Hello Dr. Robert Strader, Based on this week’s discussion which is based on comparing the classic Software development life cycle (SDLC) to the Microsoft's Security Development Lifecycle(SDL). I would want to say that the Software Development Lifecycle is a structure which defines tasks to be performed at each step in the Software Development. And on the other hand, the Security Development Lifecycle(SDL)is a process which helps developers creating software applications to make them more secure and address the security compliance by reducing development cost. Software and Security: Without software, a computer would simply be an interesting experiment in an engineering lab. The software gives value to computers by using them to support day-to-day …show more content…
In the case of web-based applications software, it must include controls to protect the value of the business and its information from the exposure to end users in the outside world. There is this mediation between end users, the valuable data, and the outside world. Software development life cycle (SDLC): The process by which the software is conceptualized developed and maintained this process is known as Software Development Lifecycle. There are seven key points to understanding Software Development Lifecycle. 1. Planning: This is the process in which the outline of the project is created and why this software is needed is …show more content…
One of the most crucial factors that lead to Microsoft creating secure software is the use of the Security Development Lifecycle or SDL. SDL has been used in the development of Windows 7 Microsoft office, windows internet explorer 8, asp.net-mvc, windows server 2008 and many more products so what is SDL. The SDL is a set of processes and tools designed to minimize the number and potential impact of any security vulnerabilities in a software product these processes and tools are used at every stage of the software development lifecycle beginning with security training for all team members. Requirements phase: The team will identify the key security objectives for the product set the appropriate bug bars that define security and quality for the product lifecycle and perform security and privacy risk assessments. Design phase: The team will undertake a threat modeling exercise to analyze and document the applications attack
In today’s rapidly expanding computer world, growing demands for functionality under shorter time frames have become common place. Software growth has also provided newer economic rewards and possibilities for many companies. As software has become more pervasive in function and usage, security problems regarding the products has become a real issue. Viruses, worms, and hackers have become more dangerous as computers have become more connected and require more complex software. Software, unfortunately, will always be subject to flaws and bugs. Software coding is a distinctly human process and hence subject to human error. It is precisely such errors prevalent within crucial software that can be exploited by malicious individuals. The presence of such hackers is an unwelcome and unfortunate reality; it is the responsibility therefore, of software creators to take into account potential security risks in creating their products. However, reducing security risks means more resources and time spent in a product. For commercial companies, the dilemma exists between providing a safe product and protecting their bottom line. Nonetheless, practical solutions exist for providing security to the software user, involving responsible usage from the user as well as an informative approach from the software companies.
The waterfall methodology flows in a downward fashion, similar to the way water flows downwards, take developers from the high-level initial requirements gathering through the system testing and product shipment. The waterfall methodology create blueprints or plans for the optimal process for software developme...
The boundaries may seem obvious to you, but once a project team starts talking about where the process begins and ends, you will appreciate the clarity the SDD brings to the work.
The approach or the model framework of the project development is iterative and incremental development, that is, iterative and incremental development is a discipline for developing systems based on producing deliverables. Therefore, the basic idea behinds this approach is to develop a system through repeated cycles (iterative) and in smaller portions at a time (incremental), allowing developers to take advantage of what was learned during development of earlier parts of the project. Specifically saying, in incremental development different parts of the system are developed at various times and integrated based on their phases while in iterative development, parts of the system will be revisited in order to revise and improve them. Nevertheless, successful deliverables are acquired through modifying targets of the system consulted by users in order to get feedbacks.
A software development process, also known as a software development life cycle (SDLC) can be explained as a structure, imposed on the development of a software product. The software development life cycle (SDLC) is an umbrella term for the overall process of developing, implementing, and retiring information systems through a multiple step process from initiation, training, documentation , design, analysis, maintenance, and consulting.
This White paper is about Software development life cycle based on agile principles or software development iterative methodology .This white paper contains and talks about Software Development Lifecycle (SDLC) employed to create a major or minor software r...
Within the ‘Software Development Life Cycle’ or SDLC, are two well-known models; The traditional model, commonly known ‘The Waterfall Model’, and the more modern models of which we will be observing the ‘Structured Evolutionary Prototyping’ model. Through this I will show you that while both of these models have their own set of benefits and short comings, they each have their own place within the SDLC and that each is superior in their own area and should be used as such.
As part of developing the need in the initial investigation step in the systems development life cycles (SDLC) process, a constructive method is use case. Use case is a technique for capturing requirements with written scenarios in non-technical terminology that describe how a system interacts with a user or another system (University of Phoenix, Course Syllabus, 2006). There are two fundamental pieces, along with how they relate, to bear in mind: the actors and the goals. The actors are everyone and everything that will use (or be used) by the project progress reports, and the goals, which are what the actors want to achieve. The use case will describe the goals achieved by the actors who perform tasks (Carr & Meehan, 2005).
What is the waterfall methodology? According to several software engineering sites, the waterfall methodology is also known as the linear-sequential life cycle model and also known as the traditional approach to software development. The waterfall model is as follows: Requirement of gathering and analysis, flowing down to, System design, then flowing down to Implementation, followed by Testing, and then Deployment of the system, and the final phase of Maintenance. The idea of the waterfall approach is that once a phase is completed, the process continues to move down the chain until all of the phases are completed and there is a product to deliver; the method is unidirectional. The waterfall approach is known for not allowing changes to be implemented passed the requirement gathering and analysis phase.
“Computers play a key role in almost every sphere of life” (Berry, Terrie). Without them, everything would be different. People all around the world own or used a computer. Whether you are a professional in technology or just an average person, computers are still very important in your everyday life. “No other technology has accessed the world like computers and the use of the Internet have” (Maddox, Amanda). Without computers, consumers would not be able to do half the things as quickly as we can. Advances in computer design have increased its use for different industries, especially in the medical field.
Requirements engineering begins during the communication activity, continues into the modeling activity, and builds a bridge from the system requirements into software design and construction. Through requirements engineering, there is an examination of the context of software work performed. It is essential for the software engineering team to understand all requirements of a problem before the team tries to solve the problem. An identification of specific needs that the design and construction must address is also included. Further is a need for the identification of the priorities that guides the order for the completion of work. This i...
Most of the organizations are possibly taking benefits of web enabled business applications. This consists nearly every type of business application, from simple information sharing to complex monetary levels that puts together countless back-end systems. The optimistic advantages of web enabling applications are many and significant, as well as the ability for improved revenue creation and controlled costs. Nevertheless, the advantages of web applications are always on risks. A lot of simple targets to achieve unauthorized access and ultimately sensitive information are stolen by malicious users and criminals.
Agile software development is a group of software development methods based on iterative and incremental development, where requirements and solutions evolve through collaboration between self-organizing, cross-functional teams. It promotes adaptive planning, evolutionary development and delivery, a time-boxed iterative approach, and encourages rapid and flexible response to change.
Project planning falls in the Planning Process Group which consists of those processes to establish the projects total scope, define the projects objectives, and courses of action to achieve those objectives. During the planning process, all the documents that are needed to carry the project through the project lifecycle will be developed such as the project management plan. Project management requires repeated feedback loops as additional information becomes available and is better understood. The planning process delineates the strategy, tactics, and path to successfully complete the project. With that, the planning of a project must walk through all the those processes from executing, monitoring and controlling through the closing process.
The project will be divided into four phases, each with a certain purpose and timeline to achieve a specific goal.
