Software Development, Integration and Maintenance

Software development is the process of conceiving, specifying, designing, programming, documenting, testing, and bug fixing involved in creating and maintaining applications, frameworks, or other software components. Software development is a process of writing and maintaining the source code, but in a broader sense, it includes all that is involved between the conception of the desired software through to the final manifestation of the software, sometimes in a planned and structured process. Therefore, software development may include research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products.

The software can be developed for a variety of purposes, the three most common being to meet specific needs of a specific client/business (the case with custom software), to meet a perceived need of some set of potential users (the case with commercial and open source software). System software underlies applications and the programming process itself and is often developed separately.

The need for better quality control of the software development process has given rise to the discipline of software engineering, which aims to apply the systematic approach exemplified in the engineering paradigm to the process of software development.

There are many approaches to software project management, known as software development life cycle models, methodologies, processes, or models. The waterfall model is a traditional version, contrasted with the more recent innovation of agile software development.

A software development process (also known as a software development methodology, model, or life cycle) is a framework that is used to structure, plan, and control the process of developing information systems. A wide variety of such frameworks has evolved over the years, each with its own recognized strengths and weaknesses. There are several different approaches to software development, some take a more structured, engineering-based approach to developing software, whereas others may take a more incremental approach, where software evolves as it is developed piece-by-piece. One system development methodology is not necessarily suitable for use by all projects. Each of the available methodologies is best suited to specific kinds of projects, based on various technical, organizational, project, and team considerations.

Most methodologies share some combination of the following stages of software development:

• Analyzing the problem
• Market research
• Gathering requirements for the proposed software
• Devising a plan or design for the software
• Implementation (coding) of the software
• Testing the software
• Deployment
• Maintenance and bug fixing

These stages are often referred to collectively as the software development life cycle, or SDLC. Different approaches to software development may carry out these stages in different orders or devote more or less time to different stages. The level of detail of the documentation produced at each stage of software development may also vary. These stages may also be carried out in turn (a "waterfall" based approach), or they may be repeated over various cycles or iterations (a more "extreme" approach). The more extreme approach usually involves less time spent on planning and documentation, and more time spent on coding and development of automated tests. More extreme approaches also promote continuous testing throughout the development life cycle, as well as having a working (or bug-free) product at all times. More structured or "waterfall" based approaches attempt to assess the majority of risks and develop a detailed plan for the software before implementation (coding) begins, and avoid significant design changes and re-coding in later stages of the software development life-cycle planning.

There are significant advantages and disadvantages to the various methodologies, and the best approach to solving a problem using software will often depend on the type of problem. If the problem is well understood and work can be effectively planned out ahead of time, the more "waterfall" based approach may work the best. If, on the other hand, the problem is unique (at least to the development team) and the structure of the software cannot be easily envisioned, then a more "extreme" incremental approach may work best.

Software Development Activity

Identification Of Need

The sources of ideas for software products are plentiful. These ideas can come from market research including the demographics of potential new customers, existing customers, sales prospects who rejected the product, other internal software development staff, or a creative third party. Ideas for software products are usually first evaluated by marketing personnel for economic feasibility, for fit with existing channels distribution, for possible effects on existing product lines, required features, and for fit with the company's marketing objectives. In a marketing evaluation phase, the cost and time assumptions become evaluated. A decision is reached early in the first phase as to whether, based on the more detailed information generated by the marketing and development staff, the project should be pursued further

Because software development may involve compromising or going beyond what is required by the client, a software development project may stray into less technical concerns such as human resources, risk management, intellectual property, budgeting, crisis management, etc. These processes may also cause the role of business development to overlap with software development

Planning Process

TPlanning is an objective of each and every activity, where we want to discover things that belong to the project. An important task in creating a software program is extracting the requirements or requirements analysis. Customers typically have an abstract idea of what they want as an end result but do not know what software should do. Skilled and experienced software engineers recognize incomplete, ambiguous, or even contradictory requirements at this point. Frequently demonstrating live code may help reduce the risk that the requirements are incorrect

Although much effort is put in the requirements phase to ensure that requirements are complete and consistent, rarely that is the case, leaving the software design phase as the most influential one when it comes to minimizing the effects of new or changing requirements. Requirements volatility is challenging because they impact future or already going development efforts

Once the general requirements are gathered from the client, an analysis of the scope of the development should be determined and clearly stated. This is often called a scope document

Software Design and Systems Design

Once the requirements are established, the design of the software can be established in a software design document. This involves a preliminary or high-level design of the main modules with an overall picture (such as a block diagram) of how the parts fit together. The language, operating system, and hardware components should all be known at this time. Then a detailed or low-level design is created, perhaps with prototyping as proof-of-concept or to firm up requirements

Implementation,Testing and Documenting

Implementation is the part of the process where software engineers actually program the code for the project

Software testing is an integral and important phase of the software development process. This part of the process ensures that defects are recognized as soon as possible. In some processes, generally known as test-driven development, tests may be developed just before implementation and serve as a guide for the implementation's correctness

Documenting the internal design of software for the purpose of future maintenance and enhancement is done throughout development. This may also include the writing of an API, be it external or internal. The software engineering process chosen by the developing team will determine how much internal documentation (if any) is necessary. Plan-driven models (e.g., Waterfall) generally produce more documentation than Agile models

Deployment and Maintenance

Deployment starts directly after the code is appropriately tested, approved for release, and sold or otherwise distributed into a production environment. This may involve installation, customization (such as by setting parameters to the customer's values), testing, and possibly an extended period of evaluation

Software training and support is important, as software is only effective if it is used correctly

Maintaining and enhancing software to cope with newly discovered faults or requirements can take substantial time and effort, as missed requirements may force redesign of the software. In most cases maintenance is required on regular basis to fix reported issues and keep the software running

Network Integration, Management and Maintenance

Network management:

Network management is the process of maintaining and organizing the active and passive network components. It will provide the services to maintain network components as well as Network Performance Monitoring and Administration. It identifies the fault, Investigate, Troubleshoot, Configuration Management and OS changes to fulfil all the client requirements. Network management allows computers in a network to communicate with each other, control networks and allow troubleshooting or performance enhancements.

