• IDS fleeing PIX

  How to configure the PIX for IP blocking when my ID detects abnormal activity?

  My version of IDS is 1,0000 S4

  I have a CSPM 2.3.3i version

  You do not really configure the PIX, you just configure the sensor (via CSPM) to block. When the sensor detects a signature that is put in place to block, it will be telnet/SSH for the PIX and add a command to "flee" which will pass all packets from the source of the signature.

  http://www.Cisco.com/univercd/CC/TD/doc/product/ISMG/policy/ver23i/idsguide/CH03.htm#57747

  Noah for a PIX, there is no interface to apply it to, the GET shun applied to all incoming packets on all interfaces.

  You must then change the particular signature so that one of his Actions is to block.

  http://www.Cisco.com/univercd/CC/TD/doc/product/ISMG/policy/ver23i/idsguide/CH05.htm#xtocid263714

  BTW, I would seriously consider upgrading your signatures, you communicated about 25 signatures and 4 service packs behind now.

• Fleeing from a host on the PIX 520 but alerts that are still coming to the IDS

  Last week I saw allot of traffic from a particular host that triggers alerts IDS. After investigating the source, I added a statement SHUN to the pix. When I do a 'sho shun stat' of the NTC for this host is quite high (352) and rises. I still get alerts of the IDS on this particular host (Fragment IP and host sweeps). I guess if I was fleeing from an IP address, I don't receive alerts of IDS on that. Can someone explain what I am doing wrong? Thanks in advance.

  Seems obvious, but can't hurt to ask - where the sniff of your sensor interface? Of course, if your sniffing interface is located outside the pix, then junk traffic will always reach the pix - it just won't be through it.

  In addition, are fleeing this host for these alarms? Doing a show 'show shun' that host being blocked FOR the time you see alerts for this particular host?

• Configure the PIX 501 for IDS

  I have a PIX 501 with wired high-speed LAN headquarters inside and outside. Which would be a solid policy IDS to enable and what interfaces it must be applied to? There will be other measures necessary to enable IDS?

  IDS on the PIX itself is very limited, it checks only 59 signatures listed here (http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_62/cmdref/gl.htm#xtocid9 under the section of signatures supported IDS). The signatures themselves are pretty basic.

  If you do not want to activate this, then for the signatures of attacks I would fix for drop/alarm/reset action, which is the default anyway.

  You will also need to set the logging to a syslog server and monitoring for any 4000nn messages in syslog, cause it event IDS.

• PIX IDS signatures

  Does anyone know the PIX IDS signatures to block Ping scans and Port scans?

  Do the substitution of signatures IDS ACL defined previously? For example; I want to allow people to ping - me (I allowed icmp echo in my ACL), but I want to drop Ping Sweeps and Port scans.

  Gracias.

  PIX IDS signatures are all listed here:

  http://www.Cisco.com/univercd/CC/TD/doc/product/iaabu/PIX/pix_62/syslog/pixemsgs.htm#1032267

  You will notice that it isn't sigs for the port scans and ping sweeps, mainly because it does not detect the PIX. This would imply the PIX to keep track of all the pings or connection attempts and try to understand that if a scanning goes, this is not what the PIX is designed for.

  If you want to see these then a NID system is the best way to go. IDS PIX is very limited and don't look for a very small subset of the signatures, and most of these signatures simply consist of a package, do not try to reconstitute several packages to different hosts or ports.

• PIX: IDS drop allowed vs ACL

  Do the substitution of signatures IDS ACL defined previously?

  If I allowed response echo in my ACL, but I put the ID to drop packets in response to echo, which will make the PIX?

  The ACL or the ID have precedence in PIX?

  DROPS number ID substitute allowed ACL.

• IDS PIX "fat Ping".

  Is it possible to allow ping big answers through the signature of PIX IDS attack without completely turning off the ID?

  Hello

  Use the command 'ip signature verification' to disable this signature

  signature verification IP:

  Specify the message to display, establish a comprehensive policy to a signature and disable or exclude a signature verification.

  I think that the signature is 2151: large ICMP traffic

  Hope this helps,

• How to interpret error PIX IDS

  Hi all

  For example, I got this error: "all ID files: 6053 DNS request.»

  Where can I know exactly what this and other means of ID messages and what are the ramifications of them and if possible corrective measures.

