Building a SOC Team: Essential Cybersecurity Practices and Tools

Introduction

A Security Operations Center (SOC) is critical for detecting, analyzing, and responding to cybersecurity threats. Building an effective SOC requires the right team, tools, and processes. Below, we outline key learning objectives, verified commands, and best practices for establishing a SOC.

Learning Objectives

• Understand the core components of a SOC team
• Learn essential cybersecurity commands for threat detection
• Implement best practices for SOC operations

You Should Know

1. Network Traffic Analysis with Tcpdump

Command:

tcpdump -i eth0 -w capture.pcap 

Step-by-Step Guide:

• This command captures network traffic on interface `eth0` and saves it to capture.pcap.
• Use Wireshark or Zeek to analyze the packet capture for malicious activity.
• Filter traffic with `tcpdump -i eth0 src 192.168.1.1` to isolate specific IPs.

2. Windows Event Log Analysis

Command (PowerShell):

Get-WinEvent -LogName Security -MaxEvents 50 | Format-List 

Step-by-Step Guide:

• Retrieves the last 50 security events from Windows Event Log.
• Filter for failed logins:

  Get-WinEvent -FilterHashtable @{LogName='Security'; ID=4625} 
  

• Export logs for SIEM integration.

3. SIEM Configuration for Threat Detection

Splunk Query Example:

index=security sourcetype=firewall action=blocked | stats count by src_ip 

Step-by-Step Guide:

• Configures Splunk to track blocked firewall events.
• Use `src_ip` to identify repeated attack sources.
• Set up alerts for unusual activity patterns.
  1. Endpoint Detection and Response (EDR) with Osquery

Command:

SELECT  FROM processes WHERE path LIKE '%malware%'; 

Step-by-Step Guide:

• Osquery allows SQL-like queries on endpoints.
• Monitor suspicious processes and file changes.
• Integrate with threat intelligence feeds.

5. Cloud Security Hardening (AWS CLI)

Command:

aws iam get-account-authorization-details --query 'UserDetailList[?PasswordEnabled==<code>true</code>]' 

Step-by-Step Guide:

• Lists IAM users with password logins (risk factor).
• Enforce MFA:

  aws iam enable-mfa-device --user-name Alice --serial-number arn:aws:iam::123456789012:mfa/Alice --authentication-code-1 123456 --authentication-code-2 789012 
  

6. Vulnerability Scanning with Nmap

Command:

nmap -sV --script vuln 192.168.1.0/24 

Step-by-Step Guide:

• Scans a subnet for services and vulnerabilities.
• Use `-O` for OS detection.
• Export results to XML for reporting:

  nmap -oX scan_results.xml 192.168.1.1 
  

7. Incident Response Playbook

Steps:

1. Isolate affected systems.

1. Collect logs with `dfir_ntfs` (Windows) or `dd` (Linux).

3. Analyze using Volatility (memory forensics).

4. Remediate vulnerabilities.

What Undercode Say

• Key Takeaway 1: A SOC is only as strong as its automation and threat intelligence integration.
• Key Takeaway 2: Continuous training (e.g., LetsDefend) is essential for SOC analysts.

Analysis:

The rise of AI-powered attacks demands adaptive SOC strategies. Organizations must invest in real-time monitoring, automated response tools, and cross-trained personnel. The next generation of cybersecurity professionals (like the young analyst mentioned in the LinkedIn post) will drive innovation in threat hunting and mitigation.

Prediction

By 2026, SOC teams will increasingly rely on AI-driven threat detection, reducing response times from hours to seconds. However, adversarial AI will also escalate, creating an arms race in cybersecurity.
