Event Viewer is a component of Microsoft's Windows NT operating system that lets administrators and users view the event logs, typically file extensions .evt and .evtx, on a local or remote machine. Applications and operating-system components can use this centralized log service to report events that have taken place, such as a failure to ...
To display and monitor the collected logs one needs to use a client application or access the log file directly on the system. The basic command line tools are tail and grep. The log servers can be configured to send the logs over the network (in addition to the local files).
The Security Log, in Microsoft Windows, is a log that contains records of login/logout activity or other security-related events specified by the system's audit policy. Auditing allows administrators to configure Windows to record operating system activity in the Security Log. The Security Log is one of three logs viewable under Event Viewer.
Security event management (SEM), and the related SIM and SIEM, are computer security disciplines that use data inspection tools to centralize the storage and interpretation of logs or events generated by other software running on a network.
Viewing: Network data can be viewed in a graphical web-based frontend. Acknowledging: Users can interact with the software through the web-based frontend to acknowledge alarms or manipulate other notifications. Reporting: Specific reports on network data can be configured by the user and executed through the web-based frontend.
A message or log entry is recorded for each such event. These log messages can then be used to monitor and understand the operation of the system, to debug problems, or during an audit. Logging is particularly important in multi-user software, to have a central overview of the operation of the system.
Event logging: regardless of the event type, a good practice should be to record the event and the actions taken. The event can be logged as an Event Record or it can be left as an entry in the system log of the device. Alert and human intervention: for events that requires human intervention, the event needs to be escalated.
In this case analysis of captured network traffic can include tasks such as reassembling transferred files, searching for keywords and parsing human communication such as emails or chat sessions. Two systems are commonly used to collect network data; a brute force "catch it as you can" and a more intelligent "stop look listen" method.
