Upgrade Instructions
The MARS upgrade packages are the primary vehicle for major, minor, and patch software releases. As administrator of the MARS Appliance, you should check the upgrade site regularly for patch upgrades. In addition to addressing high-priority caveats, patch upgrade packages update system inspection rules, event types, and provide the most recent signature support.
For detailed instructions on planning and performing an upgrade or install, refer to Checklist for Upgrading the Appliance Software in the Install and Setup Guide for Cisco Security Monitoring, Analysis, and Response System.
Important Upgrade Notes
To ensure that the upgrade from earlier versions is trouble free, this section contains the notes provided in previous releases according the release number. Please refer to the notes that pertain to the release you are upgrading from and any releases following that one.
General Notes
Warning
The MARS Appliance performs a file system consistency check (fsck) on all disks when either of the following conditions is met:
•
•
The fsck operation takes a long time to complete, which can result in significant unplanned downtime when rebooting the system after meeting a condition above. For example, a MARS 50 appliance can take up to 90 minutes to perform the operation.
Upgrade to 4.3.5
No important notes exist for the 4.3.5 upgrade.
Upgrade to 4.3.4
No important notes exist for the 4.3.4 upgrade.
In addressing CSCsm57453: Incident not created for some of same events, the behavior now differs between 4.3.4 and 5.3.4. In the x.3.3 releases, incident firing was throttled at 100 incidents for event bursts from a vulnerability assessment (VA) reporting device. In 5.3.4, incidents firing throttles at over 430 incidents, and in 4.3.4, the incidents firing throttles at just over 220 incidents.
Upgrade to 4.3.3
No important notes exist for the 4.3.3 upgrade.
Upgrade to 4.3.2
The following important notes apply to the upgrade from 4.3.1 to 4.3.2:
•
If you've edited a system rule on a Global Controller, you may encounter one of two conditions where the rules on the Global Controller are out of sync with those on the Local Controller.
Symptom: The edited rule in the Global Controller disappears from the list of rules on the Local Controller. (CSCsk12130)
Condition: The user edited a rule on the Global Controller and then upgraded to a different version of the MARS system software and then added of a new Local Controller to the Global Controller.
Symptom: A rule that was edited in the Global Controller looks as if it is an empty rule in the Local Controller and be inactive. (CSCsk19730)
Condition: This occurs under in some cases where a Local Controller is added to a newly upgraded Global Controller.
Work Arounds: If the Local Controller is deleted from and re-added to the Global Controller under x.3.2, the issue should resolve itself. However, in conditions with a large topology or many custom rules, we recommend contacting technical support for a work around that avoids the need to delete and re-add the Local Controller.
Another possible work around if the number of edited rules are small is to edit and make further changes to the rule and activate. In this case, the issue should be resolved for that rule.
•
For example, an IOS 12.4 device is added to MARS 4.3.1 as 12.2 and after the upgrade to 4.3.2, when the discovery occurs for that device, the device type is automatically updated to IOS 12.4. The same is true for devices that are running IOS 12.3. However, if you have not enabled device discovery, use the Change Version feature to change between IOS 12.2, 12.3, and 12.4.
•
•
•
Upgrade to 4.3.1
Beginning with the 4.3.1 and 5.3.1 releases, the dynamic IPS signature updates (if enabled) is an aspect of the version of software running on a MARS Appliance. Therefore, in addition to running the same MARS software versions on the Global Controller and Local Controller, the IPS signature version must match or the communications fail.
In a Global Controller-Local Controller deployment, configure the dynamic signature URL and all relevant settings on the Global Controller. When the Global Controller pulls the new signatures from CCO, all managed Local Controllers download the new signatures from the Global Controller.
In addition, CSCsk90015 states that any reporting device representing a Cisco ACS 3.x device that exists prior to the 4.3.1 upgrade is deleted during the upgrade. To resolve the issue after upgrade, you must the remove the reporting device from the host and re-add that device again as Cisco Secure ACS 3.x.
An example process is as follows:
1.
2.
3.
Upgrade to 4.2.8
No important notes exist for the 4.2.8 upgrade.
Upgrade to 4.2.7
No important notes exist for the 4.2.7 upgrade.
Upgrade to 4.2.6
No important notes exist for the 4.2.6 upgrade.
Upgrade to 4.2.5
The 4.2.4(2432) patch was released to address an issue with the MARS system timezone patch in 4.2.4 (2428). The 4.2.5 update includes the patch, and therefore, you are not required to apply the 4.2.4(2432) patch if you are currently running 4.2.4 (2428). This issue, detailed in CSCsi08897, only affects a few timezones; therefore, many customers would never experience the issue.
Upgrade to 4.2.4
No important notes exist for the 4.2.4 upgrade.
Upgrade to 4.2.3
The 4.2.3 upgrade package is approximately 1.6 GB due to the large number of signatures updated and due to the inclusion of a patch to the database software, which was added to address CSCsg02873. Downloading the PKG file may take up to 7 times longer than previous packages.
Note
To upgrade from 4.2.2 to 4.2.3, follow these steps:
Step 1
a.
raidstatus
Tip
For more information on the raidstatus command, see "raidstatus" in Appendix A, Command Reference of the Install and Setup Guide for Cisco Security Monitoring, Analysis, and Response System, Release 4.2.x.

