Introduction:
A Security Operations Center (SOC) Analyst does more than stare at dashboards—they dissect attacker behavior, correlate logs across disparate systems, and orchestrate incident response. This roadmap transforms foundational networking knowledge into proactive threat hunting, leveraging MITRE ATT&CK, SIEM queries, and attack simulations within a self-built home lab.
Learning Objectives:
– Build a fully functional SOC home lab using Wazuh, Sysmon, and Splunk Free to generate and investigate realistic attacks.
– Write advanced SIEM queries (KQL, SPL) to detect lateral movement, credential access, and persistence mechanisms.
– Apply the Cyber Kill Chain to triage alerts, create custom detection rules, and perform Tier 2 threat hunting.
You Should Know:
1. Foundation Lab: Windows + Linux Telemetry Pipeline
Start by simulating a small corporate environment. A SOC analyst must see how endpoints generate logs and how a SIEM centralizes them.
Step‑by‑step guide:
1. Set up VMs (VirtualBox or VMware):
– Ubuntu 22.04 (SIEM server + Wazuh manager)
– Windows 10/11 (target endpoint)
– Kali Linux (attack simulator)
2. Install Wazuh on Ubuntu:
curl -sO https://packages.wazuh.com/4.7/wazuh-install.sh && sudo bash wazuh-install.sh -a
Access Wazuh dashboard at `https://
3. Deploy Sysmon on Windows (download from Microsoft):
Download Sysmon and configuration (SwiftOnSecurity’s config) Invoke-WebRequest -Uri "https://raw.githubusercontent.com/SwiftOnSecurity/sysmon-config/master/sysmonconfig-export.xml" -OutFile sysmonconfig.xml .\Sysmon64.exe -accepteula -i sysmonconfig.xml
4. Install Wazuh agent on Windows and Linux, pointing to the Ubuntu server’s IP. Verify telemetry: run `netstat -an` on Windows → check Wazuh dashboard for `EventID 5156` (network connection).
2. SIEM Log Analysis: Splunk & KQL Queries for Credential Attacks
You cannot detect what you cannot query. Focus on failed logins, unusual process trees, and LSASS access.
Step‑by‑step guide:
1. Download Splunk Free (500 MB/day) and ingest Windows Event Logs (Security, Sysmon).
2. Detect brute‑force (Kerberos/ NTLM) with SPL:
index=windows sourcetype="WinEventLog:Security" EventCode=4625 | stats count by Account_Name, Source_Network_Address, _time span=5m | where count > 10
3. For Microsoft Sentinel (Azure free tier), use KQL to find LSASS process access:
SecurityEvent | where EventID == 4663 | where ObjectType == "Process" | where ObjectName contains "lsass.exe" | extend AccessMask = tostring(Properties) | where AccessMask contains "0x1010" // PROCESS_VM_READ + PROCESS_QUERY_INFORMATION
4. Correlate with network logs: `index=firewall dest_port=445 action=allowed` (SMB lateral movement). Practice by generating a failed login via `net use \\target\IPC$ /user:fake pass`.
3. Simulate Real Attacks Using Atomic Red Team & Caldera
Understanding attacker TTPs (Techniques, Tactics, Procedures) makes triage faster. Use open‑source simulation tools.
Step‑by‑step guide:
1. Install Atomic Red Team on Windows (PowerShell as Admin):
Install-Module -1ame AtomicRedTeam -Force Import-Module "C:\AtomicRedTeam\atomics\AtomicRedTeam.psd1" Invoke-AtomicTest T1003.001 -TestNames "Dump LSASS.exe using MiniDumpWriteDump" Credential dumping
2. On Linux (Kali), simulate privilege escalation via SUID abuse:
find / -perm -4000 2>/dev/null List SUID binaries cp /bin/bash /tmp/suidbash && chmod 4755 /tmp/suidbash Create malicious SUID /tmp/suidbash -p Spawns privileged shell
3. Deploy MITRE Caldera (Ubuntu) to automate adversarial emulation:
git clone https://github.com/mitre/caldera.git && cd caldera pip install -r requirements.txt && python server.py --insecure
Access `http://localhost:8888`, create an agent on Windows, run “Discovery” and “Credential Access” profiles. Investigate the generated logs in Wazuh/Splunk.
4. Windows Event Log Deep Dive: PowerShell Filtering & Event Tracing
A Tier 1 SOC analyst must answer “Malicious, suspicious, or normal?” within seconds. Learn to filter event IDs rapidly.
Step‑by‑step guide:
1. Use Get-WinEvent to hunt for PowerShell script block logging (EventID 4104):
Get-WinEvent -FilterHashtable @{LogName='Microsoft-Windows-PowerShell/Operational'; ID=4104} |
Where-Object {$_.Message -match "DownloadString|Invoke-Expression|Base64"}
2. Detect service persistence (Windows Event ID 7045 – new service):
Get-WinEvent -FilterHashtable @{LogName='System'; ID=7045} | Select-Object TimeCreated, Message
3. On Linux, monitor `auth.log` for SSH key extraction:
sudo tail -f /var/log/auth.log | grep "Failed password" Real‑time brute force
grep "Accepted publickey" /var/log/auth.log | awk '{print $9,$11}' List successful keys
4. Create a detection rule: if a new service (7045) points to `%temp%` or `Users\Public`, flag as high severity.
5. Detection Engineering: Sigma Rules & YARA for Malware Indicators
Move from reactive alerts to proactive detections. Write Sigma rules (convert to Splunk/Sentinel) and YARA signatures.
Step‑by‑step guide:
1. Write a Sigma rule for credential dumping via `lsass.exe` memory access:
title: LSASS Access via Mimikatz status: experimental logsource: product: windows service: sysmon detection: selection: EventID: 10 TargetImage: '\lsass.exe' GrantedAccess: '0x1010' Read control condition: selection
Convert to Splunk using `sigmac` tool.
2. Create a YARA rule to detect reverse shell payloads:
rule reverse_shell_cmd {
strings:
$s1 = "System.Net.Sockets.TCPClient" nocase
$s2 = "$client.GetStream()" nocase
$s3 = "cmd.exe" nocase
condition: all of them
}
Test on a captured PowerShell reverse shell script: `yara64 reverse_shell_cmd.yar ./suspicious.ps1`.
3. Deploy YARA in Wazuh (add to `/var/ossec/etc/rules/local_rules.xml`) to alert on malware memory patterns.
6. Threat Hunting with MITRE ATT&CK Navigator
Proactively search for “living off the land” binaries (LOLBins) and abnormal process chains.
Step‑by‑step guide:
1. Map your data sources to MITRE ATT&CK. For Windows, focus on `Process` (Sysmon EID 1), `File` (EID 11), `Network Connection` (EID 3).
2. Hunt for T1218.011 (Rundll32 execution of suspicious DLL):
index=windows sourcetype="WinEventLog:Sysmon" EventID=1 | search Image="\\rundll32.exe" CommandLine=".dll," | lookup suspicious_dlls.csv dll_name OUTPUT description
3. Linux persistence via crontab (T1053.003): on Wazuh, query:
SELECT FROM syscheck WHERE path LIKE '/var/spool/cron/%' AND event_type='added';
4. Create a threat hunting dashboard listing top 5 unpatched CVEs in your lab (using OpenVAS or Lynis) and correlate with exploit attempts.
7. Incident Response Playbook: Triage to Containment
When an alert is confirmed, speed matters. Build a playbook for ransomware or data exfiltration.
Step‑by‑step guide:
1. Immediate triage – check for encryption extensions (`.encrypted`, `.lockbit`):
Get-ChildItem -Path C:\Users -Recurse -Include .encrypted -ErrorAction SilentlyContinue
2. Containment – isolate the host via Windows Firewall (or cloud security group):
New-1etFirewallRule -DisplayName "BLOCK-ALL-OUT" -Direction Outbound -Action Block -Profile Any
3. Collect forensic artifacts using KAPE or CyLR:
Linux – capture memory sudo dd if=/dev/mem of=/tmp/memory.dump bs=1M Windows – prefetch files copy C:\Windows\Prefetch\ \\network_share\case_001\
4. Write an incident report including: timeline (extracted from SIEM), affected assets, MITRE TTPs, and lessons learned. Use `csv` logs to generate Sankey diagrams of lateral movement.
What Undercode Say:
– Key Takeaway 1: A SOC analyst’s superpower is not memorizing alerts but building a repeatable investigation workflow—starting with a home lab that generates real telemetry, then mastering log queries before touching advanced threat hunting.
– Key Takeaway 2: The MITRE ATT&CK framework is your battle map; map every simulated attack (e.g., LSASS dump, cron persistence) to a technique ID, and create detection rules that fire on the behavior, not just the tool name.
Analysis: Michael Eru’s roadmap correctly emphasizes that Tier 1 excellence (knowing what “normal” looks like) unlocks Tier 2/3 skills. Most aspirants rush to threat hunting without being able to explain why a 4624 (successful logon) followed by a 4672 (special privileges) in under 2 seconds could be a pass‑the‑hash attack. The missing piece in many trainings is hands‑on log fatigue—this blueprint fixes that with concrete SIEM queries and attack simulations. Additionally, integrating Wazuh + Sysmon creates a production‑grade pipeline that scales to cloud environments. The 6‑month timeline is aggressive but feasible if the learner dedicates 15 hours/week to building and breaking their lab.
Expected Output:
(Not required as per final response, but the above constitutes the complete article.)
Prediction:
– +1 By 2027, entry‑level SOC roles will require proven lab portfolios (GitHub repos with detection rules and incident reports) instead of certifications alone—this roadmap directly addresses that shift.
– -1 Over‑automation of Tier 1 triage by AI (e.g., Microsoft Security Copilot) may reduce the number of junior analyst positions, pushing newcomers to master Tier 2 hunting and detection engineering faster than ever.
– +1 Open‑source SIEMs like Wazuh and Sigma rules will become the standard for mid‑size enterprises, democratizing advanced threat detection and reducing vendor lock‑in.
– -1 Failure to include cloud log sources (AWS CloudTrail, Azure AD sign‑ins) in home labs will leave analysts unprepared for hybrid attacks, as on‑premise only training is increasingly obsolete.
