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

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
For more information:
http://www.Cisco.com/en/us/products/ps6076/serv_group_home.html
WARNING: I'm not in the sale so you can check with your local sales office or with a partner of Cisco, Cisco. In fact, some partners may offer a signature subscription service that is clean (without cover material).

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.

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:

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.

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.

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?
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.

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.

Defining a 1852nd Aironet AP - Radio Off - Cisco IOS 12.3 (4) JA
I have a brand new Cisco Aironet 1800 AP series I'm trying to install. Specifically the 1852E. I do not have a controller and try to use the method of deployment of mobility Express. When I received the unit there is a yellow label more precisely declaring outside: "OFF BY DEFAULT note RADIOS: radios are disabled by default for Cisco IOS releases 12.3 (4) JA and later.
If anyone can please tell me how I am supposed to this access point configuration when the radios are not suite, so the CiscoAirProvision SSID is not broadcast?
I tried the following:
1 connect the unit to my PoE switch. Unit Gets power and discovery mode starts (red/orange/green light cycling). He succeeded receives an IP address from my DHCP.
2. when I try to access the device through my laptop via the local LAN it just times out. Pings meet.
I apologize if my post seems harsh, I am quite agitated that even after having spent more than 5 hours trying to troubleshoot and get this thing to work, there was nothing else than a nightmare (both for the installation of touted 10 min). I do RTFM. I missed something simple jumps? or am I just to assume that Cisco has really missed the boat the patch appropriate for an assignment in their literature.
FOR INFO. Thorough searches Google and research on this forum gave me no help.
Thank you.

Hi Bro
Yes, Cisco ASA and Cisco IOS router supported DDNS. Just make sure you have the right version of IOS, which you could refer to this URL of Cisco http://www.cisco.com/en/US/docs/ios/12_3/12_3y/12_3ya8/gt_ddns.html#wp1202953.
Please refer to the config below made with dyndns.org.

Please can someone confirm if the certificate of Cisco IOS server feature is supported on the Cisco 857 router. We have checked with the Software Advisor and no picture for the 857 when the server certificate of IOS feature is selected, but advancedIpservices image v 12.4 (11) T arrives to the 877.
The two 857/877 supports IOS server Certificate
to 857 you need the ADVANCED SECURITY feature set 12.3 (14) YT
877 offers more IOSes with Certificate server supports when I chose the certificate server Cisco IOS feature with featured navigator I got a lot of IOSes supporting this feature
Go to navigator feature
