What does the System Development Lifecycle (SDLC) involve?

The System Development Lifecycle (SDLC) is a structured process used for developing software systems and applications. It encompasses a series of stages that guide the development process from conception through to completion and maintenance. The primary stages involved in the SDLC typically include planning, requirements gathering, designing, developing (or coding), testing, deploying, and maintaining the software.

The planning phase involves defining the scope and objectives of the project, determining the resources needed, and creating a project timeline. During the designing phase, the software's architecture and user interface are planned out to ensure that the final product meets user requirements. Implementation entails the actual coding and creation of the software according to the designs.

This comprehensive approach ensures that the software is built in a systematic way, reducing the risks of project failure and increasing the likelihood of a successful deployment that meets user needs.

In relation to the other options, managing user permissions in a database focuses primarily on access control and security for data, which is only a small aspect of the broader SDLC process. Monitoring network traffic for security threats pertains to cybersecurity practices and operational security, rather than the development phases of software. Finally, encrypting sensitive information is a specific security measure that can be implemented during development but does not encompass the entire lifecycle of
