Work on the next phase of development of CIP Security is underway, which will add support for user authentication, non-repudiation, and device authorization. The ultimate roadmap for CIP Security development is to enable EtherNet/IP devices to become autonomous, taking responsibility for their own security and effectively securing themselves from attack Non-repudiation is a security service supporting the settlement of those disputes by creating, collecting, validating, and maintaining cryptographic evidence in electronic transactions , and many other systems (e.g., , ). It is a similar notion to authentication but has stronger proof requirements. Authentication only needs to convince the other party on the communication about the validity of. Non-repudiation is another security service commonly tied with accountability. In the context of enterprise web applications, confidentiality is concerned with the privacy of information that passes through or is stored inside the web application. Integrity ensures that the data used is free from deliberate or accidental modification. Authentication addresses verification of identities. When non-repudiation is applied to files transferred electronically between two parties, the sender cannot deny sending the message, and the recipient cannot deny receiving the message, thus proving the validity of the transfer to both parties. Non-repudiation can also be used in legal proceedings to prove where a file originated and that the data within the file has not been tampered with A Digital Workforce requires security, oversight and governance just as a human workforce does. 03 | Compliance and non-repudiation for financial services organizations Blue Prism Robotic Process Automation Software • Centrally managed user access control, limiting access to named individuals only • Role based access according to the principle of least privilege • Multi-actor security.

Non-repudiation provides evidence for the existence of a message or transaction and ensures its contents cannot be disputed once sent. Confidentiality ensures that only the people or processes authorized to view and use the contents of a message or transaction have access to those contents. In some situations, these properties are unneeded luxuries, but in others, the lack of one of these. In the case of biometrics, there are various resources involved such as humans (subjects or candidates), entities (system components or processes), and biometric data (information). The security requirements of confidentiality, integrity, authenticity, non-repudiation, and availability are essential in biometrics. Let us go through them briefly. Cyber security and information security are fundamental to Organizations are increasingly looking to secure information, manage cyber risk, ensure non-repudiation (someone cannot deny an action taken within an information system because the system provides proof of the action), and proper incident response to data breaches and other cybercrimes.
