• Had a bad IPS SSM-20 RMA for the nine now license need to fire?

  Now the license for IP addresses on my account service contract is different than the one installed. the serial numbers are different? How can I get the I went back through RMA and have a license for the new serial number?

  Use your open box of TAC to request the license is transferred. It should have been done automatically when the device has been RMA'ed, but if not just ask your TAC engineer to do.

  We need to block access of host say 64.15.152.208

  Just need the best step to follow and block access, without affecting the service or other host

  Thank you

  Insert a line like:

  OUTSIDE-IN-ACL scope access list deny host ip 64.15.152.208 all

  in front of your 3rd line "... to enable icmp a whole."

  If you have many of them, maybe do:

  object-group network blacklist

  host of the object-Network 64.15.152.208

  network-host another.bad.ip.here object

  object-network entire.dubious.subnet.here 255.255.255.0

  ...

  OUTSIDE-IN-ACL scope object-group BLACKLIST ip deny access list all

  If you want to take in scores of reputation on the outside, or the blacklist changes a lot, you might look into the Cisco ASA IPS module.

  Note that fleeing bad hosts help with targeted attacks, but not with denial of service; only, he moves to point decline since the application for the firewall server, without much effect on the net on your uplink bandwidth consumption.

• WRT610N dhcp gives wrong IP addresses all the time (on a wired connection only)

  Hello

  We use a 10.0.0.0/24 subnet for our router. The router is 10.0.0.1 and is configured to assign IP addresses from de.200. Now, while this does very well on the wireless, we get always bad IPs (of the 192.168.1 subnet) when you use a wired connection.

  The problem disappeared after only a factory resets, but now reappears. Customers are different from linux clients.

  Is the firmware bug?

  Arnuschky

  Most likely, someone else on another router your network that assigns 192.168.1 addresses.

  Do the on two computers once with a 10 addresses assigned, once with a address affected 192.168.

  Open a window prompt on your computer. Type ' ipconfig/all '. Then ping the default gateway, for example "ping 192.168.1.1" or "ping 10.0.0.1. Then enter 'arp - a'. After the output is full in each case.

  This should show how computers are configured, how and where they get their IP and MAC address of the router/DHCP server.

• IPS blocking fleeing and deny Inline

  I recently moved from inline promiscuity and want to enjoy refuse packages inline. With "Promiscuous" mode, I added my local networks to the block list ever. Do the never apply the inline options to reject blocked packets? If not is there another list to wait or should I write an event filter?

  The block list applies only to the blocks are made on other devices (routers, switches, firewalls).

  To avoid denying it to the same addresses, you must use event Action filters. Create a filter to the same addresses as source/aggressor, for all transmissions, subsigs, dest addresses, ports, etc. and select actions event deny attacking Inline, refuse the Service forward pair Inline and refuse the perpetrator victim pair Inline like stocks to avoid.

  By subtracting these actions will ensure that the inline sensor is not blocked long term based on the address.

  You can decide whether to add deny it the package line and deny it online connection to this filter as well.

  I do NOT recommend adding them so you can't deny the specific packets/connections used an attack even when this attack originates inside your network.

  Also understand that the filter will prevent only to deny the striker... Online actions done automatically by the outbreak of a signature. It will NOT prevent these addresses to refuse if someone manually enters an address on refuse through the CLI. (CLI entered Denies were introduced in IPS 6.1) (NOTE: I don't remember if IDM/IME support adding denies manually)

• IPS sensor - Event Notification by e-mail?

  Good day to all.

  I was asked to recreate some features after he lost the customer improved VMS to the CSM but without CS-MARCH or any other event monitor. The user has had the system to generate an email when an event was triggered. He was apparently noisy initially but after setting wasn't a bad solution. No one knows how he was initially put in place but I can only assume it is the method that is described in the Cisco document to: http://www.cisco.com/en/US/customer/products/hw/vpndevc/ps4077/products_configuration_example09186a00801fc770.shtml#fivesensor

  Now, however, since the CSM has not received the event data is it possible to recreate this process of "notification"?

  Are using CSM 3.02 and the sensors are still at 5.14. The sensors will be updated to 5.17 later today. I will then either be upgrading the client to the latest revisions and service to CSM or rolling packs to the VMS depending on whether I can get notifications to work with MSC.

  NOTE: They order a CS-MARS appliance with the conviction that it will solve the problem, but as the last word, it will be several months at least before they could get it. I'm afraid that CS-MARS will NOT give back them this feature. Can you confirm/deny?

  Finally - CSM does not include a security monitor, as did virtual machines, and CS-MARS not really recreate that kind of view or the management of the events - what solutions are there to reproduce the functionality of the Security Monitor? Are there? Is-CS-MARS the new bully on the block?

  Since the client is to stay at a 5.1 version, then you have 3 options:

  1) down to virtual machines and continue to use the Security Monitor

  2) stay with the CSM and buy CS-MARCH for the monitoring of events. CS-MARS should provide the ability to e-mail notification.

  3) stay with the CSM and installing and using VEI 5.2 (1).

  VEI 5.2 (1) can be installed either on a separate machine from the CSM as a stand-alone utility:

  http://www.Cisco.com/cgi-bin/tablebuild.pl/IPS-EV

  VEI 5.2 (1) contains the new alerts e-mail notification feature.

  GOLD VEI 5.2 (1) can be installed as part of the installation of CSM (I know it's in the CSM 3.1, but don't know about previous versions of CSM).

