In 1955, the general theory
is developed by Roos
Asbhy
Ross Ashby (London, 6 September
1903 – 15 November 1972) was an
English psychiatrist and a pioneer
in cybernetics, the study of
complex systems. His first name
was not used: he was known as
Ross Ashby. His two books, Design
for a Brain and An Introduction to
Cybernetics, were landmark works.
They introduced exact and logical
thinking into the nascent discipline
and were highly influential.
The general theory of systems idea developed by Karl
Ludwig von Bertalanffy in 1930, was a theme new that
caused great impact in the scientific community.
(September 19, 1901 – June 12, 1972) was an Austrian biologist known as one of the
founders of general systems theory (GST). This is an interdisciplinary practice that
describes systems with interacting components, applicable to biology, cybernetics,
and other fields. Bertalanffy proposed that the classical laws of thermodynamics
applied to closed systems, but not necessarily to "open systems," such as living
things. His mathematical model of an organism's growth over time, published in
1934, is still in use today. Bertalanffy grew up in Austria and subsequently worked in
Vienna, London, Canada, and the USA
Systems theory or systems science is the interdisciplinary study of systems in general, with the goal
of discovering patterns and elucidating principles that can be discerned from and applied to all types
of systems at all nesting levels in all fields of research. It can reasonably be considered a
specialization of systems thinking or as the goal output of systems science and systems engineering,
with an emphasis on generality useful across a broad range of systems (versus the particular models
of individual fields).
Examples of applications
• Systems biology
• Systems engineering
• Systems psychology
A model of set of interrelated principles and
concepts that explains and organization complex entities.
GST Facts
Bertalanffy expressed that real systems are exposed to, and work
together with, their enviromentes and can obtain qualitatively new
properties through development resulting in constant development

How is GST relevant to Us?
Information System
System consisting of the networks of all
comunication channels used within an
organization
Network Security System
The objective of network security includes protection of information and
property from theft, corruption, or natural disaster, while allowing the
information and property to remain accesible and productive to its
intenden users
