Glossary HTTP HTTPS Hypertext Transfer Protocol. A protocol used by browsers and web servers to transfer files. When a user views a web page, the browser can use HTTP to request and receive the files used by the web page. HTTP transmissions are not encrypted. HTTP over SSL. An SSL-encrypted version of HTTP. I IANA ICMP IETF IGMP IKE IKE Extended Authentication IKE Mode Configuration ILS IMAP implicit rule IMSI inside Internet Assigned Number Authority. Assigns all port and protocol numbers for use on the Internet. Internet Control Message Protocol. Network-layer Internet protocol that reports errors and provides other information relevant to IP packet processing. The Internet Engineering Task Force. A technical standards organization that develops RFC documents defining protocols for the Internet. Internet Group Management Protocol. IGMP is a protocol used by IPv4 systems to report IP multicast memberships to neighboring multicast routers. Internet Key Exchange. IKE establishes a shared security policy and authenticates keys for services (such as IPSec) that require keys. Before any IPSec traffic can be passed, each FWSM must verify the identity of its peer. This can be done by manually entering preshared keys into both hosts or by a CA service. IKE is a hybrid protocol that uses part Oakley and part of another protocol suite called SKEME inside ISAKMP framework. This is the protocol formerly known as ISAKMP/Oakley, and is defined in RFC 2409. IKE Extended Authenticate (Xauth) is implemented per the IETF draft-ietf-ipsec-isakmp-xauth-04.txt ("extended authentication" draft). This protocol provides the capability of authenticating a user within IKE using TACACS+ or RADIUS. IKE Mode Configuration is implemented per the IETF draft-ietf-ipsec-isakmp-mode-cfg-04.txt. IKE Mode Configuration provides a method for a security gateway to download an IP address (and other network level configuration) to the VPN client as part of an IKE negotiation. Internet Locator Service. ILS is based on LDAP and is ILSv2 compliant. ILS was developed by Microsoft for use with its NetMeeting, SiteServer, and Active Directory products. Internet Message Access Protocol. Method of accessing e-mail or bulletin board messages kept on a mail server that can be shared. IMAP permits client e-mail applications to access remote message stores as if they were local without actually transferring the message. An access rule automatically created by the FWSM based on default rules or as a result of user-defined rules. International Mobile Subscriber Identity. One of two components of a GTP tunnel ID, the other being the NSAPI. See also NSAPI. The first interface, usually port 1, that connects your internal, "trusted" network protected by the FWSM. See also interface, interface names. GL-8 Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Configuration Guide using ASDM OL-20748-01
