Session 2 Study Guide: The Digital Shield & Cyber Hygiene
“A Guardian who cannot protect themselves cannot protect the community.”
1. Core Concept: The Digital Shield
In the physical world, a Man O' War comrade understands perimeter security. In the digital world, your perimeter is your data. Cyber Hygiene is the practice of maintaining "clean" and secure habits to prevent zero-day attacks, phishing, and data leaks.
- The Goal: To move from being "digitally vulnerable" to becoming a hardened target.
- The Vanguard Rule: Security is not a product you buy; it is a habit you practice.
2. The Three Pillars of Cyber Defense
- Identity Security: Ensuring only you can access your accounts.
- Device Hardening: Closing the "digital windows" on your phone and laptop.
- Human Intelligence (HUMINT): Developing a "BS Detector" for scams and social engineering.
3. Hands-On Tactical Activities
Activity A: The Password Strength Test
Most people use passwords that an AI can crack in less than 3 seconds.
- The Task: Test your current password strength (don't use your actual sensitive password, use a similar variation).
- Tool: Kaspersky Password Check or Security.org How Secure is My Password
- Goal: Create a "Passphrase" (a sentence with symbols) that would take 100+ years to crack.
Activity B: 2FA (Two-Factor Authentication) Drill
2FA is your second line of defense. Even if someone steals your password, they can't get in without your physical phone.
- The Task: Enable 2FA on your primary WhatsApp and Email accounts.

Activity C: Phishing Identification (The Spot the Scam Challenge)
Scammers use "Social Engineering" to trick your brain.
- The Task: Take the Google Phishing Quiz to see if you can be fooled by a fake email.

4. The Vanguard "Security Scrub" Checklist
Complete these five steps before Session 3:
- [ ] Check for Breaches: Go to Have I Been Pwned and enter your email to see if your data was leaked in the past.
- [ ] App Permissions: Go to your phone settings and delete any app you haven't used in 3 months.
- [ ] Update Everything: Install any pending OS or App updates (these often contain "Security Patches").
- [ ] Clear the Cache: Clear your browser history and cookies to remove tracking tokens.
- [ ] Set a Privacy Screen: Ensure your phone requires a PIN/Biometric to open (no "Swipe to Unlock").
5. Session 2 Assignment
Identify one "Digital Vulnerability" in your local command or community. Example: "The Unit's duty roster is posted on a public notice board where anyone can see phone numbers."
Be prepared to discuss a "Digital Fix" for this in the WhatsApp group.
Vanguard Note: “Discipline in the field is useless if you are compromised in the cloud.”
