Network security[]

Rules "are the mechanism that determines which packets are allowed in and out of the network. The collection of rules that are being applied by network devices can also be referred to as Access Control Lists (“ACLs”). Threats are continually evolving, and as a result, rules can be automatically updated or swapped in switches, routers and firewalls by other management devices in the network that intake threat intelligence information."[3]
