The operational part of model provides useful data on the performance of the system. With the collected data, it can lead to creating a better result on the second part of the model which is to define the security controls. Security control provides the measurement of the system. For each phase, there is a certain control that needs to be performed. With the two models combine it†¦show more content†¦Document the high-level concept and bring into the next phase, design phase. The second phase is called design phase. Capture the information from the previous phase and establish a plan. A plan that provides an architectural view to put into action. â€Å"The design phase comes after a good understanding of customer’s requirements† (Alwan, 2015). The design phase is basically creating an action plan for the rest of the process to follow. The third phase is called the development phase. In the development phase, the engineers are focusing on the objectives. The fourth phase is called the deployment phase. During the deployment phase, the development product should fulfill the criteria of the customer. In some life cycle model, this stage usually being called integration, verification, and validation. Moreover, in the deployment phase, this is where the engineering’s object being integrated into the system (Marchant, 2013). The fifth phase is called the operations phase. The operation phase is simply making sure all activities are sustained and function properly. Not only making sure the objects are working, but also providing support, updates, and repairs. The last phase of the SDLC is called the retirement phase. Without the retirement phase, the security vulnerability may be exposed. Disposing the old system and making sure the API, and database is beingShow MoreRelatedThe Paradigm Of Multilateral Security1124 Words   |  5 Pagesdescribing security requirements, as reflected for example in the Common Criteria, an international standard to achieve comparability of independent IT security evaluations, starts with a description of the functional requirements, the system architecture, and its working environment. It then continues with a threat analysis that describes envisaged threats, possibly followed by an evaluation of the severity of threats through a risk analysis and ends with the definition of a security policy.

These measures have made the business world more effective at blocking threats from the outside, and made it increasingly difficult for hackers or viruses to penetrate systems. But there are still threats thatRead MoreApproaches to Risk Analysis Essay912 Words   |  4 PagesWhen planning any kind of project, especially an information security project, risk analysis is very important. Risk analysis, in the context of information security, is the process of assessing potential threats to an organization and the overall risk they pose to the continued operation of the organization. There are multiple approaches to risk analysis, and multitudes of literature have been published on the subject. In their paper published in 2012, Bhattacharjee and associates introduced twoRead MoreSecure Access For Computer Engineering Essay1576 Words   |  7 PagesTHE PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE AWARD OF THE DEGREE OF BACHELOR OF ENGINEERING (COMPUTER ENGINEERING) SUBMITTED BY SHAIKH SHEERAAZ Exam No : PIYUSH WANI Exam No : SURYANSH RAJAN Exam No : PRIYADARSHAN PRABHAKAR Exam No : DEPARTMENT OF COMPUTER ENGINEERING STES’S SMT.
