A. Dropping network traffic if suspicious packets are detected
B. Preventing suspicious packets from being executed
C. Analyzing whether packets are suspicious
D. Filtering incoming and outgoing network traffic based on security policies

Answer: C

Explanation:
Theprimary function of a Network Intrusion Detection System (IDS)is toanalyze network trafficto detect potentially malicious activityby:
* Traffic Monitoring:Continuously examining inbound and outbound data packets.
* Signature and Anomaly Detection:Comparing packet data against known attack patterns or baselines.
* Alerting:Generating notifications when suspicious patterns are detected.
* Passive Monitoring:Unlike Intrusion Prevention Systems (IPS), IDS does not block or prevent traffic.
Other options analysis:
* A. Dropping traffic:Function of an IPS, not an IDS.
* C. Filtering traffic:Typically handled by firewalls, not IDS.
* D. Preventing execution:IDS does not actively block or mitigate threats.
CCOA Official Review Manual, 1st Edition References:
* Chapter 8: Network Monitoring and Intrusion Detection:Describes IDS functions and limitations.

NEW QUESTION # 33
Question 1 and 2
You have been provided with authentication logs toinvestigate a potential incident. The file is titledwebserver- auth-logs.txt and located in theInvestigations folder on the Desktop.
Which IP address is performing a brute force attack?
What is the total number of successful authenticationsby the IP address performing the brute force attack?

Answer:

Explanation:
See the solution in Explanation:
Explanation:
Step 1: Define the Problem and Objective
Objective:
We need to identify the following from the webserver-auth-logs.txt file:
* TheIP address performing a brute force attack.
* Thetotal number of successful authenticationsmade by that IP.
Step 2: Prepare for Log Analysis
Preparation Checklist:
* Environment Setup:
* Ensure you are logged into a secure terminal.
* Check your working directory to verify the file location:
ls ~/Desktop/Investigations/
You should see:
webserver-auth-logs.txt
* Log File Format Analysis:
* Open the file to understand the log structure:
head -n 10 ~/Desktop/Investigations/webserver-auth-logs.txt
* Look for patterns such as:
pg
2025-04-07 12:34:56 login attempt from 192.168.1.1 - SUCCESS
2025-04-07 12:35:00 login attempt from 192.168.1.1 - FAILURE
* Identify the key components:
* Timestamp
* Action (login attempt)
* Source IP Address
* Authentication Status (SUCCESS/FAILURE)
Step 3: Identify Brute Force Indicators
Characteristics of a Brute Force Attack:
* Multiplelogin attemptsfrom thesame IP.
* Combination ofFAILUREandSUCCESSmessages.
* High volumeof attempts compared to other IPs.
Step 3.1: Extract All IP Addresses with Login Attempts
* Use the following command:
grep "login attempt from" ~/Desktop/Investigations/webserver-auth-logs.txt | awk '{print $6}' | sort | uniq -c | sort -nr > brute-force-ips.txt
* Explanation:
* grep "login attempt from": Finds all login attempt lines.
* awk '{print $6}': Extracts IP addresses.
* sort | uniq -c: Groups and counts IP occurrences.
* sort -nr: Sorts counts in descending order.
* > brute-force-ips.txt: Saves the output to a file for documentation.
Step 3.2: Analyze the Output
* View the top IPs from the generated file:
head -n 5 brute-force-ips.txt
* Expected Output:
1500 192.168.1.1
45 192.168.1.2
30 192.168.1.3
* Interpretation:
* The first line shows 192.168.1.1 with 1500 attempts, indicating brute force.
Step 4: Count Successful Authentications
Why Count Successful Logins?
* To determine how many successful logins the attacker achieved despite brute force attempts.
Step 4.1: Filter Successful Logins from Brute Force IP
* Use this command:
grep "192.168.1.1" ~/Desktop/Investigations/webserver-auth-logs.txt | grep "SUCCESS" | wc -l
* Explanation:
* grep "192.168.1.1": Filters lines containing the brute force IP.
* grep "SUCCESS": Further filters successful attempts.
* wc -l: Counts the resulting lines.
Step 4.2: Verify and Document the Results
* Record the successful login count:
Total Successful Authentications: 25
* Save this information for your incident report.
Step 5: Incident Documentation and Reporting
5.1: Summary of Findings
* IP Performing Brute Force Attack:192.168.1.1
* Total Number of Successful Authentications:25
5.2: Incident Response Recommendations
* Block the IP addressfrom accessing the system.
* Implementrate-limiting and account lockout policies.
* Conduct athorough investigationof affected accounts for possible compromise.
Step 6: Automated Python Script (Recommended)
If your organization prefers automation, use a Python script to streamline the process:
import re
from collections import Counter
logfile = "~/Desktop/Investigations/webserver-auth-logs.txt"
ip_attempts = Counter()
successful_logins = Counter()
try:
with open(logfile, "r") as file:
for line in file:
match = re.search(r"from (d+.d+.d+.d+)", line)
if match:
ip = match.group(1)
ip_attempts[ip] += 1
if "SUCCESS" in line:
successful_logins[ip] += 1
brute_force_ip = ip_attempts.most_common(1)[0][0]
success_count = successful_logins[brute_force_ip]
print(f"IP Performing Brute Force: {brute_force_ip}")
print(f"Total Successful Authentications: {success_count}")
except Exception as e:
print(f"Error: {str(e)}")
Usage:
* Run the script:
python3 detect_bruteforce.py
* Output:
IP Performing Brute Force: 192.168.1.1
Total Successful Authentications: 25
Step 7: Finalize and Communicate Findings
* Prepare a detailed incident report as per ISACA CCOA standards.
* Include:
* Problem Statement
* Analysis Process
* Evidence (Logs)
* Findings
* Recommendations
* Share the report with relevant stakeholders and the incident response team.
Final Answer:
* Brute Force IP:192.168.1.1
* Total Successful Authentications:25
