How ASA forwarding traffic to AIP-SSM

Hi All,
Can someone help how ASA device forwarding traffic to AIP-SSM? I'm not taking abt Configuration part like Class-map, policy-map and service policy....want to understand the traffic flow from ASA once traffic matched with ACL to AIP-SSM.
From one of Cisoc document, understood that the module using a Cisco Propietary protocol for communicating with ASA appliance.
================================================================================================================
FYR from Cisco Website:
Q. How does the Cisco ASA AIP-SSM plug into and communicate with the appliance?
A. The Cisco ASA AIP-SSM plugs directly into the SSM slot in the Cisco ASA appliance's chassis. This provides a direct connection to the appliance's backplane. Once the module is installed, a proprietary protocol runs over the bus and controls data flow and messaging between the module and appliance.
================================================================================================================

Hey ,
as you mentioned above , it uses a cisco Probietary protocol for that communication , there are two interfaces , control channel and data channnel , data channel is where the traffic being forwarded , the backplane is the connection between the ASA and the IPS interface .
Hope that this helps .
Mohammad.

  • How to generate license for AIP-SSM without PAK-number?

    Hello! I’m sorry for my English. I have a problem with generating license for AIP-SSM. My contract with SMARTnet service is activated, but I don’t have a PAK-number. How I can generate a license for updating my module?

    Alternatively you can always write an email to [email protected] with your serial number and they should be able to provide you the license for any cisco device.

  • Do any ASA Inspect statements overlap AIP-SSM functionality?

    Are the ASA inspect statements (http,ftp, sunrpc, etc) a duplication of functionality available in the AIP-SSM IPS module? Asked another way, can/should any of the inspect statements be turned off when the AIP-SSM is present?

  • ASA failover with 1 AIP SSM in Active/Standby?

    I have a customer with two ASAs; in Active/Standby. They want to purchase one AIP. Will failover (without the AIP functionality) to the Standby work if the AIP is configured for Promiscuous mode? Thanks, Bob

    The only connection to the SSM that can be done internally through the ASA is a "session". This is an internal telnet to the SSM and can be used to access the SSM's CLI.
    This is very usefull when you manage your SSM directly through the CLI.
    However, most customers prefer to use a graphics based tool like IDM, ASDM, or CSM for managing the configuration of the SSM, and prefer to use a graphics based tool like IEV or CS MARS for monitoring of the alerts from the SSM.
    All of these graphics based tools need network access to the SSM through a web port (https on port 443 by default). Access to this port is not allowed internally through the ASA direct to the SSM.
    All web connections must be made to the External Management interface of the SSM.
    If you are not using all 4 of your ASA interfaces you could choose to wire the External SSM interface directly to one of your ASA interfaces, and create a small subnet for the ASA and IPS IP Addresses. So then all external connections to the SSM would be routed into the ASA, then out of the ASA, and into the external port of the SSM.
    That subnet of just the ASA and SSM could be made using a network reserved for local IPs (like a 10, or 172, or 192 network) and then use NAT/PAT for translation on the other network interfaces of the ASA.
    But it does still require that wire connected to the external port of the SSM.

  • How do I forward traffic to an IP Address from a gateway through an extreme?

    I have a DVR for a Camera system attached to a WiFi Ethernet device (becuase there is too far a distance between the DVR and Cable Gateway). When it was attached directly attached to the cable modem, I used Port Forwarding to route traffic to the DVR. That worked great. NOW I have to use the WiFi adapter and that is connecting to the Airport Extreme. The Aiport Extreme is connected to that cable modem.
    So I understand how to forward traffic from the modem to an IP address (the Extreme's IP perhaps ??) but then how do I send that traffic through the Extreme to the wifi-ethernet adapter connected to the DVR ?

