Arelational databaseis structured to recognize relations among stored items of information.

Multiple tablesin a relational database can have interrelated fields.

These relationships are often managed throughforeign keys, which reference the primary keys of other tables.

This relational model allows for complex queries and data integrity across the database.

Example:Tables such asCustomers,Orders, andProductsin a sales database, whereOrderstable may reference bothCustomersandProductstables to establish relationships.

Integration testingverifies the interactions and data flow between individual software components post-deployment. It is a crucial step in CI/CD pipelines, especially inmulti-tier architecturesystems like web applications.

NIST SP 800-160 Vol. 1 (Systems Security Engineering):

“Integration testing should verify that security functions behave correctly when subsystems or components are combined.”

This test type ensures system cohesion after components are deployed, unlikestatic/dynamic code analysiswhich focuses on code quality and vulnerabilities during earlier phases.

ASecurity Information and Event Management (SIEM)system collects, normalizes, and correlates logs and security events from various devices across both on-premises and cloud environments. It enables centralizedthreat detection,incident response, andcompliance monitoring.

NIST SP 800-137 (Information Security Continuous Monitoring):

“SIEMs are essential for real-time incident detection and response by aggregating and analyzing logs from disparate systems.”

Hybrid cloud environmentsmake log correlation complex, and SIEMs are uniquely suited to bridge cloud and on-prem infrastructure.

An information system is a coordinated set of components designed to collect, store, and process data, and to deliver information, knowledge, and digital products. Organizations use information systems to support operations, management, and decision-making. This includes both the technical components (hardware, software, databases, and networks) and the human components (people and processes).
