• Example of signature custom IOS IPS devices.

  Hello.

  Does anyone know a simple example to configure and test the custom signature of the IDS MC feature in IOS IPS devices?

  I searched for this topic, and I found an example of detection device about set an alarm when telnet is detected, but I didn t can do in Device IOS IPS because that was not the same parameters.

  Thank you.

  IOS IPS work on traffic that flows THROUGH the router, and not on the traffic flowing on or THE router.

  You should try to telnet to a device through the other side of the router instead of the interface of the router. Also an interface through the IOS IPS interface is not enough as IOS IPS does not work as an ID of sniffing traffic on the local network segment. Traffic must flow through the router.

• 2611XM support IOS IPS?

  I have a T (15) 12.4 running 2611XM, 256 ram, will support the IOS IPS service?

  Cisco IOS 12.4 (15) T, XM 2611 will support IOS IPS service. The feature value must be a set of features in advance. The IOS from Cisco IPS acts as an online intrusion prevention sensor, watching packets and sessions they flow through the router and each packet scanning to match all Cisco IOS IPS signatures. When it detects suspicious activity, it responds before network security can be compromised and records the event through Cisco IOS syslog messages or event of Security Exchange (CETS).

• IPS Signature DataBase - ASA IPS/IOS IPS/IPS 42xx/AIP-SSM

  Hello

  Can someone briefly tell me the details of database signature (number of Signature) among the following devices

  --> ASA IPS/IOS IPS/IPS 42xx/AIP-SSM.

  Thank you

  IPS on ASA/PIX = signatures only 50 or so common

  Module AIP - SSM is same signatures as the Cisco 4200 series sensors. Few minor differences exist (such as signature support IPv6 etc.)

  Please rate if useful.

• Cisco IOS IPS in router 2921/k9

  Hi all

  I have a router from Cisco 2921 box database (error C2921/K9) series with BAse IP IOS (IOS SL-29-IPB-K9) image. I want to activate the function of IOS IPS level on this router now. Based on the Cisco Document, I found that I need to purchase a license additional subscripton enale the IPS feature. My querry is-

  It will build on the IOS for basic IP base or do I have to change the IOS?

  If I need to buy the Licesne subscription, how can I get the part number and the cost for the same thing?

  Do I need to purchase any additional module for this as (NME-IPS-K9)?

  Thanks in advance for your quick help

  concerning

  Sunny

  Hi Sunny,

  You do not need a module (however you might install a module instead function in IOS IPS).

  You need 2 licenses:

  1 - a 'security' for your 2921 license enable the IPS feature:

  SL-29-SEC-K9

  License security (paper) for Cisco 2901-2951 (the two system & spare)

  (if you don't have a router, but you can order it with the license as a Pack: CISCO2921-SEC/K9)

  2 - a signature subscription license, which is part of a contract of "services to SPI.

  A "services for IPS" is essentially a SmartNet contract (including the replacement of equipment, to the TAC, etc) more access to the update of the signature.

  SKU for that start with CON-SU or CON - SUO and depends on what level of service for the replacement of HW, and if you want a replacement service on the spot.

  for example CON - SU1 - 2921SEC - this includes a SMARTnet agreement with 8x5xNBD without on-site intervention

• Comment when upgrading IOS IPS & IME VERSION?

  the last ios for ips is 7.0 (2)

  and the last ime is 7.0.2

  If I have already installed the ime with 7.0.1 but the image of the ips now is 2.0000, should move the ime to 7.0.2?

  If necessary... How to do... I checked the soft EMI, but I can't find the upgrade options, they is any soft for upgrade .pkg

  THX...

  -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

  Another question.

  How to check the version of idm is built within the iamge ios ips?

  The IME 7.0.2 Basic function has not changed since IME 7.0.1 you need not update if you do not want.

  IME 7.0.2 supports more sensors now (increase of support from 5 to 10 sensors).

  To upgrade 7.0.2 IME you can just run the Setup file on top of the existing version. I just make sure you close the IME before the upgrade.

  Here is the read me on IME 7.0.2:

  Hope that answers your questions.

