• VPN Site-to-Site with IPS Inspection

  Hello friends,

  A simple question:

  Its possible to have IPS inspection (software IPS in the family X, not the SSM module) with the Site to Site VPN environment?

  In other words, can I use firewall with VPN IPS inspection in the same?

  Rafael

  Yes, site to site traffic can be inspected with the IPS module. Only clientless SSL-VPN-traffic cannot be inspected by IPS.

• SETP setp ASA 5505 configuration to inspect traffic

  I have,

  I m strugling with the correct procedure to configure ASA to inspect traffic and only allow traffic any inside out and DMZ.

  Fix my not if necessary:

  1. Configure the interfaces
     • IP address
     • Nameif
     • Security level
  2. Configure the NAT
     • Translation on the inside to the outside
     • Trasnlation from inside the DMZ
     • Static translation from the outside to the DMZ
  3. Create ACLs
     • ACL to allow traffic between the inside and outside
     • ACL to allow traffic from inside the DMZ
     • ACL to form of traffic outside DMZ
  4. Create inspect policy
     1. Class creat card
     2. Create political map
     3. Define type of traffic to be inspected
     4. Associate the policy with the interface

  After that I shoul http ping server and access from outside the network.

  Rigth?

  Hello

  Firstly, the route you created is false. It should be a default route that points to a destination 'ANY' and 'ANY' destination mask. For example, Road outside 0 62.28.190.65 0.

  Second, you don't have politically at the moment because there is a map of default policy already configured with the most important protocols. As a result, ICMP is inspected by default.

  In the third place, to test the traffic between hosts no ICMP routers. Maybe the ISP router blocking an incoming ICMP packets to itself. This means that you will need to create an ACL that applies to the ISP router to allow ICMP to himself. Then, to save all these hassle, just add two hosts as mentioned.

  If you insist on working with routers, do a trace of package for me as shown below:

  entry packet-trace inside 8 0 and post the result.

  Kind regards

• An ASA inspect traffic through a VPN?

  The ASA did inspect the traffic through a VPN using the default inspect the rules?

  Hi Justin,

  The SAA can inspect traffic encryption before or after decryption. The ASA cannot inspect encrypted traffic.

  This means that if the VPN tunnel ends on the ASA, ASA can inspect traffic sent through the prior encryption tunnel and could inspect the traffic post decryption when received.

  If the tunnel is not over on the SAA but pass instead through the ASA, ASA cannot inspect traffic encapsulated inside.

  It will be useful.

• ASA - NG IPS inspect encrypted traffic

  Hello

   
  We buy ASA 5525-X with IPS for us to network. We have a number of servers that provide services Web Applications.
   
  We have a big problem installing ASA it is we cannot use ASA inspect and IPS has because over 80% traffic through encrypted.
   
  Thank you to tell me how I can solve this problem.
   
  I know a solution to use Proxy HTTPS in ASA, but for some reason, this solution cannot be implemented.
   
  Thank you.
   

  If you want to protect you own Web servers against attacks from the internet. You cannot use the HTTPS-decryption of the ASA-CX as the internet - customers do not have your CX-certificate.

  To resolve this problem, the typical is to place a proxy reversed in a DMZ and do the SSL/TLS-manipulation here. The reverse-proxy sends plain HTTP through the ASA and the IPS may inspect what and protect your servers.

• Recording capacity for ASA firewall using ASA-SSM-20 IPS module.

  Hello

  Please could someone give some tips on how to get the ASA-SSM-20 to record information about something like Kiwi Syslog services etc. We just need to get the IPS alerts to generate the SMS/email feature to alert the various intervention teams.

  Thank you

  unfortantely, no syslog support

  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a00807335ca.shtml

  You can configure rules to send snmp traps, and you can pull events using CETS, IPS Manager Express and Cisco.

  If you have logging enabled on the ASA a syslog msg appears when the IPS is asking or blocking traffic.

