Principles of Cybersecurity Reference Guide

Cybersecurity principles within the realm of information technology are a crucial set of practices aimed at safeguarding corporate infrastructures. These principles encompass system, data, internal, external, and physical security, collectively working to thwart unauthorized access and alterations within corporate environments. A profound understanding of these principles is pivotal for crafting robust, organization-specific security policies.

Principles

Separation (of domains/duties)

This principle involves segregating different domains or duties to limit access and thwart unauthorized actions. By enforcing separation, organizations ensure that users or systems only have access to resources necessary for their specific tasks, thereby minimizing the risk of unauthorized access or compromise (Stallings & Brown, 2017).

Isolation

Isolation entails keeping different components of a system or network separate to contain potential security breaches and limit the impact of an attack. This principle prevents the spread of malware or unauthorized activities, enabling the implementation of network segmentation and isolation techniques for enhanced overall security (Wang & Ledley, 2012).

Encapsulation

The encapsulation principle revolves around protecting data by encapsulating it within defined boundaries or structures, limiting direct access. This enhances data integrity and confidentiality by restricting direct manipulation and supports the implementation of secure coding practices and data encryption techniques (Hentea, 2021).

Modularity

The modularity principle focuses on designing a system with independent, interchangeable modules to facilitate easier maintenance and reduce the impact of a security breach. It reduces system complexity, making it easier to identify and mitigate vulnerabilities. Modularity supports secure coding practices and the implementation of modular security measures (Mirza et al., 2016).

Simplicity of Design (economy of mechanism)

Keeping security mechanisms simple to minimize potential vulnerabilities and increase reliability is the essence of this principle. The simplicity of design reduces the likelihood of errors or oversights that could lead to security vulnerabilities, supporting the implementation of straightforward and effective security measures (Whitman & Mattord, 2018).

Minimization of Implementation (least common mechanism)

This principle involves minimizing shared mechanisms to limit potential points of failure or compromise. By doing so, organizations can reduce the attack surface and limit the impact of security breaches. Minimization of implementation supports the deployment of unique and tailored security measures (Stallings & Brown, 2017).

Open Design

This design principle is about designing security mechanisms with openness and allowing their scrutiny by the security community. In this regard, open design supports transparent coding for peer review, thus enabling audits to ensure that security mechanisms are robust enough to be trusted (Rieb & Lechner, 2016).

Complete Mediation

Full mediation is another security principle that verifies all requested resource accesses so as to continue governing them. For example, this principle eliminates the chances of incomplete checks, which could lead to a situation when there is no control over accessing resources. As a result, the principle advocates for the use of comprehensive access control and auditing systems (Stallings & Brown, 2017).

Layering (Defense in Depth)

This approach entails multilevel implementation of safeguard measures in an information system. Layering enhances redundancy and protects one layer from being breached even if another one has been compromised. Consequently, it calls for a comprehensive defensive posture (Whitman & Mattord, 2018).

Least Privilege

The principle of least privilege entails providing users or systems with the minimum level of access necessary to perform their tasks. This limits potential damage from accidental or intentional misuse, reducing the attack surface. Least privilege supports the implementation of strict access controls and segregation of duties (Stallings & Brown, 2017).

Fail-Safe Defaults (Open/Secure)

Ensuring that a system defaults to a secure state in the event of an error or misconfiguration characterizes this cybersecurity principle. Fail-safe defaults minimize the risk of unauthorized access or data exposure in case of system failures, supporting the implementation of secure default configurations and fail-safe mechanisms (Mailloux, 2018).

Least Astonishment (Psychological Acceptability)

This principle involves designing security mechanisms in a way that aligns with users’ expectations and avoids surprises. This enhances user acceptance and compliance with security measures, reducing the likelihood of circumvention. Least astonishment supports user-friendly security designs and clear communication of security policies (Hentea, 2021).

Minimize Trust Surface (Reluctance to Trust)

Minimizing the number of components or interactions that need to be trusted for the system to function securely characterizes this cybersecurity principle. This limits the potential points of compromise and reduces overall risk. Minimizing trust surfaces supports the implementation of trust minimization strategies and thorough risk assessments (Stallings & Brown, 2017).

Usability

This principle ensures that security measures are user-friendly and do not hinder legitimate user activities. Usability promotes user compliance and reduces the likelihood of workarounds that could compromise security. This principle supports the implementation of effective security measures that do not overly burden users (Whitman & Mattord, 2018).

Trust Relationships

This cybersecurity principle focuses on establishing and maintaining trust only with known and verified entities. This minimizes the risk of unauthorized access or data exposure through untrusted connections and supports the implementation of secure authentication and authorization mechanisms (Kesan & Hayes, 2011).

Principles of Cybersecurity Reference Guide
Cybersecurity principles of IT focus on a set of practices intended to keep a corporate infrastructure secure. These practices include, but are not limited to, system, data, internal, external, and physical security. The principles are designed to prevent unauthorized access or alterations of a corporate environment. By understanding how cybersecurity principles are defined, they can then be used to develop a comprehensive, corporate-specific security policy.
