Security principles are vital concepts from "summary" of Official (ISC)2 Guide to the CISSP CBK by Adam Gordon
Security principles are the foundation upon which effective security programs are built. These principles serve as the guiding framework for designing, implementing, and managing security controls within an organization. By understanding and applying these principles, security professionals can ensure that their organization's assets are protected from potential threats and vulnerabilities. One of the key security principles is the principle of least privilege, which states that individuals should only be given the minimum level of access necessary to perform their job functions. This principle helps to reduce the risk of unauthorized access and limits the potential damage that can be caused by malicious insiders. Another important security principle is defense in depth, which involves implementing multiple layers of security controls to protect against a variety of threats. This approach recognizes that no single security measure is foolproof and that it is important to have redundancies in place to mitigate the risk of a security breach. Additionally, the principle of separation of duties is crucial for ensuring accountability and preventing fraud within an organization. By dividing responsibilities among multiple individuals, organizations can reduce the risk of collusion and ensure that no single individual has unchecked power over critical systems or information. Furthermore, the principle of security by design emphasizes the importance of incorporating security considerations into the design and development of systems and applications from the outset. By integrating security into every stage of the development lifecycle, organizations can proactively identify and address potential security issues before they become serious threats.- Security principles play a vital role in shaping the way organizations approach security and risk management. By adhering to these principles, security professionals can help to create a strong security posture that protects their organization's valuable assets and information from potential security threats.
