The document discusses the concept of security, its historical origins, and its fundamental importance to human safety and societal development. It categorizes security into various types, including traditional, national, political, environmental, economic, water and food security, and network security, explaining their roles and significance. The text emphasizes the necessity of security in protecting individuals and resources from different threats and crises.

1. Security
Concept, Types & Role Group-21

2. Concept of Security
• The origin of security is as old as man himself. From the
moment of creation up till today, humans have biologically
sort after safety. No wonder the great psychologist Abraham
Maslow identified security and safety as one of the
fundamental needs of humans. Whether its security against
emotional, physical or natural threats, dangers and risks, we
all want to be safe. The need for security is as basic as the
need for food.

3. Concept of Security
• Fundamentally, security has to do with the
presence of peace, safety, gladness and the
protection of human and physical resources
or absence of crisis or threats to human
dignity, all of which facilitate development
and progress of any human. society. The
concept of security has become a
preoccupation for the decades.

4. Why Do We need to be Safe?
• Fear of the Loss of Life
When it comes to death, whether old or young, no one will intentionally want to die early in
life. Despite knowing that death is inevitable, we do our best to make sure we are safe, so we
can make more impact in the lives of our families and friends. Like the human’s instinct, the
service of security helps to reduce the fear of losing one’s life or even getting kidnapped.
• Fear of the Loss of Properties
Losing one’s property alone is not something anyone wants to experience. Let look at the
property that could be lost to theft; goods, vehicles, money and other valuables can get lost –
this is enough reason to get security. g these valuables can be hijacked.
The following are some of the reasons why we need security as humans.

5. Types of Security
• Traditional Security
• National Security
• Political Security
• Environmental Security
• Water and Food
Security
• Economic security
• Network Security

6. Traditional Security
• In traditional concept of Security, the
greatest danger to a country is from military
threats. On the other hand the non-
traditional security consists of dangers such
as terrorism, human rights, global poverty and
health epidemics. The creation and
sustenance of alliances belong to the
category of traditional security.

7. National Security
• The dictionary meaning of security is
protection from harm. National security
is the protection of state and citizens
from all kinds of national crises using
political, military, economic or
diplomatic power. The two aspects of
National Security are Internal and
External Security.

8. National Security
Internal Security
Internal Security refers to upholding national law and
maintenance of peace, law and order within a country’s
territory. Internal security, is the act of keeping peace within
the borders of a sovereign state or other self-governing
territories, generally by upholding the national law and
defending against internal security threats. Responsibility
for internal security may range from police to paramilitary
forces, and in exceptional circumstances, the military itself.
There are several aspects of Internal security such as
domestic peace, rule of law, public safety, peaceful co-
existence and communal harmony.
External Security
External Security refers to
security against aggression
by foreign countries.
External Security comes
under Ministry of Defense.
There are several historical
and non-historical reasons
for causing these problems
such as hostile neighbours,
porous borders, lethal non-
state actors and so on.

9. Political Security
• Political security was defined as the prevention of government
repression, systematic violation of human rights and threats from
militarization. It is right to give political parties to running in the country
work independent framing manifesto to govern the country according
to constitution of that country. Political security can thus mean that
your people are safe from harm; that your political party is safely in
power.
Environmental Security
• Environmental security is the state of environment dynamics that
includes restoration of the environment damaged by military actions, and
resource scarcities, environmental degradation, and biological threats that
could lead to social disorder and conflict. It may focus on the impact of
human conflict and international relations on the environment, or on how to
solve environmental problems cross state borders.

10. Formal/Public Security
Public security, on the other hand, are police, detectives, and other
public sector security officials. They are highly regulated and
funded by the government. Public security restricted by law and
politics.
Informal/Private Security
Simply put, private security is security offered by private
companies. They have strict training and certification standards but
do not have the same restrictions that public security may have.

11. Economic security
• Economic security or financial security is the condition of having
stable income or other resources to support a standard of living now
and in the foreseeable future. It includes: probable continued solvency.
• Economic security is composed of basic social security, defined by
access to basic needs infrastructure pertaining to health, education,
dwelling, information, and social protection, as well as work-related
security.
Water and Food Security
• Water is key to food security. Crops and livestock need water to grow.
Agriculture requires large quantities of water for irrigation. While feeding the
world and producing a diverse range of non-food crops such as cotton, rubber
and industrial oils in an increasingly productive way, agriculture also confirmed its
position as the biggest user of water on the globe.
• The world is running out of clean, fresh water to feed—and nourish—a
growing global population, ensure sustainable development, and maintain the
health of our planet. Therefore, better water management is crucial to global
food and nutrition security.

12. Network Security
In this modern era, organizations greatly rely on computer networks to share information
throughout the organization in an efficient and productive manner. Organizational
computer networks are now becoming large and ubiquitous. Assuming that each staff
member has a dedicated workstation, a large scale company would have few thousands
workstations and many server on the network.
It is likely that these workstations may not be centrally managed, nor would they have
perimeter protection. They may have a variety of operating systems, hardware, software,
and protocols, with different level of cyber awareness among users. Now imagine, these
thousands of workstations on company network are directly connected to the Internet.
This sort of unsecured network becomes a target for an attack which holds valuable
information and displays vulnerabilities.
