Abstract

Information security presents the most important asset of all organizations and security agencies in general and national security in particular. Presently, there is a widespread global network and an interaction of information systems worldwide, therefore the means of communication and information technology play a crucial role in security of information. However, there is a need for an increased security of systems, due to various attacks on computer systems and networks, this as a result of identified weaknesses on current information technologies by the perpetrators. Cyber crimes, represent the most serious challenges not only for the national security and its institutions and agencies, but also for international security agencies and global security. The main characteristic of cyber crimes is their global effect. Being so, an international focus is required, considering that the perpetrators while committing the cyber crimes use various means that have no specific territorial boundary. Society develops along with information technology, the number of criminal offences against security of information included and cyber crimes increases. It is a disturbing fact that the cyber-crimes are more distinct and in conjunction with other criminal offences such as organized crime, cyber terrorism, fraud, threats and other criminal offences. Based on the higher risk that the cyber-crimes present against information security, all state mechanisms in general and security agencies in particular, need to develop their information defence architecture and its security. In this aspect, the purpose of securing the information is to ensure the availability of data system and confidentiality, so to disable unauthorised access to information and to preserve the confidentiality of information during its transmission through data verification and integrity.
