Security mechanisms

Security mechanisms

1. Specific Security Mechanisms

   • Encipherment
     • Mathematical Algorithms Not intelligible
   • Digital Signature
     • Electronically sign and verify
   • Access Control
     • access rights to resources
   • Data Integrity
     • enforce integrity of data unit or stream of data units
   • Authentication Exchange
     • ensure identity of an entity by means of information exchange
   • Traffic Padding
     • bits into gaps to frustrate traffic analtsis
   • Routing Control
     • secure routes selection routing changes
   • Notarization
     • trusted 3rd party

2. Pervasive Security Mechanisms

   • Trusted Functionality
     • perceived to be correct with respect to some criteria
   • Security Label
     • names security attributes of that resource
   • Event Detection
     • detection of security related events
   • Security Audit Trail:
     • examination of system records and activites
   • Security Recovery
     • deals with requests from mechanisms and takes recovery actions
