• How to monitor connections dropped and rejected on the PIX Firewall / ASA?

  I need to monitor the SNMP OID of the connections dropped and rejected on the PIX and ASA firewalls. Is this possible?

  If this is the case, what SNMP OID should I monitor?

  Syslogs and Netflow (introduced in version 8.2) are your options.

  No MIB can give you the numbers of conn.

• PIX firewall Security Guide

  Hi guys, I noticed that there is a document on the setting of the Cisco routers on cisco.com

  Is there than a best practices similar document type for Secure PIX firewall? or even a general firewall best practices guides?

  I searched, but did not really find anything. Any help would be great!

  Hi Nathan,

  So far, there is no specific doc, but you can get the idea of documentation PIX / ASA itself. This is probably due to the nature 'trust' of the firewall itself (everybody knows that it was not 100% sure).

  Anyway, there is a document on "Best practices of firewall" at http://www.principlelogic.com.

  Others are:

  http://www.Security.FSU.edu/firewall.cfm

  http://SearchSecurity.TechTarget.com/originalContent/0, 289142, sid14_gci838230, 00.html

  Personally, I think the recommendations are very good and can be applied generally to fix most of the firewall products.

  I hope this helps.

• Access list ID # on a PIX firewall

  Is anyone know what of the identifier access list on a pix firewall?

  Standard IOS = 1-99

  Extended IOS is 100-199.

  SW = PIX?

  There is no "limit" by Word to say in the Pix. These limits are in IOS because they define what 'type' of acl, it's IE APPLETALK, IPX, IP etc etc. Pix IP is therefore not necessary for this type of identification.

  access-list 100000000000000; 1 items

  allow line of the access list 1 100000000000000 ip any a (hitcnt = 0)

• PIX and ASA static, dynamic and RA VPN does not

  Hello

  I am facing a very interesting problem between a PIX 515 and an ASA 5510.

  The PIX is in HQ and has several dynamic VPN connections (around 130) and IPsec vpn remote works very well. I had to add a PIX to ASA L2L VPN static and it does not work as it is supposed to be. The ASA 5510, at the remote end, connects and rest for a small period of time, however, all other VPN connections stop working.

  The most interesting thing is that ASA is associated with the dynamic map and not the static map that I created (check by sh crypto ipsec his counterpart x.x.x.x). However, if I make any changes in the ACL 'ACL-Remote' it affects the tunnel between the PIX and ASA.

  Someone saw something like that?

  Here is more detailed information:

  HQ - IOS 8.0 (3) - PIX 515

  ASA 5510 - IOS 7.2 (3) - remote provider

  Several Huawei and Cisco routers dynamically connected via ADSL

  Several users remote access IPsec

  A VPN site-to site static between PIX and ASA - does not.

  Here is the config on the PIX:

  Crypto ipsec transform-set ESP-3DES-ESP-SHA-HMAC-IPSec esp-3des esp-sha-hmac

  Dyn - VPN game 100 Dynamics-card crypto transform-set ESP-3DES-ESP-SHA-HMAC-IPSec

  The problem is that the ASA has a crypto acl defined between host and network, while the remote end has to the network.

  Make sure that the acl is reversed.

• How to limit the ICMP on the PIX firewall.

  Guys good day!

  I have a dilemma with regard to limiting ICMP users browsing to other networks such as other demilitarized interns.

  I know that, to allow ICMP to pass through interfaces, you will need to create an ACL such as below:

  access-list DMZACL allow icmp a whole

  Users require this config ping a server on the DMZ, but it is a security risk.

  To minimize, I have a group of objects created in order to identify hosts and networks is allowed to have access to the echo-replies.

  Again, this is a problem since many host who extended pings just to monitor the connectivity server and its application.

  Do you have other ideas guys?

  As to limiting the echo answers on the PIX. As first 5 echo request succeed with 5 echo-replies and the rest would be removed.

  This could be done?

  Thank you

  Chris

  Hello.. I don't think you can do this by using an ACL on the PIX, however, you might be able to stop the ICMP sweeps by activating CODES signatures using the check ip command you... For more information see the link below

  Guidelines of use Cisco Intrusion Detection System (IDS Cisco) provides the following for IP-based systems:

  ? Audit of traffic. The application of signatures will be audited only as part of an active session.

