Management plane:В The management plane manages traffic that is sent to the Cisco firewall device and is composed of applications and protocols such as SSH and Simple Network Management Protocol (SNMP).The three functional planes of a network each provide different functionality that needs to be protected. For the purposes of this document, all mentions of 'Cisco firewall' refer explicitly to the Cisco ASA Adaptive Security Appliances, though the concepts may apply to other firewall and security devices. In addition, this document provides an overview of each included feature and references to related documentation. This document is structured around security operations (best practices) and the three functional planes of a network. The functions of network devices are structured around three planes: management, control, and data. This document provides administrators and engineers guidance on securing Cisco firewall appliances, which increases the overall security of an end-to end architecture.
