"The international standard, ISO/IEC 27002 (2005), defines in- formation security as the preservation of the confidentiality, integrity and availability of information (von Solms, R., & van Niekerk, J. 2013, as cited in ISO/IEC 27002, 2005, p. 1).
it will depend upon some legitimate user for authentication and establish a valid connection. Types of Session Hijacking Depending on the degree of involvement by the attacker, Session hijacking can be either active or passive in nature A passive attack uses sniffers on the network allowing attackers to gather information, The attacker will later use this data to log on as a legitimate user and take over privileges. Password sniffing is the simplest attack which will be performed once raw access to a network is
Cyber security involves preventative methods which are used to protect information from being stolen or attacked. Computer crime or cyber attack has become a widespread problem since the evolution of Information Systems. Cyber attack is a crime that involves a computer and a network.

There are various elements of an Information Security: 1) Application Security When you are using a computer it has to have a lot of applications.
Question 1.3 Active security attacks: masquerade, replay, modification of messages and denial of service Passive security attacks: release of message contents and traffic analysis. Question 1.4 Access control: prevention of unauthorized use of a resource that is service controls who can have access to a resource.
The internet and different forms of media and technology have been available and used by us for many years and has had a big impact on us, our economy and has contributed to our thinking process of how we view the world, ourselves, what we do and can do. Network security has similarities and differences associated with the media and technology we use every single day. There is a certain level of security that must be maintained in all services we use to protect us from high level threats that are growing stronger every single day. It is the media, technology and network securities’ responsibility to provide us with that protection. Network security is in almost all of the online services we use on a daily basis that serves to protect our personal
Such as browser security and network security. Many applications that run on a personal computer through the use of its operating systems may want to access the Internet for add-ons or to send out information about the system this can be with or without the administrators consent.
