Week 1: Build the Foundation of Cybersecurity Basics (Days 1–7)
Day 1–2: How the Internet Really Works
Let’s start at square one: IP addresses, DNS, packets, HTTP vs HTTPS, TCP/IP.
What to watch:
- “How the Internet Works” by PowerCert Animated Videos (YouTube, about 20 minutes)
- Professor Messer’s Network+ N10-009 series (YouTube, episodes 1–10)
Goal: Explain without sweating how your phone talks to a website.
Day 3–4: See What You’re Up Against
Check out the OWASP Top 10 (2024–2025) and take a beginner’s look at the MITRE ATT&CK Framework.
Helpful stuff:
- TryHackMe’s “Intro to Offensive Security” and “OWASP Top 10” rooms (free tier)
- Web Security Academy by PortSwigger (free labs)
Goal: Know the 10 most common ways hackers break into websites and apps.
Day 5–7: Make Your Own Hacking Playground
Never test skills on real systems—use a safe lab. Here’s how:
- Download VirtualBox or UTM (free)
- Set up Kali Linux and Windows 10/11 VMs
- Add Metasploitable 2 and DVWA (both intentionally vulnerable)
- Install Burp Suite Community and Wireshark
By Day 7, you’ll have a sandbox where you can break things safely.
Week 2: Defense First — Become Unbreakable (Days 8–14)
Day 8–10: Passwords & Authentication as Components of Cybersecurity Basics
- Start using a password manager (Bitwarden is free forever)
- Turn on 2FA everywhere you can—switch to passkeys if possible
- Learn the difference: passkeys, TOTP, WebAuthn
Real task: Audit your accounts and fix any weak spots.
Day 11–13: Lock Down Your Devices
- Full-disk encryption (BitLocker or FileVault)
- Set up firewall rules: Little Snitch (Mac) or SimpleWall (Windows)
- Try DNS-level blocking: NextDNS or ControlD (free options)
- Turn on automatic updates, don’t skip them
- For your phone: GrapheneOS or stock iOS with Lockdown Mode
Goal: Make your devices tougher to hack than most people’s.
Day 14: Outsmart Phishing & Social Engineering
Spend a day on real phishing tests:
- Run your own campaigns with GoPhish (watch a tutorial first)
- TryHackMe’s “Phishing” room
- Practice spotting fake login pages on OpenPhish’s live feed
After this, clicking sketchy links won’t be a problem.
Week 3: Master Cybersecurity Basics by Thinking Like an Attacker (Days 15–22)
Day 15–17: Recon & OSINT
Find out how attackers collect info before striking:
- Play with Maltego Community Edition
- Try the Harvester, Amass, and Shodan
- Use Google Dorks and the OSINT Framework
Challenge: Do a full OSINT search on yourself. See what’s out there—then clean it up.
Day 18–20: Dive into Web Application Attacks
Fire up your lab and try:
- SQL injection (SQLi-Labs or DVWA)
- Cross-Site Scripting (XSS)
- File inclusion bugs
- Broken authentication
Tools: Burp Suite Community
Platform: TryHackMe “Web Fundamentals” to “OWASP Top 10” path (all free)
Day 21–22: Network Attacks & Wi-Fi Security
- Analyze packets with Wireshark
- Learn ARP spoofing and MITM basics (Bettercap or Ettercap)
- Crack your own Wi-Fi (WPA2/3) with Aircrack-ng
- Try an evil twin attack
Goal: Understand why public Wi-Fi is risky and how to protect yourself.
Week 4: Tools, Careers & Long-Term Defense (Days 23–30)
Day 23–25: Essential Tools, One by One
Work through these each day:
- Nmap (network scanning)
- Metasploit (exploitation framework)
- John the Ripper or Hashcat (password cracking)
- Ghidra or x64dbg (dipping your toes into reverse engineering)
For hands-on practice, check out HackTheBox Academy (free) and TryHackMe’s “Complete Beginner” path.
Day 26–27: Incident Response & Logging
Things go sideways sometimes. Here’s how to handle it:
- Dig into Windows Event Logs and Sysmon
- Get a feel for the ELK Stack, or check out Wazuh if you want a free SIEM
- Set up a simple home SOC using Security Onion
Now, get your hands dirty and spin up a ransomware attack in your lab. Then jump in and respond, just like you would on the job.
Day 28–29: Pick Your Path & Build Your Portfolio
Time to figure out where you want to go next:
- If you’re drawn to defense (blue team), look at CompTIA Security+ or eJPT
- Want to play offense (red team)? eCPPT or OSCP are your tracks
- Interested in governance and risk? Learn the basics of NIST CSF and ISO 27001
Start putting your work somewhere visible, a GitHub repo or a Notion page works great. This becomes your living résumé.
Day 30: Final Challenge & Cert Prep
Pick one of these free capstone challenges and finish strong:
- TryHackMe “Intro to Cyber Security” full path certificate
- HackTheBox Starting Point track
- Google Cybersecurity Professional Certificate (audit it for free on Coursera)
Once you’re done, take a second to celebrate. You now know about 80% of what junior analysts bring on their first day.
Free or Low-Cost Resources You’ll Actually Use to Master Cybersecurity Basics
