Cybersecurity is the practice of making the networks that constitute cyber space secure against intrusions. The aim is to maintain the confidentiality, the availability and integrity of information, by detecting interferences. Traditionally, cybersecurity has focused on preventing intrusions and monitoring ports. The evolving threat landscape, however, calls for a more dynamic approach. It is increasingly clear that total cybersecurity is impossible, unless government develops a cyber-security strategy. The aim of this chapter is to discuss government's dynamic approach to addressing challenges of cybersecurity. The chapter looks at the co-ordination of cyber-security activities so as to have a coordinated approach to cyber-crime. This chapter also highlights the idea of protecting sensitive data for the public good. It is generally accepted that technology has become indispensable in modern society. Government's cybersecurity presents a unique challenge simply because of the volume of threats that agencies working for government face on a daily basis.

The great revolution of technology and its fast growth have led to a cyber space increasingly vulnerable to cyber-attacks. For this reason, cyber security becomes paramount to protect our cyber space by presenting and implementing important solutions to protect sensitive data from malicious persons. Thereby various measures of protection have been developed and aim to minimize the risks and damages of attacks. Among them, cryptography plays a vital and crucial role in protecting sensitive transmissions and electronic exchanges through complex networks. Numerous scientific studies have emerged with the advent of the cloud and the Internet of Things (IoT); all of them have expressed a strong need for building secure, efficient and fast cryptosystems targeting confidentiality, integrity and authentication. The last two objectives are essentially built on hash functions which are the main components of many applications and secure networks. The purpose of this paper is to give recent advances of lightweight cryptographic solutions that meet the requirements of constrained systems, and to present a study, in terms of security, energy-consuming and efficiency, of the main hash functions standardized by NIST (National Institute of Standards and Technology). In the end, the paper will give a comparison between the studied hash functions aiming to come up with a recommendation of good lightweight hash functions suitable for implementation in an IoT framework.

Exchange Data

Cyberspace is a domain that uses the electronic and electromagnetic spectrum to store, modify, and exchange data through network and system-related physical infrastructures. Cyberspace is an endless space known as the Internet. Computer transactions, especially transactions between different computers, can be viewed as a space. Images and text on the Internet exist in cyberspace. The term is used in conjunction with virtual reality, giving the name of the imaginary place where a virtual object exists. If a computer creates a picture of a building that allows the architect to "walk in" and see what the nature of a design is, the building is said to be in cyberspace.Cybercrime is a series of organized criminal attack cyberspace and cyber security. Cybercrime such as Hacking into computer,this can be through a network system and clicking on unfamiliar links connecting to unrecognized Wi-Fi, downloading software and files to unsafe sites, consuming energy, electromagnetic radiation waves, and more. Cyber security is a serious problem and must be taken seriously as it has become a national concern. Currently, most electronic devices such as computers, laptops and cell phones come with built-in firewall security software, but even so, computers are not 100 percent accurate and reliable in protecting our data.

Abstract The more advanced digital economy and society a country has the more exposed it is to cyber threats. Consequently, countries with advanced digital economy and digital infrastructure naturally need to pay more attention to protecting cyber space. Today it is a national security issue and it can no longer be argued that cyber security is its indispensable part. Accordingly, a national cyber security strategy has to be built on national security strategy. That is the main reason for using the word “cornerstone” in the title of this study. The relation between national security and national cyber security means a specific context, which is one of the subjects of our examination in this study. Today, most countries have a cyber security strategy. However, these strategies are mostly static documents that do not or only partially can handle the dynamism that characterizes cyberspace. This paper focuses on the key issues that are needed for developing a usable cyber security strategy.
