IPS-4240 fail open

• IPS-4240 design question

  I have two IPS 4240 s that can be placed between our internal network and our extranet firewall. The game of firewall is your pair of standard assets/ASA-5520 switch connected to both switches.

  Q1 - if I'm not worried about atomic attacks, is there another advantage that IPS inline on promiscuity?

  Is Q2 - If inline or promiscuity, necessary to connect the unique IPS for two switches in order to receive packets when a failover of the SAA occurs? If so, does physically or through RSPAN?

  Q3 - if the IPS fails and it is set online, interfaces fail open (traffic continues to pass) or closed (traffic is removed)? I couldn't find that on the Cisco site.

  Thank you!

  "Promiscuous" mode, you can use a 4240 and extend the output of each switch in two interfaces of remote sensing of the 4240 (it has four available). A single 4240 should even be able to set up TCP sessions that span the two rails, as in the case of a failover.

• Sourcefire Appliance virtual Fail Open?

  Hello

  Is it possible for sourcefire IPS appliance can fail open? I guess this would be a definite no, but I can't find a reference to this anywhere.

  Thank you.

  It is an emphatic "no"

• IPS 4240 - additional card

  Hello

  Does anyone know, when will be available 4xFE cards for IPS-4240 (for total 8 interfaces)?

  Kind regards

  Krzysztof

  The option card for IPS-4240/4255 sensors will be a card 4GE to support copper (RJ45) and fiber (SX) connections. It will allow a total of 8 RJ45 interfaces or 4 SX fiber interfaces (and 4 RJ45 interfaces) on these platforms. Unfortunately, it will be probably available for another 9 months or more.

• Deployment of Cisco IPS 4240 devices

  I can't find all the information about the Cisco IPS 4240 features massive deployments. I have 6 devices, I intend to drive to several remote sites and tie in a centralized unit of Cisco MARCH. Without the help of any CSM/LMS software, is there a quick and dirty to pull this off? I think to set up a single IPS appliance, then pull and distribute the configuration file for the remaining devices. I would like to see how others have done this...

  If all of your sensors are of the same type (all 4240 to your situation) and will execute all the even correct configuration, then the copy command will help out you.

  There is a new feature added to the copy command in IPS 6.1 which will help you during the copying of config of one sensor to another.

  Complete you configure a sensor (using IME, IDM or CLI). When you are satisfied with the configuration, and then use the command copy to copy ON a server of SCP.

  Now bringup a second sensor and configure basic networking through the Installer settings (ip address, gateway, etc...).

  Now, use the command copy to copy the first configuration of sensors from the SCP server in the running of the second probe configuration on the second.

  It will ask you to change the network settings on the second probe.

  Answer n °

  The rest of the configuration of the probe first copy will be placed in the second sensor.

  The second sensor will keep its own unique IP address but win the rest of the configuration of the config of the first probe.

  Continue to do this with additional sensors.

  The process can then be repeated every time that additional changes are made to the first sensor.

  Remember though that this only works if the configuration of the probe will be exactly duplicated (including what interfaces would be monitored and how).

  If each sensor will have some unique tunings, then you need to manage each sensor on its own or buy CSM which can be used to share only parts of the configuration of multiple sensors.

  No, do not reimage system (IPS-4240-K9-sys-1.1-a-7.0-2-E4.img), which would eliminate all of your configuration.

  Just perform the upgrade using this upgrade file: IPS-K9-7, 0-2 - E4.pkgand which would automatically be updated to 7.0.2 (E4).

• The Upgrade Version of the engine on IPS-4240

  Hello

  I'm running a sensor IPS 4240 with engine Version 7.0 (1) E3 and the sensor will always have a strong canvassing from 97 to 98%. It's recommended to update the sensor to the latest version of the engine, considering the amount of load top right now?

  Thank you

  Kiran

  Hi Kiran,

  You need to update the engine at it, since you cannot use the latest signature definitions without being on the latest engine.  As long as you don't see packets ignored at the level of the interface of detection, it is fine for the use of the CPU which is high.  If you start to see rejected the packages that you need to reduce the amount of traffic being sent to the probe or reduce (by clearing and retreating) the number of signatures inspection of the traffic on the sensor.

  Best regards

• Not entirely taken TLS supported in Cisco IPS 4240

  I am trying to contact a Cisco IPS 4240 device while having security settings FIPS enabled on the client using SSL. This is not possible because the device does not support TLS extensions in the Client Hello packet (RFC 5746) sent by the client when using TLS (SSL3 and lower are not FIPS compatible). The IDM application that communicates with the device does not send these extensions (im seeing this with WireShark) TLS is able to connect to it.

  Is it possible to provide the 4240 support these TLS extensions?

  This is related to the bugs below.  The original solution will be included in the 7.1.5 release which is preparing to take in charge the platform 4240 among others.  This will allow the Web server IPS to ignore short-term extensions.  The long-term solution will require an update to the Web server so that it is fully compliant with RFC 5746.

• IPS-4240 Sig Update License

  Is this not the right part. the update of the GIS 4240 IPS license?  CON-SUSA-IPS4240S

  I can only find this part number in the ordering tool: CON-SUI-IPS4240, which also has a SMARTNet Support?

