Security in Custom Apps: SOC 2, GDPR, and Best Practices 2025

10 min read

TL;DR(Too Long; Didn't Read)

Custom apps require: encryption at rest and in transit, authentication/authorization, regular security audits, SOC 2 compliance (for B2B SaaS), and GDPR compliance (for EU users). Security should be built-in from day one, not added later. Professional development includes security by default.

Security is critical for custom applications. Learn SOC 2 compliance, GDPR requirements, security best practices, and common vulnerabilities.

Security Requirements

Encryption: At rest (AES-256) and in transit (TLS 1.3). Protect sensitive data, user information, and API keys.

Authentication: OAuth 2.0, JWT tokens, multi-factor authentication, secure password storage (bcrypt, Argon2).

Authorization: Role-based access control (RBAC), principle of least privilege, API rate limiting, input validation.

Compliance Requirements

SOC 2 Type II: Security, availability, processing integrity, confidentiality, privacy. Annual audits required for B2B SaaS.

GDPR: Data protection for EU users, right to access/deletion, data portability, privacy by design, consent management.

HIPAA: Healthcare data protection, encryption requirements, access controls, audit logs, business associate agreements.

Security Best Practices

Input Validation: Validate and sanitize all inputs, use parameterized queries, prevent SQL injection, XSS protection.

Security Headers: Content-Security-Policy (CSP), Strict-Transport-Security (HSTS), X-Frame-Options, X-Content-Type-Options.

Regular Audits: Security audits quarterly, penetration testing annually, dependency scanning, vulnerability assessments.

Common Vulnerabilities

OWASP Top 10: Injection, broken authentication, sensitive data exposure, XML external entities, broken access control, security misconfiguration, XSS, insecure deserialization, using components with known vulnerabilities, insufficient logging.

Prevention: Input validation, secure authentication, encryption, proper access controls, security headers, regular updates.

Security by Default

Built-In: Security should be built-in from day one, not added later. Professional development includes security by default.

Cost: Adding security later costs 3-5x more than building it in initially. Security breaches cost millions.

Professional Development

Includes: Security from day one, SOC 2 compliance (Scale tier), GDPR compliance, regular security audits, penetration testing, security monitoring.
