Study Notes

Security and Privacy Key Concepts

CIA Triad: Confidentiality, Integrity, Availability are fundamental security principles.
- Confidentiality: Protecting information from unauthorized access.
- Integrity: Ensuring data accuracy and consistency.
- Availability: Ensuring systems and data are accessible to authorized users.
Attack Types:
- Passive Attacks: Monitoring network traffic.
  - Examples: Traffic analysis, eavesdropping.
- Active Attacks: Modifying or interfering with network communication.
  - Examples: Replay attacks, Denial-of-service attacks, data modification, masquerading.
Security Mechanisms:
- Authentication: Verifying the identity of users and devices.
- Non-repudiation: Preventing senders from denying they sent a message.
- Encryption: Transforming data into an unreadable format to protect confidentiality.
Security Services: Countermeasures to protect against security attacks.
- Availability Services: Ensuring systems remain functioning even during attacks.
- Security Mechanisms: Techniques like encryption, authentication, and access control to enhance security.
Key Terms:
- Masquerade: Impersonating another entity.
- Replay Attack: Reusing a valid communication sequence to gain unauthorized access.
- Denial-of-Service Attack: Preventing authorized users from accessing a service.
Open Systems Interconnection (OSI): Architecture for network communication.
Traffic analysis: Monitoring network traffic to identify patterns and communication channels.
Eavesdropping: Intercepting unencrypted communication.
Data Modification: Altering transmitted data to gain unauthorized access.
Accountability: Ensuring actions can be traced to a specific user.
