Log data is vital information that contains records about events that have happened in a network. Log data is essential to monitor the network and understand the network activities, user actions, and their motives.
As every device in the network generates logs, the amount of data collected is huge, and managing and storing all this data becomes a challenge. Log archiving is a process that helps administrators use available storage efficiently.
Most compliance regulations compel enterprises to retain log data for at least a year to facilitate forensic analysis. For instance, section 802 of SOX requires organizations to archive their data for at least seven years.
When log data spanning a longer period of time is archived, it can be loaded back into an analytical solution to identify network activity trends and patterns. These trends and patterns support the design and implementation of preventive security strategies.
Archiving log data by employing compression techniques, as well as storing archived logs in a location that doesn't need to be optimized for quick access, are two good ways to save storage space and reduce costs. Furthermore, since the data can be decompressed and loaded into active databases any time without any data loss, it can still be used for forensic analysis or any other operation easily.
