To know the term cyber security first we need to understand the term cyber risk. Cyber risk is a group of risks that vary in technology, attack vectors, means and many more. We address such risks as a group mainly due to two similar characteristics:
1. They all have a potential great impact
2. They were all once considered improbable.
Cyber security is the collection of policies, tools, security safeguards, security concepts, risk management approaches, guidelines, training, actions, assurance, best practices and technologies which can be used to protect the cyber environment, several organizations and user's assets. Organization and user's assets can contain connected computing devices, infrastructure, personnel, services, telecommunications systems, applications and the totality of transmitted or stored information in the cyber environment. The general security objectives are
2. Integrity, which may include authenticity and non-repudiation
Cyberspace and its underlying infrastructure are susceptible to a wide range of risk stemming from both physical and cyber threats as well as hazards. The sophisticated cyber actors and nation states exploit vulnerabilities to steal information and money and are developing capabilities to disrupt, destroy or threaten the delivery of essential services. Now, a range of traditional crimes being executed through cyberspace such as the production and distribution of child pornography, child exploitation conspiracies, financial fraud and banking, intellectual property violations and many other crimes that mainly affects human and economic consequences.
To secure the cyberspace is the most difficult task due to several factors including the ability of malicious actors to operate from anywhere in the world, the difficulty of reducing vulnerabilities and consequences in complex cyber networks and the linkages between cyberspace and physical systems. As information technology becomes gradually integrated with physical infrastructure operations, which increases the risk of high consequence events that harms the services upon which our economy and the daily lives of millions of Americans depend.
