It also deals with starting and ending of the service or events. All the events that have met with failure as well as those that have been successfully executed are logged in the system. The log not only describes the event but also indicates the time of its occurrence. In case of failures, error codes are generated. Your log management process is highly facilitated with such stored information in the operating system. 

Audit reports will indicate the authentication attempts made by people, access and control of files, changes in the security polices and accounts and such other events all of which have a direct or indirect bearing on the security aspects of your system or network. Operating Systems thus typically assist the administrator to find out potentially dangerous and unwanted events and to find out reasons for events that are required but failed to set up an enterprise security management.
