🔒 Secure Design Principles: A Thread
Least privilege: Limit access rights to only what's necessary for users/programs to perform their tasks. This reduces the potential impact of security breaches.
Complete mediation, aka non-bypassability: Ensure every access to resources is checked for authorization, preventing unauthorized actions even if attackers bypass initial security measures.
Economy of mechanism, aka simplicity: Keep the design simple to minimize the risk of errors or vulnerabilities. Complex systems are harder to secure and easier to exploit.
Open design: Avoid security through obscurity. Instead, rely on openly scrutinized designs that can withstand public scrutiny and peer review.
Fail-safe defaults: Set secure defaults for systems and applications, ensuring they operate safely even when users or configurations are compromised.
Separation of privilege: Employ multiple layers of defense, such as two-factor authentication, to prevent a single compromise from granting unrestricted access.
Least common mechanism: minimize shared resources among users to limit the potential impact of security breaches and prevent unauthorized access.
Psychological acceptability: design security measures that are user-friendly and intuitive, encouraging compliance and reducing the likelihood of circumvention.
By incorporating these principles into design practices, organizations can build robust and resilient systems that withstand evolving cybersecurity threats. #SecureDesign #Cybersecurity 💡🔐
