2STRM Release Notes

Supported Devices

and OS Versions

STRM 2008.2 R2 supports platforms from multiple vendors. Table 1-1 lists Juniper

Networks device families and operating systems that support NSM. The table

shows whether a device requires STRM to forward logs through NSM.

Note: For STRM to correctly process logs from SA and IC, the logs should be sent

from the devices in WELF format. To enable WELF format on the device: Under

System > Logs > Events > Settings, select the WELF filter for the syslog (STRM)

server entry in this table.

To parse logs from IC devices, the IC device needs to be manually added under

Sensor Devices.

Supported Java

and Browser

Software

STRM supports the following versions of Java and browsers:

• Java version 1.5 and later

• Internet Explorer version 7

• Firefox version 2.0

Resolved Issues This section describes the resolved issues in STRM 2008.2 R2:

Offense Now Includes Associated Events

Previously, if an event associated with an offense included a destination IP

address of 0.0.0.0, the event did not appear in the Offense interface summary or

Events list. This no longer occurs.

STRM Now Reports DDOS Attacks Correctly in the Interface

Previously, after the upgrade process, STRM failed to report DDOS attacks

accurately. This resulted in a significant increase in the number of recorded

offenses. This no longer occurs and the DDOS attacks are reported appropriately.

Resolved Issues 3

Tomcat Server Now Restarts Properly After Upgrade Process

Previously, after upgrading your STRM system, the Tomcat server failed to restart.

This was due to a missing file for the netVigilance Secure Scout scanner in the

upgrade. This no longer occurs and the Tomcat server restarts properly.

NTP Settings Now Persisted After Upgrade

Previously, after you upgraded your STRM system, the NTP settings were not

persisted. This required you to reset your NTP settings using the web-based

system administration interface. This no longer occurs and NTP settings are

persisted after the upgrade process.

Identity Table Now Updated After Upgrade

Previously, after the upgrade process, the identity table was no longer updated.

This may have caused DSMs to no longer function. This no longer occurs and the

identity table is updated after the upgrade process.

Upgrade Process No Longer Fails for Deployments with Encrypted Tunnels

Previously, if your deployment included encryption tunnels, the upgrade process

failed. This no longer occurs.

STRM No Longer Displays FlowViews Error After Upgrade

Previously, after the upgrade process, the following error appeared: Error

initializing FlowViews. This error was caused by an additional line in the

application configuration file that resulted in the FlowViews not being initialized.

This no longer occurs.

Applying Multiple Patches No Longer Corrupts Configuration File

Previously, if you installed multiple patches and enforced the changes (Host

Context component should restart automatically), the STRM configuration file was

corrupted. This caused a disruption in service. This no longer occurs and installing

multiple patches no longer corrupts the system.

STRM Now Able To Effectively Process Events for Large Number of Sensor

Devices.

Previously, if your deployment consisted of a large number of Sensor Devices,

your STRM system experienced reduced performance when events were

processed. This no longer occurs.

During a Restart, an Error No Longer Appears Regarding the Tomcat Server

Any changes to STRM using the web-based system administration interface

requires the Tomcat server to restart. This server may take 1 to 2 minutes to

restart. Previously, if you attempted to access the STRM interface during the

restart, a fatal error message appeared. This no longer occurs.

530-027292-01

4STRM Release Notes

Continuous Use of STRM Over Extended Period of Time No Longer Causes

Interface Failure

Previously, if you continued to use a session of the STRM interface for an

extended period of time, a failure occurred in your browser requiring you to restart

your system. This no longer occurs

Restoring Configuration Information for Deployment with Encrypted

Systems No Longer Fails

Previously, if you attempted to restore configuration information in a deployment

that included encrypted systems and then deployed all changes, the restore

process failed for the encrypted systems. This no longer occurs.

Accessing Right-Click Menu in Event Viewer No Longer Causes Java Error

Using the right mouse button (right click) in the Event Viewer allows you to access

additional menu options. Previously, if pop-ups were disabled in your web browser,

a Java error occurred.

