What is the difference between access control list and firewall?
A firewall has one main use and purpose and that is to examine traffic passing through a part of the network and make decisions about what to let through and what to block. ACLs do stateless inspection, which means that the access list looks at a packet and has no knowledge of what has come before it.

How to define access control list?
An access control list (ACL) is a list of access control entries (ACE). Each ACE in an ACL identifies a trustee and specifies the access rights allowed, denied, or audited for that trustee. The security descriptor for a securable object can contain two types of ACLs: a DACL and a SACL. A discretionary access control list (DACL) identifies the trustees that are allowed or denied access to a securable object.
