Best Practices for Application Security

  • As part of the “Best Practices” series by Uplatz

 

Welcome to another essential installment of the Uplatz Best Practices series — securing the foundation of your digital business.
 Today’s focus: Application Security — protecting applications from threats across the SDLC (Software Development Lifecycle).

🧱 What is Application Security?

Application Security involves identifying, fixing, and preventing vulnerabilities in application code, configurations, APIs, and deployment environments.

It spans:

  • Secure coding practices

  • Threat modeling

  • Authentication and authorization

  • Input validation

  • Dependency management

  • Runtime protection

✅ Best Practices for Application Security

Building secure applications means shifting left, automating protection, and instilling security into every line of code. Here’s how:

1. Shift Security Left

🔁 Integrate Security in Dev from Day One
 🧪 Run Static Analysis (SAST) Early in CI/CD
 🛠 Use Pre-commit Hooks for Secret Scanning

2. Follow Secure Coding Standards

📘 Adopt OWASP Top 10 and CWE Guidelines
 🔐 Validate All Inputs — Never Trust the Client
 🔒 Avoid Using Hardcoded Secrets or Tokens

3. Use Strong Authentication & Authorization

🔑 Implement Multi-Factor Authentication (MFA)
 🛂 Use Role-Based Access Control (RBAC)
 🔁 Apply Principle of Least Privilege in APIs and UIs

4. Secure Third-Party Dependencies

📦 Use Dependency Scanners (e.g., Snyk, OWASP Dependency-Check)
 📅 Update Libraries Regularly
 ⚠️ Avoid Abandoned or Unmaintained Packages

5. Protect Against Injection Attacks

🚫 Use Prepared Statements for SQL Queries
 🔍 Sanitize and Validate Inputs on Server Side
 🧪 Test for Command Injection, XSS, CSRF, etc.

6. Secure API Endpoints

🔐 Use API Keys, OAuth2, or JWT for Auth
 📏 Rate Limit and Throttle Endpoints
 📜 Document APIs Clearly and Keep Private APIs Hidden

7. Encrypt Data Everywhere

🔒 Use TLS 1.2+ for All Data in Transit
 🗄 Encrypt Sensitive Fields in Databases
 🔐 Rotate Encryption Keys Periodically

8. Log and Monitor for Security Events

📋 Log Auth Failures, Input Errors, Access Patterns
 📊 Use SIEM Tools or Cloud Monitoring (e.g., Datadog, Splunk)
 🔔 Set Alerts for Suspicious Activity

9. Perform Regular Security Testing

🧪 Use Dynamic Application Security Testing (DAST)
 🏹 Conduct Penetration Testing at Least Quarterly
 🧰 Simulate Attacks Using Bug Bounty Platforms or Red Teams

10. Keep Secrets Out of Code

🚫 Never Store Secrets in Git, Docker Images, or Logs
 🔐 Use Secret Managers (e.g., HashiCorp Vault, AWS Secrets Manager)
 🔁 Rotate Keys and Tokens Frequently

💡 Bonus Tip by Uplatz

The cost of a vulnerability multiplies as it moves down the SDLC.
 Empower your dev teams with tools, knowledge, and ownership of security.
