Personal Security

Why It Matters

Whether you're a cybersecurity student, enthusiast, or pro-in-training, you are a target. Why?

• You’re learning sensitive skills
• You may work with or study real-world systems
• You likely have access to security tools or environments
  That’s why personal security is your first line of defense.

Digital Hygiene 101

1. Use Strong, Unique Passwords

• Use a password manager like Bitwarden or 1Password
• Avoid using the same password across platforms
• Change passwords after a data breach

2. Always Use Two-Factor Authentication (2FA)

• Especially for emails, GitHub, cloud platforms, and school/work portals
• Use an authenticator app, not just SMS

3. Practice Safe Browsing

• Don’t install random browser extensions
• Avoid pirated software (malware heaven)
• Use HTTPS websites only

4. Be Careful with What You Download

• Double-check files from GitHub, Discord, or forums
• Scan anything suspicious with VirusTotal
• Use sandbox environments (like virtual machines) for testing tools

Secure Your Devices

1. Harden Your Operating System

• Use tools like Windows Hardening Scripts, AppArmor (Linux), or Little Snitch (Mac)
• Keep all systems up to date
• Disable unnecessary services and ports

2. Full-Disk Encryption

• Turn on BitLocker (Windows), FileVault (Mac), or LUKS (Linux)
• Prevents data theft if your laptop gets lost or stolen

3. Use a VPN (When Necessary)

• Encrypts your internet traffic on public Wi-Fi
• Don't use shady free VPNs—stick to trusted names (Mullvad, ProtonVPN, etc.)

What If Something Goes Wrong?

• Change passwords immediately
• Revoke sessions from any suspicious devices
• Run antivirus + malware scan
• Freeze credit or file a report if your identity is compromised
