The CIA Triad — The Foundation of Cybersecurity:

1. Confidentiality
   - Keep data secret from unauthorized people
   - Example: Encryption, passwords, access control

2. Integrity
   - Ensure data is accurate and unchanged
   - Example: Checksums, digital signatures

3. Availability
   - Ensure data is accessible when needed
   - Example: Backup, disaster recovery

Real-World Example:
Your bank account should be:
- Confidential (only you can see it)
- Intact (no one can change your balance)
- Available (you can access it anytime)

Types of Cybersecurity:

1. Network Security
   - Protecting computer networks from intruders
   - Firewalls, VPNs, IDS/IPS

2. Application Security
   - Secure software from vulnerabilities
   - Code reviews, penetration testing

3. Information Security
   - Protecting data at rest and in transit
   - Encryption, access control

4. Cloud Security
   - Protecting cloud-based systems
   - AWS/Azure/GCP security

5. Endpoint Security
   - Securing devices like laptops, phones
   - Antivirus, patch management

6. Disaster Recovery
   - Planning for worst-case scenarios
   - Backups, incident response

How to Spot a Phishing Email:

1. Check the sender's email address
   - Often slightly different from legitimate
   - Example: support@amaz0n.com vs amazon.com

2. Look for urgent language
   - "Your account will be closed!" 
   - "Immediate action required!"

3. Check for poor grammar and spelling
   - Professional companies don't make these mistakes

4. Hover over links (don't click!)
   - See where they actually lead

5. Never share personal information
   - Banks never ask for passwords via email

The 3-2-1 Backup Rule:

3 Copies of Your Data
- Original + 2 backups

2 Different Storage Types
- External hard drive + cloud
- USB + NAS

1 Offsite Backup
- Keep one backup in a different location
- Protect against fire, theft, ransomware

Examples:
- Copy 1: Your computer
- Copy 2: External hard drive
- Copy 3: Cloud storage (Google Drive, OneDrive)

Automate Your Backups!
- Set it and forget it
- Test your backups regularly
