- Phishing success rate: 3-4% of employees click
Essential Security Practices
Password Security:
Strong passwords:
- 12+ characters
- Mix of uppercase, lowercase, numbers, symbols
- Unique for each account
- Changed regularly
Password managers:

Adds extra security layer:
- Something you know (password)
- Something you have (phone, security key)
- Something you are (fingerprint)
Types:
- SMS codes
- Authenticator apps (Google Authenticator, Authy)
- Security keys (YubiKey)
- Biometric (fingerprint, face)
Phishing Prevention:
Red flags:
- Urgent action required
- Suspicious sender
- Unusual requests
- Generic greetings
- Spelling errors
- Suspicious links
Protection:
✓ Verify sender email
✓ Hover over links before clicking
✓ Check for HTTPS
✓ Don't download unexpected attachments
✓ Use email filters
✓ Report suspicious emails
Software Updates:
Why important:
- Patches security vulnerabilities
- Fixes bugs
- Improves performance
Best practices:
✓ Enable automatic updates
✓ Update all software regularly
✓ Update operating system
✓ Update browser
✓ Update plugins
Network Security:
Home network:
- Change default router password
- Enable WPA3 encryption
- Disable WPS
- Hide SSID (optional)
- Use VPN for public WiFi
Public WiFi:
- Avoid sensitive transactions
- Use VPN
- Disable auto-connect
- Turn off file sharing

- External hard drive
- NAS (Network Attached Storage)
- Automated backup software
Antivirus and Firewalls:
Antivirus:
- Scans for malware
- Real-time protection
- Quarantines threats
- Examples: Windows Defender, Norton, McAfee
Firewalls:

- Blocks unauthorized access
- Hardware and software
- Built into Windows/Mac
Social Engineering Protection:
Be skeptical of:
- Unsolicited calls
- Requests for personal info
- Too-good-to-be-true offers
- Urgent requests
- Authority figures
Best practices:
✓ Verify requests independently
✓ Don't share personal info
