350-401 Exam - Question 523


Which design principle states that a user has no access by default to any resource, and unless a resource is explicitly granted, it should be denied?

Show Answer
Correct Answer: B

The principle that states a user has no access by default to any resource, and unless a resource is explicitly granted, it should be denied, is called 'fail-safe defaults.' This design principle ensures that the default action is to deny access, reinforcing security by requiring explicit permission for access. The 'least privilege' principle, on the other hand, refers to granting the minimum necessary permissions to a user for completing their tasks, but it does not inherently imply an access-denied default state.

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

Fail safe defaults is a design philosophy where IF any device or process or system fails for whatsoever reason it will DEFAULT TO SAFE outcome. Principle of Least Privilege means applying a zero trust mindset and providing ONLY the required access that people need to do their jobs and nothing else.

Clearly stated in below url The principle of least privilege states that a subject should be given only those privileges that it needs in order to complete its task. 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. https://www.informit.com/articles/article.aspx?p=30487&seqNum=2

While both A and B appear correct, the key words in the question seem to more closely match option B 'fail safe defaults' according to the CISA website https://www.cisa.gov/uscert/bsi/articles/knowledge/principles/failing-securely https://www.cisa.gov/uscert/bsi/articles/knowledge/principles/least-privilege

Wrong, The Principle of Least Privilege means that ALL access to denied UNLESS it is needed. Your answer is completely wrong.

https://medium.com/strike-sh/rest-security-design-principles-434bd6ee57ea Fail-Safe Defaults A user’s default access level to any resource in the system should be “denied” unless they have been granted a “permit” explicitly.

It's A by far. The principle of least privilege is about restricting access rights to the minimum necessary, while fail-safe defaults is about ensuring that a system defaults to a secure state in the face of errors or unexpected conditions.
