Cybersecurity Architecture: Principles

Cybersecurity Architecture Principles

The presentation highlights key cybersecurity architecture principles aimed at enhancing system security and resilience. It emphasizes the **Defense in Depth** approach, which involves implementing multiple layers of protection, such as multi-factor authentication (MFA), firewalls, encryption, and endpoint detection, to prevent reliance on a single point of failure. The **Principle of Least Privilege** is another critical concept, ensuring that access is granted only to users with a demonstrated need and that access rights are regularly audited and revoked when no longer necessary. Additionally, the **Separation of Duties** principle promotes distributing responsibilities to prevent single points of control, requiring collaboration among multiple actors for critical operations, such as requester-approver roles in access control. The concept of **Secure by Design** underscores the importance of integrating security at every stage of the system lifecycle, from design to deployment, with continuous testing to maintain security. Lastly, the presentation warns against relying on **Security by Obscurity** and advocates for transparency and well-tested algorithms, such as AES and RSA, to build robust systems resistant to vulnerabilities.
