Answer / ishita
A firewall is a part of the computer or network which
prevents unauthorized access to it.Firewalls are frequently
used to prevent unauthorized Internet users from accessing
private networks connected to the Internet.It regulates
traffic of the network of different trust levels.
On the other hand,Access Control List refers to rules that
are applied to port numbers or network daemon names that are
available on a host, each with a list of hosts and/or
networks permitted to use the service. Both individual
servers as well as routers can have network ACLs.
This way. ACL are the rules to be implemented for security
while firewall is he complete setup or mechanism.

A firewall is a secure and trusted machine that sits between
a private network and a public network.

Answer / pravin
Firewall-is a mechanism.
ACL is set of rule.

Answer / devroy
An ACL is a basic level of stateless packet filtering. If
that meets your (low) security requirements, then that's
fine.
A firewall generally includes stateful packet inspection.
This will provide a higher level of security than an ACL.
That said, you need to look at the specific
implementations, as what one vendor calls an ACL another
may call a firewall.
