Configuring Device Security Defining Access Control 5 • Protocol - Creates an ACE based on a specific protocol. The possible field values are: - ICMP - Internet Control Message Protocol (ICMP). The ICMP allows the gateway or destination host to communicate with the source host. For example, to report a processing error. - IGMP - Internet Group Management Protocol (IGMP). Allows hosts to notify their local switch or router that they want to receive transmissions assigned to a specific multicast group. - IP - Internet Protocol (IP). Specifies the format of packets and their addressing method. IP addresses packets and forwards the packets to the correct port. - TCP - Transmission Control Protocol (TCP). Enables two hosts to communicate and exchange data streams. TCP guarantees packet delivery, and guarantees packets are transmitted and received in the order the are sent. - EGP - Exterior Gateway Protocol (EGP). Permits exchanging routing information between two neighboring gateway hosts in an autonomous systems network. - IGP - Interior Gateway Protocol (IGP). Allows for routing information exchange between gateways in an autonomous network. - UDP - User Datagram Protocol (UDP). Communication protocol that transmits packets but does not guarantee their delivery. - HMP - Host Mapping Protocol (HMP). Collects network information from various networks hosts. HMP monitors hosts spread over the internet as well as hosts in a single network. - RDP - Remote Desktop Protocol (RDP). Allows a clients to communicate with the Terminal Server over the network. - IDPR - Matches the packet to the Inter-Domain Policy Routing (IDPR) protocol. - RSVP - Matches the packet to the ReSerVation Protocol (RSVP). - GRE -Matches the packet to the Generic Routing Encapsulation (GRE) protocol. - ESP -Matches the packet to the Encapsulating Security Payload (ESP) protocol.
