system log

Show Summary Details

Quick Reference

A file which contains information about the accesses that the users of a distributed system make to its resources. Such a log can be configured to contain a huge amount of information about every access to every resource, or it can be configured to contain limited but highly revealing information such as the time pattern of log-ins made by certain users. Security tools can examine such logs and discover abnormal behaviour, such as a user logging in at unusual times of the day, suggesting that an intruder is masquerading as a regular user.
