I have a Cisco ASA 5510 device and I am wondering as to the overview flow of traffic.  For example, a PIX would by default block incoming traffic but any outbound traffic initiated from the internal network is generally allowed unless it was specifically block a an access-list rule.  Does the ASA work in the same fashion?

As always, any advice or input in regards to this matter is greatly appreciated and thank you in advance for your time on this matter.

The ASA handles traffic in the same matter.  All traffic inbound must match an acl (except vpn if the sysopt commands are present).  All outbound traffic is allowed, until an ACL is applied to outbound, and then it must be specifically allowed.
