Prevention of Spam PIX 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.

• Microsoft Security Essentials - how to prevent a spam quarantine

  Dear gentle people

  MSE identified an executable newly installed like a worm.  The alert level has been designated severe. She suspended the action file and recommended the file in quarantine.

  Submit the file to the MS Malware Protection Center showed an eigenstate of detection and commented, it was an incorrect detection.

  However, the only option of MSE gives recommended action is to quarantine the file.  How do you prevent to do now and in the future?

• 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.

• 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

• 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,

• Identification of email as SPAM

  How we prevent mail SPAM OS Mail folder? For me, there seems to be a difference between "Junk" and "SPAM." I have a lot of mail identified as SPAM and is in fact the mail I want. Is there a way to identify an address that is OK to be delivered to your Inbox?

  Also, the JUNK mail folder is not sort the mail correctly. I've tried to sort by Inbox, so I can more easily move mail out of the SPAM folder and they do not sort correctly.

• 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).

  I would need to see your Hijack this log file. Unfortunately, the log files are not allowed on this forum. You can post your question on the forum of free computer on the link below in the Virus/Malware section. You will need to create an account. This prevents the "spamming" and drive - by display. Please do not post the log file until asked to do so by your Assistant. Say your browser is being redirected. You can choose to simply copy and paste your post above and that will be fine.

• 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.

• Notifaction IDS on PIX

  Is there a way to have the PIX send e-mail notice when a certain event occurs, for example an alarm in identifiers.

  No sorry, the PIX does not something like this. It will only send a syslog message when it detects an IDS alert.