  ? Apply to the verification of an interface.

  ? Supports different auditing policies. Traffic that matches a signature triggers a range of configurable

  actions.

  ? Disables signature verification.

  ? Always turns the shares of a class of signature and allows IDS (information, attack).

  The audit is performed by looking at IP packets to their arrival at an input interface, if a packet triggers

  a signature and the action configured does not have the package, and then the same package may trigger another

  signatures.

  Firewall PIX supports inbound and outbound audit.

  For a complete list signatures of Cisco IDS supported, their wording and whether they are attacking or

  informational messages, see Messages in Log System Cisco PIX Firewall.

  See the User Guide for the Cisco Secure Intrusion Detection System Version 2.2.1 for more information

  on each signature. You can view the? NSDB and Signatures? Chapter of this guide at the following

• Why did after downloading Windows security updates that Windows Firewall starts immediately after opening?

  Why did after downloading Windows security updates that Windows Firewall starts immediately after the connection?   This is happening with my PC and netbook, I almost hesitate to download the safety of dates in the future

  Hello

  1. What is the security update article?
  2. are there any other security software installed on your computer?

  If you have any third-party security software installed on your computer, I suggest you to disable the security software and then check if it helps.

  Note : If you need to temporarily disable the security software, you should reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks

• Cisco ACS and Pix Firewall

  I have configured the aaa authentication in the pix firewall to see the ACS RADIUS Server for verification of the user. If the ACS server becomes unavailable, then I could not connet the pix firewall.

  In the router, I have the configuration option

  AAA authentication login default group Ganymede + local

  that tells the router first looking for a radius server and if is not available connect through the local database.

  Is there an option in the Cisco pix firewall to connect using local information if ACS is not available?

  Thanks in advance

  Hello

  PIX back up method to entered the unit in the event of server failure aaa works on 6.3.4 code and above. In the codes plus late 6.3.4 If the RADIUS server fails it is impossible to get in unless password recovery. "However if we have not configured for console aaa authentication than user name: pix and password: cisco" works by default.

• PIX firewall problem

  I have two servers, one in pix inside and the other in the demilitarized zone. I wanted to set them up so that they can communicate with routers and switches

  Located outside the pix firewall.

  My inner Server works fine, able to go Internet and able to comminicate with all devices located outside the Pix Firewall. Here is reference configuration

  of insideserver.

  outside_acl list extended access allowed host x.223.188.0 255.255.255.0 172.28.32.50 ip

  outside_acl list extended access permit ip host host x.219.212.217 172.28.32.50

  access-list extended sheep permit ip host 172.28.32.50 host x.219.212.217

  access-list extended sheep permit ip host 172.28.32.50 x.223.188.0 255.255.255.0

  inside_acl list extended access permit ip host 172.28.32.50 all

  But my DMZ server does not work. However, I made the same configuration with respect to the server on the inside. Not able to communicate with outside DMZ server

  network.

  outside_acl list extended access allowed host x.223.188.0 255.255.255.0 172.28.92.72 ip

  outside_acl list extended access permit ip host host x.219.212.217 172.28.92.72

  dmz_acl list extended access permit ip host 172.28.92.72 all

  If I create a static entry for your DMZ SNMP server.

  static (edn, external) 172.28.92.72 172.28.92.72 netmask 255.255.255.255

  He starts to communicate with external devices, but stops Internet run on this server. same configuration

  works with the server on the inside, but not with dmz server.

  NAT (inside) 0 access-list sheep

  NAT (inside) 3 172.28.32.0 255.255.255.0

  NAT (dmz) 3 172.28.92.0 255.255.255.0

  Global interface 3 (external)

  Your static entry is bypassing your nat (dmz) 3 entry. You can do NAT exemption instead, as you do to your home

  1. remove the static entry (followed by clear xlate)

  Add - nat 0 access-list sheep (dmz)

  I suggest to use two acl different sheep, one for each interface.

  Ex: nonat_inside
