Software Security

Secure Development Lifecycle (SDLC)

Design Phase

• Threat Modeling: Systematic threat analysis for new features
• Security Architecture Review: Review of security architecture
• Privacy by Design: Privacy as a fundamental principle from the start
• Attack Surface Analysis: Minimization of attack surface

Development Phase

• Secure Coding Standards: Established programming guidelines according to OWASP
• Code Reviews: Peer review with focus on security
• Static Application Security Testing (SAST): Automated code analysis
• Dependency Scanning: Verification of libraries and frameworks

Testing Phase

• Dynamic Application Security Testing (DAST): Runtime security tests
• Interactive Application Security Testing (IAST): Combined testing approaches
• Penetration Testing: Regular manual security tests
• Security Regression Testing: Tests for every code change

Deployment Phase

• Infrastructure as Code (IaC) Security: Secure infrastructure configuration
• Container Security Scanning: Verification of container images
• Configuration Management: Secure default configurations
• Secrets Management: Secure management of API keys and passwords

Vulnerability Management

Automated Scans

• SAST Integration: Code analysis in the CI/CD pipeline
• Dependency Checks: Continuous checking for known CVEs
• Container Scanning: Analysis of Docker images before deployment
• Infrastructure Scanning: Regular review of infrastructure configuration

Severity Assessment according to CVSS

We use the Common Vulnerability Scoring System (CVSS) 3.1:

Assessment Criteria

• Attack Vector: Network, adjacent, local, physical
• Attack Complexity: Low or high
• Required Privileges: None, low, high
• User Interaction: Required or not required
• Scope: Unchanged or changed
• Impact: Confidentiality, integrity, availability

Patch Management

• Emergency Patches: Critical security updates within 24h
• Regular Updates: Planned security updates every 2 weeks
• Zero-Day Response: Immediate response to unknown threats
• Rollback Procedures: Safe rollback of faulty updates

Code Security

Input Validation

• Parameter Validation: Verification of all input parameters
• SQL Injection Prevention: Prepared statements and ORM
• XSS Protection: Output encoding and Content Security Policy
• Command Injection Prevention: Secure system calls
• File Upload Security: Validation and sandboxing of uploads

Authentication & Authorization

• Multi-Factor Authentication (MFA): Two-factor authentication
• OAuth 2.0 / OpenID Connect: Standardized authentication
• Role-Based Access Control (RBAC): Role-based permissions
• Least Privilege Principle: Minimal required permissions
• JWT Security: Secure implementation of JSON Web Tokens

Session Management

• Secure Session Tokens: Cryptographically strong session IDs
• Session Timeout: Automatic logout after inactivity
• Session Fixation Protection: Protection against session hijacking
• Cross-Site Request Forgery (CSRF) Protection: Token-based protection
• Secure Cookie Handling: HttpOnly, Secure, SameSite flags

Data Protection

• Data Classification: Categorization of sensitive data
• Encryption Standards: AES-256 for sensitive data
• Key Rotation: Regular rotation of encryption keys
• Data Loss Prevention (DLP): Protection against data leaks
• Field-Level Encryption: Encryption at field level

Third-Party Security

Dependency Management

• Software Bill of Materials (SBOM): Complete listing of all dependencies
• Vulnerability Databases: Integration of CVE and NVD
• License Compliance: Verification of license compatibility
• Update Monitoring: Automatic notification of available updates
• Dependency Pinning: Fixed versions for critical dependencies

Supply Chain Security

• Vendor Security Assessment: Assessment of third-party security
• Code Signing: Verification of software integrity
• Private Repositories: Internal mirrors for external packages
• Integrity Checks: Checksums and digital signatures
• Build Reproducibility: Verifiable build processes

API Security

Design Principles

• Secure by Default: Secure default configurations
• Principle of Least Privilege: Minimal API permissions
• Defense in Depth: Multi-layered security
• Fail Securely: Secure error handling

Implementation

• Rate Limiting: Protection against API abuse
• Input Validation: Strict validation of all API parameters
• Output Encoding: Secure data return
• Error Handling: No sensitive information in error messages
• Logging: Complete logging of API calls

Security Testing

Automated Tests

• Unit Security Tests: Security tests at code level
• Integration Security Tests: Tests of component interaction
• API Security Tests: Special tests for API endpoints
• UI Security Tests: Frontend security tests

Manual Tests

• Code Reviews: Manual review of critical code parts
• Penetration Testing: External security tests
• Security Architecture Reviews: Review of overall architecture
• Threat Modeling Workshops: Collaborative threat analysis

Security Training