    I am on my mobile phone getting an address of 10...83 through the router 10...1.
    Then the DVR setup on 10...69 IS accessible.
    When I switch my wifi off (on the mobile phone)  and I use the ip address (23…94) of the modem w/ port specification I do not get connected.
    When I plug DIRECTLY into the Cable Modem and get an IP address of 10…53, via (Mac OS X) I CAN access the DVR again with ip of 10…69.
    When I use WIFI (via the AE) I get an IP Address of 10…44 and CAN access the DVR as well.
    I have also confirmed traffic is port forwarding to .69:7000 as per the port specified on the DVR.
    So with all that it is confirmed, I tried it again and and still not working...
    THEN I reset the AE, Resset the Wifi Adapter, Reset the DVR and updated Firmwares, started with the basics outline from everyone and IT'S WORKING!!
    I believe it was actually all the AE and requiring a reset on that device.
    Thank you again for all the help, this was a fun challenge!

  • Transparent mode with AIP-SSM-20

    I currently have an ASA5510 in routed mode with an AIP-SSM-20.
    There is a requirement to use a fibre optic connection between this ASA and another ASA across campus, so the AIP-SSM will have to be removed and replaced with the SSM-4GE.  This part should present no issue.
    However, this will remove the IPS device, and I still want to use IPS.
    So, what I am thinking is to get another ASA5510, install the AIP-SSM, configure ASA for transparent mode and put it in between the inside of the routed ASA and my LAN.  The transparent ASA would be functioning strictly as an IPS appliance.
    Setup would look something like this:
    Internal LAN <> transparent ASA with IPS <> routed ASA <> WAN
    Can the AIP-SSM still perform IPS with the ASA in transparent mode?
    Is there a way to configure the ASA and AIP-SSM such that traffic to/from a particular server completely bypasses the AIP-SSM?
    I have a couple of fileservers that generate heavy traffic and could overload the AIP-SSM.
    Regards.

    AFAIR, There is no problem to setup AIP in a transparent firewall.
    "An ASA in transparent mode can run an AIP.  In the event 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 from inspection by IPS via MPF.
    http://www.cisco.com/en/US/docs/security/asa/asa82/configuration/guide/ips.html#wp1050744
    What I however consider however is if the ASAs 5510 as second tier firewall for 5520s will be enough.

    Hi,
    CON-SU1-AS2A10K9 contract if for ASA+IPS bundle. If AIP-SSM-10 ws purchased as a spare the contract would be CON-SU1-ASIP10K9.
    I am not sure whether or not this Cisco Service for IPS contract can be  used to cover just the AIP-SSM-10 if it was purchased as part of a  Bundle instead of a Spare.
    I would recommend that you check with your Cisco reseller or Cisco  Sales Representative.

  • Best practices for using Normalizer in ASA and in AIP-SSM

    Both PIX OS 7.x and IPS 5.x software have a concept of "traffic normalization". PIX OS on ASA can do virtual reassembly, IPS on SSM (so far as I know) can do physical reassembly and fragmentation of IP packets. Also, both ASA and SSM can do TCP normalization. For example, they both can "check inconsistent retransmissions" and protect against "TTL evasion attacks". I realize that PIX OS has only basic normalization functions and the SSM is much more configurable.
    The question is: what are the best practices here? Is it better to disable some IP/TCP PIX OS checks / IPS signatures on ASA and/or SSM? Is it better to use just SSM for traffic normalization? Does anybody has personal experience here?
    Also, there is a BugID CSCsd04327 - "ASA all out of order packets are dropped when sending to ssm"
    "When ips ssm is inline slowness is reported. show service-policy shows that the number of out of order packets reported match exactly the number of no buffer drops (even with queue-limit option). Performance hit is not the result of tcp normalization (on IPS 5.x ssm) in this case, but rather an issue with asa normalizer."
    To me it seems to be more logical to have normalization function on the firewall, but there may be drawbacks in doing this.
    So, those who're using ASA with SSM, please share your experience.
    Thx.

