Recon provides a modern log search and hunt solution powered by a high-performance column-oriented, clustered database.
Recon deploys within the ArcSight Platform. For more information about the other products available within the suite, see the Release Notes for ArcSight Platform 20.11.
This release includes the following features, enhancements, and software fixes:
This release enhances the Search function. The Search function helps you investigate security issues by viewing search results and identifying outlier events.
When users select an event in the Events table, Search opens the Event Details panel. This panel includes a unique URL for the event, which can be shared with colleagues or used to view the details in a separate browser tab.
Users can export the entire set of Event Details to a PDF or CSV file, or choose specific values within the details to export. Also when choosing specific values, users can add them to a search query or use with nsLookup and WhoIs.
To reduce the time needed to create and manage searches, users can configure their preferred Search settings. For example, users can specify a default fieldset, time range (including a dynamic time range), and a default view for Search results. The view can include raw data for events.
You can now specify how often you want searches to expire, and thus be removed from the system. This option enables you to reduce the amount of search results held in the database, thus enabling Search performance. The database purges expired searches at midnight.
Search can display results based on the timestamp associated with each event. The database stores three different timestamps for each event: Database Receipt Time; Device Receipt Time; and Normalized Event Time. For peak performance, Search automatically uses the Normalized Event Time setting. Users can also choose to specify a timestamp as the default setting for all their searches.
This release gives you the ability to create storage groups, which allows you to partition the incoming events data and provide different retention periods based on query filters. Because you can set data retention policies per storage group, you can retain certain high volume events for a short time period and other important events for longer time period.
The query filter enables you to associate a storage group with specific compliance requirements, business needs, or search activities. Recon uses the specified query filters to direct events to the correct storage group. For example, one group might have a filter for categoryDeviceGroup =/ Firewall and another for severity >= 7. If an event does not match any of the active filters, Recon sends the event to the DefaultStorage group. You cannot change the name, query, or rank of the DefaultStorage group.
This release leverages the Reports and Dashboards function previously available with ArcSight Logger only. This function includes MITRE ATT&CK content, enabling you to hunt for undetected threats as well as create charts and dashboard to visualize filtered data with tables, charts, and gauges. The Reporting content comes in the following categories.
Content based on the industry-wide standards set by the Cloud Security Alliance (CSA). This alliance has identified the most significant security threats to the shared, on-demand nature of cloud computing.
Content focused on entities, networks, firewalls, malware, and known vulnerabilities.
Content based on the industry-wide standards set by the Open Web Application Security Project® . OWASP has established a list of the Top 10 security risks to web applications, focusing on the most critical threats to the shared, on-demand nature of web-based applications.
If you have the Report Admin permission, you can configure Reporting to incorporate data from additional sources, such as a relational database or a REST data source containing XML- or JSON-formatted data.
If you have the Report Admin permission, you can add and remove Reporting content, also known as assets, for the reports and dashboards.
This release includes the following software fix that resolves a previous issue:
This release resolves the issue where you might experience a failure when attempting to re-install the product after performing an upgradel. This issue occurred because the installer failed to find the images required for installation. (INST-2545)
The following issues are currently being researched for Recon 1.2.
Micro Focus strives to ensure that our products provide quality solutions for your enterprise software needs. If you need assistance with any issue, visit Micro Focus Support, and then select the appropriate product category.
Issue: When you copy a Search query to create the filter for an outlier model and the query includes a timestamp, Recon erroneously highlights the specified date as if the date or its format were invalid.
For example, you copy a search query that includes the phrase Normalized Event Time = 29/05/20 16:20:39:288. In > , you paste the copied query in the filter field for a new model. The query field underlines the timestamp in red, which is the usual indication that the value is invalid. (OCTCR33I112031)
Workaround: Ignore the highlight that indicates that the copied timestamp value is invalid.
Issue: When you apply a timestamp format to an outlier model, and then change the timestamp format, Recon does not display the model in Available Models.
