SGACLs SGT CTS What order are the rules processed and are they stateful/stateless

Level 1

Could any one please confirm my following assumptions about the processing of SGACLs.

a) SGACLs on a ASA firewall are stateful and processed as normal ACL's on a per interface basis ?

b) SGACLs on IOS are processed  after normal  Ingress ACL'a and before Egress ACL's and are stateless ?

Thanks in advance.

a) The ASA Firewall does not use SGACLs. The ASA can however make use of Security Groups and SGT in policies configured at the ASA. This is known as Security Group Firewall. SGACLs are role-based policies with further granularity provided by Access Control Entries within the SGACL. These are configured at ISE and distributed to switches today and other devices such as routers in the very near future. When a policy is created at the ASA (SGFW), they are stateful.

b) SGACLs in IOS are processed at egress. If a standard ACL and an SGACL are both present, the standard ACL is processed first and then the SGACL.
