Security Level
information that define procedures for implementing electronically secure
Industrial Automation and Control Systems (IACS). This guidance applies to
end-users (for example, asset owner), system integrators, security
practitioners, and control systems manufacturers responsible 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 released 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 Electrotechnical
Commission (IEC) standards.
ISO
The International Organization for Standardization is an international
standard-setting body composed of representatives from various national
standards organizations.
MMS
Management station. In this document, it is intended as synonym of Desigo
CC.

Protection zone
Physically separated, private network. A fire detection system is a
physically separated network and forms a Protection zone. Network access
from outside of this zone into this zone is only allowed through a protective
component at the boundary to the Protection zone.
Public key certificate
In cryptography, a public key certificate, also known as a digital certificate
or identity certificate, is an electronic document used to prove the
ownership of a public key[1]. The certificate includes information about the
key, information about the identity of its owner (called the subject), and the
digital signature of an entity that has verified the certificate's contents
(called the issuer). If the signature is valid, and the software examining the
certificate trusts the issuer, then it can use that key to communicate
securely with the certificate's subject.[2] In email encryption, code signing,
and e-signature systems, a certificate's subject is typically a person or
organization. However, in Transport Layer Security (TLS) a certificate's
subject is typically a computer or other device, though TLS certificates may
identify organizations or individuals in addition to their core role in
identifying devices. TLS, sometimes called by its older name Secure
Sockets Layer (SSL), is notable for being a part of HTTPS, a protocol for
securely browsing the web.
In a typical public-key infrastructure (PKI) scheme, the certificate issuer is
a certificate authority (CA), usually a company that charges customers to
issue certificates for them. By contrast, in a web of trust scheme,
individuals sign each other's keys directly, in a format that performs a
similar function to a public key certificate.
The most common format for public key certificates is defined by X.509.
Because X.509 is very general, the format is further constrained by profiles
defined for certain use cases, such as Public Key Infrastructure (X.509) as
defined in RFC 5280.

RDP
Remote Desktop Protocol is a proprietary protocol developed by Microsoft,
which provides a user with a graphical interface to connect to another
computer over a network connection. The user employs RDP client
software for this purpose, while the other computer must run RDP server
software.
Standalone station
Standalone station with local connection for the computer.
Trusted network
The term trusted network refers to users or devices of an area which is
considered particularly secure or protected. Typically, this area is a private
section of a network. This private section of the network must be protected
from attacks by hackers and other security-related threats.
