 JOT: Journal of Object Technology - Requirements Engineering
Requirements engineering is the activity consisting of the cohesive collection of all tasks that are primarily related to an endeavor’s requirements.
Requirements analysis is the task during which elicited and reused requirements for the application, component, or center are studied, modeled, refined, prioritized, scheduled, and traced.
Requirements specification is the task during which requirements, requirement diagrams, and requirements models for the application, component, or center are documented in requirements specifications and related documents.

 System Quality Requirements Engineering
Other studies have shown that reworking requirements defects on most software development projects costs 40 to 50 percent of total project effort, and the percentage of defects originating during requirements engineering is estimated at more than 50 percent.
Often the security requirements are developed independently of the rest of the requirements engineering activity, and hence are not integrated into the mainstream of the requirements activities.
Following this work, the requirements engineering team determines the best method for eliciting initial security requirements from stakeholders, which is dependent on several factors, including the stakeholders involved, the expertise of the requirements engineering team, and the size and complexity of the project.

 JOT: Journal of Object Technology - Engineering Security Requirements
Most requirements engineers are not trained at all in security, and the few that have been trained have only been given an overview of security architectural mechanisms such as passwords and encryption rather than in actual security requirements.
The required application or component response interactions and postconditions of the user case are replaced by the required application or component security-oriented responses and postconditions of the misuse case.
A nonrepudiation requirement is any security requirement that specifies the extent to which a business, application, or component shall prevent a party to one of its interactions (e.g., message, transaction) from denying having participated in all or part of the interaction.

Requirements: the features that the system must have or a constraint that it must satisfy to be accepted by the client - a model of the system that aims to be correct, complete, consistent, and verifiable.
Software requirements express the needs and constraints that are placed upon a software product that contribute to the satisfaction of some real world application, alternately, the properties that must be exhibited in order to solve some real world problem.

 Why Goal-Oriented requirements engineering
The requirements of a stakeholder are often revealed in the process of elaborating a goal (or means-ends) hierarchy.
Analyzing requirements in terms of goal decomposition and refinement can be seen as teasing out many levels of requirements statements, each level addressing the demands of the next level.
This approach to the clarification of requirements is especially appropriate in the case of non-functional requirements (such as flexibility, robustness, reusability, maintainability), where initial requirements can be difficult to make precise.