• Update IOS IPS AutoSignature

  Hello

  a. currently IOS - IPS doesn't have the feature to have updates from automatic signing of cisco.com as IPS appliances and make modules.

  Therefore, there is no url on cisco.com auto-signatures updated for IOS - IPS.

  b. you can have your own HTTP/TFTP server where you can keep all the IPS signatures downloaded from cisco.com the IOS - IPS can grab files from this server. The configuration, you are referring to this part of the Setup where you specify the address identification information and the connection to HTTP/TFTP server.

  c. in addition, the same configuration can be made by CCP (IOS - IPS configuration is less bulky via CCP). Attach a screenshot.

• Licenses of IOS IPS

  Salvation of the Forumers

  I have a router C1841 loaded with IOS 12.4 T drive the business forward.

  I is generally responsible to the signature of the IPS (IOS-S556 - CLI.pkg) to the router. Only there is no installation license. It seems success view of the installation using CCP.

  My question is:

  1 will be the IOS IPS without a work permit?

  2. what the license can do beside her able Auto-setting router IPS signing day?

  3. what happens if the trial license expires, any impact next not plus-mise to automatic update on IPS signature?

  Thank you

  Noel

  Hello

  1 will be the IOS IPS without a work permit?

  -Yes, IOS IPS will work without a license.  However, the router will not be able to update signatures.

  2. what the license can do beside her able Auto-setting router IPS signing day?

  -the license allows IOS IPS install update signatures

  3. what happens if the trial license expires, any impact next not plus-mise to automatic update on IPS signature?

  -no impact, except for the fact that IOS IPS can not install new signatures

  You can think of it as pay an annual fee to antivirus subscription.  Yes, the antivirus will continue to work with existing updates.  However, new threats are released all the time, so unless the antivirus is updated, the host is still vulnerable to the latest threats.

  I hope this helps.

• IOS IPS-Signature file

  Hi guys,.

  We recently bought a Cisco ISR 2921 and its documents, it is written that this product has a license for IOS IPS Signatrue file, but there is no IOS IPS GIS file on the Flash memory product.   and while I'm trying to download the Cisco GIS file, it fails.

  Can someone tell me where is another way to download the GIS?

  900 active signatures is quite much for a system that has no dedicated IPS-resources.

  But you can control who and how many signatures get activated on your router:

  In the following example, I first turn off all the signatures and enable those for web servers. So just decide what signatures you need. But don't forget to monitor your router resources.

• Spyware on IOS IPS signatures

  The following document lists three types of signatures of spyware for Cisco IDS Version 4.1. These are available on IOS IPS for new 2800 routers?

  http://www.Cisco.com/en/us/partner/NetSol/ns340/ns394/ns171/ns292/networking_solutions_newsletter0900aecd800fc536.html

  Cisco IDS Active Update Bulletin #114 [Intrusion Detection System Solution] - Cisco Systems

  Yes,

  I just looked in the files of the latest signature S128 for IOS IPS and these documents are available.

  They are, however, disabled by default. So you will have to edit the file and allow it before applying the S128 to the router.

  You can make this change by hand or through SDM V2.0:

  http://www.Cisco.com/en/us/products/sw/secursw/ps5318/products_user_guide_book09186a0080327f8b.html

  (NOTE: I was told that you can change the sigs by SDM V2.0, but there is no specific instructions in the user guide).

  The IOS IPS signature updates are found here:

  http://www.Cisco.com/cgi-bin/tablebuild.pl/iOS-sigup

  If you download and unzip the S128. You can edit the file virtualSensor.xml (another name for the attack file - drop.sdf) and find the 3 signatures you mentioned.

  How can install and active the new IPS IOS definitions?

  I checked all internal investigations of Cisco TAC and the error messages and I couldn't identify the problem. It does not seem you have a memory problem, you have available 15meg. I try three things and then maybe contact TAC to see if they can help.

  1. download the file again just in case it is damaged.

  2. give your file extension .sdf just in case the name of the file ips_sdf into a problem (shouldn't be).

