Cybersecurity Essentials for Developers

Security Best Practices Encryption

Warning Cyber attacks cost businesses $4.35 million on average in 2022 (IBM Report). Don't become a statistic.

1. Password Management

Stop using "password123":

Use passphrases (correct-horse-battery-staple)
Enable 2FA everywhere possible
Consider a password manager (Bitwarden, 1Password)

Password Don'ts

Reuse passwords across sites
Store credentials in plaintext
Use personal info (birthdates, pet names)

2. Secure Coding Practices

Common vulnerabilities to eliminate:

Injection attacks
Broken Authentication
Sensitive Data Exposure
XML External Entities (XXE)
Broken Access Control
Security Misconfiguration
Cross-Site Scripting (XSS)
Insecure Deserialization
Using Components with Known Vulnerabilities
Insufficient Logging & Monitoring

3. Encryption Fundamentals

Always implement:

TLS 1.2+ for all communications
End-to-end encryption for sensitive data
Proper key management — never hardcode keys
