New Mexico Administrative Code › Title 1 - GENERAL GOVERNMENT ADMINISTRATION › Chapter 12 - INFORMATION TECHNOLOGY › Part 11 - ENTERPRISE ARCHITECTURE › Section 1.12.11.7 - DEFINITIONS

Current through Register Vol. 35, No. 13, July 16, 2024
As used in this policy.
A.
Address block
means a
				contiguous group of internet protocol (IP) addresses.
B.
Addressing resolution
means a
				method for resolving differences between computer addressing schemes. Address
				resolution usually specifies a method for mapping network layer (layer 3)
				addresses to data link layer (layer 2) addresses.
C.
Address resolution protocol
means a protocol for mapping an IP address to a physical machine address that
				is recognized in the local network.
D.
Application administration
				account
means any account that is for administration of an
				application.
E.
Agency
				network
means networks that are managed by individual agencies and
				autonomous to state's core network.
F.
Architecture
means a
				logically consistent set of principles, policies, and standards that guide the
				engineering of state government's information technology systems and
				infrastructure in a way that ensures alignment with state government's business
				needs.
G.
American registry
				for internet numbers (ARIN)
means one of four regional internet
				registries. ARIN, founded in 1997, is a non-profit organization that registers
				and administers
IP numbers
for North America. ARIN is one of
				four regional internet registries.
H.
Class A network
means a
				binary address starting with 0; therefore, the decimal number can be anywhere
				from 1 to 126. The first 8 bits (the first octed) identify the network, and the
				remaining 24 bits indicate the host within the network.
I.
Class B network
means binary
				addresses that start with 10; therefore, the decimal can be anywhere from 128
				to 191; (the number 127 is reserved for loop-back and is used for internal
				testing on the local machine
).
The first 16 bits (the first two
				octets) identify the network, and the remaining 16 bits indicate the host
				within the network. An example of a class B IP address is 168.212.226.204,
				where "168.212" identifies the network and "226.204" identifies the host on
				that network.
J.
Class C
				network
means binary addresses that start with 11; therefore, the
				decimal number can be anywhere from 192 to 223. The first 24 bits (the first
				three octets) identify the network, and the remaining 8 bits identify the host
				within the network. An example of a class C IP address is 200.168.212.226,
				where "200.168.212" identifies the network and "226" identifies the host on
				that network.
K.
Common
				service
means a function that may be in use or deployed in multiple
				agencies, whether they are using the same programs or people to perform the
				function or not.
L.
Consolidated service
means a function that is performed by a
				common group of programs or people for multiple agencies, under centralized
				control and with agreed-upon standards, interfaces, and service level
				agreements.
M.
Consolidated
				service
means a function that is performed by a common group of programs
				or people for multiple agencies, under centralized control and with agreed-upon
				standards, interfaces, and service-level agreements.
N.
Cost recovery service
means a
				service that is charged back to the consumers of the service at a fully loaded
				rate to allow the provider to recoup all associated costs with providing the
				service.
O.
Current
				technology
means components that have met requirements of the EA - those
				components that should be used in deployment of technology solutions.
P.
Emerging technology
means
				products that have potential to become current components.
Q.
Enterprise
means that for
				this document, 'enterprise' refers to the executive branch of the government of
				the SoNM, including all business processes and IT support systems.
R.
Enterprisearchitecture
defines an enterprise-wide, integrated set of components that incorporates
				strategic business thinking, information assets, and the technical
				infrastructure of an enterprise to promote information sharing across agency
				and organizational boundaries; the enterprise architecture is supported by
				architecture governance and the allied architectures of business, information,
				technology, and solution architectures.
S.
Enterprise project
means a
				project with the purpose of delivering new or modifying existing services to
				many stakeholders within the state.
T.
General funded service
means
				a SoNM service funded through general fund tax dollars.
U.
Internet protocol (IP)
				address
means a 32-bit address used to indicate a specific network and
				host on the internet or within a local network. The address is usually seen in
				decimal representation in the form
nnn.nnn.nnn.nnn
, where
nnn
can be any number between 0 and 255.
V.
Internet protocol security
				(IPSec)
means a set of protocols developed by the internet engineering
				task force (IETF) to support secure exchange of packets at the IP layer by
				encrypting a 1.18.361 NMAC authenticating all IP packets. IPsec has been
				deployed widely to implement virtual private networks.
W.
Internet protocol version 6
				(IPv6)
means a standard intended to replace the previous standard, IPv4,
				which only supports up to about 4 billion addresses (4 x 109), whereas IPv6
				supports approximately 3.4 x 1038 addresses, equivalent to
				430,000,000,000,000,000,000 unique addresses per square inch of earth. The root
				domain has been changed to support both IPv6 and IPv4. It is expected that IPv4
				will be supported until about 2025 to allow for bugs to be worked in support of
				new IP and wireless devices.
X.
Other-funded service
means a SoNM service that receives funding
				from non-SoNM sources or state funds other than the general fund, such as the
				road fund, federal government, or a locality.
Y.
Network address translation
means an internet standard that enables a local area network (LAN) to use one
				set of IP addresses for internal traffic and a second set of addresses for
				external traffic. A NAT box located where the LAN meets the internet makes all
				necessary IP address translations by keeping IP addresses of network packets
				passing through a router or firewall. Hosts, which are behind a NAT-enabled
				gateway, do not have end-to-end connectivity. NAT serves three main purposes:
(1) provides a type of firewall by hiding
				internal IP addresses;
(2) enables
				a company to use more internal IP addresses (since they are used internally
				only, there is no possibility of conflict with IP addresses used by other
				companies and organizations); and
(3) allows a company to combine multiple ISDN
				connections into a single internet connection.
