Security Threats, Challenges, Procedures and Policies in Information Systems

Nowadays, information systems as the hub of data processing and knowledge management play a vital and extensive role in digital societies. With the increasing development of technologies and the increase in the amount of information related to users and organizations, the security of information systems has become a complex and multi-dimensional challenge. In the field of security management in our information systems, we need a comprehensive understanding of all types of threats and challenges and providing approaches, policies, procedures and resources that are used to prevent security gaps, as well as protecting the system from all types of attacks affecting data and information. to be It is necessary to adopt a coherent and coordinated method to achieve the security processes of data and systems and it is necessary to understand the complexity of this category and provide comprehensive approaches based on its basic principles. Protection of information systems against unauthorized access or change to information, including storage, processing or transmission, and against denial of service to authorized users, is among the necessary measures to identify, document and deal with security threats in this area. According to the importance of the subject in this article, we will investigate the characteristics of security services of information systems in the environment of distributed networks, their importance and existing challenges and we will express effective policies and procedures to increase security in this area.
