Remove some stubborn items ignored by Cisco PIX ACL firewall PCI

Hi,

I am not a Cisco guy but previously, ports 1433 and 1434 were open to allow SQL from our management company. Needless to say I put a stop to it since it was on machines in the card holder emviroment.However I'm not sure how he did it but he added them in a way that  they're being ignored by pics however when I run  are settings in the plain text I can see those lines are still there I'll post brief piece of our logs and  if someone could be so kind and point out anything in their that just seems horribly wrong it would be greatly appreciated. By the way, all of our machines are connected to this security appliance and is our only gateway at the time, it has two interfaces  so I plan to segregate or isolate those in the payment card holder environment. Should I based on the logs below also put a secondary security appliance I was thinking of one running in the next such as clearOS or centOS.  any insight in the logs you can give me would be greatly appreciated and any other best practices used  open source software for security management purposes would be greatly appreciated as well.

Thanks,



Building configuration...

The only pieces you need to be concerned with are these:

>access-group inbound in interface outside
This is the name of the access-list that is applied for traffic coming IN from OUTSIDE

access-list inbound permit tcp any any eq 82
access-list inbound permit tcp any any eq 15962
access-list inbound permit tcp any any eq 9000

These are the only 3 ports allowed in from outside to internal hosts

You can safely delete acl "100" and acl "any" because they are not applied anywhere
no access-list 100 permit icmp any any
no access-list 100 permit tcp any any eq 1433
no access-list 100 permit tcp any any eq 1434
no access-list 100 permit udp any any eq 1434
no access-list 100 permit udp any any eq 1433
no access-list any permit tcp any any eq 1433
no access-list any permit udp any any eq 1434

Additionally, if you don't have any static nat entries - don't know if you deliberatley left them out or if they just don't exist in the config - the inbound acl is not doing any good either and can also be safely deleted and removed from the interface. Access-lists simply don't do any good without the appropriate static port mappings.

Given the posted config, I would expect to see something like:
 static (inside,outside) tcp interface 82 10.63.104.xx 82 netmask 255.255.255.255
 static (inside,outside) tcp interface 15962 10.63.104.xx 15962 netmask 255.255.255.255
 static (inside,outside) tcp interface 9000 10.63.104.xxx 9000 netmask 255.255.255.255
