Information Systems and Security
Information Systems and Decision Support
Information Security Principles:
Confidentiality: Restricts access to information to authorized individuals only.
Integrity: Guarantees the accuracy and consistency of data throughout its lifecycle.
Availability: Ensures that information and the systems containing it are accessible when needed.
Cybersecurity Policies and Risk Management:
Policies: Formal statements defining the rules and responsibilities for the secure use of information systems.
Risk Management: The process of identifying, analyzing, evaluating, and treating threats to information security.
Personal Data Protection and Legislation:
Laws regulating the collection, processing, storage, and transfer of personal data.
Example: The General Data Protection Regulation (GDPR) in the European Union.
Compliance requires measures like obtaining informed consent and establishing the right to access, rectification, cancellation, and opposition (ARCO rights).
Ethical Use of Information:
Goes beyond legal and technical aspects, addressing values and institutional responsibility.
Requires using information with respect, honesty, and transparency
Cybersecurity and Information Governance:
Cybersecurity: Protects digital infrastructure from threats and attacks.
Governance: The institutional framework for managing information as a strategic resource.
They are interdependent; security protects the systems, while governance ensures they serve legitimate and strategic purposes.
Types and Functions of Information Systems:
Transaction Processing Systems (TPS):
Management Information Systems (MIS):
Decision Support Systems (DSS):
Enterprise Resource Planning (ERP):
Decision Support Systems (DSS) and Expert Systems:
DSS: Combine databases, models, and visualization tools to facilitate information interpretation and scenario simulation.
Expert Systems: Simulate human expert behavior using a knowledge base and an inference engine to solve problems.
Both tools are designed to assist decision-makers in complex situations.
Database Management and Information Processing:
Database Management: The process of storing, organizing, and retrieving large volumes of information efficiently and securely.
Information Processing: The set of operations that convert data into useful insights for decision-making.
Strategic Alignment of Information Systems:
A fundamental principle to ensure technology contributes to achieving institutional goals.
Requires a dynamic coherence between business decisions and technological decisions.
In practice, this means systems should be designed to add value in key areas like customer experience, operational efficiency, and innovation.
