The importance of security in software architecture

System security refers to the processes, measures, and practices implemented to protect information systems from unauthorized access, misuse, damage, or disruption. It includes a wide range of mechanisms aimed at safeguarding the confidentiality, integrity, and availability of data and resources within a system.

System security consists of multiple dimensions, including hardware, software, policies, and human factors, to create resistance against malicious threats and vulnerabilities.

• Personal information: Health insurance policies, medical test results, treatment records, prescriptions, education certificates, transcripts, university grades, and student identification numbers