For example, you create a model in YYYY/MM/DD hh:mm:ss:ms. When you access > , Recon no longer displays the model with the modified timestamp. (OCTCR33I113036)> with the Device Receipt Time = 12/31/19. You then change the timestamp format in > > Date/Time Format to
Workaround: In> > Date/Time Format, select the original timestamp format for the model. Recon displays the model in Available Models.
Issue: When you apply a Custom Range to an outlier model, the system automatically adds 1 hour to the Start Time and End Time. For example, if you enter 08/18/20 05, the system changes it to 08/18/20 06. (OCTCR33I116004)
Workaround: Enter 1 hour less than the desired time. Recon will automatically add 1 hour to the time. For example, enter 08/18/20 04 for 08/18/20 05.
Issue: When you change the time format for existing searches and features, errors might occur. (OCTCR33I112038)
Workaround: You might need to correct the time format for the timestamp.
Issue: In OCTCR33I115040), when you set the Time Zone to Database time zone or Custom Time zone, and then Select Range to Yesterday, Week to Date, Month to Date, and so on, the start time is 6:00 instead of 0:00. Recon also displays the end time incorrectly. (
Workaround: In> > Date/Time Format, set the Time Zone to Browser time zone.
Issue: In OCTCR33I115046), when you set the Time Zone to Database time zone, your ability to search might not work properly. (
Workaround: In My Profile >> Date/Time Format, set the Time Zone to Browser time zone, and then perform the search again.
Issue: When you create a storage group, Recon allows you to enter invalid data in the query filter, such as 12345. (OCTCR33I101043)
Workaround: Use a valid Query Filter. For example:
Existing fields, such as 'categoryBehavior', 'name', 'agentAddressBin', 'destinationPort', etc.
Use the correct SQL language. For more information, see the Reference Manual SQL Lanaguge Elements.
Issue: When creating storage groups, you can enter a filter value such as 12345. The saved searches remain listed after deletion by expiration. (OCTCR33I113045)
Workaround: Reload the browser page to load searches displaying the correct items listed.
Issue: Recon fails to apply the default value of Last 30 Minutes when you set the Default Time Setting to Static. (OCTCR33I116009)
Workaround: None. If you want Last 30 Minutes as your default, use the Dynamic preference and select Last 30 Minutes. Otherwise, use Static and always specific a custom date range.
Issue: When Recon is reindexing, a script Re-creating text index completed displays; however, the process is still running and Recon is not ready for use. (OCTCR33I115036)
Workaround: Do not use the product immediately. Give Recon time to create indexes, and so on.
Issue: Recon might redirect you to the login page but fail to let you enter credentials, when all of the following conditions are true:
You have Recon open in a browser tab;
You have at least three open tabs displaying content for the Reports feature; and
You log out of Recon or wait for any of the tabs to time out.
When you attempt to log in again from any of the tabs, you might see an authentication error. (HERC-9758)
Workaround: If this issue occurs, enter the Recon URL, https://hostname/re, in a new tab.
Issue: After you delete a saved search, the HERC-7827)page continues to display the deleted search. (
Workaround: Refresh the browser page.
Issue: When you add a Lookup List field to a fieldset without also adding the field to the query, Search fails to load. This issue occurs because Search expects the Lookup List field to be part of a join in the search query. (HERC-8220)
Workaround: Remove the lookup field(s) from the fieldset or use the Lookup List in the search query.
Issue: Search fails to return results when you use string-based search operators and the string ends with $. Affected operators might include trim, ltrim, rtrim, md5, lower, upper, and substr. (HERC-9307)
For example, the following type of query will fail:
| eval md5_alias = md5(Hello$)
Workaround: Run the search without the $ at the end of the string. For example:
| eval md5_alias = md5(Hello)
Issue: If the CSV file for your Lookup List contains invalid data, Recon will successfully create the lookup table. However, because Recon ignores the invalid data, the new lookup table will not have any data. Also, you will not receive a notification about the empty Lookup List. (HERC-7129)
Workaround: There is no workaround at this time.
Issue: When you add a CSV containing IP or MAC address fields, the size of those fields can increase when imported as a Lookup List. As a result, the CSV file might exceed the file size limit or the maximum number of records allowed for loading a Lookup List. (HERC-7597)
Workaround: Limit the CSV file size to approximately 50 MB or limit the number of total IP and MAC addresses in the file to 1 million.
