![]() ![]() ![]() ![]() In this blog, I will describe a few use cases and offer some guidance on best practices for using admission rules. With admission rules, you can automatically filter such searches and provide users a contextual message to improve their query. Poorly constructed searches impacting high priority workloads is a common occurrence and hard to prevent. We will keep updating LogonTracer reflecting received requests, and your Pull Requests and comments are always welcome.We are expanding the capabilities of Splunk Workload Management by introducing admission rules that you may leverage to control searches that run on Splunk. Please refer to the Wiki for details on how to use the new version. The LogonTracer v1.6 update includes login screen and bug fixes in addition to the above features introduced. We plan to support more complex detection conditions in the future. Although Sigma rules cannot detect all suspicious logons, they should still be helpful in investigating incidents.įigure 6: Downloading Sigma rule scan resultsĬurrently, LogonTracer only supports simple detection rules and does not cover rules that span multiple logs (such as count() in the condition field) or complex condition matching. The investigation results can be downloaded as a CSV file from the sidebar. When uploading an event log, check "Run scan using Sigma rules" and you can see the investigation results. Refer to the Sigma GitHub repository for further information:Ī number of rules for investigating security event logs are also available, and LogonTracer now supports investigating event logs using these Sigma rules. Many Sigma rules are available in the official Sigma repository and can be effectively used to investigate logs. Sigma is a common format for converting log detection signatures so that they can be used by SIEM and various security products. If you wish to change the settings, you can do so from "Delete Access to Case".įigure 4: Case setting screen Sigma Support Next, from "Add Access to Case", specify which users can access the case. You can limit users who can access a case. If you want to use a different case, you can change case from "Change Case". When an event log is uploaded in this state, the log is managed in the created case. By default, the "Default" case is used, which all users can access. Create a caseįirst, create a new case from "Add New Case".Īfter a case is created, you will see that the case is used as shown in Figure 2. Note that the following operations can be performed only by an administrator. The following describes the procedure for log management using a "case". See Neo4j webpage for more information about Neo4j Enterprise Edition. This feature is available when using Neo4j Enterprise Edition as the database for LogonTracer. On LogonTracer, logs are managed in units of "case". When investigating multiple incidents, you may sometimes want to manage logs separately for each incident or investigate multiple incidents simultaneously. For other updated items, please refer to the following release: In addition, Sigma can now be used to investigate the presence of suspicious logs in the event log. Previously, LogonTracer could not investigate multiple incidents simultaneously, but this update adds support for managing multiple logs. JPCERT/CC released the latest version (v1.6) of LogonTracer, a tool to support event log analysis. ![]()
