023
* Unencrypted Web Traffic:
* Typically usesHTTP(port80) instead ofHTTPS(port443).
Step 2: Prepare the Environment
2.1: Access the SIEM System
* Login Details:
* URL:https://10.10.55.2
* Username:ccoatest@isaca.org
* Password:Security-Analyst!
* Access via web browser:
firefox https://10.10.55.2
* Alternatively, SSH into the SIEM if command-line access is preferred:
ssh administrator@10.10.55.2
* Password: Security-Analyst!
Step 3: Locate Web Traffic Logs
3.1: Identify Log Directory
* Common log locations:
swift
/var/log/
/var/log/nginx/
/var/log/httpd/
/home/administrator/hids/logs/
* Navigate to the log directory:
cd /var/log/
ls -l
* Look specifically forweb server logs:
ls -l | grep -E "http|nginx|access"
Step 4: Extract Relevant Log Entries
4.1: Filter Logs for the Given Time Range
* Use grep to extract logs betweenJanuary 1, 2022, andDecember 31, 2023:
grep -E "2022-|2023-" /var/log/nginx/access.log
* If logs are rotated, use:
zgrep -E "2022-|2023-" /var/log/nginx/access.log.*
* Explanation:
* grep -E: Uses extended regex to match both years.
* zgrep: Handles compressed log files.
4.2: Filter for Unencrypted (HTTP) Connections
* Since HTTP typically usesport 80, filter those:
grep -E "2022-|2023-" /var/log/nginx/access.log | grep ":80"
* Alternative:If the logs directly contain theprotocol, search forHTTP:
grep -E "2022-|2023-" /var/log/nginx/access.log | grep "http"
* To save results:
grep -E "2022-|2023-" /var/log/nginx/access.log | grep ":80" > ~/Desktop/http_connections.txt Step 5: Extract Unique IP Addresses
5.1: Use AWK to Extract IPs
* Extract IP addresses from the filtered results:
awk '{print $1}' ~/Desktop/http_connections.txt | sort | uniq > ~/Desktop/unique_ips.txt
* Explanation:
* awk '{print $1}': Assumes the IP is thefirst fieldin the log.
* sort | uniq: Filters out duplicate IP addresses.
5.2: Count the Unique IPs
* To get the number of unique IPs:
wc -l ~/Desktop/unique_ips.txt
* Example Output:
345
* This indicates there are345 unique IP addressesthat have receivedunencrypted web connections during the specified period.
Step 6: Cross-Verification and Reporting
6.1: Verification
* Double-check the output:
cat ~/Desktop/unique_ips.txt
* Ensure the list does not containinternal IP ranges(like 192.168.x.x, 10.x.x.x, or 172.16.x.x).
* Filter out internal IPs if needed:
grep -v -E "192.168.|10.|172.16." ~/Desktop/unique_ips.txt > ~/Desktop/external_ips.txt wc -l ~/Desktop/external_ips.txt
6.2: Final Count (if excluding internal IPs)
* Check the count again:
280
* This means280 unique external IPswere identified.
Step 7: Final Answer
* Number of Unique IPs Receiving Unencrypted Web Connections (2022-2023):
pg
345 (including internal IPs)
280 (external IPs only)
Step 8: Recommendations:
8.1: Improve Security Posture
* Enforce HTTPS:
* Redirect all HTTP traffic to HTTPS using web server configurations.
* Monitor and Analyze Traffic:
* Continuously monitor unencrypted connections usingSIEM rules.
* Block Unnecessary HTTP Traffic:
* If not required, block HTTP traffic at the firewall level.
* Upgrade to Secure Protocols:
* Ensure all web services support TLS.

 

NEW QUESTION # 113
Which of the following is the MOST effective approach for tracking vulnerabilities in an organization's systems and applications?

• A. Rely on employees to report any vulnerabilities they encounter.
• B. Walt for external security researchers to report vulnerabilities
• C. Track only those vulnerabilities that have been publicly disclosed.
• 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.
CCOA Official Review Manual, 1st Edition References:
* Chapter 6: Vulnerability Management:Emphasizes continuous scanning as a critical part of risk mitigation.
* Chapter 9: Security Monitoring Practices:Discusses automated scanning and vulnerability tracking.

 

NEW QUESTION # 114
Which of the following is a security feature provided by the WS-Security extension in the Simple Object Access Protocol (SOAP)?

• A. Transport Layer Security (TLS)
• B. MaIware protection
• C. Message confidentiality
• D. Session management

Answer: C

Explanation:
TheWS-Securityextension inSimple Object Access Protocol (SOAP)provides security features at the message levelrather than thetransport level. One of its primary features ismessage confidentiality.
* Message Confidentiality:Achieved by encrypting SOAP messages using XML Encryption. This ensures that even if a message is intercepted, its content remains unreadable.
* Additional Features:Also provides message integrity (using digital signatures) and authentication.
* Use Case:Suitable for scenarios where messages pass through multiple intermediaries, as security is preserved across hops.
Incorrect Options:
* A. Transport Layer Security (TLS):Secures the transport layer, not the SOAP message itself.
* C. Malware protection:Not related to WS-Security.
* D. Session management:SOAP itself is stateless and does not handle session management.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 7, Section "Web Services Security," Subsection "WS-Security in SOAP" - WS-Security provides message-level security, including confidentiality and integrity.

 

NEW QUESTION # 115
An organization's financial data was compromised and posted online. The forensics review confirms proper access rights and encryption of the database at the host site. A lack of which of the following controls MOST likely caused the exposure?

• A. Multi-factor authentication (MFA)
• B. Continual backups
• C. Encryption o' data in transit
• D. Properly configured firewall

Answer: A

Explanation:
The compromise occurred despiteencryption and proper access rights, indicating that the attacker likely gained access through compromised credentials.MFAwould mitigate this by:
* Adding a Layer of Security:Even if credentials are stolen, the attacker would also need the second factor (e.g., OTP).
* Account Compromise Prevention:Prevents unauthorized access even if username and password are known.
* Insufficient Authentication:The absence of MFA often leaves systems vulnerable to credential-based attacks.
Other options analysis:
* A. Continual backups:Addresses data loss, not unauthorized access.
* C. Encryption in transit:Encryption was already implemented.
* D. Configured firewall:Helps with network security, not authentication.
CCOA Official Review Manual, 1st Edition References:
* Chapter 7: Access Management and Authentication:Discusses the critical role of MFA in preventing unauthorized access.
* Chapter 9: Identity and Access Control:Highlights how MFA reduces the risk of data exposure.
