Secure by Design / Secure by Default

Secure by Design and Secure by Default are security approaches that involve considering security requirements during the design phase of systems, products, or services. This ensures that security features are built in from the beginning rather than added as an afterthought.

Key Characteristics

• Proactive Security: Security is considered from the beginning
• Built-in Protection: Security features are inherent to the system
• Default Security: Systems are secure without additional configuration
• Integrated Approach: Security is part of the overall design process

Advantages

• Cost Efficiency: Less expensive than adding security later
• Better Integration: Security features are better integrated
• Reduced Vulnerabilities: Fewer security flaws in the final product
• Compliance: Easier to meet security regulations

Disadvantages

• Design Complexity: More complex initial design process
• Development Time: May require more time in initial phases
• Expertise Required: Requires security expertise during design
• Cost Upfront: Higher initial investment in security

Best Practices

• Include security experts in design teams
• Implement security requirements early in development
• Use security frameworks and standards
• Regular security reviews during development

Use Cases

• Software development lifecycle integration
• Cloud infrastructure design
• IoT device security
• Application security architecture
