Introduction
Cybersecurity analysts and incident responders face increasingly complex threats that require sharp detection and response skills. Izzmier Izzuddin Zulkepliās “50 Hands-On Scenarios For Detection, Analysis & Response” provides a practical guide for refining threat investigation techniques. Covering SIEM, EDR, NDR, and cloud-based alerts, this resource helps analysts move beyond basic triage and develop deeper analytical judgment.
Learning Objectives
- Understand how to analyze real-world attack scenarios from multiple security tools.
- Learn MITRE ATT&CK mappings for threat classification and response.
- Develop critical thinking skills for contextual threat investigation.
You Should Know
1. SIEM Alert Triage with Splunk Query
Command:
index=security sourcetype=firewall action=blocked src_ip= dest_ip= | stats count by src_ip, dest_ip, action | sort -count
Step-by-Step Guide:
This Splunk query filters blocked firewall events, groups them by source and destination IPs, and sorts by frequency. Analysts can use this to identify repeated attack patterns, such as brute-force attempts or port scanning.
2. EDR Malware Analysis with PowerShell
Command:
Get-WinEvent -LogName "Microsoft-Windows-Sysmon/Operational" |
Where-Object {$<em>.ID -eq 1 -and $</em>.Message -like "malware"} |
Select-Object TimeCreated, Message
Step-by-Step Guide:
This PowerShell command retrieves Sysmon process creation events containing “malware” in the log message. Analysts can track malicious process executions and correlate them with other security alerts.
- NDR Threat Hunting with Zeek (Bro) Logs
Command:
cat conn.log | zeek-cut id.orig_h id.resp_h proto |
awk '$3 == "tcp" && $4 > 1000 {print $1, $2, $4}' |
sort -k3 -nr
Step-by-Step Guide:
This Zeek log analysis extracts high-volume TCP connections, helping detect potential DDoS attacks or data exfiltration attempts.
4. Cloud Security: AWS GuardDuty Findings Query
Command:
aws guardduty list-findings --detector-id d1a2b3c4d5 --finding-criteria '{"Severity": {"Gt": 6}}'
Step-by-Step Guide:
This AWS CLI command filters high-severity GuardDuty findings, allowing analysts to prioritize critical cloud threats like unauthorized API access.
5. MITRE ATT&CK Technique Mapping
Command:
import mitreattack.attack2csv as a2c
a2c.techniques_to_csv("T1059", "powershell_techniques.csv")
Step-by-Step Guide:
This Python script extracts MITRE ATT&CK technique T1059 (Command-Line Interface) into a CSV for further analysis, helping analysts map adversary behaviors.
What Undercode Say
- Key Takeaway 1: Real-world simulations bridge the gap between theoretical knowledge and practical incident response.
- Key Takeaway 2: Contextual questions during investigations lead to better threat judgment.
Analysis:
Zulkepliās approach emphasizes hands-on learning, which is critical in cybersecurity. By incorporating SIEM, EDR, and cloud logs, analysts gain a holistic view of threats. The MITRE ATT&CK integration ensures structured threat classification, while probing questions encourage deeper analysisāessential for modern SOC teams.
Prediction
As cyber threats evolve, scenario-based training will become standard in SOCs. AI-driven threat simulations and automated MITRE ATT&CK mapping tools will further enhance analyst efficiency, reducing detection and response times.