• Inspect traffic over the policy apply

  Hi people

  I use Virtual Center of 64-bit version 5.3.1.4 defense and I'm trying to understand this option under the access control strategy - Advanced tab. What I try to do, is to allow the loss less than policy changes, at the moment with this option enabled, there are a few seconds interruption of network traffic when the policy is applied. I use inline module of firepower on an ASA5525 by the way. It seems natural that there should be an interruption while the configuration is reloaded on an online service, but the manual is not very clear about the box.

  Someone has a better idea what is this option?

  Concerning

  Hi all

  Let me add in it.

  Power module of fire ASA because of changes in policy or any other reason causing snort recharge. Feature 'feature inspect during the policy applies"does not work for the SAA. The reason behind this is the architectural difference between the devices of firepower (material of the series 7000 and 8000) and modules ASA firepower. In devices, there is a charging wire that supports policy changes without affecting the current treatment of traffic.

  Old behavior (5.4.0.4, 5.4.1.3 and before)

  ASA in rescue mode is based on the heartbeat sensor dplane response to work around the packages. But what snort process restarts due to policy change or driver of any other ground of the sensor responds to the heartbeat ASA and ASA never understands if Snort processes are declining. In this case, ASA continue to send packets to sensor (with Snort down) as well as the packages are removed causing a breakdown of small network size.

  Ill CSCuv91730 (for ASA) and CSCuu68273 (firearms) were introduced to solve this problem.

  New behavior (5.4.0.5, 5.4.1.4 and later versions)

  With the new behaviors introduced ASA will send rescue configuration to sensor backplane header. This information is sent to basic package by the context. ASA expects this sensor to return the package if the flag is set, and even Snort fell. Then, when ASA will receive the same package the snort is down.

  ASA press release fixed side has been published on ORC, but we are still waiting for Sourcefire side fixed (it was fixed, we are waiting for fixed output but I guess a fix is available for this.)

  Thank you

• 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:

  IPS - K9 - 6.1 - 1 - E1.pkg

• SSM, Cisco IPS Manager, IPS version 1.0000 E2 module

  When in the EPI manager and I try to make a change to the pilices, I get the following error.

  Failed to retrieve the configuration information for the sensor

  No idea what causes this error.

  Kind regards

  Dan

  Dan-

  If your "IPS" Manager CSM, you should check you have connectivity between the server and the sensor and your CSM is a host that is allowed on the sensor (one day our CSM decided to erase a lot of list of hosts allowed our sensor, how fun).

  You can re-import your sensor in CSM, or I have deleted much troubling problems to simply remove the sensor to the CSM and adding them as new.

• SSM - IPS 6.03E1 unwanted blocking

  Hi all

  I do some tests in the laboratory and came across something that is interesting to me:

  I activated sigs 2000 and 2004 to test that the ips inspects traffic and checked the action for these 2 sigs as producealert only. Worked well with sev alert information. However, when the TES to quick raisng SPI begins to block icmp packets, even though the action related to the signature is produced alert. Why the IPS blocks this traffic? I'm missing something here. As always, help is appreciated.

  There is a default event-action-override for deny-package-inline that is added to all events with a side of risk of 90 or higher.

  When you run the Setup program on the sensor, one of the last questions is "parameters of prevention threatens to change by default? [None] ».

  If you answer 'no', then the default value remains active. Your signatures of 2000 and 2004 will generate a risk score greater than 90 if you change high gravity and therefore will be automatically denied.

  If you answer "Yes" then you are provided the option to disable these default settings.

  For this configuration option see step 20 of this article:

  http://www.Cisco.com/en/us/docs/security/IPS/6.2/configuration/guide/CLI/cli_initializing.html#wp1072155

• Inspection of traffic between hair-pinning VPN on a SAA with AIP SSM.

  Hello

  I want to deploy an ASA as a VPN endpoint and to use the AIP SSM module to inspect and provide protection for inbound traffic arriving on a VPN and start on another within the same ASA. I guess it's possible because traffic is unencrypted in the ASA State and must be intercepted by the class plan. Anyone who has done this or can anyone confirm that this will work?

