-----I-----
IGMP. Internet Group Management Protocol allows a router to determine
which host groups have members on a given network segment.
IKE. Internet Key Exchange protocol provides automated key management
and is a preferred alternative to manual key management as it provides bet-
ter security. Manual key management is practical in a small, static environ-
ment of two or three sites. Exchanging the key is done through manual
means. Because IKE provides automated key exchange, it is good for larger,
more dynamic environments.
INSPECTION. The best option for Internet communications security is to
have an SMLI firewall constantly inspecting the flow of traffic: determining
direction, limiting or eliminating inbound access, and verifying down to the
packet level that the network traffic is only what the customer chooses. The
Netopia Gateway works like a network super traffic cop, inspecting and filter-
ing out undesired traffic based on your security policy and resulting configu-
ration.
interface. A connection between two devices or networks.
internet address. IP address. A 32-bit address used to route packets on a
TCP/IP network. In dotted decimal notation, each eight bits of the 32-bit
number are presented as a decimal number, with the four octets separated
by periods.
IPCP. Internet Protocol Control Protocol. A network control protocol in PPP
specifying how IP communications will be configured and operated over a
PPP link.
IPSEC. A protocol suite defined by the Internet Engineering Task Force to
protect IP traffic at packet level. It can be used for protecting the data trans-
mitted by any ser vice or application that is based on IP, but is commonly
used for VPNs.
ISAKMP. Internet Security Association and Key Management Protocol is a
framework for creating connection specific parameters. It is a protocol for
establishing, negotiating, modifying, and deleting SAs and provides a frame-
work for authentication and key exchange. ISAKMP is a par t of the IKE proto-
col.
