Which feature does Cisco TrustSec use to provide scalable, secure communication throughout a network?
Cisco TrustSec uses tags to represent logical group privilege. This tag, called a Security Group Tag
(SGT), is used in access policies. The SGT is understood and is used to enforce traffic by Cisco
switches, routers and firewalls . Cisco TrustSec is defined in three phases: classification,
propagation and enforcement.
When users and devices connect to a network, the network assigns a specific security group. This
process is called classification. Classification can be based on the results of the authentication
or by associating the SGT with an IP, VLAN, or port-profile (-> Answer 'security group tag
ACL assigned to each port on a switch' and answer 'security group tag number assigned to each
user on a switch' are not correct as they say ''assigned ... on a switch'' only. Answer 'security group
tag ACL assigned to each router on a network' is not correct either as it says ''assigned to each
router'').
