Introduction:
In the rapidly evolving landscape of cybersecurity, the role of the Security Operations Center (SOC) Analyst is often misunderstood, with many fearing automation renders it obsolete. However, the reality is that the modern SOC demands a fusion of deep technical acumen, structured frameworks like MITRE ATT&CK, and continuous skill development. The curated materials from industry veteran Izzmier Izzuddin Zulkepli—including specialized eBooks, MITRE playbooks, and comprehensive PDF compilations—provide a roadmap for mastering these competencies, bridging the gap between theoretical knowledge and real-world incident response.
Learning Objectives:
- Master the core competencies of a modern SOC Analyst, including advanced investigation techniques and career progression strategies.
- Learn to operationalize the MITRE ATT&CK framework for effective threat detection, hunting, and incident response.
- Acquire practical, hands-on skills through Linux/Windows command-line tools, log analysis, and security tool configuration.

The content highlighted in the post, particularly the “
SOC Analyst Is Not Dead – Guide To SOC Skills, Investigations And Career Progression," emphasizes that a successful analyst must possess a blend of networking, operating system internals, and security tool expertise. To complement the theoretical frameworks from the eBooks, one must master foundational command-line tools for log analysis and system investigation. On Linux, analysts often start with `journalctl` to parse systemd logs. A common investigation command is: [bash] sudo journalctl -xe -u sshd --since "2025-03-25 00:00:00" --until "2025-03-26 00:00:00"
This filters SSH daemon logs within a specific timeframe, crucial for detecting brute-force attempts. For process lineage, `pstree -p` reveals parent-child process relationships, which is vital for identifying malicious process injection.
On Windows, PowerShell is the analyst’s swiss-army knife. To quickly extract security event logs related to failed logins (Event ID 4625), use:
Get-WinEvent -FilterHashtable @{LogName='Security'; ID=4625; StartTime=(Get-Date).AddDays(-1)} | Select-Object -First 20 TimeCreated, Message
For persistent threat hunting, using `Sysmon` (System Monitor) is recommended. A typical Sysmon configuration logs process creation (Event ID 1) with full command lines. Analyzing these with `wevtutil` or `Get-WinEvent` allows analysts to spot suspicious parent-child relationships, such as `cmd.exe` spawning `powershell.exe` with encoded commands.
Step-by-Step: Setting Up a Basic Lab Environment
- Install VirtualBox or VMware to create isolated Windows and Linux VMs.
- Deploy a SIEM like Splunk Free or Wazuh (open-source) to centralize logs.
- Configure Sysmon on Windows using SwiftOnSecurity’s configuration file:
Sysmon64.exe -accepteula -i sysmon-config.xml. - Forward logs to the SIEM using Universal Forwarder (Splunk) or an agent (Wazuh).
- Simulate an attack using tools like `Atomic Red Team` to generate test alerts, allowing you to practice the investigation techniques described in the eBook.

Operationalizing the MITRE ATT&CK Playbook for SOC Investigations
The “MITRE ATT&CK Playbook For SOC Investigation & Response” is a critical resource. It translates the high-level ATT&CK matrix into actionable playbooks. For example, if an alert triggers for T1059.001 (Command and Scripting Interpreter: PowerShell), the playbook should guide the analyst through a specific sequence.
Step-by-Step: Investigating T1059.001 with PowerShell Logging
- Enable Script Block Logging: On Windows, set the Group Policy or registry to enable PowerShell Script Block Logging (Event ID 4104). This captures the actual PowerShell code executed, not just the command line.
Set-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Windows\PowerShell\ScriptBlockLogging" -Name "EnableScriptBlockLogging" -Value 1
- Query for Encoded Commands: Attackers often use `-EncodedCommand` to obfuscate. Use this `wevtutil` command to quickly identify them:
wevtutil qe Microsoft-Windows-PowerShell/Operational /rd:true /f:text /e:true /c:10 /q:"[EventData[Data[@Name='CommandInvocation']='-EncodedCommand']]"
- Correlate with Process Creation: Cross-reference the decoded command lines with Sysmon Event ID 1 to see what processes were spawned. For instance, if the decoded command includes
Invoke-Mimikatz, you’d immediately classify it as credential dumping (T1003). - Containment: According to the playbook, if the process is malicious and active, containment steps include isolating the host via EDR console or using `Restart-Service` in PowerShell to stop a malicious service, while preserving evidence with a memory dump.

Building a Career with Certified Expertise and Hands-On Content
The post mentions a remarkable achievement of 57 certifications in cybersecurity, forensics, programming, and electronics. This highlights a path for professionals: supplement formal certifications with practical, creator-driven content. The “LinkedIn Cybersecurity Document By Izzmier” compilation serves as a knowledge base for exam preparation and on-the-job reference.
To emulate this career trajectory, one should integrate continuous learning with practical lab work. For instance, while studying for the CompTIA Security+ or CySA+, use the PDF documents to review concepts and then immediately apply them in a home lab. For network analysis, tools like `tcpdump` (Linux) and `Wireshark` are indispensable. A typical command to capture traffic on a specific port without DNS resolution is:
sudo tcpdump -i eth0 -nn -s0 -w capture.pcap port 443
Analyzing this capture in Wireshark, as detailed in the analysis PDFs, helps in understanding encrypted traffic patterns and identifying anomalies like unexpected certificate issuers or TLS version mismatches.
4. Automation and AI in the SOC
The inclusion of “AI Engineering” in the creator’s profile underscores the future of cybersecurity. Analysts are now expected to leverage AI for log analysis and automation. For example, using Python to parse massive log files with libraries like `pandas` is a modern requirement. A simple script to detect high-frequency failed SSH attempts from a `/var/log/auth.log` would be:
import re
from collections import Counter
failed_pattern = re.compile(r'Failed password for . from ([\d.]+) port')
with open('/var/log/auth.log', 'r') as f:
lines = f.readlines()
ip_list = [failed_pattern.search(line).group(1) for line in lines if failed_pattern.search(line)]
for ip, count in Counter(ip_list).items():
if count > 10:
print(f'Potential brute-force from {ip} with {count} attempts')
This script, combined with the structured investigation processes from the eBooks, demonstrates how an analyst can move from manual review to automated, intelligent threat hunting.
What Undercode Say:
- Structured Learning is Key: The combination of eBooks, MITRE playbooks, and up-to-date PDF compilations provides a structured path from foundational knowledge to advanced SOC operations, proving that the SOC analyst role is evolving, not dying.
- Practical Application is Non-Negotiable: Real expertise is forged in labs and command lines. The resources highlighted encourage a shift from passive reading to active, hands-on skill development, which is essential for effective incident response and career growth in cybersecurity.
The curated content from Izzmier Izzuddin Zulkepli represents a modern approach to cybersecurity education—one that integrates structured frameworks (MITRE ATT&CK) with practical, immediately applicable resources. For professionals navigating the noise of the cybersecurity field, such targeted materials offer a direct path to acquiring the skills that SOC teams desperately need. The future of the SOC lies in automation and AI, but the core skill of an analyst—the ability to investigate, adapt, and think critically—remains irreplaceable and is best cultivated through resources that emphasize both theory and relentless practice.
