Essential Skills For Aspiring L1 SOC Analysts

Wanting to get ahead as an L1 SOC Analyst? If you’re 12-18 months into your career, focus heavily on becoming an SME in:
– Programming (Python, PowerShell, SQL)
– Digital Forensics
– Threat Hunting

This is the playbook to ensure you set yourself up as a weapon in Security Operations. The best thing is that you can learn these skills online – FOR FREE! For those looking to break into cyber, this also applies to you.

You Should Know:

1. Programming (Python, PowerShell, SQL):

Python: Python is a must-have skill for SOC analysts. It’s widely used for scripting, automation, and data analysis.
Example Command: `python3 -m pip install requests` (Install the requests library for HTTP requests)

Script Example: Automate log analysis with Python:

import pandas as pd
logs = pd.read_csv('security_logs.csv')
suspicious_activity = logs[logs['action'] == 'failed_login']
print(suspicious_activity)

PowerShell: Essential for Windows environments, PowerShell helps in automating tasks and managing systems.
Example Command: `Get-EventLog -LogName Security -Newest 20` (Retrieve the latest 20 security logs)

Script Example: Monitor user login attempts:

Get-EventLog -LogName Security | Where-Object {$_.EventID -eq 4625} | Format-Table -AutoSize

SQL: Understanding SQL is crucial for querying databases, which is often required in forensic investigations.
Example Command: `SELECT * FROM logs WHERE action = ‘failed_login’;` (Query for failed login attempts)

2. Digital Forensics:

Learn to use tools like Autopsy or FTK Imager for disk analysis.
Command Example: Use `dd` in Linux to create a disk image:
```
dd if=/dev/sda of=disk_image.img bs=1M
```
Analyze memory dumps with Volatility:
```
volatility -f memory_dump.img pslist
```

3. Threat Hunting:

Use tools like Splunk or ELK Stack for log analysis.
Command Example: Search for suspicious IPs in logs:
```
grep "192.168.1.100" /var/log/auth.log
```

Leverage YARA for malware hunting:
