Security

Security

Security protects systems, data, services, and operations against unauthorised access, misuse, disruption, and damage.

It also preserves availability and legitimate access for authorised users. Therefore, protection must support business operations instead of blocking them unnecessarily.

Security requirements may define access controls, authentication, encryption, monitoring, auditing, recovery, or availability targets. Moreover, teams should express these needs through measurable and testable statements.

Early analysis helps teams identify threats, legal duties, assumptions, and operational constraints. Consequently, they can address important risks before implementation becomes expensive.

Changes in technology, regulations, or threats may require new controls. Therefore, teams should assess impacts, dependencies, costs, and risks through a controlled change process.

Relevant stakeholders include system owners, developers, operations teams, data protection specialists, and users. In addition, documented decisions and traceability support audits and future reviews.

Clear protection requirements reduce risk, support compliance, preserve trusted access, and strengthen operational resilience.
