Chapter 1: X.800 Security Mechanisms Flashcards
What is specific security mechanisms?
Can be incorporated into the appropriate protocol layer in order to provide some of the OSI security services
What are the different specific security mechanisms?
- Encipherment
- Digital Signatures
- Access Control
- Data Integrity
- Authentication Exchange
- Traffic Padding
- Routing Control
- Notarization
What is pervasive security mechanisms?
Mechanisms that are not specific to any particular OSI service or protocol layer
What are the different pervasive security mechanisms?
- Trusted Functionality
- Security Label
- Event Detection
- Security Audit Trail
- Security Recovery
What is authentication exchange?
A mechanism to ensure the identity of an entity by means of information exchange
What is traffic padding?
The insertion of bits into gaps in a data stream to frustrate traffic analysis attempts
What is routing control?
Enables selection of particular physically secure routes for certain data and allows routing changes, especially when a breach of security is suspected
What is notarization?
The use of a trusted third party to assure certain properties of a data exchange
What is trusted functionality?
That which is perceived to be correct with respect to some criteria (e.g., as established by a security policy)
What is a security label?
The marking bound to a resource (which may be a data unit) that names or designates the security attributes of that resource.
