But when I look at the Cisco Feature Navigator I can see that it says additional license required: IOS IPS update.
So do I really need another license in order to configure and use IPS?
If yes, how can I get that license?
Regards,
Laurent
Absolutely correct. You would need to purchase the IOS IPS license to be able to update the signatures. You don't need license to use and configure the IOS IPS, however, you would need license to update the signatures to the latest signature packs.
The license will be called IPS Svc (IPS Subscription).
Hope that helps.

Dears,
I would like to know if we have the smartnet of Cisco ASA with AIP-SSM module, Does cisco also includes IPS signature license along with the smartnet or is it seperately we have to buy?
Thanks & Regards,
JvalinWell purchasing is not an issue here. The contract with the buying vendor states only buying and not support and the contact with support vendor is only support not buying.
So If we buy "Cisco Services for IPS" which covers smartnet (support) as well as signature license it contradicts the above agreement done between the three.
The only solution is see here is to buy devices from the 1st vendor and buy only signature licenses from the 1st vendor whereas enrol only for smartnet of asa/aip-ssm from the 2nd vendor.
1st vendor says - regular signature updates comes under support and not buying.
2nd vendor says - regular signature updates should be bought from the 1st vendor as they are only for suppor of the hardware. -
Cisco IOS based IPS Services Licensing Query
Hi Experts,
We have a Cisco 3945 router at one of our location. Our requirement is to enable the IOS based IPS engine within in the router and would like to load new signature files from cisco website to the router. But i am not much familiar with the licensing part. show version and show ip ips license output has been attached for the reference. Following are my queries.
1) Is this platform and IOS is capable for enabling IPS Engine?
2) Is there any extra IPS Services Contract is required (other than the smartnet Coverage) for this router to enable IPS engine and to load new IPS Signature files from Cisco?
Advanced Thanks and Regards,
Sihanu N1) Is this platform and IOS is capable for enabling IPS Engine?
Yes, it is (3945 with a security IOS image will be able to do it)
2)Is there any extra IPS Services Contract is required (other than the smartnet Coverage) for this router to enable IPS engine and to load new IPS Signature files from Cisco?
No, you are good to go.
I will write a future articule about how to enable this feature on an IOS router so stay tune in my website at http:laguiadelnetworking.com for further information as I will cover all of the details,

Hi Guys,
We have recently purchased a Cisco ISR 2921, and on its docs it is writen that this product has a License for IOS IPS Signatrue File, but on the product Flash Memory there is no IOS IPS Sig-File. and while i try to download the sig-file from Cisco, it fails.
Can any one tell me where is an alternate way to download the sig-file ?900 active signatures is quite much for a system that has no dedicated IPS-ressources.
But you can controll which and how many signatures get enabled on your router:
In the following example I first disable all signatures and enable the ones for web-servers. So just decide which signatures you need. But don't forget to monitor your router-ressources.

License for CSM is Professional. Any idea? please helpHi Peter,
You might not be running the latest service pack for version 3.3.0.
Cisco Security Manager (CSM) customers subscribing to automatic IPS signatures/sensors are required to download and install a Cisco Security Manager Service Pack after December 23, 2010 as the IPS signatures are migrating to a new download location on CCO.
Hence if you are running 3.3.0 then you need to upgrade to 3.3.0 SP2 (Service pack 2)
There was a field notice out on this issue:
http://www.cisco.com/en/US/partner/ts/fn/633/fn63373.html