Issue: If you narrow the range of time in the Events Timeline then execute a new search, the timeline and the Events table might become out of sync. When this occurs, the table displays a “No events to show” message. (HERC-9901)
Workaround: Perform one of the following actions:
To prevent this issue from occurring, select before executing a new search. This action clears the narrowed time range selection.in the Events Timeline
If this issue has already occurred, refresh the browser. The Events Timeline will update to display the previously selected time range. Then selectin the Events Timeline. The Events table automatically reloads with data that matches the timeline.
Issue: If you change the fieldset after running a search, then leave the Search page or move out of the Search section, Search fails to reset the fieldset to the original setting. For example, you choose the Base Event Fields field set and run the search, then change the fieldset to All Fields. Next you navigate to Saved Searches page. When you return to the Search page, the fieldset is still All Fields rather than reverting to Base Event Fields as it should. (HERC-9865)
Workaround: To revert the fieldset to its original setting, presswhile viewing the Search.
Issue: When you change a time setting for charts in the Data Quality dashboard, the charts automatically updates as soon as you pick the new value. However, if you change the dynamic value, the charts fail to update automatically. (HERC-9913)or to a
Workaround: To refresh the charts, click outside the time selection that you just changed. For example, if you changed theto a dynamic value, click either on a chart or on the .
Issue: Search displays an error and fails to apply a join if an associated lookup list includes the word “user” for a data value. (HERC-8283)
Workaround: None available at this time.
Issue: If you create users in Recon before running the script that enables Reporting, those users automatically get assigned the Report Admin role, which you cannot change.
When you only have a single permission for the reporting roles, Recon does not map the permission to InetSoft accurately because InetSoft expects Recon user permissions in an array. For example, in Recon, by default, the Report User role has only one permission that is Report Admin. So, in that case, you cannot use the Report User functionality. (HERC-10045)
Workaround: Use the Reports permissions (Report Admin, Design Reports, Schedule Reports, View Reports) with at least one other Recon permission. For example, to use the Report User functionality, you can modify the Report User role to include Report Admin and Execute Search permissions.
Issue: For a master, worker, and database setup, the multi-node installation fails when database ssl-enabled is Specified as False. (INST-2796)
Workaround: For a master, worker, and database setup, specify database ssl-enabled as true:
For more information about using Recon, see the additional documentation below.
When applying a query filter to storage groups, you can use SQL language or an existing field:
For example: categoryDeviceGroup='/Firewall' or categoryDeviceGroup='/IDS'
For more information about the correct SQL language to use, see the Reference Manual SQL Language Elements.
The following are incorrect examples of a query filter:
The query categoryDeviceGroupX='/Firewall' will fail because categoryDeviceGroupX does not exist) does not exist)
The query name != 'Outlier' and severity >= 7 will fail because there should be no spaces between the operators (!= or >=) and the values ('Outlier' or 7).
For more information about the software and hardware requirements for your deployment and a tuned performance, see the Technical Requirements for ArcSight Platform 20.11.
Before you begin installing Recon, you must download necessary product installation packages. The installation package also includes the respective signature file, for validating that the downloaded software is authentic and not tampered by a third party.
To review the list of the files and versions to download for this release, see the Release Notes for ArcSight Platform.
Before installing, please review the following considerations:
When you deploy Recon, the default roles common in the ArcSight Platform all receive the permissions to conduct searches. However, these roles do not receive any of the Report-based permissions. Only the Report User role, specific to Recon, has permission to perform all the reporting actions, including the reporting admin actions.
To ensure that Recon users can access both the Search and Report features, either add one or more of the Report permissions to the default roles or create new roles with the permissions. Ensure that any user assigned a reporting permission also has a Search or Admin permission. For more information about assigning roles and permissions, see the Help in the product.
NOTE:Reports do not function appropriately if a user’s role has only Report-based permissions. For example, the default Report user role must have at least one Search- or Admin-based permission. (HERC-10003)