Special Note for Post Upgrade of a Global Controller/Local Controller Deployment
In a Global Controller/Local Controller deployment upgraded from 4.2.2 to 4.2.3, the communication states between the Global Controller and one or more Local Controllers can be out of sync. This issue is detailed in CSCsh38818.
The Global Controller identifies the Local Controller as Active, and the Local Controller identifies itself as Offline. Toggling "Suspend/Resume" from the Global Controller's Local Controller Management page toggles both states, causing the Global Controller to consider the Local Controller as Suspended while the Local Controller considers itself as Online and resumes pushing information to the Global Controller.
This "out of sync" state affects Global Controller/Local Controller deployments that are upgraded from 4.2.2 to 4.2.3.
To determine whether a Global Controller/Local Controller pair is in this error state, follow these steps:
Step 1
Step 2
Step 3
Step 4
Step 5
Once the error has been identified, follow these steps to exit the error state:
Step 1
Step 2
You can verify that the Global Controller sees each Local Controller as "Suspended" by clicking "Details" for that Local Controller to see if it shows that the Local Controller is no longer Offline - "CS-MARS Local Controller: [hostname]/[zone name]"

Upgrade to 4.2.2
The following issues can occur during the standard upgrade process of a MARS Appliance:
•
The following issues can occur when upgrading your reporting devices:
•
Upgrade to 4.2.1
As identified in CSCse17864, CSCse22610 and CSCse22617, the changes in the case management feature requires that you close all cases before upgrading from MARS 4.1.x to 4.2.1. By closing the cases, you ensure that the device, report, and query information is copied to the case, assuming it still exists in the database.
Upgrade to 4.1.5
No important notes exist for the 4.1.4 upgrade.
Upgrade to 4.1.4
No important notes exist for the 4.1.4 upgrade.
Upgrade to 4.1.3
No important notes exist for the 4.1.3 upgrade.
Upgrade to 4.1.2(2042)
The following notes detail changes to the standard upgrade process:
•
Opening file: /etc/data/secondarytables/reports/Report.0.Resource-Issues--IOS-IPS-DTM---All-Events.x mlIf you do not see this line, then a problem occurred during the upgrade regardless of whether the version command reports 4.1.2 (2040).
•
script -b patch_or_04_1_16.sh
The 4.1.2 (2042) image includes an additional command `script' that cleans the database of the data referenced in CSCsc31386. As a result of running the script, the total upgrade process from 4.1.1 to 4.1.2 (2042) may take much longer than previous releases; it depends on the amount of data stored on the MARS Appliance. For a MARS 200, it could double the normal upgrade time to two hours. To determine whether the script is still running, enter the following command and look for `patch_or_04_1_16.sh' anywhere in the output:
sysstatus -n 1 -b
Upgrade to 4.1.1
The following notes relate to changes in your system or configuration as a result of upgrading to MARS 4.1.1.

Required Upgrade Path
When upgrading from one software version to another, a prerequisite version is always required. This prerequisite version is the minimum level required to be running on the appliance before you can upgrade to the most recent version. Table 1 identifies the upgrade path that you must follow to reach the minimum level required to upgrade to current version.