  Here are a few documents on the execution of the IEV 5.2 (1) in the CSM framework:

  http://www.Cisco.com/en/us/partner/docs/security/security_management/cisco_security_manager/security_manager/3.1/user/guide/monidiag.html#wp1203768

  NOTE: VEI 5.2 (1) is targeted for use in networks with sensors of 5 or less. When running with 5 sensors or more, then CS-MARS would be the veiwer advised.

  When the user later upgraded to version 6.x, then option 1 (downgrading to virtual machines) is no longer an option and option 2 or 3 would be required.

• How to cancel the encryption SSL on ACE after scan IPS

  Hello

  A query on the SSL termination. This is the logical path,

  The traffic encrypted hits the router-> hits the ASA IPS-> and then hits the VIP for balancing by ACE.

  Encrypted SSL traffic must end on ACE load balancing. However, the IPS analysis cannot be performed on a decrypted traffic.

  How can we re - encrypt traffic to complete on the load balancer. Or is it a bad idea because of performance issues?

  Kind regards.

  Yes, your understanding is on-site. Both IPS/CSC need traffic decrypted to do something meaningful.

• Error when you try to move the SSM to IPS 6.1

  I am running 4,0000 E1 and when I try to upgrade, it says "can't upgrade the software on the sensor. This package cannot be installed on the platform of the SSM-IPS10. »

  I tried upgrading via IDM, FTP, SCP, and I get the same error.

  I'm trying to upgrade using the package IPS-AIM-K9-6.1-1-E1.

  Simple problem to use the file of E1 6.1 (1) bad.

  The IPS-AIM-K9-6.1-1-E1.pkg file is specific to the AIM - IPS module for ISR routers.

  AIM - IPS module for ISR routers must not to be confused with the ASA-AIP-SSM modules for devices of the SAA.

  All other platforms (including the SSMs) should use the standard 6.1 (1) E1 file upgrade:

• Virtual sensors IPS

  Hello

  1. can I use the sensor default virtual vs0 for incoming traffic on all interfaces.

  2. How can I assign interfaces to the AIP - SSM module.

  3. How can I assign interafces to the JOINT module.

  I'm assuming that the assigned interfaces are those on which inline inspection is carried out.

  The AIP - SSM is not "both" of these modes. This applies only to sensors/JOINT AFAIK.

  The AIP is inwardly 'connected' to the ASA and has only two modes of deployment instead of three, here is a brief description of EAC:

  #Is the AIP - SSM module to operate or be deployed in inline mode or promiscuous?

  * "Promiscuous" mode means that data is copied to the AIP - SSM while ASA passes the original data to the destination. The AIP - SSM in promiscuous mode can be considered an intrusion (IDS) detection system. In this mode, the trigger package (the package that causes the alarm) can still reach the destination. Fleeing can take place and stop the extra packages to reach the destination, but the triggering packet is not stopped.

  * Mode Inline means that the ASA transmits data to the AIP - SSM for inspection. If the data meets the AIP - SSM inspection requirements, data refers to the ASA in order to continue to be processed and sent to the destination. The AIP - SSM mode inline can be considered as a system of prevention of intrusion (IPS). Unlike promiscuous mode, mode inline (IPS) can actually stop the trigger packet to reach the destination.

  the file being attempted to install isn't what they expected the ROMMON of the MSS.

  The Image file of the system was damaged during the download.

  OR the attempt of the procedure of the System Image with one file other than a System Image.

  There are several types of files for IPS and their use is often confused.

  For example:

  For version 2.0000 E3, there were 3 different files for the AIP-SSM-10:

  The system image:

  IPS-SSM_10-K9-sys-1.1-a-6.1-2-E3.img

  -For installation through ROMMON or more technically the "module hw-module 1 recover...» "order of the SAA. Install a complete Image of the system on the MSS and erases all previous data from the SSM.

  NOTE: This is the type of file to be used in the method you follow.

  Update:

  IPS - K9 - 6.1 - 2 - E3.pkg

  -To upgrade from an earlier version of the sensor to this new version. It converts the previous configuration to work with the new version.

  Recovery partition:

  IPS-K9-r-1.1-a-6.1-2-E3.pkg

  -For the upgrade JUST the SSM recovery partition. The recovery partition can be used for recovery with the "application-recovery partition" command in the sensor CLI.

  There may be some confusion here, because this file is the 'Recovery' image, BUT is NOT used with the command "recover the hw-module module 1" of the SAA.

  Instead, the Image of the 'system' is what is used with the command "recover the hw-module module 1.

  If you find that you do not use the correct file type (unkowingly used a upgrade or recovery file), then download the System Image file and try again.

  If you use the System Image file, then check the size and md5 checksum of the file and compare it to what is on cisco.com. It was damaged during the download from cisco.com and you may need a new download of the file.

  If the checksum md5 and size of the file is the file on cisco.com, check your TFTP server. Using a 3rd attempt of machine for the file from the tftp server tftp. Once the tftp would check the size and md5 checksum to verify that your TFTP server is able to serve the entire file. You want to make sure your TFTP server is not truncate your file for download.

  Hi Alex,

  Matthew has been mentioned previously, for the NME module, the access list defines which traffic will be NOT be inspected.

  If you want the NME to inspect all traffic, you need to change the list of access to DENY all traffic.

  So, change it to "access-list 100 deny ip any one" to inspect all traffic.

  Thank you
