Is data security a non-functional requirement?
Operational requirements describe how well the system is performing. When we refer to operational requirements within non-functional requirements, we are talking about accessibility, confidentiality, integrity, safety, usability, security, availability, efficiency, reliability, and suitability.
Is security a quality requirement or functional requirement?
Types of security requirements
Just like performance requirements define what a system has to do and be to perform according to specifications, security requirements define what a system has to do and be to perform securely. … So functional security requirements describe functional behavior that enforces security.
Is robustness a functional requirement?
An important aspect of quality for a high-quality system is the ability to function correctly and in an expected manner independent of events in the environment. This ability is also known as robustness.
What are non functional security requirements?
The non-functional security requirements specify a security quality or attribute that the software must possess. The security property requirements specify the properties that software must exhibit. … The software must remain resilient in the face of attacks. The behavior of the software must be correct and predictable.
Which one is a functional requirement?
Functional requirements define the basic system behaviour. Essentially, they are what the system does or must not do, and can be thought of in terms of how the system responds to inputs. Functional requirements usually define if/then behaviours and include calculations, data input, and business processes.
What is scalability in non-functional requirements?
Scalability is the ability of the application to handle an increase in workload without performance degradion, or its ability to quickly enlarge.
