🛡️ Cybersecurity Practices for Software

🛡️ Cybersecurity Practices for Software Engineers – Deep Dive

🔹 1. Why Cybersecurity Matters

Software engineers ka responsibility hai ki wo secure software develop kare.
Cybersecurity lapses ke consequences:

• Data breaches & leaks

• Financial losses

• Reputation damage

• Legal & compliance issues

🔹 2. Core Practices for Software Engineers

1️⃣ Secure Coding

• Input validation to prevent SQL Injection, XSS

• Avoid hardcoding secrets or passwords

• Proper authentication & authorization

2️⃣ Encryption

• HTTPS / TLS for data in transit

• Encrypt sensitive data at rest (AES, RSA)

• Password hashing (bcrypt, Argon2)

3️⃣ Regular Security Testing

• Static Application Security Testing (SAST)

• Dynamic Application Security Testing (DAST)

• Penetration testing & vulnerability scanning

4️⃣ Dependency & Package Management

• Keep third-party libraries updated

• Monitor for known vulnerabilities (CVEs)

• Use trusted sources for packages

5️⃣ Access Control & Identity Management

• Role-Based Access Control (RBAC)

• Principle of Least Privilege (PoLP)

• Multi-Factor Authentication (MFA)

6️⃣ Logging & Monitoring

• Continuous monitoring for anomalies

• Real-time alerting for suspicious activities

• Auditing for compliance

7️⃣ Incident Response

• Have a plan for breaches & vulnerabilities

• Quick containment, analysis, and patching

🔹 4. Best Practices

• Always follow secure development lifecycle (SDLC)

• Automate security testing where possible

• Educate team on latest vulnerabilities & threats

• Apply defense-in-depth approach (multiple layers of security)
