Cyber security is the activity of defending
information and information systems with suitable procedural and technological
security methods. Firewalls, antivirus software, and other technological answers
for safeguarding personal figures and computer networks are essential but not adequate
to ensure security. As our nation swiftly building its Cyber Infrastructure, it
is equally vital that we educate our people to work accurately with this
infrastructure. Cyber-Ethics, Cyber-Safety, and Cyber-Security issues need to
be assimilated in the educational process commencing at an early age. Security
counter measures assist ensure the confidentiality, disposability, and
integrity of information systems by preventing or mitigating asset losses from
Cyber security attacks. Recently cyber security has emerged as an established restraint
for computer systems and infrastructures with a focus on protection of valuable
information stored on those systems from adversaries who want to obtain, corrupt,
damage, destroy or disallow access to it. A wide range of metaphors was
considered, including those relating to: military and other types of conflict,
biological, health care, markets, three-dimensional space, and physical asset fortification.
These approaches were labeled “Heterogeneity”,
“Motivating Secure Behaviors” and “Cyber Wellness”. Cyber Security plays an important role in the expansion
of information technology as well as
Internet services. Our attention is usually drawn on “Cyber Security” when we receive
about “Cyber Crimes”. Our first thought on “National Cyber Security” therefore
starts on how good is our infrastructure for handling “Cyber Crimes”. This
paper focus on cyber security emerging trends. The paper also describes the
challenges faced and the importance of this technology in todays’ fast running

Internet is one of the fastest-growing zones of technical infrastructure
development. In today’s business environment, disruptive technologies such as
cloud computing, social computing, and next-generation mobile computing are primarily
changing how organizations utilize information technology for sharing
information and conducting commerce online. Today more than 80% of total
commercial transactions are done online, so this field requisite a high quality
of security for transparent and best transactions. The scope of Cyber Security
extends not only to the security of IT systems within the enterprise, but also
to the wider digital networks upon which they rely including cyber space itself
and critical infrastructures. Cyber security plays an important role in the
development of information technology, as well as Internet services. Ornamental
cyber security and protecting critical information infrastructures are
essential to each nation’s security and economic welfare. Society has become
dependent on cyber systems across the full range of human activities, including
commerce, finance, health care, energy,
entertainment, communications, and national defense. Recent exploration
findings also show that the level of public concern for privacy and personal
information has increased since 2016, Internet users are concerned that they
give away too much personal information and want to be forgotten when there is
no authentic grounds for retaining their personal information. Exploration of
the metaphors we use in the cyber security domain may help improve our thinking
and debate in four ways.
we may gain a clearer understanding of the value and boundaries of the concepts
we have mapped from other domains into the cyber security domain.
trying out less common or new metaphors may feed the imagination of researchers
and strategy developers.
metaphors that work particularly well might be established into a whole new
models or sets of concepts for approaching cyber security problems.
Fourth, a metaphor serves a heuristic purpose –bringing
clearer understanding of abstract concepts from the field of cyber security
into spheres with which the non-specialist may be more familiar.
Cyber security depends on the care that people take and the decisions
they make when they set up, maintain, and use workstations and the Internet.
Cyber-security covers physical protection (both hardware and software) of
personal information and technology resources from unlawful access gained via
Cyber security is the body of technologies, procedures
and practices designed to protect networks, computers, programs and data from outbreak,
damage or unauthorized access. In a computing context, security includes both cyber security and physical security. Confirming cyber
security requires coordinated efforts throughout an information system.
Elements of cyber security include:
Disaster recovery /
One of the most challenging elements of cyber
security is the quickly and constantly evolving nature of security risks. The
traditional approach has been to focus most resources on the most crucial
system components and protect against the major known threats, which
necessitated leaving some less important system components undefended and some
less dangerous risks not protected against. Such an approach is inadequate in
the current environment.
To deal with the current environment, advisory
organizations are promoting a more proactive and adaptive approach. The
National Institute of Standards and Technology (NIST), for
example, recently issued updated guidelines in its risk assessment framework
that suggested a shift toward continuous monitoring and real-time assessments.
According to Forbes, the global cyber security market reached $75 billion for
2015 and is likely to hit $170 billion in 2020.
The core functionality of cybersecurity involves protecting
information and systems from major cyber threats.
These cyber threats take many forms (e.g.,
application bouts, malware, ransom ware, phishing, exploit kits). Unfortunately, cyber adversaries have learned to launch automated and
sophisticated attacks using these maneuvers – at lower and lower costs. As a
result, keeping pace with cybersecurity strategy and operations can be a
challenge, particularly in government and enterprise networks where, in their
most troublesome form, cyber threats often take aim at secret, political,
military or infrastructural assets of a nation, or its people. Some of the
common threats are outlined underneath in more detail.
