The role of the time parameter in a network security management model

We propose an information model and a number of services for managing the security of TCP/IP networks. More precisely, we identify a number of managed objects included in SNMP management information base (MIBs) that are important for security management and we propose a temporal network management model for the historical representation of the security management information. This model incorporates the temporal dimension in the management information model proposed by the Internet Engineering Task Force. Moreover, we define a number of services for the monitoring, storage, capitalisation and analysis of the historical security management information