Reports No Longer Stops Generating Multiple Reports When One Report

Times Out

Using the Reports interface, you can schedule multiple reports to generate within

the same time frame. All reports that are scheduled to be generated within the

same time frame are generated sequentially. Previously, when generating multiple

reports and a report in the queue required an extensive amount of time to

generate, the report generator timed out. This caused the current report and all

subsequent reports in the queue to fail the report generation process. In STRM

2008.2 R2, when generating multiple reports and the time to generate a report

exceeds the maximum time limit, the report generator skips the current report and

starts to process the next report in the list. Then, a red exclamation mark appears

beside the report in the Report interface to indicate that an issue occurred with the

generation of the report.

The end <time> Option Now Functions Properly When Checking Log

Integrity

The check_ariel_integrity.sh command allows you to check the integrity of

event and flow logs to determine if the logs have been modified. Previously, if you

attempted to use the end <time> option, no results were returned and no errors

appeared. This no longer occurs.

DSMs Installed Prior to Upgrading Now Appear in User Interface

Previously, any DSMs that were installed prior to upgrading did not appear in the

Sensor Device Type drop-down list box in the STRM interface after the upgrade

process was complete. This no longer occurs. Any DSMs that you install prior to

upgrading now appear in the STRM interface after the upgrade process is

complete.

530-027292-01

Resolved Issues 5

Error No Longer Occurs When Viewing Flows for Application View

Previously, in the Network Surveillance interface, when using the View Flows

function to obtain additional information on the Application view, an error appeared

indicating that no data was found. This no longer occurs.

Event Graphs In Dashboard No Longer Stop Plotting Data After Performing a

Soft Clean SEM

In the Administration Console, you can clean the SIM model using the Soft Clean

option, which closes all offenses in the database. Previously, this action resulted in

the event graphs in the Dashboard to stop plotting data. This no longer occurs.

Accessing the RIght-Click Menu Options in Offense Manager No Longer

Causes Error

Previously, in the Offense Manager, if you attempted to access the menu options

available using the right mouse button (right-click), a Java script error may have

appeared. This no longer occurs.

Reports Now Distributed Properly to Users

Previously, if an administrative user created a report and configured the report to

be distributed to another user, the designated user did not receive the report. No

error appeared and no e-mail was received. This no longer occurs and reports are

distributed properly.

Known Issues and

Limitations

This section describes the known issues and limitations for the following areas:

•General

•Deployment Editor

•Network Surveillance

•Dashboard

•Offense Manager

•Reports

General An auto-discovered EX-Series Ethernet Switch may appear incorrectly as a

“Juniper Networks Routing Platform” device.

Workaround: Add the EX-Series Ethernet Switch manually.

Objects Menu Tree May Not Appear in Equation Editor After Adding a New

Custom View

If you create a new Custom View and then open the Equation Editor, the menu tree

displaying network objects may not appear the first time you attempt to access the

menu tree. However, if you choose a new object using the drop-down list box, the

menu tree appears.

Workaround: Close the Equation Editor window and re-open.

6STRM Release Notes

Configuring an Asset Profile View of 0 Causes Errors

In the STRM System Settings, you can configure the Asset Profile View parameter

to specify the views you wish the system to use when accumulating asset profile

data. By default, the list includes the following views: 1, 2, 15, and 16. If you set a

view to 0, an error appears in the log files. Also, if you upgrade to STRM 2008.2,

any Asset Profile View set to 0 is automatically changed to a value of 16.

Workaround: None.

Exporting Information Using CSV/XML Export may be Blocked Using Internet

Explorer 7

If you wish to download information (such as events, assets, or flows), using the

STRM Export function, you can select the Notify When Done option that enables

the browser to notify you when the download is complete. However, if you are

using Internet Explorer 7, a warning appears requiring you to select an option

menu to download the file. When you select the option menu, the browser

refreshes to the STRM Dashboard and the exported file is not downloaded.

Workaround: In Internet Explorer 7, change the Security Settings > Downloads >

Automatic Prompting for file downloads option to Enable.

