Information Security in App Development: What Cannot Be Missing

Every app carries valuable data. And where there is value, there is risk.

Information security in development is not an add-on, but an essential pillar in building any software. Neglecting it can lead to failures, data leaks, reputational damage and even legal penalties (such as those provided for in LGPD).

In this post, we will show the key points that cannot be missing in an app that takes security seriously — from the code to the cloud.

1. Strong Authentication

Encrypted, secure passwords
Two-factor authentication (2FA or MFA)
Tokens and sessions with controlled expiration
🧠 Security starts at the front door.

2. Encryption of Sensitive Data

Encryption in transit (TLS/HTTPS)
Encryption at rest (data in the database)
Secure storage of personal, banking and business information
🔒 No sensitive data should be exposed — not even internally.

3. Secure, Reviewed Code

Input validation (to prevent SQLi, XSS, etc.)
Use of up-to-date libraries
Private repositories and versioning with history
Security must be in the code’s DNA.

4. Well-Configured Environments

Protected environment variables
Separation between dev, staging and production environments
Log monitoring and auditing
The infrastructure must be shielded too.

5. Good Practices and Security Culture

A team aware of threats and responsibilities
Applying frameworks such as OWASP, SDL and LGPD
Continuous updates and fixes
🔄 Security is not a stage — it is a constant cycle.

💡 With Pluritech, security comes from the first byte.

Our development process includes security reviews, data protection by default, and delivery with technical and legal responsibility.

Does your app protect what matters?
