IOS IPS

If the IOS IPS pkg file is 7MB and after I do a copy tftp://xxx/xxx.pkg idconf, where does the file go? I don't see anything on the flash other than the .xml config files.
Any thoughts?

First, please take a look at http://www.cisco.com/en/US/products/ps6634/products_white_paper0900aecd805c4ea8.shtml.
In summary, the copy command follow the following process:
1. load signature from outside server
2. parse it and read into memory
3. save out to the directory configuration as the ips location, in normal cases, it would be the router flash.
When save the files out, it will save into multiple files in a compressed format, even it has a .xml extension, it is compressed.
Here are the files got saved out:
. -sigdef-typedef.xml
type definition files, defines the engine parameters etc.
. -sigdef-category.xml
signature category file. Just a mapping file map the category to signature IDs
. -sigdef-default.xml
Signature file. Contains all signatures and their parameter definitions
When management by CSM/SDM, it also will save out couple of other files:
. -sigdef-delta.xml
Contains all signature modification information other than the default in sigdef-default.xml
. -seap-delta.xml
Contains all the SEAP configuration changes
. -seap-typedef.xml
SEAP type definition file.
Thanks,

  • Is there a way to automate IOS IPS signature updates without CSM?

    I have a growing number of 891 routers running IOS IDS/IPS. My Cisco vendor has stated repeatedly that CSM is the only way to manage signature updates to multiple routers, but I'm finding CSM to be incredibly tedious and slow. It also wants to manage a lot more than just the IPS policies and signatures which causes other problems.
    I have about 160 routers deployed now and that will grow to at least 600. I have CSM 3.3.1. I'm told 4.x would make it easier becasue it can be configured to ignore more of the non-IPS bits of the router configs, but the upgrade is a big chunk of money that wouldn't be in the budget until at least 2012.
    Is anybody doing this with an expect script or EEM applets or something else? It seems to me that I could manually upload an update to one router and push the resulting XML files to all the other routers a lot easier and faster than I could "discover" a bunch of routers in CSM (and rediscover them every time we make a CLI change), add the routers to a group, apply updates to a sig policy, lather, rinse, repeat..., not to mention troubleshooting the weird errors and completely wron "warnings" that CSM spews.
                   Thanks in advance!

    From IOS version 15.1(1)T, you can configure the IOS IPS to auto update from cisco.com which would help I believe.
    Here is the configuration guide for your reference:

  • 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.

  • Which interface to apply IOS IPS

    Hello,
    I have IOS IPS installed on 4 routers on our network at different sites.  They are 2911 routers, with 2GB ram and i am using the latest signatures from cisco.  Everything is working fine.  I have enabled the basic signatures.  At the moment the ips policy is only applied to the wan interface and not the lan. So in summary:
    interface serial0/0     (wan link)
    ip address x.x.x etc
    ip ips mypolicy in
    ip ips mypolicy out
    exit
    According to cisco i should not bother applying ip ips mypolicy out on the wan interface (serial0/0) but should have ip ips mypolicy in on the fa0/0
    lan interface aswell as the serial0/0 interface.
    interface fa0/0          (lan traffic)
    NO IPS POLICY IN HERE AT THE MOMENT
    anyone got experience on this?
    regards
    Kevin

    Hi Kevin,
    I would say that you have done the right thing, since router are limited in memory we should not enable a lot of signatures and also try to limit the scanning to traffic that we actually need to be scanned.
    In what you have done any traffic that in entering or leaving the WAN interface will be scanned.
    Now if there are more interfaces on your router and you want the traffic between the interfaces to be scanned as well in that case only you should enable IPS on those interfaces.
    Most of the times it is not needed.
    Regards,
    Sachin

  • Cisco IOS IPS on 2811

    Hi,
    Is it possible to install NM-CIDS-K9 Intrusion module on a Cisco 2811 and run IPS 5.0 on it ? i.e. with similar functionality to a IPS 4200 series appliance.
    From what i understand that you can do the above but the module will only work as IDS and not as in-line IPS (ability to drop packets etc) ?
    Are there any routers that can have a Network module running in IPS mode to provide the same functionality as IPS appliance (4200 etc) ?
    Is it correct that IOS IPS is only a fraction of the appliance based IPS ?
    Regards \\ Naman

    I am not really sure if there are any routers that can have a Network module running in IPS mode to provide the same functionality as IPS appliance as such, but the module will only work as IDS and not as in-line IPS

  • IOS IPS/IDS on a BGP Peering Router?

