In any system like small or large that normal processes consists of login and logout as a main process .In between that two main
process lot of sub process like system wise and user wise will be generated according to user to user or os to os .Let we find the probability of
usage with unknown attack solutions. As usual system process are called Internal and induce or connected processes are external.By using allen
algebra we can analysis the temporal event. Auditing provides a way for an administrator to detect an attack that has already occurred or is in
progress. In addition, auditing can help a developer to debug security-related problems. For example, if an error in the configuration of the
authorization or checking policy accidentally denies access to an authorized user, a developer can quickly discover and isolate the cause of this
error by examining the event log. Good system and network security starts with a good understanding of an organization’s operating
environment. Organizations that have a good understanding of their operating environment and that environment’s limitations and
vulnerabilities – should be able to secure their system relatively easily. Maintaining a high level of system security, however, is an on-going
process that requires continued vigilance and solid organizational policies and procedures. Pro-active system administrators not only keep their
systems patched, but also continuously monitor system and network logs and system resource usage reports for interesting events.
