Guide: Security Requirements Gathering

Security Requirements Gathering is a crucial step in the Software Development Life Cycle (SDLC) which helps to ensure that necessary security controls are integrated into a software system from the very beginning.

Importance: The method is important as it helps to identify security-related functionality that the system should have and also determines constraints, guidance, and parameters that the system should operate within. Ensuring security controls early in development can help prevent issues down the line, making the system more secure and less susceptible to vulnerabilities or attacks.

Working: Security Requirements Gathering usually works by identifying the critical assets of a system that need protection, determining potential threats and their severity, and defining security objectives and requirements based on these elements.

Exam Tips: When answering questions on Security Requirements Gathering in the exam, remember this process is always about ensuring system security from the beginning of the SDLC. Be aware of its importance in identifying threats and protecting critical assets. You may have scenarios where you need to identify assets, threats, or determine suitable security objectives based on given information. Understanding and explaining the importance and workings of Security Requirements Gathering accurately can gain you crucial points.
