Cybersecurity is a vast field with numerous domains, each requiring specialized skills and expertise. This article explores key cybersecurity roles, their responsibilities, and practical commands and tools used in each domain.

You Should Know:

1. Security Operations Center (SOC) Analyst

  • Monitors security alerts and investigates incidents.
  • Uses SIEM tools like Splunk, ELK Stack, or Azure Sentinel.

Commands & Tools:

 Check active network connections (Linux) 
netstat -tulnp

Analyze logs with grep 
grep "Failed password" /var/log/auth.log

Splunk query for failed logins 
index=linux sourcetype=syslog "Failed password"

2. Red Teaming / Penetration Testing

  • Simulates cyberattacks to identify vulnerabilities.

Commands & Tools:

 Nmap scan for open ports 
nmap -sV -A target.com

Metasploit exploit example 
msfconsole 
use exploit/windows/smb/ms17_010_eternalblue 
set RHOSTS 192.168.1.1 
exploit

Password cracking with John the Ripper 
john --wordlist=/usr/share/wordlists/rockyou.txt hashes.txt

3. Governance, Risk, and Compliance (GRC)

  • Ensures adherence to security policies (ISO 27001, NIST).

Commands & Tools:

 Check open ports (Compliance check) 
ss -tuln

Audit file permissions 
find / -type f -perm /o=w -exec ls -la {} \;

Lynis system audit 
lynis audit system

4. Identity and Access Management (IAM)

  • Manages user permissions and authentication.

Commands & Tools:

 List all users (Linux) 
cat /etc/passwd

Check sudo privileges 
sudo -l

Active Directory user enumeration (Windows) 
net user /domain

5. Cloud Security

  • Secures AWS, Azure, and GCP environments.

Commands & Tools:

 Check misconfigured S3 buckets (AWS CLI) 
aws s3 ls 
aws s3api get-bucket-acl --bucket my-bucket

Azure security scan 
az security task list

GCP IAM permissions check 
gcloud projects get-iam-policy my-project

6. Security Research & Threat Intelligence

  • Analyzes malware and emerging threats.

Commands & Tools:

 Analyze a suspicious file with strings 
strings malware.exe

Check file hashes (SHA-256) 
sha256sum suspicious_file

VirusTotal API scan 
curl --request POST --url 'https://www.virustotal.com/vtapi/v2/file/scan' --form 'apikey=YOUR_API_KEY' --form '[email protected]'

What Undercode Say:

Cybersecurity is not just about hacking—it’s about defense, governance, and risk management. Each role contributes uniquely to securing digital assets. Whether you’re into offensive security, compliance, or cloud defense, mastering these commands will enhance your efficiency.

Prediction:

As cyber threats evolve, demand for specialized roles like AI Security Engineers and Quantum Cryptography Experts will rise. Continuous learning and hands-on practice remain key.

Expected Output:

A structured breakdown of cybersecurity domains with actionable commands for each role.
