Question

Trusted functionality, security labels, event detection, security audit trails and security recovery are all examples of which type of security mechanism?

External security mechanism
Passive security mechanism
Active security mechanism
Contingent security mechanism

Answer 1

Answer:

Encipherment is used either to protect the confidentiality of data units and traffic flow information or to support or complement other security mechanisms. The cryptographic techniques that are used for encipherment are examined in Chapter 5.

Explanation:

A security audit refers to an independent review and examination of system records and activities to test for adequacy of system controls, to ensure compliance with established policy and operational procedures, to detect breaches in security, and to recommend any indicated changes in control, policy, and procedures. Consequently, a security audit trail refers to data collected and potentially used to facilitate a security audit

Answer 2

Trusted functionality, security labels, event detection, security audit trails, and security recovery are all examples of Passive security mechanism

Explanation:

• The pervasive or passive security mechanism is the mechanism not related to any particular services of security. This mechanism involves five architectures for constructing the framework. It includes- Security labels, trusted functionality, and detection of an event, recovery of security and audit trails of security.
• The functionality makes the other mechanisms effective and trustworthy; to label the resources the security labels are used, the security violation can be detected by event detection, audit trails review and examine records of the system for their adequacy and handling of security issues and the management is controlled by recovery.
