Study Notes
Information Security Principles
- Integrity: Ensures that information is accurate and has not been tampered with, focusing on preventing unauthorized modification or deletion.
- Availability: Ensures that information is easily accessible to authorized users when needed, focusing on reliability and uninterrupted access.
- Confidentiality: Ensures that information is kept secret and protected from unauthorized access, focusing on preventing interception and disclosure.
Information Security Attacks
- Integrity attack: An example is tampering with data, such as altering financial records or modifying sensitive information.
- Availability attack: An example is a denial-of-service (DoS) attack, which aims to make a system or network unavailable to users.
- Confidentiality attack: An example is eavesdropping, which involves intercepting and accessing sensitive information without authorization.
Importance of Information Security Principles
- Availability: Ensures that information is accessible when needed, which is critical for business operations and decision-making.
- Integrity: Ensures that information is accurate and trustworthy, which is essential for making informed decisions and maintaining trust in an organization.
- Confidentiality: Protects sensitive information from unauthorized access, which helps to prevent financial losses, reputation damage, and legal liability.
Access Control and Information Security
- Access Control: Involves allowing different levels of access to information based on importance, using techniques such as role-based access control and mandatory access control.
- Privileges: Ensuring that users have the appropriate privileges to access and manage information, which is critical for maintaining confidentiality, integrity, and availability.
Information Security Concepts
- Data Breach: A severe breach of confidentiality, involving unauthorized access to sensitive information, which can result in significant financial and reputational losses.