    We have a pair of BP peerings between our network and our upstream service provider.  Since the peering points are geographically distributed and we run a "cold potato" routing policy on our network we cannot guarantee symmetric routing for traffic exchanged with our upstream service provider.
    Yesterday we followed the bouncing ball through the IPS/IDS setup documentation on a Cisco 2901 running 15.2(4)M3 and acting as a BGP speaking peering router at one of our peering points.  Immediately the router started throwing %IPS-6-SEND_TCP_PAK and %IPS-6-TIMEOUT_EVENT messages in the logs.  We also observed that some upstream service provider web sites became inaccessible to our users.  Turning off IPS/IDS on the 2901 restored connectivity for our users to those web sites.
    Three questions:
    Do the default Cisco IOS IPS/IDS rules assume that the router will see both sides of each TCP session?
    Does the Cisco IOS IPS/IDS TCP stream reassembly assume an attack and send TCP RST frames when it doesn't see both sides of a TCP session?
    Should we move the Cisco IPS/IDS functionality from the BGP-speaking routers at peering points to our customer sites, as the customer sites are the only places in our network guaranteed to see both sides of a given TCP session?  (We already perform NAT on the customer site routers for that reason.)

    Hello Bill,
    1) Yes, there are some normalizer functions on some IOS-IPS signatures that will behave like that with this scenarios (Asymetric routing not something good to any kind of security device)
    2) Yes, it will close the connections, I will definetly need to look for specific actions regarding that but you could just check the IOS IPS Signature statistics  on your router , see which is the one triggering the most and then see the action configured for it (and change it if required)
    3) If you cannot change that behavior then it would be safe to tell the router is not a good place to set an IPS or any other kind of firewall configuration unless you set with a weaker security policy (useless from a security standard point of view)

  • IOS IPS and SDM 2.2.a

    Hello everybody!,
    I have installed a Cisco 2821 Router with 12.4(4)T IOS version. And SDM V2.2.a. (enteprise service IOS image).
    The router have 256MB Ram and 64MB flash memory.
    From the SDM Interface cannot upload any .sdf file and cannot edit the signatures and tune de IOS IPS.
    Do you know how i can fix that problem?.
    Thanks for the answers friends.

    Hi,
    To add more info, here is the info on defect filed on SDM for RCP issue and workaround suggested.
    Symptoms:
    Issue 1) Installation of SDM version 2.2a or earlier on a router fails with RCP failure message.
    Issue 2) "Load File from PC" feature of File Management dialog in SDM version 2.2a or earlier
    fails.
    Conditions:
    These issues will be encountered for IOS images 12.4(4)T and above.
    SDM uses RCP for installation operations. This problem occurs because the fix for CSCdu34824 in
    recent Cisco IOS releases has changed RCP behavior. Because of this change, if the RCP client
    uses a non-privileged port , the router RCP server does not respond and the above issues occur.
    Workaround:
    1) For Issue 1 :- Use the copy tftp flash command to copy SDM related files from PC to router.
    2) For Issue 2 :- Use the copy tftp flash command to copy the required file from PC to router.

  • IOS IPS basics

    I'm pretty new to managing IPS. My co is looking at deploying a large number of this and i'm suppose to manage it. i got a few questions
    1. are the available signature in default IOS IPS enough? i fired rentina to an old redhat version OS but i find that the results from IOS IPS is pretty generic.it detects non valid http traffic over ssl but not the vulnerablities used, and it does even detects nmap non tcp port scanning
    2.do you recommend using the default IOS IPS signatures ? if no, any recommendations & standards to follow ?
    3. Any guidance on custom signature development on IOS IPS ?
    4. Any method to manage large numbers of IOS IPS rules/singatures on a single console ? So i can push the signature from a single console to each and every routers. if not, it is possible to copy the signature folders over all the routers to get the same sets on signature on the routers?
    Appreciate any useful informations. Thanks in advance

    1. The Built-in signatures are pretty old and mostly worthless, you may want to disable them and use the latest Signature File available for the IOS-IPS. Your memeory will be the constraining factor as to how many signature you can have enabled.
    2. The signature defaults are a starting place. You will have to spend time doing the analysis of events to see if they're false positives (and many will be) and tune them down, or more likely disable them.
    3. Each signature engine has a fixed 64MB of memory. Turn on too many within that engine (including your custom sigs) and you won't get any. Watch the console log when enabling IPS to see if your build is failing. Some sigs eat more memory than others.
    4. If you have money to burn you can buy Cisco's CSM 3.1, or else keep your signature file(s) on an FTP/TFTP/SCP server and copy them to your routers as needed.