Is it really possible to revert IPS signatures from CSM
Hi folks,
I've been trying to revert IPS signatures that I deployed through CSM Signature policies to the older release but it doesn't seem to be working. Contrary to it Cisco's CSM guide says:
If you later decide that you did not want to apply a signature update, you can revert to the
previous update level by selecting the Signatures policy on the device, clicking the View
Update Level button, and clicking Revert
I can't imagine it is possible as the signatures are normally compiled into xml files. How would the sensor do it ?
EugeneDuring installation a copy of files that will be replaced or updated during the installation will be copied into a backup directory.
The CLI has a "downgrade" command that can uninstall the last update, and the backup copies will be used to replace the files being removed.
A few things to be aware of:
1) Old configuration will be copied back. So changes made since the update may be lost.
2) This works only for Engine Updates and Signature Updates. Major Updates, Minor Updates, and Service Packs replace the complete operating system so there is too much data to try and make backup copies for.
3) This works only for the last update installed. Once you've downgraded the latest one, you can't downgrade the previous one.
4) This can be done through CLI, and now also available in CSM.
Here are some things to check in your situation where it appears to not be working.
Login to the sensor and execute "show ver".
Does the history in the "show ver" output show a Signature Update package as the last update installed?
If not then either another downgrade was previously done, or a Major Update, Minor Update, or Service Pack was the last package installed and can't be downgraded.
If it can't be done through CSM you might try the CLI' "downgrade" command and see if it works through the CLI or if the CLI gives you an error and explanation. -
Correct procedure to update IOS IPS signatures on 2911 router
What is the correct procedure to update the IOS IPS signatures on an 2911 router?
I know how to download the signatures file (eg. IOS-S556-CLI.pkg) but what is the correct way to install the update?
Thank you in advance!The IPS signature package comes with a list of pre-enabled signatures, hence Cisco does not recommend enabling a lot more other signatures, especially not every single signature as documented.
The reason why is because the package might include retired/old signatures only for references, and not every single signature is required to protect your environment because you might not have the traffic for some signatures, you might not have some end hosts that are written with specific signatures, therefore, it becomes irrelevant if you enable it.
Typically here is how customer would enable/disable signatures:
- Use the default signature that is enabled by Cisco (the default should fit majority of the customers).
- Monitor it for a couple of months
- Disable those that you don't need, and enable others if you think you require it for specific. -
Can anyone help me with the steps of upgrading the IPS signature for the platform ASA SSM-20, IDS 4215, WV-SVC-IDSM-2 via IDM and IME. All the sensors are already upgraded with Engine E4 with signature S480.
Can I upgrade the signature directly from S480 to S507? Please let me know the file which I need to download. Is there any impact while updating the signture like reboot?Hi Gangadaran,
We can apply the same package on all the mentioned platforms. It can be applied to all below platforms:
- IPS-42xx Cisco Intrusion Prevention System (IPS) sensors
- IDS-42xx Cisco Intrusion Detection System (IDS) sensors (except the IDS-4220, and IDS-4230)
- WS-SVC-IDSM2 series Intrusion Detection System Module (IDSM2)
- NM-CIDS IDS Network Module for Cisco 26xx, 3680, and 37xx Router Families.
- ASA-SSM-10 Cisco ASA Advanced Inspection and Prevention Security Services Module (Requires ASA)
- ASA-SSM-20 Cisco ASA Advanced Inspection and Prevention Security Services Module (Requires ASA)
- ASA-SSM-40 Cisco ASA Advanced Inspection and Prevention Security Services Module (Requires ASA)
- AIM-IPS Cisco Advanced Integration Module for ISR Routers
Refer the readme for all details:

All the best!!

How to convert Cisco IPS signatures to a MARS events - no keyword search
I am trying to run a scheduled report looking for the new Microsoft exploit under the IPS S411 release, SIGID 19339.0 and I am trying to form the query looking for the event this falls under without using a keyword search on the SIGID. Does anyone know how to correlate an IPS signature to a MARS event?
Thanks,
MikeWith the help of On-box local event correlation technology you can correlate. On-box local event correlation technology not only enables detection, but actually blocks multi-event attacks and malware in real time, complementing security incident management software such as the Cisco Security Monitoring, Analysis, and Reporting System (Cisco Security MARS) that correlate events across multiple devices.
Integrates with the Cisco Security Manager to correlate security events with the configured firewall rules and intrusion prevention system (IPS) signatures that can affect the security event -
Where do IPS signature save at?
Hi
i successfully load the IOS IPS package into the router, verify via CLI and CCP the IPS signature did compile on the router. (advanced mode, around 588 signature is active)
but it went gone (happened twice), i just want to ensure few things
1. i did shut down my router, and migrate to production site, would it cause by the power off / on then IPS signature missing?
2. i did remove the "ip ips iosips in/out" command that previous apply at my interface, would this cause the IPS disable and gone?
just counldn't figure out why now my router only have 3 signature only..
thanks1. Please use the doc below for reference on how to configure IOS-IPS on the router. I will try to answer your questions using this document.
http://tools.cisco.com/squish/9Be6a
2. You will see in step 2.1 we create directory on flash to store all the signature files and configurations.
e.g:
mkdir
router#mkdir ips
Create directory filename [ips]
Created dir flash:ips
3. In step 4.2 , we configure IPS signature storage location by referencing the directory we created above.
e.g:
ip ips config location flash:
router(config)#ip ips config location flash:ips
This is where the signature files will be stored.
4. In step 5.1 we copy the signature files to the router.
e.g:
router#copy ftp://cisco:[email protected]/IOS-S310-CLI.pkg idconf
Loading IOS-S310-CLI.pkg !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
[OK - 7608873/4096 bytes]
The idconf command compiles the signature after the file is copied.
5. If all the above steps are done correctly, you should see the following files in flash:
router#dir ips
Directory of flash:/ips/
7 -rw- 203419 Feb 14 2008 16:45:24 -08:00 router-sigdef-default.xml <----Contains factory default signature definitions.
8 -rw- 271 Feb 14 2008 16:43:36 -08:00 router-sigdef-delta.xml
9 -rw- 6159 Feb 14 2008 16:44:24 -08:00 router-sigdef-typedef.xml
10 -rw- 22873 Feb 14 2008 16:44:26 -08:00 router-sigdef-category.xml
11 -rw- 257 Feb 14 2008 16:43:36 -08:00 router-seap-delta.xml
12 -rw- 491 Feb 14 2008 16:43:36 -08:00 router-seap-typedef.xml
64016384 bytes total (12693504 bytes free)
6. Make sure you do a 'Router#write memory' before you reload the router. This way the configuration done gets stored and is preserved after reboot.
Also make sure your configuration register on the router is correctly set to 0x2102.