Documentation Errata
•
To determine whether specific incidents are false positives, MARS uses Nessus 2.x GPL plug-ins and custom scripts mapped to specific MARS event types. MARS does not use Nessus to perform vulnerability assessments or related reporting.
•
The OpenSSH client used by MARS does not support modulus sizes smaller than 768. For example, you cannot discover a device using a SSH login that has 512-byte key.

The following notes describe new behavior based on the resolution of specific caveats. Be sure to check the upgrade notes for each release for important notes on data migration.
Quick Install Notes
It is recommended that users read the Install and Setup Guide for Cisco Security Monitoring, Analysis, and Response System. However, for those users who simply want to get the MARS Appliance up and running, the following two topics, taken from the Install and Setup Guide for Cisco Security Monitoring, Analysis, and Response System, summarize the hardware installation and initial software configuration:
1.
2.
Installation Quick Reference
Table 2 provides an overview of the installation and initial configuration process. Following installation and initial configuration, see the following publications for information on how to use a browser and the HTML interface to fully configure your MARS Appliance to provide the security threat mitigation (STM) services you want from this installation:
•
•
Checklist for Initial Configuration
Initial configuration of the appliance accomplishes several goals:
•
•
•
•
•
•
The following checklist describes the tasks required to initially configure your MARS Appliance. Each task might contain several steps; the tasks and steps within should be performed in order. The checklist contains references to the specific procedures used to perform each task.
1.
Initial configuration requires a console connection to access the CLI. You should establish this connection with the power turned off on the MARS Appliance. Three console connection options exist:
•
•
•
After you have chosen and configured your console connection, you must power up the appliance.
Result: The appliance is powered up and you can see the command line prompt through your console connection.
For more information, see:
2.
The command line configuration is separated into three tasks, each task being separated by a reboot of the appliance. The first task involves performing three to four procedures:
•
•
•
•
Each MARS Appliance has two Ethernet interfaces: eth0 and eth1. The eth0 interface is the dedicated interface used for collecting event data and logs from your network. The eth1 interface is intended for use in an out-of-band management (OOBM) network or for a console connection. Therefore, your default gateway and IP address/mask values should focus on the network connections to be used to monitor the data streams of reporting devices, and these settings should be applied to eth0.
Note
Result: The default password is no longer associated with the system administrative account and the appliance is more secure. Also, the eth0 is configured to communicate on your network. When you complete the IP address configuration changes for either, the appliance reboots.
For more information, see:
•
•
•
•
3.
The second task of the CLI configuration involves setting the hostname of the appliance. The hostname is used to uniquely identify which appliance collects a specific log and which appliance fires an inspection rule. This unique identity is especially important in an environment where Global Controller is running. To complete this task, you must:
•
•
Result: The hostname is configured for the appliance. The appliance reboots.
For more information, see:
4.
The third and final task of the initial CLI configuration involves specifying those settings that help ensure the integrity of the event correlation and complete your network connection, allowing access to the appliance from other hosts on the network. In other words, after you complete this phase, you can connect to and complete the appliance configuration using a non-console connection from any host on your network. To complete this task, you must:
•
•
•
•
•
•
Result: Now you have network connectivity. You can access the CLI interface using an Secure Shell (SSH) client on any host that can reach the appliance, and you can log in to the web interface to complete the initial configuration.
For more information, see:
5.
After you have completed the cable connections to the MARS Appliance, defined the required network connection settings, and specified any additional default routes, you can start the web interface configuration process. Verify the configuration settings of your browser before configuring the MARS Appliance (see Web Browser Client Requirements).
During this phase, you configure the following:
•
•
•
•
•
•
Result: You have configured your appliance to communicate on the network, properly correlate events, and issue system e-mails to a monitored e-mail address.
For more information, see:
•
•
•
6.
The software version determines the currency of signatures, system inspection rules, features, and bug fixes. An important part of your security solution is ensuring that you maintain the most up-to-date software on the MARS Appliance. This process involves preparing an upgrade strategy and selecting a method, determining your current version, identifying the most recent version, and downloading and applying all intermediate versions of the software.
Result: The appliance is running the most recent version of software.