  Peace

  Roy

  The "6053" in this post (and all messages of type ID in the PIX) is the number of signatures. You can check what it means in seeking to network security database (NSDB) here:

  http://www.Cisco.com/cgi-bin/front.x/CSEC/idsAllList.pl

  Note that the PIX does not check for all these signatures, only a small subset of them in fact.

• Prevention of Spam PIX IDS

  Some firewalls (such as raptors) have a function that will check the incoming IP/domain mail to make sure that the domain name of the sender can be reached (reverse) via the IP address of the sender. This prevents spammers from sending mail to your e-mail with falsified addresses server. PIX it? How about you check sending IPs against block lists? It would be cool. And nachos. Nachos are cool, too.

  Nope, is who does not offer the pix.

  IMHO these functions are better achieved at the level of the server e-mail - this way, the e-mail administrators are more fully accountable for the reception and delivery of emails throughout the org and to the ' net, rather than splitting of responsibilities between the security personnel and email admins

• Integration with the PIX IDS firewall

  I read the Release Notes for Cisco Intrusion Detection System Sensor Version 3.0 S4 (1), and tripped on the new features of this version it pretends the integration with the PIX firewall

  How do implement you this? What kind of integration offer?

  Instructions for the sensor and the basic configuration of PIX can be found here:

  http://www.Cisco.com/univercd/CC/TD/doc/product/iaabu/csids/csids8/13870_01.htm#xtocid23

  Instructions for sensor and PIX SSH configuration can be found here:

  http://www.Cisco.com/univercd/CC/TD/doc/product/iaabu/csids/csids8/13870_01.htm#xtocid16

  You can configure the sensor to connect to the PIX via telnet when

  using the PIX inside interface, otherwise you have to use SSH.

  SSH with 3des encryption is supported in version 3.0 or later

  sensors for connections of PIX.

  Warning: If you use telnet with a version 6.2.1 or PIX more late or if

  you want to use SSH with encryption on any PIX, so you

  need a patch for your sensor. If so, open a case of TAC and demand

  the latest version of nr.managed engineering. Reference

• Sharing the burden of the IDS/IPS

  Hi experts,

  Since it is possible to implement some IDS features on routers and PIX, along with the ID is, in a network where all 3 of these devices exist, is it interesting to implement some features on routers and PIX IDS?

  And, if so, what factors are to be considered in deciding what signatures are enabled on what device?

  In this type of scenario, which are considered best practices?

  Thank you very much

  It is possible to do what you ask. Note that the signature on the IPS appliance is a bigger, more complete than other devices together. The exact mix depends on your network configuration. I would say a finer granularity of inspection closer you to your network. For example, the PIX can perform basic firewall functions and filter most of the low-level, floods and general port scans probe. Some routers are good for the limitation of the flow, the traffic shaping, etc. Then the IPS can inspect flows coming into this challenge, focusing on all traffic that could hurt you (beyond knocking on your front door of firewall). Of course, this is just a scenario. Some people can't stand not knowing what to try to knock on the front door. Others do not want the hassle of trying to reconstitute the papers from three different pieces of equipment so they put things in different orders, such as IOS IPS, PIX. Another focus of exploration is what device you can use as a blocking device, the PIX or IOS router (or IP addresses in the case of mode inline operation).

  Cisco means the blueprint of network SECURITY as a job, starting point architecture. The entire library of SECURITY white papers can be found here:

• ID and PIX 515

  I was told that the PIX 515E firewall is capable of BLOCKING malicious attacks as attack Dinal of Service. I learned again by CA engineers that it not are a NO product out there that is able to block attacks but rather notify the administrator only. I'd like your opinion on whether the PIX firewall can actually BLOCK attack or not. Thanks in advance.

  The PIX has some features to prevent DOS attacks, but he can't block everything. For example, if someone launches an attack smurf or something that uses all of your available bandwidth, then the PIX obviously cannot do anything about it because the damage is already done at the time wherever traffic allows you the PIX.

  For something like a TCP SYN attack on a host inside the PIX, then you can configure the static command to allow only a total number of connections through, and/or a number of half-open connections through the internal host, effectively protecting the Server internal. The PIX will refuse further attempts to connect over this limit.

  The PIX also has a built-in limited to IDS. It can detect signatures of 59 common packages and can be configured to block these if they are considered. Signatures that he seeks only are based a package signatures, wide as a real IDS device can get nothing.