Hi,
Is it possible to update signatures for IOS IPS or do we need to update the IOS to get more signatures?
Thanks and rgds
Rajeshhi,
if you have cisco sdm, then it would be easy to update your IOS IPS signatures. You may need to upgrade IOS of the router only when the ips signature requires you to do it. -
Hi,
I want to to tune IPS signature so that it can make exception of ip addresses.
the signature is 13004 (this is UDP scan signature) i have ciscoworks in my network which scan the network using UDP i dont want to disable the signature i just want to add the ip address of ciscoworks to safe list ( if it exists) i have configured the alert to be sent to my email and i got alot of those emails which says
high 13004-0 "AD - External UDP Scanner" x.y.z.w/src_port(*) 0.0.0.0/dest_port(*)

You want to configure an Event Action Rule for this signature with the IP address of your Ciscoworks host in the Event Action Variable:

Filtering IPs on a IDS/IPS signature
Forgive me, I am pretty green when it comes to manipulting IDS/IPS signatures.
Is there a way to filter an IP or subnet from a IDS/IPS signature?
Senario:
We have 2 ASAs with IPS modules and 2 4260 IDS's, we use IPS Manager Express 6.1 to manage them. I keep getting a mail server that is triggering signature 5748-x because its sending a helo verb instead of a noop. This is fine for this paticular mail server. So i would like to remove its IP or filter its IP from the signature so when this happens the signature doesnt fire. However I dont want to disable the signature in case it happens somewhere else.
any help is greatly appreciated.
e-It's not really too bad. I would encourage you to read still though;-)
Each signature can be configured with any number of actions. by default, a lot of them have the "product alert" action.
event action filters are basically a way to suppress all or some actions based on various criteria, like sigid and source (attacker) ip address. I've attached an example. -
Anyone else notice IPS Signature 1548/0 firing frequently?
Hello.
We have seen IPS Signature 1548/0-"Microsoft Offic Picture Managed Memory Corruption" trigger frequently on image files downloaded from IP addresses associated with Microsoft, in the range of 207.46.0.0/16. This has happened for several different customers we manage and I'm wondering if anyone else has seen this new signature fire frequently.
It looks to me that this signature has not been tuned correctly by Cisco because in every case the "Source" IP in the alert was from Microsoft. Just wondering if anyone else has seen this too.
Jon.The signature will be disabled and retired in an upcoming signature update. The new signature will have an updated benign triggers section to reflect that this sig may trigger on potentially benign traffic. In the meanwhile , please feel free to disable and retire this signature. Let me know if you have any additional questions.

Anyone else notice IPS Signature 1802/0 firing frequently?
We have seen IPS Signature 1802/0-"Ruby on Rails Remote Code Execution Vulnerability" trigger frequently on any webpage with XML with YAML content I'm wondering if anyone else has seen this new signature fire frequently.
It looks to me that this signature has not been tuned correctly by Cisco. We don't use Ruby on Rails anywhere in our environment, so we went ahead and disabled the signature, I'm just wondering if anyone else has seen this too.Logged a TAC case and they are working on an update. You are correct this is a signature issue. No time table given. Since the new signature will replace the old one, they recomended we disable the current signature if the alerts were too much.
