Study Notes
Information Security Overview
- Information is a valuable asset for many organizations, and its security is crucial to prevent reputation damage and criminal charges.
- The goal of information security is to protect the confidentiality, integrity, and availability (CIA) of information.
Confidentiality, Integrity, and Availability (CIA)
- Confidentiality: Ensures only authorized personnel can access and use information, using encryption and access controls to protect it.
- Integrity: Ensures information systems and data are accurate, and changes can only be made with appropriate permission.
- Availability: Ensures data is accessible when needed, and individuals with proper permission can use systems and retrieve data reliably and in a timely manner.
Basic Information Security Concepts
- Vulnerability: A weakness or flaw in an information system.
- Exploit: A successful attack against a vulnerability.
- Mitigation: Reduces harm posed by information security vulnerabilities or threats.
- Threat: Anything that can harm an information system.
- Risk: Likelihood that a threat will exploit a vulnerability and cause harm.
- Safeguard: Reduces harm posed by information security vulnerabilities or threats.
Mechanisms That Ensure Information Security
- Laws and legal duties: Organizations must follow laws and general legal duties to ensure information security.
- Contracts: Include specific security clauses and safeguards in outsourcing contracts to meet legal obligations.
- Organizational governance:
- Policies: Specifies how an organization must act, and the consequences for failing to act properly.
- Standards: State activities and actions needed to meet policy goals.
- Procedures: Step-by-step checklists explaining how to meet security goals.
- Guidelines: Inform users about information security concerns and suggest ways to deal with them.
Data Protection Models
- Public (Government) model: High interest in confidentiality and integrity.
- Private (Corporations) model: High interest in availability and accuracy.
Test your knowledge on key concepts of information security, including confidentiality, integrity, availability, vulnerabilities, threats, risks, and common concerns like social engineering, phishing, and malware.
