MARS 6.0.4 Revised Release Notes

To clear any confusion!, although there has been no announcement, the release notes have been revised for MARS Version 6.0.4

Upgrade to 6.0.4

No important notes exist for the 6.0.4 upgrade.

As you will see, no mention of the "last software release for the CS-MARS 100, 100e, 200, GC, and GCm appliances."

:-)

MARS 6.0.4 Confusion, Explaination

Earlier from the release notes, there was a notice regarding 6.0.4 and supported versions.

Upgrade to 6.0.4

The 6.0.3 release, distributed in April 2009, was the last software release for the CS-MARS 100, 100e, 200, GC, and GCm appliances. Therefore, you cannot apply the 6.0.4 release to these appliance models. For a full list of supported appliance models, see Supported Hardware.

BUT, if you look at the supported versions for 6.0.4 in the same document, it lists the following....

Release 6.0.4 supports the following Cisco Security MARS Appliance models:

Local Controller Appliances: 2^nd Generation

•Cisco Security MARS 25R (CS-MARS-25R-K9)

•Cisco Security MARS 25 (CS-MARS-25-K9)

•Cisco Security MARS 55 (CS-MARS-55-K9)

•Cisco Security MARS 110R (CS-MARS-110R-K9)

•Cisco Security MARS 110 (CS-MARS-110-K9)

•Cisco Security MARS 210 (CS-MARS-210-K9)

Local Controller Appliances: 1^st Generation

•Cisco Security MARS 20R (CS-MARS-20R-K9) as a MARS 20

•Cisco Security MARS 20 (CS-MARS-20-K9)

•Cisco Security MARS 50 (CS-MARS-50-K9)

•Cisco Security MARS 100e (CS-MARS-100E-K9) as a MARS 100

•Cisco Security MARS 100 (CS-MARS-100-K9)

•Cisco Security MARS 200 (CS-MARS-200-K9)

Global Controller Appliances: 2^nd Generation

•Cisco Security MARS GC2R (CS-MARS-GC2R-K9)

•Cisco Security MARS GC2 (CS-MARS-GC2-K9)

Global Controller Appliances: 1^st Generation

•Cisco Security MARS GCm (CS-MARS-GCM-K9) as a MARS GC

•Cisco Security MARS GC (CS-MARS-GC-K9)

And hence the models listed, were listed as supported devices!!!

Well, after getting a couple of messages about this, I think I have solved this mystery.

If you look at the EOL for MARS models 100, 100e, 200, GC and GCm, you will see...

Milestone: End of SW Maintenance Releases Date: App. SW

Definition: The last date that Cisco Engineering may release any final software maintenance releases or bug fixes. After this date, Cisco Engineering will no longer develop, repair, maintain, or test the product software.

Date: April 11, 2009


So its looks like the new version will possibly run on these models, but you are out of time for Maintenance Release support.

Time to look for an upgrade/alternative.

:-)

Cisco MARS 6.0.4 Now Available

Thanks to Csaba for pointing out to me, that Cisco have released MARS version 6.0.4

Surprisingly with some of the rumours out there at the moment, there are some new features in this release, and not just signature updates for the supported products.

You can check out the release notes HERE.

So apart from some cosmetic changes, here is what is new...

New Device Support

The 6.0.4 release of MARS supports the following new device versions:

•Cisco ASA 8.2

•Cisco IPS 7.0

•Cisco IPS 6.2

•Cisco IOS/Switch IOS 12.4 (backward compatibility support)

•Cisco FWSM 4.0.1 and 4.0.4 (backward compatibility support)

•Cisco Security Agent 6.0.1 (backward compatibility support)

Miscellaneous Changes and Enhancements

Botnet Traffic Filter (ASA 8.2) Feature Support—Detect malware that attempts malicious network activity, such as sending private data (passwords, credit card numbers, key strokes, or proprietary data) with ASA Botnet Traffic Filter (BTF).

MARS support for ASA 8.2 introduces the following BTF features:

–ASA Botnet Summary Tab—When monitoring a properly configured Cisco ASA 8.2 device, customers can quickly view Botnet activity on their network using the new summary tab that provides at-a-glance dashboard with the following new reports:

–Activity: ASA Botnet Traffic Filter - Top Botnet Ports

–Activity: ASA Botnet Traffic Filter - Top Botnet Sites

–Activity: ASA Botnet Traffic Filter - Top Infected Hosts

–BTF: System reports—When monitoring a properly configured Cisco ASA 8.2 device, customers can drill down into malicious activity with the following new reports:

–Hosts which have generated phone home activity (top infected hosts)

–Adequate host details (port/protocol, user agent, etc.) required to remediation.

–Top Botnet sites by domain and IP address

–Top Botnet ports detected

–BTF: System rule—When monitoring a properly configured Cisco ASA 8.2 device, a new system rule is available that detects failed phone-home db downloads.

•Cisco IPS 7.0 Feature Support—IPS 7.0(1) contains a new security capability, Cisco Global Correlation, which uses the immense security intelligence that Cisco has amassed over the years.

