Meaning
Automated continuous streaming of system activity records provides real-time visibility into the operational state of digital infrastructure. This continuous transmission of audit log telemetry acts as an unalterable history of database and application modifications. It allows security and compliance officers to trace unauthorized access or system errors to the exact millisecond of their occurrence.
Verification Method
Verifying the integrity of streamed event records prevents administrators from silently altering their own historical actions. By writing these records directly to an external, write-once storage medium, the organization establishes a baseline that cannot be modified by privileged users. This practice removes reliance on the memory of operators during an incident investigation.
Operational Cost
Maintaining the infrastructure for high-volume event streams requires substantial data storage and network bandwidth. Organizations must balance the retention period of these detailed records against the cost of the storage media. When log data is discarded too quickly, investigations into historical system failures or security breaches become impossible due to a lack of baseline evidence.
This lack of data can force teams to reconstruct events from incomplete memories, a process that is prone to errors and increases the hours required to resolve disputes.
Analytical Limit
Streamed data of this type can prove that an event occurred but cannot determine the intent of the user who initiated it. It provides the what and when of an action, while the reasoning behind the action must be found in other records.
