Summary

The importance of logging and different parameters in log management have been highlighted and discussed. We understood the questions we need to answer when we are setting up a logging system that will assist us at the time of a network forensic investigation. We have seen the importance of clock accuracy, correlation, collection, storage, and a host of other factors in logging.
