Which security design principle states that a system should maintain a safe state after experiencing any failure?

Which security design principle states that a system should maintain a safe state after experiencing any failure?

The principle of fail-safe defaults states that, unless a subject is given explicit access to an object, it should be denied access to that object. This principle requires that the default access to an object is none.

Which security design principle states that the security mechanisms should be as simple and small as possible?

The principle of economy of mechanism states that security mechanisms should be as simple as possible. If a design and implementation are simple, fewer possibilities exist for errors.

Which security design principle states that accept decision should be based on permission rather than exclusion?

Fail-safe defaults Fail-safe defaults means that access decisions should be based on permission rather than exclusion.

Which design principles of security states that unless the subject is given explicit access to the object it should be denied access to that object?

Principe of Fail Safe Defaults: This principle states that unless the subject is given explicit access to the object it should be denied access to that object. This means that the default access to object is none.

What are the key principles of security?

The fundamental principles (tenets) of information security are confidentiality, integrity, and availability. Every element of an information security program (and every security control put in place by an entity) should be designed to achieve one or more of these principles. Together, they are called the CIA Triad.

What are key principles of security?

The Principles of Security can be classified as follows:

• Confidentiality: The degree of confidentiality determines the secrecy of the information.
• Authentication: Authentication is the mechanism to identify the user or system or the entity.
• Integrity:
• Non-Repudiation:
• Access control:
• Availability:

What is the principle of fail-safe defaults?

Definition 13-2. The Principle of Fail-Safe Defaults states that, unless a subject is given explicit access to an object, it should be denied access to that object. This principle requires that the default access to an object is none.

What are the three security design principles?

Security principles

• Minimise attack surface area.
• Establish secure defaults.
• The principle of Least privilege.
• The principle of Defence in depth.
• Fail securely.
• Don’t trust services.
• Separation of duties.
• Avoid security by obscurity.

What is the principle of open design in security?

The principle of open design states that the security of a mechanism should not depend on the secrecy of its design or implementation. Designers and implementers of a program must not depend on secrecy of the details of their design and implementation to ensure security.

What should be the design of a security system?

The protection system’s design should be simple and small as possible. In their words, “techniques such as line-by-line inspection of software and physical examination of hardware that implements protection mechanisms are necessary. For such techniques to be successful, a small and simple design is essential.”

What are the design principles of Secure Computing?

The principles of secure design discussed in this section express common-sense applications of simplicity and restriction in terms of computing. We will discuss detailed applications of these principles throughout the remainder of Part 5, and in Part 8, “Practicum.”

What is the principle of psychological acceptability in security?

The principle of psychological acceptability states that security mechanisms should not make the resource more difficult to access than if the security mechanisms were not present. Configuring and executing a program should be as easy and as intuitive as possible, and any output should be clear, direct, and useful.