  3 download the homeless, just in case there is an invalid content in the file that you currently have.

  4. it seems that you have installed to SDM. Try the SDM to install signatures.

  I hope this helps, if not repost or give a TAC guys.

• Cisco IOS IPS?

  Hello

  I'm currently studying PSAB NSS by Greg Bastien. I have the following lab scenario and would like clarification on what I see. I want to check the functioning of my installation of IPS, so I ran "angry ip" ip address/port scan on the router. "When I use ' statistical property sh industrial ips I see ' packets 3051:1 verified signature: [0:1]" which means by ' TCP connection window size back ATOMIC. TCP "."

  Is this signature 3051 an indication that the router has seen the scan of IP? and it considered a reconnassaince attack. Are there other ways to check the attack of?

  Hello

  If you see signing warning messages, then that means there is a match and IPS triggers an alert message which is the default setting of a signature.

  In your case, it means only that the signature of 3051:1 saw a package matching, so he comes to save the information. For this signature to the fire (which means for IP addresses identify an attack, he must check the other settings as well).

  If you look into the details of the definition of this signature, it has a global analytical threshold and interval summary settings. Which means the PPE must see this signature are in the interval of summary for the number of times defined in the analytical threshold, then it will validate a signature match, so send the alarm and perform actions defined in the signature.

  In your case, it shows that there is a corresponding signature packet. You might be able to find more information, if you run a sniff and capture your ' angry ip' traffic sent to the router. "

  Thank you

• Sharing the burden of the IDS/IPS

  Hi experts,

  Since it is possible to implement some IDS features on routers and PIX, along with the ID is, in a network where all 3 of these devices exist, is it interesting to implement some features on routers and PIX IDS?

  And, if so, what factors are to be considered in deciding what signatures are enabled on what device?

  In this type of scenario, which are considered best practices?

  Thank you very much

  It is possible to do what you ask. Note that the signature on the IPS appliance is a bigger, more complete than other devices together. The exact mix depends on your network configuration. I would say a finer granularity of inspection closer you to your network. For example, the PIX can perform basic firewall functions and filter most of the low-level, floods and general port scans probe. Some routers are good for the limitation of the flow, the traffic shaping, etc. Then the IPS can inspect flows coming into this challenge, focusing on all traffic that could hurt you (beyond knocking on your front door of firewall). Of course, this is just a scenario. Some people can't stand not knowing what to try to knock on the front door. Others do not want the hassle of trying to reconstitute the papers from three different pieces of equipment so they put things in different orders, such as IOS IPS, PIX. Another focus of exploration is what device you can use as a blocking device, the PIX or IOS router (or IP addresses in the case of mode inline operation).

  Cisco means the blueprint of network SECURITY as a job, starting point architecture. The entire library of SECURITY white papers can be found here:

• IPS module for the 7200

  Is there a PA IPS of the 7206? Similar to the NM-CIDS. I have searched around and have not been able to find anything. If not, I guess that IOS IPS is the only option?

  Thanks in advance.

  Hello

  These are the modules supported by 7200 at this point of time.

  http://Cisco.com/en/us/products/HW/routers/PS341/products_relevant_interfaces_and_modules.html

  On the service modules you must have

  Map of Service Cisco Catalyst 4500 AGM encryption

  Cisco Compression Service adapter

  Cisco VPN acceleration module

  Cisco VPN Acceleration Module 2

  Module Cisco VPN acceleration 2 +.

  http://Cisco.com/en/us/products/HW/modules/ps2957/prod_module_series_home.htmlCisco Catalyst 4500 AGM encryption Service adapter

  I think that the option would go for the IOS IPS feature set which can help you in the realization of the obligation you have to your site.

• help with the new IPS file format

  I'm in IOS (1801-fixed) 12.4.9T that uses the sdf format. I'll probably not upgrade the IOS for awhile.

  Can someone advise if Cisco will continue to make available upadtes IPS to the sdf format?

  Thanks in advance for the forum entry.

  Cisco will continue to support the IOS IPS signature format 4.x based SDF files (for prior release IOS 12.4 (11) T) until June 2008.
