Security Mechanisms and Attacks
- A security mechanism is a system or process designed to prevent, detect, and respond to security threats.
Security Attacks
- A security attack is an intentional attempt to compromise the confidentiality, integrity, or availability of a resource.
- Security attacks can be classified into two categories: passive and active.
Security Services
- A security service is a facility or capability provided by a system to enhance its security.
Countering Security Attacks
- Security services counter security attacks by providing mechanisms to prevent, detect, and respond to threats.
Passive Attacks
- Eavesdropping and traffic analysis are examples of passive attacks.
- The goal of a passive attack is to obtain unauthorized access to information without modifying the system or data.
Active Attacks
- Masquerade attacks, replay attacks, and denial-of-service (DoS) attacks are examples of active attacks.
- Active attacks involve modifying the system, data, or traffic to compromise security.
Categories of Active Attacks
