IPS V7 Global Correlation
Dear all,
IPS Correlation update will be done through the Management interface right? So I should confirm the ability of the IPS Management IP address to be able to access internet right?
I did so, but still not able to have global correlation update, what I am having each time I enable global correlation is a boost of traffic generated from the IPS and directed to the outside that is consuming the total internet link bandwidth.
What could be the reason behind this boost, and how may I troubleshoot the reason why the correlation is not being updated.
Regards,
Hi,
I had the exact same problem that I solved to day.
Full connectivity but still the error:

I found a tip when searching that worked for me :

Thanks to: http://doublef.org/archives/cisco-ips-global-correlation-update-failures

Edit: I see a difference in our output, you don't have the ip address in update server field:
Update Server Address = Unknown
Might not bee the same problem.

IPS-4420 Global Correlation status critcal
How to check in the IPS 4420 is Globel correlation license are there or not?
In IDS 4420 IDM event montor page I am facing two below problem
1. Event Retrieval =========== Critical
2. Global Correlation =========== Critical.
I configure IPS box got to the Internet without proxy. But I don't how to check the IPS are connected to Cisco Global Correlation server?
Why its shwoing critcal on Event Retrieval and Global Correlation.Are you planning to use the Global Correlation feature?
Here is the information on Global Correlation for your reference:
http://www.cisco.com/en/US/docs/security/ips/7.0/configuration/guide/idm/idm_collaboration.html
If don't want to use that feature, you can disable that in the sensor health metric section so it's not showing Critical.
Similarly, for Even Retrieval, you can just disable that in the sensor health metric section. This is only useful if your IPS events are retrieved by an external monitoring system, eg: IME.

Hello,
I have received following error in IPS regarding global correlation update
A global correlation update failed: ExecLoadCollabUpdate control transaction failed: Control transaction cannot be completed at this time
is any one aware about this error? is it major issue and affecting IPS? I think this is because correlation update failure.

MARS 6.0.4 reporting for IPS 7.0 Global Correlation Reputation Filtering
Does anyone know if there is a report available in MARS to see what IP addresses were denied by Reputation Filtering on IPS 7.0?
I found a report that shows attacks that were prevented due to global correlation score, but not for packets denied by Reputation Filtering.
Replies are greatly appreciated.
Thanks,
MarkThanks for the reply, but what I am looking for is reporting on what packets were dropped with Reputation Filtering(doesn't have a report in MARS) Not the GLobal Correlation risk rating blocks(Which does have a report available in MARS).

Cisco IPS (global correlation) is downloading lots of updates from the iron-port website
I have query on Global correlation.
Following is the observed behavior
Scenario 1:
Global Correlation Inspection: ON (Standard)
Reputation Filter: ON
Result: Global correlation downloads in bytes or KBs (observed on proxy)
Scenario 2:
Global Correlation Inspection: OFF
Reputation Filter: ON
Result: Global correlation downloads 4-5 MB every 5 Minutes (observed on proxy)
This behavior has been observed on both IPS devices one by one. What we wanted the clarity on is why is does global correlation download so much of data when it is OFF, and downloads only minimal data when ON. The equation does not seem to be right.
Request you for your prompt response.
Regards,
NealBoth global correlation and reputation filtering retrieve updates from the SensorBase network, or IronPort. By default, they communicate with the network every five minutes. This value cannot be changed by the IPS administrator.

Hi,
While enabling Global correlation, I understood that we need to configure proxy or DNS.
Also, I hope that needs to open the port (80/443) on the firewall for the management IP address of IPSto reach the cisco sensor database. If i'm correct what about the destination IP, do we need to enable "any" or specific IP is there.
ACL:
Source (IPS Management IP) -> Port (80/443) -> Destination?Hi,
Global correlation features only contain external IP addresses, so if you position a sensor in an
internal lab, you may never receive global correlation information.
Source (IPS Management IP) -> Port (80/443) -Detination is https://198.133.219.25//cgi-bin/front.x/ida/locator/locator.pl