MARS support for 7.0(1) introduces the following Global Correlation features:

–A new system report that identifies the attacks blocked by Cisco IPS 7.0 (1) over a specified interval.

–Global Correlation scores embedded in query and reporting interfaces allow customers to view reputation data and create customized Global Correlation reports.

•Tunable Query Performance Support—Customers can reduce query wait times by creating custom indexes for commonly run queries.

•E-Mail Notification Update—E-mail based notifications now include top 3 source IPs, top 3 destination IPs, and top 3 botnet sites.

•Future Cisco.com Software Update Support—MARS 6.0.4 includes changes to support a seamless migration from the current Cisco.com software and signature download sites to a new location hosted on Cisco.com. Customers are required to upgrade to 6.0.4 to enable future automated system upgrades, patches, and dynamic signature update support, features introduced in MARS 6.0.1 .

And Finally Very Important

The 6.0.3 release, distributed in April 2009, was the last software release for the CS-MARS 100, 100e, 200, GC, and GCm appliances. Therefore, you cannot apply the 6.0.4 release to these appliance models.

Good Luck

ASA Botnet Traffic Filter Syslogs

"The Cisco® ASA Botnet Traffic Filter complements existing endpoint security solutions by monitoring network ports for rogue activity and detecting infected internal endpoints sending command and control traffic back to a host on the Internet. The Botnet Traffic Filter database accurately and reliably identifies command and control traffic, as well as the domains or hosts receiving the information."

If you are using Cisco ASA8.2, with the Botnet Traffic Filter license, you will know, the ASA will syslog out, when hosts are added to the blacklists etc. Then you can errr, manually mitigate these yourselves, with a shun or ACL. (i`m sure this will get better in the future!)

The current version of MARS 6.0.3 only understand syslogs from ASA 8.1 latest, and thus these new syslog messages, will get determined as unknown events.

I was thinking of creating a parser package, to support these, but unfortunately have not had the time recently.

If you fancy having a go yourselves, you can create either create a parser, and rules, or simply create some rules to look for the text strings in the syslogs below.

Here are the new syslogs, related to the Botnet Traffic Filter feature.....

Update on 6.0.3 Patch

Thanks to Bob Lin, for an update on the 6.0.3 patch I mentioned yesterday.

Incidentally, the 6.0.3 patch and patch readme can both be downloaded from the MARS Miscellaneous CCO site:

http://www.cisco.com/cgi-bin/tablebuild.pl/cs-mars-misc.

It is only required if you encounter one of those two bugs.

Regards,
Bob Lin
CS-MARS Release Manager and Escalation Engineer

6.0.3 Patch Available

Thanks to Jeremy Wood in the MARS User Group for pointing out there is a patch available for MARS release 6.0.3

"I was noticing that I had a bunch of Drop rules that were not

triggering correctly after upgrading to 6.0.3 and in my quest for a

solution ran across a patch here:

Looks like it fixes the following problems:

CSCsz14701 - some drop rules do not drop packets after 602 to 603 upgrade

CSCsz22056 - Mars http access to JBoss Application Server info"

Thanks Jeremy.

Also you may be interested to note that a new version of the Cisco NAC Appliance 4.5 Parser Package is now available, without an import password! 

This is a v2 of the package, without the word Draft. Thanks to Craig Hyps for pointing this out.

You can get this from the MARS Parser exchange under the Netpro Forums on Cisco.com

MARS Troubleshooting Technotes

I notice Cisco have added a new doc, under the MARS configuration examples section on Cisco.com, on Troubleshooting.

You can view the MARS Safe Doc HERE, and the full set of documents HERE.

Worth a read. :-)

Cisco MARS 6.0.3 Now Available

Cisco have released MARS version 6.0.3

Miscellaneous Changes and Enhancements

The following changes and enhancements exist in :

•Credential Automation—Save administrative time by updating many Cisco device credentials in a single operation rather than touching each device definition in MARS. Using a seed file to re-import devices that are already defined in MARS, users can update some credentials for Cisco ASA, Cisco PIX, Cisco IPS, Cisco IOS, and Cisco Switch devices.

•Actionable Incident Notification—This enhancement helps customers decide on the importance of a notification without having to log into MARS. The MARS syslog, e-mail, and SNMP incident notification messages provide incident summary information as well as Top 3 reports. The incident summary will include the rule ID, rule name, incident ID, incident start/end time and incident severity. Top 3 reports include Top 3 destination ports, Top 3 reporting devices, and Top 3 event types.

•Improved Reporting Response Times—This enhancement improves response times of commonly used reports by retrieving event data from memory rather than from the database.

•Exported/Archived Configuration Validation— This enhancement ensures that you do not attempt to restore or upgrade a system using a corrupted configuration file. After exporting or archiving a configuration file, MARS scans the file to make sure it is not corrupted.

New Device Support

The 6.0.3 release of MARS supports the following new device versions:

•Cisco IPS 6.2 (backward compatible mode)