  What is do we need just to have updates of GIS?

  Thank you

  You cannot buy a stand-alone appliance IPS IPS subscription.

  You can buy either of the following:

  (1) CON-SUI-IPS4240 for example which includes Smartnet for hardware, software, and the IPS subscription.

  OR /.

  (2) CON-SUSA-IPS4240 contracts are sold only to customers who have purchased a support hardware and software through a reseller/partner contract.

  CON-SUSA... cannot be sold on its own, it must be sold in conjunction with the reseller/partner support contract.

  Hope that helps.

• IPS 4240 high availability?

  Hello

  4240 running in HA mode?

  Or should I look at 4255 if I need to work in HA mode?

  Kindly help me with this info... Thanks in advance.

  Kind regards
  RAM

  Just to add a little bit to Bob's response.  It is possible for the HA, but as mentioned above, it is not HA as you would expect of a firewall and requires significant network planning and is rather technical in nature.

  The best documentation I could find about the designs HA is in chapter 21 - "Deploying Cisco IPS for high availability" and High Performance of Earworms security CCNP 642-627 official Cert Guide, ISBN: 9780132372107.  She gets quite detailed and explains a large number of different methods.

  I was also able to find some information on this site, but it is at a higher level and does not provide as many options.

  https://www.NetworkWorld.com/community/node/18384

  I had to work HA in some of our environments, and I'm here to tell you, plan ahead, far in advance, test several methods to find one that suits.  We were using a method that I just couldn't find it mentioned anywhere.

• IPS-4240-K9 IDM number 6.2 control events

  Hello world

  I noticed a tangled because of edge idm monitoring events. It does not show alerts, I noticed on the page of welcome home/netwrok security health sensor cyrcle. During the last 5 minutes sensor shows, for example, 10 red alerts, but when I switch on the dashboard of events - there is nothing on this table...

  Several days ago, I saw some periodic alerts on 4003 signature - nmap udp scan. Happening in the course of the week, and I think that quaintity of alerts real tine on the sensor cyrcle of health and on the table of events were the same.

  only that I now note 3041 signature and a few times errorMessage:-store event wrapped autour [IdsEventStore::writeEvent (), index As Integer = 19531] name = errWarning

  I read a few notes about this error, but do not understand what what do I change to display real-time alerts and signature 4003 (when idm is working properly, that it has been the main attack). confoguration virtually all of the default values. IPS works in promiscious mode

  Thanks for any help and advice

  Regarding the message "'errorMessage:-the event rolled around store" "

  The events are stored in a circular buffer. Once the buffer is full, we simply would crush the oldest event. If you see several of these messages, it means that the number of events is really high. You can set frequency of alerts > summary Mode for signatures that shoot a lot.

  Check out the following link to configure the summary Mode:

• do not get traffic of ASA AIP-SSM-20.

  Hello

  We have Cisco ASA 5510, and we recently added Cisco AIP - SSM. We have configured the sensor and did as well as ASA also but we don't get newspapers in ADM please help me on this.

  Please find attached Sersor Configuration and version of the IPS and ASA module.

  Kind regards

  Nathalie. M

  On the SAA, you need

  access-list aip-acl extended deny ip any any
  
  class-map aip-class
  
  match access-list aip-acl
  
  policy-map global_policy
  
  class aip-class
  
    ips inline fail-open
  
  service-policy global_policy global

  so that it sends traffic to the agreement in principle for inspection.

  I hope it helps.

• transparent mode with AIP-SSM-20

  I currently have an ASA5510 routed with AIP-SSM-20 mode.

  It is necessary to use a connection in optical fiber between the ASA and ASA on the campus, so the AIP - SSM will need to be removed and replaced by the SSM - 4GE.  This section should present no problems.

  However, this will remove the IPS device, and I always want to use IPS.

  So what I think is to get another ASA5510, install the AIP - SSM, configure ASA for transparent and put it between the inside of the ASA routed and my local network.  The ASA transparent would be strictly works in the form of an IPS appliance.

  The installation program should look like this:

  Internal LAN <> ASA transparent with IPS <> routed ASA <> WAN

  The AIP - SSM can always perform with the ASA in transparent mode IPS?

  Is it possible to configure the ASA and AIP - SSM such as traffic to and from a particular server completely ignores the AIP - SSM?

  I have a couple of file servers which generate heavy traffic and can overload the AIP - SSM.

  Kind regards.

  AFAIR, it is no installation AIP in a transparent firewall problem.

  "The SAA in transparent mode can execute an agreement in principle.  In the event that the AIP fails,

  the IPS will fail-open and the ASA will continue to pass traffic.
  
  However, if an interface or cable fails, then traffic will stop.  You
  
  would need a failover pair to account for this failure event, which
  
  means another ASA and matching AIP."
  
  

  And no there is no problem to exclude certain hosts/ports/subnets inspection by IPS via MPF.

  http://www.Cisco.com/en/us/docs/security/ASA/asa82/configuration/guide/IPS.html#wp1050744

  What I consider however is however if the ASA 5510 as second level firewall for 5520 s will be enough.
