Computer Security

Nowadays it is practically impossible to imagine our life without computer technologies and , consequently , without cybercrimes . Computers are not luxury , rather they become essential part of everybody 's life Actually , the term computer security ' is frequently used in contemporary world . Nevertheless , the content of every computer is at vulnerable unless it is connected to other computers on a network Developing and using computer network has become pervasive , especially using Internet resources and , therefore , the concept of computer security has expanded to denote issues pertaining to the networked use

of computers and their resources (Waxer 2007

Generally , computer security aims at protecting the following areas represented as CIA initials : confidentiality , integrity , and authentication or availability . Firstly , confidentiality suggests that mostly information is considered private and , thus , can 't be accessed by unauthorized parties . Further , confidentiality means privacy and secrecy of information . Breaches of confidentiality may vary from simply embarrassing to suggests that information should be protected from unauthorized changes and implications if authorized party is unaware of them . It is known that nowadays in many countries of the world hacking is prohibited by the law , though there are still many incident of breaching computer integrity , integrity of resources and databases . Finally , authentication suggests that users are who they claim to be , whereas availability suggests that all necessary resources should remain accessible to authorized parties . However , availability is also under attack . Denial of service ' is often highlighted in national and international news (Kinkus 2006

Other issues of computer security are non-repudiation and access control . Access control means that users are allowed to access only entitled services and resources and users aren 't denied legitimately expected resources . Non-repudiation suggests that a person when sending message is unable to deny that the sent message is his and consequently , a person when receiving message can 't deny that he receives it . However , beside the mentioned technical issues , computer security is , indeed , multifaceted and broad . As Jane Kinkus argues computer security touches draws from disciplines as ethics and risk analysis , and is concerned with s such as computer crime the prevention , detection , and remediation of attacks and identity and anonymity in cyberspace (Kinkus 2006

Despite the fact that integrity , authenticity and confidentiality are claimed to the cores of computer security systems , privacy seems to be more important for every Internet user . it is suggested that users have nothing to hide when they are registering with an Internet service or site , Internet privacy means that a personal information of every user must be protected from hacking even if information isn 't sensitive or intimate . Information in electronic format can be easily shared among computer networks , and because information from different computers and sources can be linked easily together forming in such a way individual information seeking habit , it is necessary to protect and to maintain control over information meaning to know what information is collected who use it and how it is used and , finally , what is the purpose of information collected (Kinkus 2006