Fault management:

Fault management is the process of technology used to keep the administrator who avoids faults within a networked system so that the possibility of downtime is reduced by detecting, isolating and fixing any malfunctions that occur. Maintain active and passive components to disavow fault.

Network fault management can be monitored through programs that send some notifications to the administrator if the network starts to deteriorate in any monitored areas and helps to reduce the impact of a fault that arise in the network.

Configuration management:

The basic function of configuration management is managing the equipment in the network. This includes tracking and managing the equipment in the network including the management of software versions of the equipment.

Configuration management is the process of setting up and keeping track of connections in a network. It contains information about the programs, versions, and updates installed in network computers. Network management helps the network to improve performance and solve any issues that arise.

Performance monitoring:

The performance monitoring function is to monitor how the key parts of the network have been performing. Performance monitoring is user response times if user asks any document or files the response time of the server would be noted and network throughput is determined how fast data is transferred through a network.

It is used to measure the performance of network and users.

Security management:

Security management is essential to network in order to ensure safety, prevent viruses and other threats by implementing antivirus software to prevent viruses entering in a network. Viruses like as files, documents on the internet, spyware.

If a virus entered in a network, it will reduce the performance of the network and makes a fault in the work so it is used to get the backup files to another server in case of an attack so it keeps safe if any data lost is occurred

Data logging and report:

Data logs record all the data and interactions that pass through a certain point in a system, between keyboard and display. If any system failure occurs, the administrator can go to the log and see what might have caused it.

Network management covers the whole network process and monitoring with any trouble in the work and as a useful tool to the administrator to get a detailed report on the performance of the system and usage of the network to report.

Informaton Security

Information Security is not only about securing information from unauthorized access. Information Security is basically the practice of preventing unauthorized access, use, disclosure, disruption, modification, inspection, recording or destruction of information. Information can be physical or electronic one. Information can be anything like Your details or we can say your profile on social media, your data in mobile phone, your biometrics etc. Thus, Information Security spans so many research areas like Cryptography, Mobile Computing, Cyber Forensics, Online Social Media etc.

Information Security programs are build around 3 objectives, commonly known as CIA - Confidentiality, Integrity, Availability

• Confidentiality - means information is not disclosed to unauthorized individuals, entities and process. For example if we say I have a password for my Gmail account but someone saw while I was doing a login into Gmail account. In that case my password has been compromised and Confidentiality has been breached
• Integrity - means maintaining accuracy and completeness of data. This means data cannot be edited in an unauthorized way. For example if an employee leaves an organization then in that case data for that employee in all departments like accounts, should be updated to reflect status to JOB LEFT so that data is complete and accurate and in addition to this only authorized person should be allowed to edit employee data
• Availability -means information must be available when needed. For example if one needs to access information of a particular employee to check whether employee has outstand the number of leaves, in that case it requires collaboration from different organizational teams like network operations, development operations, incident response and policy/change management

Apart from this there is one more principle that governs information security programs. This is Non-repudiation

• Non-repudiation - means one party cannot deny receiving a message or a transaction nor can the other party deny sending a message or a transaction. For example, in cryptography it is sufficient to show that message matches the digital signature signed with sender's private key and that sender could have a sent a message and nobody else could have altered it in transit. Data Integrity and Authenticity are pre-requisites for Non-repudiation
• Authenticity - means verifying that users are who they say they are and that each input arriving at destination is from a trusted source. This principle if followed guarantees the valid and genuine message received from a trusted source through a valid transmission. For example, if take above example sender sends the message along with digital signature which was generated using the hash value of message and private key. Now at the receiver side this digital signature is decrypted using the public key generating a hash value and message is again hashed to generate the hash value. If the 2 value matches, then it is known as valid transmission with the authentic or we say genuine message received at the recipient side
• Accountability -means that it should be possible to trace actions of an entity uniquely to that entity. For example, as we discussed in Integrity section Not every employee should be allowed to do changes in other employees data. For this there is a separate department in an organization that is responsible for making such changes and when they receive request for a change then that letter must be signed by higher authority for example Director of college and person that is allotted that change will be able to do change after verifying his bio metrics, thus timestamp with the user (doing changes) details get recorded. Thus, we can say if a change goes like this then it will be possible to trace the actions uniquely to an entity

At the core of Information Security is Information Assurance, which means the act of maintaining CIA of information, ensuring that information is not compromised in any way when critical issues arise. These issues are not limited to natural disasters, computer/server malfunctions etc.

Thus, the field of information security has grown and evolved significantly in recent years. It offers many areas for specialization, including securing networks and allied infrastructure, securing applications and databases, security testing, information systems auditing, business continuity planning etc.