  Thank you very much

  Wil Bowes

  If the ASA finishes the VPN, then indeed it can also inspect internally. The decryption happens before "module controls" for inbound traffic and the arrival of "control module" before encryption for outgoing traffic. If you can do it.

  I hope it helps.

• ASA-SSM-10 inspection load 100% (version 7.0 (5 a) E4)

  Hi all

  I have a challenge with the IPS module in ASA5520, ASA-SSM-10. When we start a try to connect to Web servers, I get a load of 100% inspection and will slow down the traffic/performance.

  We test with 63000 sessions per minute making a load of: the test-servers (clients) on the web servers of 20,000 Kbps and traffic from servers web-back to the test-servers (clients) 75.000 kbits/sec.

  Can you please advise what to do because we cannot live with this environment only when this is fixed.

  Thanks in advance,

  Erik Verkerk.

  We have not used charge of inspection in order to determine the appropriate sensor performance, instead, we have relied on "percentage of failed package" reported by the sensor. When the sensor gets into trouble, that they will begin to run out of packets for inspection, this causes the sensor wrong determination of the TCP State for some of the connections. This causes the sensor to use more resources than necessary to inspect traffic, leading to lack more packages.

  It is its called the "death spiral" and we try to avoid it as much as possible.

  Cisco has a long and proud history of providing performance numbers 'blue sky' for their products. We used to refresh their numbers of performance of the IPS sensor by half, but they made improvements over the years and now we take only about 1/3 wide of reported values. You can see for yourself with real, live production traffic.

  I'm havn; t found the number of signatures in a meaningful way sensor effect performance unless you touch abnormally difficult or lit a large number or tuned to perform many actions per second.

• Probes IPS from multicast traffic

  The ASA/AIP-SSM modules pass multicast traffic when it is configured in online mode?

  -Bob

  Hi Bob,

  The AIP - SSM acts as a L2 bridge when it is used in Inline mode, so it must pass very well multicast traffic.

  I did some research, and unfortunately, there is a bug that would prevent do this according to me:

  CSCtb82257  Multicast sending to the AIP - SSM module affects Dimethylacetamide 0000.0000.0000

  Since it is not fixed yet, I advise you to have multicast traffic circumvent the AIP - SSM and send unicast traffic to it.

  Kind regards

• Update license of IPS ASA - SSM

  Hello

  We have an ASA-SSM-20 IPS, the license has expired and we purchased a Smartnet contract for the device.

  I would like to know how to upgrade the license.

  We tried to do the ASDM, and chose the option updates to cisco.com.we got the following error.

  internal error. Unable to send the license request. -4: unable to proxy transparent tunnel. Proxy returns "HTTP/1.1 403 Forbidden.

  How to solve this problem or how to do when you use the other option, how to get the license file.

  Best regards

  It seems that your AIP-SSM20 is configured to use an http proxy to connect to the Internet. If you allow the IP address of the AIP-SSM20 management in your web proxy, it may solve your problem.

  If this isn't the issue, you can always apply a license manually. Download your license file here:

  https://Tools.Cisco.com/swift/LicensingUI/home

  and apply via the ASDM or the CLI

• What are different between the IPS and AIP - SSC and AIP - SSM?

  Dear all,

  I'm not clear about the IPS, AIP - SSC and AIP - SSM module which are different?

  Then, when we can use IP addresses?

  When we use the AIP - SSC?

  When we can use AIP - SSM?

  Thus, a different IPS and AIP - SSC and AIP - SSM material or the same material?

  Best regards

  Rechard

  AIP - SSM is an IPS Firewall ASA module.

  IPS is available in different flavors:

  -Device of the IPS 4200 series

  AIP - SSM - module IPS Firewall ASA

  -IDSM2 - IPS module on 6500 series switch

  AIM - IPS - map IPS on router IOS
