Term Explanation
ESPA 4.4.4
ESPA 4.4.4 is a protocol controlling wireless pagers. It uses ISO 1745, point-to-point
on RS232 as data link layer. The AlphaCom can use this in two ways:
 Output: Sends a “start paging” message to a wireless pager transmitter either
due to manual action by a user, or by automatic action such an activation of an
input (alarm).
 Input: The AlphaCom can be set up to look like a pager transmitter. The Alpha-
Com inspects the display text and generates events to the Event Handler which
do a range of actions. (“Fire Alarm protocol”). The ESPA 4.4.4 message is final-
ly forwarded
to one of the AlphaCom’s pager protocol outputs.
FEP
Front End Processor is a computer that extends and distributes connectivity to field
networks. The purpose is to off-load from the host computer the work of managing the
peripheral devices, transmitting and receiving messages, packet assembly and disas-
sembly, error detection, and error correction
Firewall
‘Firewall’ is a network security system that monitors and controls the incoming and
outgoing network traffic based on predetermined security rules.
HDB
History Database. Desigo CC History Database Server manages historical data col-
lected from subsystems and user activities. The Server uses Microsoft SQL to store,
manage and maintain the historic data of the system.
IEC The International Electrotechnical Commission is an international standards organiza-
tion that prepares and publishes International Standards for all electrical, electronic
and related technologies – collectively known as "electrotechnology".
IIS
Internet Information Services is an extensible web server created by Microsoft for use
with the Windows NT family. IIS supports HTTP, HTTP/2, HTTPS, FTP, FTPS, SMTP
and NNTP.
IPv4
Internet Protocol version 4 (IPv4) is the fourth version of the Internet Protocol (IP). It is
one of the core protocols of standards-based internetworking methods in the Internet,
and was the first version deployed for production in the ARPANET in 1983.
IPv4 is a connectionless protocol for use on packet-switched networks. It operates on
a best effort delivery model; in that it does not guarantee delivery, nor does it assure
proper sequencing or avoidance of duplicate delivery. These aspects, including data
integrity, are addressed by an upper layer transport protocol, such as the Transmis-
sion Control Protocol (TCP).
IPv6
Internet Protocol version 6 is the most recent version of the Internet Protocol (IP), the
communications protocol that provides an identification and location system for com-
puters on networks and routes traffic across the Internet. IPv6 was developed by the
Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of
IPv4 address exhaustion. IPv6 is intended to replace IPv4.
ISA-99/IEC
62443 Securi-
ty Level
ANSI/ISA 62443 is a series of standards, technical reports, and related information
that define procedures for implementing electronically secure Industrial Automation
and Control Systems (IACS). This guidance applies to end-users (i.e. asset owner),
system integrators, security practitioners, and control systems manufacturers respon-
sible for manufacturing, implementing, or managing IACS.
These documents were originally referred to as ANSI/ISA-99 or ISA99 standards, as
they were created by the International Society for Automation (ISA) and publicly re-
leased as American National Standards Institute (ANSI) documents. In 2010, they
were renumbered to be the ANSI/ISA-62443 series. This change was intended to align
the ISA and ANSI document numbering with the corresponding International Electro-
technical Commission (IEC) standards.
ISO
The International Organization for Standardization is an international standard-setting
body composed of representatives from various national standards organizations.
MNS
Mass Notification System is a platform that sends one-way messages to inform em-
ployees and the public of an emergency. Such systems can improve the safety and
security of an organization by providing alerts and real-time instruction during a crisis.
NTLM
In a Windows network, NT LAN Manager (NTLM) is a suite of Microsoft security proto-
cols that provides authentication, integrity, and confidentiality to users. NTLM is the
successor to the authentication protocol in Microsoft LAN Manager (LANMAN), an
older Microsoft product. The NTLM protocol suite is implemented in a Security Support
Provider, which combines the LAN Manager authentication protocol, NTLMv1,
NTLMv2 and NTLM2 Session protocols in a single package. Whether these protocols
are used or can be used on a system is governed by Group Policy settings, for which
different versions of Windows have different default settings. NTLM passwords are
considered weak because they can be brute-forced very easily with modern hardware.
NTP
‘Network Time Protocol’ is a networking protocol for time synchronization between
computers.