    Yes, this is almost correct ;)
    TCP SRP (Stream Reassemly Processor) is turned OFF on the SSM and cannot be enabled, contrary to 4200 appliances, but IP FRP (Fragmentation Reassembly Processor) is functioning on the SSM.
    The testing of 7.2(1) shows the following:
    When you configure "policy-map" to send packets to the SSM the "tcp-map" parameter "queue-limit", which has the value of zero by default, is set to an X (the X is unknown). This means that the ASA now only accepts the TCP segments which are sent in the correct order. More specifically, the gaps in SEQs are not allowed anymore. When for example, the ASA receives a TCP segment which has a SEQ within the window, but the previous TCP segment has been lost, it sends an ACK to the sender to enforce retransmition of the lost segment. As a result the sender retransmits both segments. Only after that the ASA forwards both segments to the SSM. This basically means that SSM always sees in-order TCP segments. That it is why SRP is not needed on the SSM.
    There are at least two problems however.
    The first problem is the performance impact.
    ASA now acts almost like a proxy. And, so far as I know, it doesn't support SACK (Selective ACKs). First, when the ASA does TCP SEQ randomization it doesn't change SEQ values within the SACK TCP Option. This simply breakes SACK. Second, even if you turn randomization mechanism OFF, then, I believe, the ASA will not selectively ACK the lost TCP segments, as it simply doesn't support this mechanism.
    The second problem is THE SECURITY HOLE.
    By default the ASA doesn't check TCP checksums. The 4200 appliances do check by default. But as we now know the SRP is turned OFF on the SSM... So, this means that SSM module can easily be evaded. The hacker only needs to mix attacking traffic with the random TCP segments that have bad TCP checksum. The SSM module will see the mixture of the two and will not recognize the attack. The target host will drop TCP segments with the bad checksums and see only attacking traffic... This has been successfully verified in the lab.
    Of course, this security hole can be closed with the "tcp-map" parameter "checksum-verification", but it will definitely has performance impact.
    The last note: All of the above has never been documented by Cisco. So, use at your own risk, etc.
    I hope, you will read this message, Marcoa. All of this MUST be documented. Once again, the default behaviour of the ASA opens up a big security hole.

  • AIP-SSM, it is not sensing the traffic

    Hi everyone, i have a trouble, now iam using an ASA 5510 with AIP-SSM10, my problem is when I redirect the traffic to the AIP-SSM for detects attacks, i probe it and then I look in the events logs of the IPS, and the sensor dont detect nothing, is necessary to install an IPS license??, it is for my own project, thanks.

    Unless you are scanning across the ASA, the SSM module will not "see" the scan and cannot produce events. To alarm on an SSM module, you must scan from one network to another. Basically, the SSM cannot do promiscuous monitoring. I would recommend an IPS appliance if you want to monitor traffic sent between hosts of the same network.
    ** Pls rate if this helps **

  • Cisco IPS 4240 VS Cisco ASA AIP SSM-10 Modula

    I'm looking to replace another vendor's IPS system we have at our company. We do have an ASA 5510 in our envionment currently.
    Considering I don't need the extra bandwidth of the IPS 4240 series and the AIP SSM-10 requires an ASA 5510 what are the differences?

    Operationally the AIP-SSM1 and the 4240 run the same software, so they work pretty much the same.
    The AIP-SSM inside the ASA is less expensive alternateive, but becuase it sits inside an ASA there is more to configure and manage (the ASA plus the sensor), The ASA also has some built in inspections that may filter some traffic/attacks from being seen at the AIP-SSM sensor.

    Hi,
    How to block p2p application using AIP-SSM-10 working with ASA5520?AIP is on promiscuous mode.
    Thanks,
    Siva

    There are several signatures that detect p2p, for bit torrent there is 11020.0
    Yahoo triggers: 5539.0, 11200.0, 11212.0, 11217.0 & 11219.0
    etc..
    Some are disabled by default though so please ensure you enable the ones that you need.
    If you want to block these then you will have to use event actions that work in promiscuous setup for example request block connection and tcp reset. Please note that care must be taken when using these event actions.
    For more information about the event actions please refer the link below:
