Introduction:

Security Operations Center (SOC) Analysts serve as cybersecurity’s frontline defenders, identifying and neutralizing threats using advanced tools and methodologies. As demand surges in 2025, mastering core technical skills—from SIEM querying to incident response—is critical for career advancement in this evolving landscape.

Learning Objectives:

  • Execute critical SIEM, network, and endpoint analysis commands.
  • Apply MITRE ATT&CK techniques to real-world threat scenarios.
  • Automate SOC workflows using SOAR platforms and scripting.

1. SIEM Query Fundamentals

`index=security sourcetype=firewall dest_ip=”192.168.1.100″ | stats count by src_ip`

Step-by-Step Guide:

  1. Purpose: This Splunk query identifies all firewall traffic targeting internal IP 192.168.1.100, counting connections per source IP.
  2. Usage: Replace `dest_ip` with your asset’s IP. Use `stats count` to detect scanning attempts (e.g., >100 connections/minute).
  3. Analysis: High counts indicate reconnaissance; escalate to Tier 2 for investigation.

2. Network Traffic Analysis with Wireshark

`tcp.flags.syn == 1 and tcp.flags.ack == 0`

Step-by-Step Guide:

  1. Purpose: Filters SYN floods (common DDoS) in Wireshark.
  2. Usage: Apply filter > Export suspicious IPs. Correlate with SIEM logs using src_ip= 
    </code>. </li>
<li>Mitigation: Block IPs at firewall: `iptables -A INPUT -s [bash] -j DROP` (Linux). </li>
</ol>

<h2 style="color: yellow;">3. Endpoint Detection & Response (EDR)</h2>

<h2 style="color: yellow;">`SentinelOne-cli threat kill --id THREAT_ID`</h2>

<h2 style="color: yellow;">Step-by-Step Guide:</h2>

<h2 style="color: yellow;">1. Purpose: Terminates malicious processes in SentinelOne.</h2>

<ol>
<li>Usage: Retrieve `THREAT_ID` via dashboard alert. Isolate host first: <code>SentinelOne-cli isolate on</code>. </li>
<li>Forensics: Extract artifacts: <code>SentinelOne-cli threat export --id THREAT_ID --path /logs</code>. </li>
</ol>

<h2 style="color: yellow;">4. Threat Hunting with YARA</h2>

[bash]
rule APT29_Backdoor {
strings: $str = "EvilCorpLoader"
condition: $str
}

    Step-by-Step Guide:

    1. Purpose: Scans memory/files for APT29 malware signatures.

    2. Usage: Run `yara rule.yar /malware/sample.exe`.

    1. Integration: Automate scans via Cortex XSOAR playbook hourly.

    5. Windows Incident Response

    `Get-WinEvent -LogName Security -FilterXPath 'EventID=4688' | Select-Object -First 50`

    Step-by-Step Guide:

    1. Purpose: Retrieves process creation events (Event ID 4688) via PowerShell.
    2. Usage: Hunt for `cmd.exe` spawning from unexpected locations (e.g., temp folders).
    3. Triage: Export to CSV: | Export-Csv -Path C:\investigation\procs.csv.

    6. MITRE ATT&CK: Credential Dumping

    Detection Command:

    `Sysmon -EventID 10: "lsass.exe" accessed by non-LSM processes`

    Mitigation:

    1. Enable Protected Process Light for LSASS: reg add HKLM\SYSTEM\CurrentControlSet\Control\Lsa /v RunAsPPL /t REG_DWORD /d 1.

    2. Alert on `sekurlsa::logonpasswords` Mimikatz usage via SIEM.

    7. SOAR Playbook Automation

    TheHive Webhook Setup:

    import requests
url = "https://[bash]/api/alert"
headers = {"Authorization": "Bearer [bash]"}
data = {"title": "Phishing Alert", "description": "Malicious attachment detected"}
response = requests.post(url, json=data, headers=headers)

    Step-by-Step Guide:

    1. Purpose: Auto-create cases in TheHive from email gateway alerts.
    2. Usage: Trigger via Python script when Splunk detects attachment.hash=[bash].

    3. Enrichment: Auto-pull threat intel from VirusTotal API.

    What Undercode Say:

    • Demand vs. Skill Gap: 60% of SOC roles require Python/PowerShell proficiency—prioritize scripting over entry-level certs.
    • Shift Realities: SOAR reduces alert fatigue by 40%; invest in automation literacy.
    • Career Trajectory: Tier 2 analysts with threat-hunting skills command 35% higher salaries.
    • Hybrid Advantage: Cloud-native EDR/XDR adoption enables global "follow-the-sun" SOC models.

    Analysis:

    The SOC role is evolving from alert triage to proactive threat hunting. Mastery of EDR APIs (e.g., SentinelOne), SOAR integrations, and ATT&CK mapping separates top candidates. While Security+ remains foundational, OSCP/GCTI holders accelerate to Tier 3. Employers increasingly value automation scripts over manual analysis—Python is non-negotiable. Remote work expands access but intensifies competition; specialize in cloud (AWS/Azure) security to dominate 2025–2026 hiring cycles. Shift work persists, yet AI-augmented tools like XSOAR are reducing burnout by automating 70% of Tier 1 tasks.
