Yanıt Açıklaması: The process of interaction with virtual objects actually happens, but obviously can not be compared to what happens in the real world. In order to achieve certain results must be provided with a graphical user interface (representing the virtual world) and, in particular, three main variables should be handled: Space: This element can be changed at will. This possibility is the fact that it is a simulated environment and not the real space. Time: the perception of this magnitude can be very different depending on the situations in which a person is to find and what is happening around the observer. Interaction: environments and situations are not static but are generated depending on the user behavior, which is a protagonist of the events.

Yanıt Açıklaması: Security: It is a degree of protection of computer hardware and software from intentional or unintentional changes, uses, spoofing, spread of information over unauthorized people. • Reliability: It describes the ability of a system to maintain its function under a given set of conditions for a certain period of time. • Adversary: Any person, group or force that may intentionally infringe on the integrity, confidentiality and availability of information. • Security rules: Necessary regulations to keep the computer secure from malicious attacks. • Security breach: It is a software or hardware failure or incompleteness which could result in accessing the computer security.

Yanıt Açıklaması: Possible actions in risk management is eliminating or mitigating risk, assigning risk to a third party or transferring risk and accepting risk.  Suppose that the risk management has same set of actions for a computer based system that is connected to the Internet. There are numerous vulnerabilities in such a system so that malicious intruders can harm the system. Thus, the risk in this system is very high especially if the data is sensitive. To eliminate the risk, employing strong security primitives, e.g., installing an antivirus program, enabling a firewall and using trusted hardware and software will help to mitigate the risk. Again, transferring this risk to a third party is possible. Security can be guaranteed by a secure network service provider. For some situations, the system has to accept the risk since some websites provides minimal security that might lead a potential data loss or harm. Correct answer is C.

Yanıt Açıklaması: Trojan horses can be considered as a kind of spyware. The Trojan horse infection method to the computer is very similar to the virus infection method. Opening a link that comes by an e-mail or downloading a file from internet that we are not sure of its security of the source and opening it result in with infecting our computer with a Trojan.