  In short, no one can say yes, "The PIX prevents all attacks back", no box cannot do that, because it depends on what the attack back. If someone is flooding your available circuit bandwidth, you really get your ISP involved to block this traffic BEFORE it happens to you. Yes, host-based DOS attacks, the PIX should be able to block most of them with standard configuration controls.

• PIX 501 Logging

  I would like to open a session of hacking and intrusion of the attacks through a PIX 501 with a connection to broadband in a Home Office Setup. I have the camera upwards and the race and I am currently Setup with the Kiwi Syslog Dameon. What would be my best approach Logging all relevant information with the load to the bottom of the unit? Any suggestions / tips would be appreciated.

  Thank you

  It is a common logging configuration that I use:

  opening of session

  timestamp of the record

  logging trap information

  host of logging inside x.x.x.x

  No registration message 106015

  No message logging 106007

  No message logging 105003

  No registration message 105004

  No message recording 309002

  No message logging 305012

  No registration message 305011

  No message logging 303002

  No message logging 111008

  No message logging 302015

  No message recording 302014

  No message logging 302013

  No registration message 304001

  No message logging 111005

  No message logging 609002

  No message recording 609001

  No message logging 302016

  I usually do not enable the logging buffer (never use connection console it will affect performance) because it's not the messages timestamp (it only timestamps in the syslog). But the PIX loaded down with the load, you and Kiwi you before the PIX don't.

  Also turn on the IDs on the PIX.

  It will be useful.

• The system IDS 4215 sensor no IPLogs

  Can someone enlighten me please?

  I have configured a sensor 4215 running the latest version 4 of the software & signatures.

  I have configure the sensor to use a Pix to help fleeing, the configuration worked for more than a week and I chose some to block on signatures and it works and I can see guests in the red list.

  My problem is that under , there is no listed log files,

  Is this correct?

  In version 3 on a 4210 sensor there are several listed log files, these are downloadable on my local machine, where as soon as I could import them in event IDS Viewer and display all events, this is no longer how it's done in version 4?

  What I can do under , is see the list of events that have been posted through the web page of IDM.

  Any help would be greatly appreciated.

  Concerning

  Mark

  First of all, I think that there is some confusion between the IP logs and alarms logs.

  There are 2 types of log files in version 3.x.

  The traditional log file which contained alarms in a comma delimited format that can be imported into VEI.

  The second was an IP trail which was a log of the actual binary packages that have been observed after the signing of fire.

  The action of "log" on the signature would result in the creation of a file of Log of IP and had nothing to do with or no alarm was recorded in the comma-delimited log file.

  Logging of alarms in the comma-delimited log file was controlled by will loggerd has been enabled on the sensor and if loggerd has been installed as a destination for messages in the destination file.

  In version 3.x, you might download individual logs to your own PC files and open them in IEV or load them into your own database.

  In version 4.x is therefore more the concept of individual alarms for files and the log of the IP on the sensor data.

  The alarm logs have been replaced by a circular buffer called eventStore. It can be compared to a large circular database. The eventStore is 4 GB in size and when it is full will begin to overwrite the oldest alarms with the most recent alarms.

  IP logs have been replaced by a similar circular storage for the journal of intellectual property data.

  The data of the alarm in version 4.x cannot be FTP'd the sensor as a diary of the alarm.

  Instead, you have two options:

  (1) use IDM to query the eventstore and pull the alarms that match some criteria. You can then view messages in plain text format.

  (2) use the command "Show events" CLI to do the same thing as IDM can do.

  3) contact Cisco TAC and ask for RDEP specification which provides the syntax for you to create your own queries to plug into the sensor and fire alarms in a raw XML format that you can then load into your own database.

  (4) If you are a user of VEI then the 4.x VEI has the ability to pull older alarms of the probe.

  http://www.Cisco.com/univercd/CC/TD/doc/product/iaabu/csids/csids10/idmiev/swchap6.htm#604023

  In the device properties simply, with the older start time and VEI will automatically extract in these earlier events of the sensor.

  NOTE: It is not a function import that can import plain text or events XML you would see options 1, 2 or 3 above. SO if you want to see in VEI then use option 4.

  Now for iplogs they can be FTP'd to the sensor using the command copy. But iplogs are the binary packet data and not a list of alarms. They are created only when the action of "log" is selected.

  NOTE: IP logging consumes resources sensor and can slow down the performance of the sensor. It is not necessary to IP Log an alarm to see the alarm itself VEI or other management positions. If the action of "journal" that should rarely be used when the binary packet data are necessary.
