What is an information security management system (ISMS)? 31 mins. Users are made aware of the importance of password security when they receive their system user accounts. Categories: The fundamental principles (tenets) of information security are confidentiality, integrity, and availability. Information security is achieved through a structured risk management process that: Identifies information, related assets and the threats, vulnerability and impact of unauthorized access. However, if our information is not secure, then it will cause problems or losses to us. To fully understand the importance of information security, you need to know the elements of an information system. If no threats existed, resources could be used exclusively to improve systems that contain, use, and transmit information. Information Systems for Business and Beyond was written by Dr. David Bourgeois and originally published in 2014 as part of the Open Textbook Challenge at the Saylor Foundation. Security should address the physical security of the buildings, equipment, and storage media as well as the data and informational assets retained by all health care organizations.