ASA botnet filter vs ips global correlation
Does the global correlation include the data from botnet filter? On Cisc's site it says this on the global correlation
Customers deploying Cisco IPS can benefit from Global Correlation in multiple ways. First, bad traffic from known sources is stopped immediately. This includes zero-day attacks, for which no traditional threat prevention currently exists, advanced persistent threats (APTs), and botnet command and control trafficHello Matt,
Check the following info:
Cisco ASA Botnet Traffic Filter
This paper focuses on how Cisco Security Intelligence Operations relates to botnet threat identification, and its interaction with the Cisco ASA Botnet Traffic Filter. It is important to realize that a comprehensive security deployment should include Cisco Intrusion Prevention Systems (IPS) with its reputation based Global Correlation service and IPS signatures in conjunction with the security services provided by the ASA security appliance such as Botnet Traffic Filter.
So I would say they both provide you security based on databases from the SIO but they will not be equal on their funcionalities, that is why Cisco recommend to use both when possible,

IPS 7.X Global Correlation in IME question
I was reading in the documentation for the new verison of IME that utilizes the new Global Correlation feature in IPS 7.X.
Quick question: Is the Global Correlation module a separate feature that has to be purchased? If so, do you license it for the IME or do you license it per sensor device? Would anyone be willing to share the cost?The Global Correlation feature is licensed on the sensor rather than IME, but is not a new license, it is the same license used for signature updates. So the Cisco Service for IPS contracts provide the license that works for both Signature Updates and Global Correlation Updates.

Good to hear we do not have to buy an additional license and that global-correlation is included in version 7.0.
Thanks for your suggestion "access to internet", I did a re-re-recheck of my configuration and found out that I had a "little routing issue in one of my routers". I solved this and now it is working.

"Global Correlation" = Critical - Cisco AIP-SSM-20
We are getting this error on both IME and IDM. What causes this, and how does one resolve it?
We are also not getting new events in IME - could this be related to the problem?correct..The sensor must operate in Inline mode so that the Global Correlation features can increase efficacy by being able to use the inline deny actions.

Global correlation / reputation filtering in monitoring mode
We use Cisco appliances primarily in monitoring mode. We'd like to use the IPS reputation filtering / global correlation to alert us when we have connections to "bad" IP addresses (e.g. botnet, etc). Is it even possible to use either of these features for this purpose? According the the following document is appears there may not be alerts for packets denied before signature analysis. Surely that can't be???
http://www.cisco.com/en/US/docs/security/ips/7.0/configuration/guide/cli/cli_collaboration.html#wp1067283
"Note This feature only applies to global correlation inspection where the traffic is allowed if no specific signature is matched. It does not apply to reputation filtering where the packet is denied before signature analysis, and no alerts are generated when packets are denied by reputation filtering. "Just listened to the techtalk on global correlation. about 16 minutes in...."we do not send events just to keep the load quiet". Can someone from Cisco please confirm that this completely naive and poorly engineered facet of the solution still works this way? I'm sorry to sound like an arse, but I am so completely frustrated with the value we get out of these appliances. Apparently, the ASA botnet functionality can do what we want, but not the stand alone IPS appliance....come on Cisco.

RafaelHello Rafael,
Why the status is "not enabled
The status is not enabled because the participation of your IPS in the global correlation is off.
There are 3 states related to Global Correlation:
-Full
-Partial
-Off
Please change that and it should working, You need to have a DNS server set up in your IPS, if not Global Correlation will not work.

Hi,
Will the IPS go offline during a global correlation update? We are running sensor version 7.1.(7)E4 and are noticing drops due to the IPS being unavailable. The timing of theses matches global correlation updates on the IPS.We are receiving the following log entry when global correlation updates.
%ASA-3-420001: IPS card not up and fail-close mode used, dropping TCP packet from InterfaceA:x.x.x.x/xx to InterfaceB:y.y.y.y/yy -
Global correlation can't updated
version is IPS7.0, asa5520-aip-ssm.
Singatrue and IME can be sucessfully updated,
Global correlation can't updated,
the Status of global correlation is Critical.
I saw the website
http://www.cisco.com/en/US/docs/security/ips/7.0/configuration/guide/ime/ime_collaboration.html#wp1053280
and updated following the web page. But can't work it.
How could I update global correlation
or go back old sensorbase?The output provided clearly indicates that the AIP-SSM is unable to resolve the update server address. The server name update-manifests.ironport.com is not user configurable.
Do you have more than one DNS server configured? If so, disable all but the primary DNS server.
If you only have one DNS server configured, please verify the AIP-SSM's management IP address has unrestricted access to the Internet. (At a minimum TCP ports 80 and 443 and UDP port 53).
