Introduction:
In an industry flooded with self-proclaimed experts, the gap between a résumé and real-world capability has never been wider. Cybersecurity hiring managers are increasingly sceptical of certifications alone, demanding verifiable proof of practical skills—bug bounties, CTF write-ups, live project repositories, and SIEM deployments. The emergence of verified profile platforms that pull data directly from HackTheBox, GitHub, HackerOne, and Credly represents a paradigm shift: your work speaks, not your claims. This article dissects how IT operations professionals can transition into Blue Team and SOC roles by building a tangible, verifiable portfolio anchored in Linux, Wazuh, and continuous hands-on practice.
Learning Objectives:
- Understand the architecture and deployment of Wazuh as an open-source SIEM for homelab and enterprise threat detection.
- Master essential Linux commands and system hardening techniques critical for SOC analysts.
- Leverage platforms like HackTheBox, DockerLabs, and GitHub to create a verifiable chain of practical cybersecurity achievements.
- Implement a step-by-step homelab SOC environment that mirrors real-world security operations centres.
- Integrate automated credential verification and portfolio building to stand out in the job market.
You Should Know:
- Building Your Verifiable Cybersecurity Arsenal: Platforms That Matter
The modern cybersecurity professional is defined not by paper certificates but by a digital footprint of verified accomplishments. Platforms like CyberProfile aggregate data from HackTheBox, DockerLabs, HackerOne, GitHub, Credly, and LinkedIn, creating a single, tamper-evident link that showcases real achievements. Wuilmer Bolívar’s profile, for instance, connects seven platforms with five verified in origin, including DockerLabs, GitHub, Hack The Box, LinkedIn, and YouTube. This approach eliminates “résumé fluff” and provides hiring managers with direct access to your CTF progress, code repositories, and vulnerability reports.
Step‑by‑step guide to building your own verified portfolio:
- Audit your existing digital footprint: List all platforms where you have activity—GitHub (code), HackTheBox (CTF machines), HackerOne (bug bounties), DockerLabs (container security labs), and Credly (badges).
- Consolidate under a single identity: Use a consistent handle (e.g.,
4k4m1m3) across all platforms to build brand recognition. - Connect accounts via aggregation services: Use CyberProfile or similar to link each platform. The system pulls data directly from the source API, ensuring real-time verification.
- Populate your profile with context: Add your current role (e.g., “IT Operations Specialist | Transitioning to Blue Team & SOC”), key tools (Linux, Wazuh), and a project like “Homelab SOC”.
- Share the link strategically: Include it in your LinkedIn “About” section, email signature, and job applications. Each click gives recruiters a live dashboard of your skills.

The Wazuh SIEM Homelab: Your Blue Team Proving Ground
Wazuh is a free, open-source security information and event management (SIEM) platform that combines XDR and SOAR capabilities. Deploying a Wazuh homelab is the single most effective way to demonstrate Blue Team readiness. It allows you to ingest logs, detect anomalies, and respond to threats in a controlled environment—exactly what SOC analysts do daily.
Step‑by‑step guide to deploying Wazuh on Ubuntu 22.04 LTS:
- Prepare the environment: Ensure your system has at least 4 GB RAM and 20 GB free disk space. Update packages:
sudo apt update && sudo apt upgrade -y
2. Install the Wazuh all-in-one deployment script:
curl -sO https://packages.wazuh.com/4.9/wazuh-install.sh sudo bash wazuh-install.sh -a
This installs the Wazuh indexer, server, and dashboard in a single node.
3. Access the dashboard: After installation, note the admin password generated. Access `https://
4. Add an agent (e.g., a Linux endpoint): On a separate machine or VM, run:
curl -s https://packages.wazuh.com/4.x/wazuh-install.sh | bash -s -- -g
Then, from the Wazuh dashboard, go to “Agents” → “Deploy new agent” and follow the prompts to copy the registration command.
5. Simulate an attack: Use `nmap` or `hydra` against your agent to generate alerts. Verify that Wazuh detects port scans, failed SSH logins, and privilege escalation attempts.
6. Create custom rules: Navigate to `/var/ossec/etc/rules/` and add a rule to alert on a specific command (e.g., sudo su -). Restart Wazuh:
sudo systemctl restart wazuh-manager
3. Linux Command-Line Fu for SOC Analysts
Proficiency in the Linux command line is non-1egotiable for any SOC role. Beyond basic navigation, analysts must parse logs, monitor processes, and investigate incidents in real time. Below are essential commands with practical security applications.
Log analysis and forensics:
– `journalctl -xe -u sshd –since “1 hour ago”` – View SSH authentication logs for the last hour.
– `grep “Failed password” /var/log/auth.log | awk ‘{print $11}’ | sort | uniq -c | sort -1r` – Identify top IPs with failed SSH attempts.
– `tail -f /var/log/syslog | grep -i “error”` – Real-time monitoring of system errors.
Process and network investigation:
– `ss -tulpn` – List all listening ports and associated processes (replaces netstat).
– `lsof -i :22` – Show which process is using port 22 (SSH).
– `ps aux –sort=-%mem | head -10` – Display top 10 memory-consuming processes.
File integrity and persistence:
– `find / -type f -perm -4000 -ls 2>/dev/null` – List all SUID binaries (potential privilege escalation vectors).
– `crontab -l` – View current user’s scheduled tasks; check `/etc/crontab` for system-wide persistence mechanisms.
