Collect Audit Logs

The Authority must ensure that the necessary logs are kept of the use of its information systems and of the disclosure of information from them, if the use of the information system requires identification or other log-in. The purpose of log data is to monitor the use and disclosure of data contained in information systems and to detect technical errors in the information system.

In Cyberday, the owner of the information system may be responsible for controlling the collection of log data from the information system. The organisation documents the content of the logs in more detail for those information systems for which it is responsible for technical maintenance. For other information systems, the owner, in cooperation with the system vendor, checks that the necessary logs are collected.

An appropriate log is generated from the use of the network to enable the detection of actions relevant to cyber security.

The normal state of network traffic (traffic volumes, protocols, and connections) is known. In order to detect anomalies, there is a procedure for detecting events that are different from the normal state of network traffic (for example, anomalous connections or their attempts).

The organization should collect logs from all of it's assets. The collection should be done according to organization's log management process.
