Özet:

 










In recent years, networked computers are
extensively used in every aspect of our daily lives. Besides, the anonymous
structure of the Internet results in an increase in the number of attacks not
only for individual users but also for local area networks. Current attacks are
more sophisticated, and they are developed by experienced intruders with the
use of automated malware production methods. These organized intrusions can go
over the defense lines of the systems due to the weakness of the
detection/prevention mechanisms or carelessness of individual users. After
sneaking into the system, these attacks can work until they are detected, and
they can access many critical resources of the company. Earlier detection of
these attacks is very trivial issue for the security admins. This can be
accomplished by acquiring the signature (critical information) of the newest
attacks as early as possible. One suggested solution is the use of a Threat Information Sharing system, which
is set up between security firms and authorities. This approach enables the
distribution of the marks of the recent (zero-day) attacks and the development
of some proactive prevention mechanisms for them. The use of both peer to peer
and centralized sharing mechanisms have some inherited deficiencies. Therefore,
in this paper, a pure decentralized cyber security information sharing system
is proposed with the use of blockchain technology. A controlled decision-making
mechanism, authorization termination, and rule-sets maintenance are proposed to
make distributed decisions within the system. For making a decision, two smart
contracts should be used in the blockchain. One holds the positive votes while
the other holds the negative ones. Members of the system are able to access
cyber threat data by using company-related queries. The system can facilitate
the integration of many data sources into cyber security management system.
Additionally, it enables to collect in a single repository that can be accessed
for implementing real-time cyber security applications.
