Why is security a non functional requirement?

Is security a functional or non-functional requirement?

Nonfunctional Requirements (NFRs) define system attributes such as security, reliability, performance, maintainability, scalability, and usability. They serve as constraints or restrictions on the design of the system across the different backlogs.

Is security a quality requirement or functional requirement?

Non-Functional Requirement (NFR) specifies the quality attribute of a software system. They judge the software system based on Responsiveness, Usability, Security, Portability and other non-functional standards that are critical to the success of the software system.

Is an example of non-functional security requirements?

Non-Functional Security Requirements

Examples: The software must remain resilient in the face of attacks. The behavior of the software must be correct and predictable. The software must be available and behave reliably even under DOS attacks.

Which software security requirements is non-functional?

Non-Functional Requirements are the constraints or the requirements imposed on the system. They specify the quality attribute of the software. Non-Functional Requirements deal with issues like scalability, maintainability, performance, portability, security, reliability, and many more.

What are security requirements?

What is NFRs non-functional requirements and why it is important in the software engineering?

If you think of functional requirements as those that define what a system is supposed to do, non functional requirements (NFRs) define constraints which affect how the system should do it. While a system can still work if NFRs are not met, it may not meet user or stakeholder expectations, or the needs of the business.