- Hands-On Training: HackTheBox and DockerLabs for Continuous Learning
The transition from IT operations to security requires deliberate, daily practice. HackTheBox offers a vast library of vulnerable machines that test enumeration, exploitation, and post-exploitation skills. DockerLabs, meanwhile, provides containerised environments for practising privilege escalation and web application security in isolated settings.
Integrating labs into your learning routine:
- Set a weekly target: Complete at least one HackTheBox machine (starting with “Easy” tier) and one DockerLabs challenge.
- Document every step: Use GitHub to maintain a private (or public) repository of write-ups. Include commands, screenshots, and reasoning.
- Automate your environment: Use `docker-compose` to spin up vulnerable containers locally for rapid testing.
version: '3' services: vulnerable-app: image: vulnerables/web-dvwa ports:</li> </ol> - "8080:80"
Run `docker-compose up -d` to launch DVWA for web app pentesting.
4. Connect your progress to your verified profile: Platforms like CyberProfile automatically pull your HackTheBox rank and completed machines, displaying them as verified achievements.- API Security and Cloud Hardening: The New Frontier
As organisations migrate to cloud-1ative architectures, API security and cloud misconfigurations have become primary attack vectors. A SOC analyst must understand how to secure AWS, Azure, and GCP environments, as well as the APIs that interconnect them.
Essential API security checks (using `curl` and `jq`):
- Test for exposed endpoints: `curl -X GET https://api.example.com/v1/users -H “Authorization: Bearer
” | jq .`
– Check for rate limiting: Send repeated requests and observe if a 429 (Too Many Requests) status is returned. - Validate input sanitisation: Attempt to inject `’ OR ‘1’=’1` into query parameters and monitor for SQL errors.
Cloud hardening checklist (AWS-focused):
- Enable CloudTrail for all regions and ship logs to a central S3 bucket.
- Enforce MFA on all IAM users and delete unused access keys.
- Use Security Groups with least-privilege rules (deny all inbound by default).
- Enable VPC Flow Logs to capture network traffic metadata.
- Regularly scan S3 buckets for public access using
aws s3api get-bucket-acl --bucket <name>. -
From Homelab to Job Offer: Crafting Your Narrative
A verified profile is only as powerful as the story it tells. Wuilmer Bolívar’s profile clearly positions him as an “IT Operations Specialist | Transitioning to Blue Team & SOC” with hands-on experience in “Incident & Problem Management | Linux | Wazuh”. This is not a random list of buzzwords; it is a targeted narrative that aligns with SOC job descriptions.
How to structure your portfolio narrative:
- Headline: State your current role and your target role (e.g., “IT Ops → SOC Analyst”).
- Verified platforms: List them in order of relevance (e.g., HackTheBox for technical skills, GitHub for code, Credly for certifications).
- Project highlight: Feature your “Homelab SOC” project prominently. Describe the architecture (e.g., “Wazuh SIEM + Elastic stack + 5 agents simulating real-world telemetry”).
- Call to action: Include a link to your profile and a clear statement like “Open to SOC Analyst roles – see my verified work below.”
What Undercode Say:
- Verification trumps certification: In a market where anyone can buy a certificate, verified activity on platforms like HackTheBox and GitHub provides immutable proof of skill. Recruiters are increasingly using these signals as primary filters.
- The homelab is your new résumé: Deploying a Wazuh SIEM, writing custom detection rules, and documenting incident response playbooks in a public repository demonstrates more competence than a decade-old CISSP.
- Consistency over intensity: Completing one CTF machine per week and writing a detailed write-up yields more long-term value than cramming for a certification exam in a month.
- Linux is the language of security: Mastery of the command line, log parsing, and system internals is the bedrock of any SOC role. Windows skills are valuable, but Linux remains the dominant OS in cloud and enterprise infrastructure.
- Your digital brand is your career insurance: A well-maintained, verifiable online presence protects you against layoffs and industry shifts. It makes you discoverable and credible, regardless of the economic climate.
Prediction:
- +1 The verified profile model will become the industry standard within 3–5 years, with major HR platforms (LinkedIn, Indeed) integrating direct API pulls from HackTheBox, GitHub, and bug bounty platforms to auto-populate candidate skills.
- +1 Wazuh and other open-source SIEMs will see exponential adoption in SMBs, creating a surge in demand for analysts who can deploy, tune, and respond from these tools—exactly the skills a homelab builds.
- +1 The line between IT operations and security will continue to blur; professionals who can bridge both (like Wuilmer Bolívar) will command premium salaries and faster career progression.
- -1 The proliferation of “verified” profiles may lead to credential inflation, where simply having a connected account becomes table stakes, and deeper, more nuanced evaluation methods (e.g., live technical interviews) will become the differentiator.
- -1 As AI-powered code assistants and automated pentesting tools become ubiquitous, the value of raw technical output may diminish, forcing professionals to differentiate through soft skills, threat intelligence analysis, and incident communication.
- -1 The reliance on third-party aggregation platforms introduces a single point of failure; if a platform ceases operations or suffers a breach, the entire verifiable identity of thousands of professionals could be compromised.
- +1 Open-source contribution (GitHub) will increasingly be weighted equally with formal education, as it provides transparent, peer-reviewed evidence of coding and problem-solving abilities.
- +1 The “Homelab SOC” will evolve from a hobbyist project to a formal credential, with universities and bootcamps incorporating it as a capstone requirement.
- +1 Companies will begin offering “verification bounties” – financial rewards for professionals who connect their real-world project repos and CTF profiles to their job applications, reducing hiring friction.
- +1 The global shortage of qualified SOC analysts will persist, but the barrier to entry will lower for those who embrace this verifiable, hands-on approach, democratising access to high-paying security roles.