Deployment Editor Able to Configure Scanner Assignments for Last Entered IP Address

When configuring scanner assignments, you are able to enter multiple IP

addresses; however, scanner assignment configurations are applied only to the IP

address that was entered last.

Workaround: Create scanner assignments for one CIDR address at a time.

Network Surveillance Graph By Lines Option May Display Multiple Lines with Same Color

When you are viewing a graph that includes multiple network view objects, the

graph may display multiple view objects using the same color since the colors are

based on the network. For example, if you are viewing the Chat, Mail, and Web

components in an Application View, each data set is different, however, since they

are based on the same network, STRM interprets the data as one, displaying each

component with the same color.

Workaround: None

Sentry Wizard Sensitivity Slider Is Reading From Lowest To Highest

When setting the alert sensitivity in the Sentry Wizard, the slider has a reading of 0

to 100. Increasing the slider to a higher number results in a lower sensitivity

reading.

Workaround: Position the slider to zero to increase the sensitivity rating.

Dashboard Time Series Charts Displays 6 Hours as Days

In the Network Surveillance interface, you can create a view and configure the new

view to display data in the Dashboard. However, if you wish to view the data for the

530-027292-01

Resolved Issues 7

new view for a 6 hour time period in a Time Series chart, the Dashboard displays

the 6 hours as a day value.

Workaround: Change the Time Series chart to display 8 hours and then back to 6

hours to refresh the Dashboard.

Offense Manager Sorting Columns in Offense Search Results Causes Interface to Display

Inaccurate Search Results

If you search for offense and then sort a column in the search results, the display

reverts to a list of offenses that is not valid for the defined search.

Workaround: When defining your search parameters, choose your desired sort

option from Sort by drop-down list box.

An IP Address Previously Identified as a Remote Attacker Can Not Be

Created as an Offense When Creating a New Network

Even if your network hierarchy is not defined, STRM can start generating offenses.

However, STRM records all generated offenses as remote offenses since no local

systems are defined in your network hierarchy. If this occurs, any IP address that

has been previously defined as a remote attacker can not be created as an offense

when defining your network.

Workaround: You must restart the Event Correlation System (ECS). From the

command prompt, type service ecs restart. Also, make sure your network

hierarchy is defined.

Overlapping CIDR(s) in Network Hierarchy Configuration Allows Users to

View Assets to Which They Have No Access

If your network hierarchy configuration includes overlapping CIDR ranges, a STRM

non-administrative user is able to view assets for which they have no access. They

can view a list of the restricted assets by clicking Search or Show All in the Asset

Profile window of the Offense Manager. However, an error appears if the user

attempts the edit the asset or view detailed information.

Workaround: None.

Viewing a List of Attackers May Display Blank Pages

The Offense Manager allows you to view a list of attackers for a network. If your

system includes closed offenses that have been removed from the database, the

list of attackers may not return the same number of results as the attacker count. If

the list of attacker results are returned over multiple pages, there may be several

blank pages at the end of the results. All results are included in the output.

Workaround: Click on the previous page to view information.

Exported Attacker List to XML or CSV Does Not Include Target Count

The Offense Manager allows you to export an Attacker list in XML or CSV formats.

Currently, the exported list includes a target count of zero.

Workaround: None.

8STRM Release Notes

Reports A No Response E-mail May be Received When Attempting to E-mail

Generated Report

When you generate a report and attempt to send a generated report to an e-mail

address, the e-mail containing the report is received from the

no-reply.report@qradar.com e-mail address instead of the address specified in

your system settings.

Workaround:

Step 1 Locate the following files:

•/opt/qradar/conf/templates/reporting.properties

•/opt/qradar/conf/reporting.properties

Step 2 In the files, change the reporting address.

From: reporting.report.from=no_reply.reporting@qradar.com

<mailto:reporting.report.from=no_reply.reporting@qradar.com>

To: the address specified in your system settings.

Step 3 From the STRM Web user interface, do a “Deploy All”.
