SCM Software Configuration Management What? SCM is a software engineering discipline consisting of standard processes and techniques often used by organizations to manage the changes introduced to its software products. SCM helps to eliminate the confusion often caused by miscommunication among team members. The SCM system controls the basic components such as software objects, program code, test data, test output, design documents, and user manuals. Who? The Software Engineering Institute (SEI) advocated a standard definition for CM oriented to software, broadening the definition of the Institute of Electrical and Electronics Engineers (IEEE) and the guidelines of the International Organization for Standardization (ISO). Why? Is software engineering practices associated with software configuration management offer a number of opportunities to address requirements found International  Standard, ISO 9001. From management perspective, the principles and practices ...

Network and Wireless Security

"Wireless networks are inherently insecure" (Lawrence, 2018). "Wireless network security primarily protects a wireless network from unauthorized and malicious access attempts". (Technopedia, 2018) There are 3 indispensable wireless security protocols: WEP, WPA, and WPA2, each with their own strengths, and weaknesses. In addition to preventing uninvited guests from connecting to your wireless network, wireless security protocols encrypt your private data as it is being transmitted over the airwaves. To further understand these protocols we need to define each one of them: Wired Equivalent Privacy (WEP): The original encryption protocol developed for wireless networks. As its name implies, WEP was designed to provide the same level of security as wired networks. However, WEP has many well-known security flaws, is difficult to configure, and is easily broken. Wi-Fi Protected Access (WPA): Introduced as an interim security enhancement over WEP while the 802.11i wire...

Software requirements elicitation and specification Functional and non functional requirements

Software requirements elicitation and specification Functional and non functional requirements Requirements Elicitation is the process to find out the requirements for an intended software system by communicating with client, end users, system users and others who have a stake in the software system development. Requirement Elicitation Process: Why is requirement elicitation necessary? Knowing what problems to be solved and recognizing system boundaries. Identifying who are the stakeholders. Recognizing the goal of system is the target to be achieved. Software Requirement Specification is a document created by system analyst after the requirements are collected from various stakeholders. Defines how the intended software will interact with hardware, external interfaces, speed of operation.   The functional requirement is  describing the behavior of the system  as it relates to the system's functionality. F unct...
