engineering process of a system. But there is no clear criterion for satisfying
the soft goals of a system. Nonfunctional requirements framework helps in identifying
the objectives for which the system is being achieved. Soft goal Interdependency
Graph is usually used for the modeling of conditional attributes of any specific
system. Using nonfunctional requirements framework, quality attributes of the
system can be decomposed into sub-goals.
Question:
You have been studied about Non Functional Requirements (NFR) Framework in lecture slides.
Based on knowledge about NFR framework, you are required to
draw Soft goal Interdependency Graph (SIG) for Security.
Note: You must have to represent soft goal refinements
(AND/OR) and soft goal contributions (positive/negative)
in Software Independency Graph (SIG) if necessary.
Possible soft goals of the system under consideration are:
Security
- Integrity
- Accuracy
- Availability
Integrity
- Confidentiality
- Minimize redundancy
Confidentiality
- Use of passwords
- Minimize external communication
Availability
- Recoverability
- Extra Testing
Recoverability
- Backup
```