  • IOS IPS auto-update

    Hi,
    I have a couple of questions I hope people could answer:
    1) What recommendations/options are available for downloading signature files to a HTTP/TFTP server prior to having the IOS IPS device pull them from the server?  Is their a way to automate the HTTP/TFTP server downloading the signatures? (Cron job or such)
    2) Does the signature file name change each time a new signature file is released? If it does, would I have to go back to the router to update the URL string that is configured in the ip ips auto-update section? I would hate to have to update 200 CPE devices each time a new signature file is released.
    Hoping someone could answer these or help point me in the right direction to find the answer out.

  • IOS IPS Sig Updates

    It seems like whenever there is an IDS sensor/appliance update for defending against the latest virus/worm but there is no update for IOS IPS signatures.
    Case in point - on June 3 there was an IDS update for W32/Bobax.worm.o S174. The IOS IPS zip file as of today is S169 from May 25, What gives?
    Also, why isn't their any release notes for the IOS IPS zip files to document what was added? That way we can read it to judge if we need to download the zip file or not.

    There are a couple of extra steps in producing the IOS IPS signature update. The IOS IPS solution is a subset of the full appliance solution and is further constrained by memory limitations inherent in the routers that it runs in. Because of this, once the signature development team puts together an appliance update, that update has to be reviewed to make sure that the appliance signatures won't crash the IOS implementation. Any issues found during the review have to be addressed before the IOS update can be posted. This extra review step is the cause for the delay.
    Regarding the release notes. The signatures usable by the IOS solution are a subset of the appliance update. You can look at the appliance update release notes to see what *might* be available. I say might because of the subset issues....

  • IOS IPS Signature-File

    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:

  • IOS IPS and VMS and shunning

    Installed 12.3.14T2 (advanced security) on 2811 router with new
    VMS update to the IDS Management Center (2.1) to support IOS IPS SDEE event monitoring. When I configure a specific signature, there is no option to shun. Only alert, block or reset. Where do you configure the dynamic shuning or "local shun action" that seems to be in all the "new features" of the IOS IPS.
    Configuring the signature to block, alert or reset works fine. Just no options to shun. Also the IPS device does not show up in the device list under Monitoring on VMS, even though it shows up as a device in Monitoring Center Device Page.
    Maybe this is where the problem may lie.

    IOS versions before 12.3(14)T support the following
    actions for IOS IPS:
    - alarm
    - drop (drop just the offending packet)
    - reset (reset tcp connection - works for tcp only)
    Version 12.3(14)T and later (including 12.4 versions) added support for the "local shunning" through two different actions:
    - denyFlowInline
    - denyAttackerInline
    DenyFlowInline creates an ACL that drops all traffic on that connection for a certain idle-timeout.
    DenyAttackerInline creates an ACL that drops all traffic from that source address (including other connections from that source address) for a certain idle-timeout.

  • IOS IPS SIG Updates via IDSMDC

    When using IDSMSC to push out updates for Sensors and IOS IPS devices, the signature update process pushes the updates to the sensors during the udate process. However the IOS IPS devices pulls their signature definitions from the server itself.
    So my question is, do you need to "Generate" and "Deploy" to all IOS IPS devices to insure the devices are updated with the latest signature definitions after the update?

  • IOS IPS for blocking IM and P2P

    Any recommendations on the best way to use IOS IPS to stop P2P and IM?
    I set up a 3845 with 12.3(14)T1 to do this by importing signatures from the latest SDF using SDM. I used the attack-drop, and all IM and P2P signatures I could find. I changed them all to drop and reset. I then applied it to the inside interface of a 3845. I also set up nbar with a drop policy for all P2P traffic.
    The configuration caused very slow web response time for users, including blocked pages. Removing the IPS filter made everything work properly again. The router also stopped rebooting periodically.
    Is there a recommended way to set this up that does not cause slow performance and reboots?

    OK, went back and loaded some upgraded software. Now using 12.4.1 Advanced security IOS on the 3845, and SDM 211. The new 256MB.sdf signature file has all the IM and P2P signatures in it already!
    After applying the IPS inbound on the serial interface, I changed the UDP signatures action to drop and the TCP to drop/reset.
    Everything appears to be working beautifully. Yahoo and MSN messenger get dropped, as well as the peer to peer requests. I am unable to download Bittorrent. Web access is fast, and there is no hesitation by the router in configuring the IPS.
    This appears to be a great solution so far.

  • IOS IPS Signature Updates

    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

    hi,
    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.
